Antibiotic Resistance and Biofilm Formation of XXXX in @entity1 and Environmental Samples.

@entity1 @entity797 @entity32799 @entity580
BACKGROUND: Enterococci are opportunistic pathogens and are a major factor in @entity580 . They may contain @entity32799 operon, which upon expression makes them highly prone to biofilm formation on biotic and abiotic surfaces. OBJECTIVES: The aim of the current study was to detect the polymorphism of @entity32799 genes in @entity797 . MATERIALS AND METHODS: Samples were isolated from @entity1 (n = 58) and hospital environments (n = 32) of two hospitals in Tehran, Iran. All enterococcal species were identified by species-specific polymerase chain reaction (PCR); the antibiotic resistance pattern against nine antibiotics was determined. The @entity32799 A, @entity32799 B, @entity32799 C and srt C genes were detected by PCR and the biofilm formation by the isolates was evaluated using the microtiter plate method. The genetic diversity of @entity32799 genes was analyzed by restriction fragment length polymorphism (RFLP). RESULTS: The results indicated that, 86% of @entity1 and 29% of environmental isolates carried @entity32799 genes. The ability of the isolates to strongly attach was 62% and 71% for @entity1 and environmental samples, respectively. The RFLP of the @entity32799 showed no genetic variations amongst the isolates. CONCLUSIONS: The results of the antibiotic resistance and other data suggest that there is a possible common clone of @entity797 , which could rapidly disseminate in @entity1 and the environment.
