aureus protein A (spa) typing. They were examined for their antimicrobial susceptibilities. Results: Among the 60 isolates, ST239 was identified most frequently (34 isolates; 58%), followed by ST5 (20 isolates; 34%). Nine spa types were obtained and 4 PFGE strain families (A, B, C, and D) were resolved. Spa type t030, which corresponded to PFGE genotypes A1, A3, and A4, constituted 45% (27/60) of all isolates; spa type t037, which corresponded to PFGE type A2, accounted for 13% (8/60) of all isolates. These 2 spa genotypes belonged to ST239 and
carried SCCmec type III. Isolates genotyped as spa type t002 comprised 27% (16/60) of the study set and included isolates typed as PFGE B1 and B2, ST5, and SCCmec II. Most of MRSA Ispinesib isolates belonging to ST239 were susceptible to trimethoprim-sulfamethoxazole. The minimum inhibitory concentration (MIC 50) of vancomycin among MRSA isolates belonging to ST5 (2 mg/l) was higher than that for other isolates (1 mg/l). Conclusions: These data document 2 major epidemic MRSA clones in Shenyang, China: ST239-MRSA-SCCmec type III-t037/t030 and ST5-MRSA-SCCmec type II-t002.”
“Background: We present here the first application of 2-photon excited fluorescence detection (TPX) technology for the direct
screening of clinical colonization samples for methicillin-resistant Staphylococcus aureus (MRSA). Methods: A total of 125 samples from 14 patients with previously identified MRSA carriage and 16 controls from low-prevalence settings were examined. Results: The results were compared to those obtained by both standard phenotypic and molecular methods. Givinostat In identifying MRSA carriers, i.e. persons with at least 1 MRSA positive colonization Salubrinal molecular weight sample by standard methods, the sensitivity of the TPX technique was 100%, the specificity 78%, the positive predictive value 75%, and the negative predictive value 100%. The TPX assay sensitivity per colonization sample was 89%, the specificity 93%, the positive predictive value 84%, and the negative predictive value 95%. The median time for
a true-positive test result was 3 h and 26 min; negative test results are available after 13 h. The assay capacity was 48 samples per test run. Conclusions: The TPX MRSA technique could provide early preliminary results for clinicians, while simultaneously functioning as a selective enrichment step for further conventional testing. Costs and workload associated with hospital infection control can be reduced using this high-throughput, point-of-care compatible methodology.”
“Background: Helicobacter pylori infects more than half of the world’s population. The aim of this study was to quantify the association between H. pylori infection and the risk of diabetes mellitus and diabetic nephropathy, and to detect at which stage the infection might have higher pathogenicity in the disease-free status-diabetes mellitus-diabetic nephropathy process.
