ObjectiveTo identify the first cases of cholera in Huainan,0139 epidemic causes and biological properties. MethodsConventional methods of serological and bacteriological methods of the strains were identified by polymerase chain reaction (PCR) to detect cholera virulence genes, susceptibility testing modified KB.Results1 ,was isolated and serum agglutination results,2 patients were all positive stool samples,6 were in close contact with all the negative rectal swab;turtle pond-like 18,5 were positive;turtle egg in battle were like 9,2 were positive ; turtle eggs 7, the positive three copies; turtle waste 11, were negative. 2, or more positive culture drug sensitivity test of the pioneer B, doxycycline resistant; to ampicillin, tetracycline in sensitive;on norfloxacin, gentamicin, ciprofloxacin sensitive. 3,or more positive cultures gene DNA PCR test results,cholera toxin(CT) ,toxin coregulated pilus (TCP) all were positive. ConclusionFrom the outbreak of cholera 0139 is water pollution caused by turtle ponds,The trip types of 0139 Vibrio cholera were highly homologous with that isolated from green turtle;the bacteria of the pioneer B, doxycycline resistance and carrying cta, tcpa virulence genes.

Objective To investigate the antibiotic resistance, virulence genes, and sequence types of Enterococcus faecium ( E. faecium) strains isolated from children under 3 years old in Sui county, Henan province. Methods Kirby-Bauer antibiotic testing was performed to analyze the antibiotic sensitivi-ties of E. faecium strains to 15 common antibiotics. PCR analysis was used to detect the virulence genes car-ried by the E. faecium strains. Multilocus sequence typing ( MLST) was performed for the typing of E. faeci-um strains. Results Forty-seven E. faecium strains were isolated from 120 stool samples collected from chil-dren under 3 years old in Sui county, Henan province, of which 95. 7% were antibiotic-resistant strains. Most of the isolated E. faecium strains were resistant to rifampicin, accounting for 91. 5% (43/47) of all isolates, followed by those resistant to erythromycin and tetracycline, which accounted for 68. 1% (32/47). Moreover, high resistance rates to those antibiotics commonly used in clinical treatments of E. faecium infec-tion including β-lactam and aminoglycosides antibiotics were observed. Those strains resistant to more than three kinds of antibiotics belonged to the same clonal complex including 12 strains of clonal complex 17 ( CC17) harboring the virulence gene of hyl. All of the isolated E. faecium strains were susceptible to vanco-mycin, linezolid, chloromycetin and nitrofurantoin. Conclusion The E. faecium strains isolated from chil-dren under 3 years old in Sui county, Henan province were multi-antibiotic resistant. There were drug-resist-ance strains belonging to the CC17 and carrying the virulence gene of hyl.

[Summary] The aim of this study was to examine the association between obstructive sleep apnea-hypopnea syndrome ( OSAHS ) and microalbuminuria in type 2 diabetes mellitus patients. We found that severe OSAHS significantly increases the risk of early renal damage in type 2 diabetes mellitus patients with HbA1C<7% ( lowest oxygen saturation:OR=2. 41, 95% CI 1. 19-8. 08; apnea hyponea index: OR=2. 91, 95% CI 1. 50-9. 11), suggesting that OSAHS may increase the risk for early renal damage in type 2 diabetes mellitus, especially in those with successful control of glucose.
