Methods: We

analyzed GW 572016 the urinary soluble Klotho levels in a cohort of 161 patients with stage 1–5 CKD and assessed the relationships between the urinary Klotho-to-creatinine ratio (Klotho/Cr), proteinuria and the kidney function. The patients were prospectively followed for two years to monitor for doubling of the baseline serum creatinine concentration and the initiation of renal replacement therapy. Results: Median urinary Klotho/Cr level was 0.35 μg/gCr (0.03–1.64) at baseline. The urinary Klotho/Cr level was positively correlated with eGFR and proteinuria and negatively correlated with changes in proteinuria during the follow-up period. The 117 patients followed for two years were categorized into two groups according to the baseline median urinary Klotho value. The 23 patients had progressed to renal end point. Renal survival was significantly lower in the patients with a urinary Klotho/Cr

ratio of ≤0.321 μg/gCr than in those with a urinary Klotho/Cr ratio of >0.321 μg/gCr (p = 0.0398). A Cox regression analysis adjusted selleck chemicals llc for age, gender, hypertension, diabetes, dyslipidemia, eGFR, proteinuria, hemoglobin, phosphate, fibroblast growth factor 23 and renin-angiotensin system blockade showed that a urinary Klotho/Cr ratio of >0.321 was significantly associated with a reduced risk for the renal end point. The adjusted odds ratio for a urinary Klotho/Cr ratio of >0.321 was 0.59 (95% confidential interval: 0.35–0.96; p = 0.0334). Conclusion: In this study, lower levels of urinary Klotho were significantly associated with renal outcomes, suggesting that a lower urinary Klotho level can serve as a novel biomarker for CKD progression.

Material and Methods: A cross-sectional non-hospital based study on randomly selected 52 subjects from general population. Maltron BIOSCAN analyzer 915/916 was used for evaluating water cpmpartments, creatinine clearance and GFR. Biochemical tests included hemoglobin, blood sugar random, liver function test (Bilirubin, SGPT, SGOT and Alkaline phosphatase), renal function test (serum creatinine and BUN), uric acid and urine microscopy. Blood pressure was checked.Total body water (TBW) derived using BIA was validated against Hume etal’s equations for estimating TBW. Results: Out of 52 subjects 24 (46.

As described above, one remarkable result

of the analysis of the GM polymorphism is the observation of abrupt frequency changes between different continental areas worldwide. By subdividing the world into 10 continental or sub-continental regions (sub-Saharan Africa, North Africa, Europe, West Asia, Northeast Asia, Southeast Asia, Oceania, Circum-Arctic, North and Central America, and South America), we found a proportion of genetic diversity due to differences among regions of about 39%.12 This is much higher Tyrosine Kinase Inhibitor Library price than generally found (albeit based on a different subdivision of the world and different numbers of groups) for allozymes and DNA markers, of the order of 10–15%,22–24 and 3–7% for most HLA loci.25 Extreme values (up to 88%) of human genetic diversity among the main geographic regions have only been found for strongly selected biological traits like skin pigmentation, whereas craniometric

traits also fall within the range of neutrally evolving genetic markers.26,27 We may ask ourselves whether, because of the immunological function of IgG molecules expressing GM allotypes, the GM polymorphism is subject to some kind of (directional) selection. Indeed, some studies have suggested that GM haplotypes were involved in susceptibilities to autoimmune diseases (see ref. 28,29 check details for a review) and infectious diseases like malaria30–32 or filariasis.33 However, conclusive evidence

for disease associations has not been found. Moreover, we did not detect any departure from selective neutrality by using Ewens–Watterson’s tests (with Bonferroni’s correction) on 82 populations tested for GM worldwide.12 Therefore, our explanation of the unusual apportionment of genetic diversity observed for the GM polymorphism is, first, that this system has been tested by serological typing, thereby providing only a broad description of its molecular variation, and, second, as explained above, that the frequencies of the most frequent haplotypes Methane monooxygenase in each geographic region are over-estimated because most GM frequencies were estimated by following a parsimonious approach considering a minimum number of haplotypes deduced ‘by hand’ from the phenotypic distributions. As a consequence, the proportion of genetic variation observed among regions has probably also been over-estimated. On the other hand, the most frequent GM haplotypes defined by serology may be seen as broad GM haplogroups including phylogenetically related haplotypes, an interpretation that is sustained by previous analyses performed at the DNA sequence level34 and that recalls the definition of Y-chromosome (non-recombining region, or NRY) haplogroups.35 The Y-chromosome markers deviate from other DNA markers in being, like GM, highly structured at the global scale: according to Hammer et al.

We examined the role of Th2 cytokines, namely IL-4 and IL-10, in the protective effect of OM-85. Using genetically deficient mice and cytokine-neutralizing monoclonal antibodies, we have demonstrated that the therapeutic effect does not involve the Th2 cytokine IL-4 but is tightly dependent upon transforming growth factor (TGF)-β. Natural killer (NK) T cells also participate in the therapeutic effect, as CD1d−/− NOD mice www.selleckchem.com/products/Dasatinib.html are partially resistant to the protective effect of OM-85 [45]. Importantly, key mechanistic

results were that OM-85 induced the production of IL-12 by DCs and of IL-10 essentially by B lymphocytes. It is important to stress at this point that there appears to be a tight dependency between the TGF-β-producing ability of OM-85 and the protective effect on the disease, GSI-IX in vitro because when a neutralizing anti-TGF-β antibody was administered immediately after OM-85, the protective effect of the drug was lost [45]. The second important finding was that, in spite of the fact that OM-85 is a mixture of several bacterial products, its protective effect on diabetes development appears to be mediated by components targeting TLR-4 [45]. Supporting this conclusion further are the recent data we obtained using in vivo instead of the intact bacterial extract:

well-defined TLR-4 ligands OM-174-DP and OM-197-MP-AC that are currently under clinical development as adjuvants [46–50]. These are mimics of the lipid A portion of lipopolysaccharide (LPS), possessing many of the biological activities of LPS but devoid of its toxic effects [46,48,50]. OM-174-DP

and OM-197-MP-AC protected NOD mice significantly from the development of diabetes, similarly to Dapagliflozin OM-85. As with OM-85 the therapeutic activity correlated with an effect on B lymphocytes, leading to their proliferation and IL-10 secretion. The immunopharmacology of TLR ligands is just at its beginning, but the results appear encouraging enough to invest in this novel immune intervention avenue. None of the authors has conflicts of interest to declare, or any relevant financial interest, in any company or institution that might benefit from this publication. “
“Haematopoietic humanization of mice is used frequently to study the human immune system and its reaction upon experimental intervention. Immunocompromised non-obese diabetic (NOD)-Rag1–/– mice, additionally deficient for the common gamma chain of cytokine receptors (γc) (NOD-Rag1–/– γc–/– mice), lack B, T and natural killer (NK) cells and allow for efficient human peripheral mononuclear cell (PBMC) engraftment. However, a major experimental drawback for studies using these mice is the rapid onset of graft-versus-host disease (GVHD).

In the Cox regression model, intravenous methylprednisolone pulse therapy had a significant effect on relapse (hazard Selleck Epigenetics Compound Library ratio, 2.39 (95% confidence interval 1.11–5.15), P = 0.026). Conclusion:  Intravenous methylprednisolone pulse followed by oral prednisolone therapy shows an

earlier responsiveness but a much more frequent relapse compared with conventional oral prednisolone alone therapy for the first attack of adult-onset MCNS. “
“Aim:  Encapsulated peritoneal sclerosis is characterized by neoangiogenesis and fibrosis. Octreotide, a somatostatin analogue is a well-known antifibrotic, antiproliferative and anti-angiogenic agent. The aim of the study is to evaluate the effects of octreotide in encapsulated peritoneal sclerosis-induced neoangiogenesis and fibrosis and compare the results with resting. Methods:  Non-uraemic Wistar-Albino male rats (n = 35) were divided into four groups. Group I, control rats, received 2 mL isotonic saline i.p. daily for 3 weeks. Group II, received daily i.p. 2 mL/200 g injection of chlorhexidine gluconate (0.1%) and ethanol (%15) dissolved FK506 price in saline for 3 weeks. Group III, chlorhexidine gluconate for 3 weeks plus an additional 3 weeks without any treatment (rest), to a total of 6 weeks. Group IV, chlorhexidine gluconate for 3 weeks plus an additional 3 weeks octreotide, 50 mcg/kg bodyweight s.c., for a total of 6 weeks. Results:  Octreotide

significantly reversed ultrafiltration capacity of peritoneum with decreasing inflammation, neoangiogenesis and fibrosis compared to the resting group. Octreotide also caused inhibition of dialysate transforming growth factor-β1,

vascular endothelial growth factor and monocyte chemotactic protein-1 activity and improved mesothelial cell cytokeratin expression. Peritoneal resting has no beneficial effects on peritoneum. Conclusion:  In conclusion, octreotide may have a therapeutic value in peritoneal dialysis patients who suffer from encapsulated peritoneal oxyclozanide sclerosis. “
“Background:  During haemodialysis, some patients experience intensification of symptoms of haemodialysis access-induced distal ischaemia. Aim of this study is to compare the effects of two different regimens of arterial blood flow in patients with an arteriovenous access. Methods:  A questionnaire identified 10 patients that subjectively experienced ischaemic symptoms during haemodialysis. Systolic blood pressure, heart rate, finger pressure (Pdig), finger temperature (Tdig), oxygen saturation and ischaemic scores were monitored during two different arterial blood flow dialysis sessions. Results:  Before dialysis, Pdig and Tdig of the arteriovenous access hand were significantly lower compared with the other hand. Haemodialysis induced a drop of Pdig in both hands. All changes in Pdig occurred independent of the artificial kidney’s blood flow level.

Amphotericin B-Desoxycholat weist deutliche Nebenwirkungen bei i.v. Therapie auf. Die nordamerikanische Infectious Disease Society (IDSA) Guideline von 2008 empfiehlt Amphotericin B-Desoxycholat aufgrund substantieller Toxizitäten nur noch für Regionen mit eingeschränkten Ressourcen, die in nicht entwickelten

Ländern Pifithrin-�� vorliegen können. Liposomales Amphotericin B in der Standarddosierung (3 mg/kg) weist ähnliche Ansprechraten wie Voriconazol in der Erstlinientherapie der invasiven Aspergillose auf. Allerdings fehlt ein direkter Vergleich mit Voriconazol aus randomisierten Studien. In der Zweitlinientherapie nach Versagen oder Intoleranz der Primärtherapie wurden in den letzten Jahren Caspofungin, Micafungin und Posaconazol untersucht. Kombinationstherapien werden bei refraktären Fällen einer invasiven Aspergillose im klinischen Alltag eingesetzt. Ergebnisse aus vergleichenden prospektiven kontrollierten Studien einer Kombinationstherapie gegenüber einer Monotherapie werden erst nach 2010 zu erwarten sein. Invasive

fungus infections caused by aspergillus spp. TSA HDAC cell line occur most frequently in immunocompromised patients. A high infection-associated death rate of up to and over 50% is attributed even today to these fungi. The disease in humans is caused mainly by Aspergillus fumigatus, Aspergillus flavus and Aspergillus niger. Other species, for example, Aspergillus terreus or Aspergillus nidulans are quantitatively less prevalent. Evidence based treatment of invasive aspergillosis has become safer and more effective within the last ten years through the introduction of the new azoles and the echinocandines. Voriconazole has become the medication of choice for initial therapy. The efficacy of voriconazole is well documented, to include the treatment of disseminated infections of the central nervous system. Amphotericin B-desoxycholate is associated with definite side-effects in intravenous therapy. On the grounds of its substantial toxicity, the North American Infectious Disease Society’s (IDSA) Guidelines of 2008 recommend amphotericin B-desoxycholate for regions with restricted resources only,

which could be the case in underdeveloped countries. Liposomal amphotericin B in the daily standard dose of 3 mg/kg offers a rate of response similar to the one with voriconazole in the first-line treatment of invasive aspergillosis. However, a direct see more comparison with voriconazole on the basis of randomized studies is not available. As a secondary therapeutic treatment, in case of failure or intolerance of the primary treatment, caspofungin, micafungin and posaconazole have recently been under study. Both the echinocandines and posaconazole have proven effective in daily clinical practise. In refractory cases of invasive aspergillosis a combination therapy has been employed clinically. The results of prospective comparative controlled studies on combination therapy versus monotherapy will not be available until after 2010.

Microglia are unique among the major cell types of the central nervous system (CNS) in being not derived from the neuroectoderm. Ultimately derived from myeloid precursors, they are representatives of the monocyte/macrophage series of cells, and can be regarded as the resident cells of the innate immune system in the CNS. ‘Neuroinflammation’, in the form of activation BMS 354825 of microglia, is an almost ubiquitous feature of diseases of the CNS. Is neuroinflammation simply a reaction to tissue damage and disease or, alternatively, is it an integral component of CNS disease,

promoting neuronal and synaptic damage and important in pathogenesis? Consideration of organs other than the brain certainly tells us that chronic inflammation is harmful, causing tissue damage and fibrosis. Examples include inflammation of synovial joints resulting in arthropathy and damaging chronic inflammation of the liver, pancreas, gastrointestinal tract and lungs. Early proponents of the concept that neuroinflammation

is important in the pathogenesis of neurodegenerative diseases such as Alzheimer’s disease (AD) include Griffin and McGeer in the 1980s. Initially, such views were controversial and met with considerable scepticism but in subsequent years, as new evidence emerged, the role www.selleckchem.com/products/DAPT-GSI-IX.html of neuroinflammation in AD has been given serious consideration by many others. An important stage was in the 1990s when epidemiological studies of use of non-steroidal anti-inflammatory drugs began to provide evidence of a role for neuroinflammation in the pathogenesis of AD. More recently, this concept has been given

further support by genome-wide association studies of AD demonstrating that variation in genes encoding several inflammation-related proteins influences risk of AD development. In this special issue of Neuropathology and Applied Neurobiology, we are privileged to have reviews written by international leaders in the field of neuroinflammation to provide an update and new insights into the role of microglial activation in ageing and in neurodegenerative disease. In the first review, we set the scene in describing how in the normal Dapagliflozin CNS microglia appear quiescent and downregulated, and how they become activated in disease states. Evidence mainly from in vitro and rodent studies indicates that microglia can exist in different activation states, prompted by different stimuli and with different functional consequences. We discuss to what extent these different activation states can be identified in the human brain, and raise the question as to whether manipulation of the microglial state of activation may in future be of therapeutic use. In the second review, Diana Norden and Jonathan Godbout discuss evidence of alterations of microglia in the ageing process, rendering them primed or sensitized to react to stimuli and with the balance of cytokine expression biased towards a pro-inflammatory state.

We previously identified optineurin (OPTN) as a novel causal gene

of amyotrophic lateral sclerosis (ALS).[1] OPTN mutations result in autosomal dominant and recessive traits. For example, an E478G mutation is considered to result in dominant inheritance, and Q398X recessiveness. Elucidating the clinicopathological features of ALS associated with OPTN mutations (OPTN-ALS) could help interpret the role of OPTN in ALS pathogenesis. Recently, we described the clinicopathology of a family with the heterozygous selleck kinase inhibitor E478G OPTN mutation, which showed widespread transactivation response (TAR) DNA-binding protein 43 (TDP-43) pathology.[2] Here we report the clinicopathological findings of two ALS patients homozygous for the Q398X OPTN mutation. A 52-year-old Japanese woman presented with progressive bulbar palsy. Her medical history was significant

CT99021 cell line for glaucoma. Her parents were first cousins. She had no family history of either neurological diseases or glaucoma. Most of the patient’s reflexes presented a hyper response; the snout reflex was the only pathological reflex present. The patient was diagnosed with possible ALS with bulbar onset, according to the revised El Escorial criteria. She later developed symptoms of forced crying and laughter, and marked deformity of the hands, possibly because of dystonia (Fig. 1A). Brain MRI revealed temporal lobe and motor cortex

atrophy (Fig. 1B,C). Phosphatidylinositol diacylglycerol-lyase The patient died of respiratory failure at age 61 and an autopsy was performed. A 44-year-old Japanese woman presented with right upper limb weakness and atrophy. She had no history of glaucoma. Her family history was negative for neurological diseases and glaucoma. Her parents were not consanguineous. The patient’s reflexes presented a hyper response in the lower extremities and no pathological reflexes were present. Her cognitive function was normal. Needle electromyography showed both active and chronic denervation in the cervical, thoracic, lumbosacral and bulbar regions. These results supported the diagnosis of laboratory-supported probable ALS according to the revised El Escorial criteria. The patient died of respiratory failure at age 48 and autopsy was not performed. This study was approved by the ethics committee of The Tokushima University Hospital and all participants provided written informed consent. We previously isolated DNA from the venous blood of ALS patients and detected a homozygous Q398X in the OPTN gene.[1] A haplotype region of 0.9 megabases that contained the OPTN gene was found to be shared by patients.[1] Mutations of SOD1, TARDBP, FUS, VAPB, ANG, Dynactin, CHMP2B, STXN, in Patient 1 and SOD1, TARDBP, FUS in Patient 2 were excluded.

Inhibition of uPAR BMS-777607 chemical structure mRNA was most noticeable. In the control experiment, TNF-α was neither induced by TGF-β nor inhibited by Smad3 siRNA. The effect of known inhibitors of TGF-β signalling, Smad3 inhibitor (SIS3), ALK-5 inhibitor

(SB-431542) and macrolides (erythromycin, clarythromycin and EM703) on TGF-β signalling and induction of uPAR was assessed next. MN were cultured in Accel medium at 1.5 × 105/well in the presence and absence of inhibitors of TGF-β signalling. MTB H37RvL (10 μg/ml) or PPD (10 μg/ml) were then added and cells harvested 24 h later in Qiagen RNA buffer. Total RNA was isolated and assessed for uPAR mRNA. In initial dose–response experiments (n = 4), we did not find any effect of erythromycin or its derivatives (tested at 50–300 μm) on inhibition of uPAR mRNA, whereas both SIS3 and SB-431542 were effective at 1–10 μm (data not shown). Figure 2 shows the results of 12 experiments of induction of uPAR mRNA by MTB H37RvL (10 μm) (Fig. 2A) or PPD (10 μm) (Fig. 2B) and inhibition of TGF signalling by SIS3

(1 and 5 μm) and SB-431542 (1 and 5 μm). Results shown are mean ± SEM experiments. Induction of uPAR mRNA by PPD was lower in every experiment as compared to MTB H37RvL (P < 0.001) (comparison of first panel from Fig. 2A,B). Whereas SIS3 at both doses effectively inhibited uPAR mRNA induced by MTB H37Rv L (P < 0.01 and 0.05, respectively), AZD1208 solubility dmso inhibition of induction of uPAR mRNA by either dose of SB-431542 was more variable and only significant at 5 μm of the inhibitor (P < 0.01). The inhibitory effect of both SIS3 and SB-431542 on PPD-induced uPAR expression was also very variable and only significant at 5 μm of SB-431542 (P < 0.05). At sites of TB, a major determinant of TGF-β activity is the molecular context that allows its bioactivation and signalling.

Studies to date implicate that 10–20% of TGF-βin Liothyronine Sodium situ is in it’s bioactive state [3]. Further, uPAR mRNA levels were significantly elevated in TB involved as compared to TB uninvolved lung lavage from patients with smear negative pulmonary TB (Z. T. Zahra Toossi, Unpublished observations). Collectively, these data are supportive of use of TGF-β signalling inhibitors as adjuncts to antituberculosis therapy. A spectrum of activity of the inhibitors of bioactive TGF-β was found here; whereas the potency of SIS3 was notable, the better studied SB-431542 was less active. None of the macrolides used were effective in inhibition of TGF-β signalling in induction of uPAR mRNA in human MN. This is disappointing because of lack of toxicity of erythromycin and clarythromycin, which are already in clinical use. Recently, blockade of TGF-β signalling by an orally available type I receptor (Alk5/4) inhibitor augmented efficacy of immunogen therapy in a murine model of prostate cancer [14]. In the current work, ALK5 inhibitor SB431542 did not effectively inhibit induction of uPAR expression in human mononuclear phagocytes.

Cell cultures were incubated

at 37° in a humidified atmosphere containing 5% CO2 for 4 hr and then developed by adding acid isopropanol (0·1 ml). Absorbance was measured at 595 nm using the GENios ELISA plate reader running the Magellan reader control and data reduction software (Tecan Austria GmbH, Salzburg, Austria). The abundance and distribution of IgH, Igκ, and TCR-β rearrangements in genomic DNA isolated from splenocytes (IgH and Igκ) or thymocytes (TCR) were analysed by selleck kinase inhibitor semi-quantitative PCR using sense primers specific for a given VH,19 Vκ,20 and TCR-β21 family member and anti-sense primers located 3′ of a given joining segment: JH4,19 Jκ5,22 and Jβ1.6 and Jβ2.7,21 respectively. Briefly, samples for PCR (100 μl) contained 200, 50, 12·5 and 3·125 ng of genomic

DNA (fourfold dilutions), 20 pmol of each primer, 0·2 mm dNTPs, 20 mm Tris–HCl (pH 8·4), 50 mm KCl, 1·5 mm MgCl2, and 2 units Taq polymerase. Samples were subjected to 30 cycles of amplification (94° for 1 min, 60° for 1 min, and 72° for 1·75 min) followed by a final extension (72° for 10 min). A fragment from the CD14 locus was amplified as a DNA loading control.23 The PCR products were fractionated by agarose gel electrophoresis, transferred AZD2014 nmr to ZetaProbe membrane, and probed with 32P-labelled nested oligonucleotides to JH4 (5′-GCAGACTAATCTTGGATATTTGCCCTGAGGGAGCCGGCTGAGAGAAGTTG-3′), Jκ5 (5′-GCTCACGTTCGGTGCTGGGACCAAGCTGGAGCTGAAACGTAAGTAC-3′), Leukocyte receptor tyrosine kinase Jβ1.6 (5′-TTCCTATAATTCGCCCCTCTACTTTGCGGCAGGCACC-3′) and Jβ2.7.21 IgH CDR3 spectrotyping was performed on genomic DNA isolated from spleens of transgenic mice and their non-transgenic littermates using a sense primer specific for a given VH gene family (VHJ558, VH7813, or VHQ52) and a μ enhancer-specific antisense primer, as described elsewhere.24 Briefly, samples for PCR (100 μl) contained 1 μg genomic DNA, 25 pmol of each primer, 0·2 mm dNTPs, 20 mm Tris–HCl (pH 8·4), 50 mm KCl, 1·5 mm

MgCl2, and 2·5 units Taq polymerase. Samples were subjected to an initial denaturation (94° for 2 min), 40 cycles of amplification (94° for 30 seconds, 65° for 25 seconds and 72° for 25 seconds), followed by a final extension (72° for 4 min). Amplification products were subjected to 10 additional cycles of runoff elongation using a radiolabelled nested antisense primer specific for JH4.24 Runoff reaction products were separated on a sequencing gel, subjected to storage phosphor autoradiography using Storm 860 gel and blot imaging system, and line graphs were generated and analysed using the ImageQuaNT software. Total mRNA was isolated from FACS-purified splenic B220lo CD19+ and B220hi CD19+ B cells obtained from WT and dnRAG1 B cells using the Novagen Straight A’s mRNA Isolation System (Darmstadt, Germany) according to the manufacturer’s instructions.

However, this locus exhibited Carfilzomib research buy a D value of 0.43 with an allele number of seven and thus significantly contributed to the genotyping of the O26 isolates. As such, three loci (EH111-8, EH111-11, and EH111-14) were specifically present in O111 but were of a certain level of usefulness for this serogroup because they exhibited moderate D values (0.21, 0.24, and 0.17, respectively). Our results indicate that these four loci can be used for genotyping the O26 and O111 isolates. Figure 1b shows the results of our evaluation of the 18 loci for the isolates belonging to all the three serogroups together. The allele numbers ranged from 3 to 45, and the D values ranged from 0.34 to 0.92. In this analysis, six loci (EH157-12, O157-34, O157-37,

O157-9, EHC-1, and EHC-2) exhibited higher D values than did the other loci. The overall D values were 0.991 (95% CI = 0.989–0.993), 0.988 (95% CI = 0.986–0.990), and 0.986 (95% CI = 0.979–0.993) for the O26,

O111, and O157 isolates, respectively. These values indicate that our system is useful for genotyping EHEC isolates of not only the O157, but also the O26 and O111 serogroups. As the results mentioned above indicated Osimertinib purchase that our expanded MLVA system was useful for genotyping the O26 and O111 isolates, we next carried out cluster analyses of the O26 and O111 isolates by using the new MLVA system. In this analysis, we included the isolates collected during nine O26 outbreaks and three O111 outbreaks, as filipin well as assessing the applicability of our system for detecting outbreak-related strains in these two serogroups. As shown in Figure 3, the isolates

collected during each of the 12 outbreaks formed unique clusters. Isolates from three outbreaks (26OB5, 26OB6, and 111OB3 outbreaks) did not exhibit any repeat copy number variations for all 18 loci. With regard to the other nine outbreaks, variations were observed for some loci in a few isolates obtained during the same outbreak (Table 2). However, in eight of the nine outbreaks, variations were mainly found in the O157-37 and/or EHC-6 loci, both of which are located in large plasmids, such as pO157, suggesting that entire plasmids may have been lost or parts of these plasmids may have been deleted in some strains during the outbreaks or after strain isolation. These results indicate that the MLVA system can be useful for detecting outbreaks of the EHEC strains belonging to the O26 and O111 serogroups. The O26 and O111 isolates were also subjected to cluster analyses based on PFGE profiles (Fig. 4). Each of the outbreaks formed a unique cluster, as shown in Figure 3. The relative positions of the PFGE-based clusters, however, did not always match those of the MLVA-based clusters. For example, the positions of the clusters of 26OB3 and 26OB7 in the PFGE analysis were closely matched; however, their positions were completely different in the MLVA. Moreover, the subtypes within a cluster defined in each method did not completely match.
