Background & Aims: The efflux pumps play an important role in the development of drug resistance in Klebsiella pneumoniae. The aim of this study was to investigate the antibiotic resistance, and the presence of efflux genes, as well as molecular typing in clinical isolates of Klebsiella pneumoniae. Materials & Methods: In this cross sectional descriptive study, a total of 100 K. pneumoniae iso...
A survey for Arcobacter spp. and Arcobacter butzleri in mechanically separated turkey was conducted during the winter of 1995 and summer and fall of 1996. Arcobacter spp. and A. butzleri were identified by polymerase chain reaction and species-specific oligonucleotide probes. Arcobacter spp. were isolated from 77% (303 out of 395) of the mechanically separated turkey samples with 74% (223 out o...
In this study we used and evaluated three rapid molecular typing methods for the identification of three frequent, clinically significant Salmonella serovars on the basis of the ease, simplicity and reproducibility of the chosen methods. We determined the genetic diversity among several isolates of Salmonella enteritidis, S. typhimiurium and S. virchow, and compared them with other enterobacter...
BACKGROUND Vibrio cholerae causes diarrhoeal disease that afflicts thousands of people annually. V. cholerae is classified on the basis of somatic antigens into serovars or serogroups and there are at least 200 known serogroup. Two serogroups, O1 and O139 have been associated with epidemic diseases. Virulence genes of these bacteria are OmpW, ctxA and tcpA. OBJECTIVES Due to the importance of...
Objective: The study aimed to molecular characterization of Pasteurella multocida local strain using Enterobacterial Repetitive Intergenic Consensus (ERIC), 13 virulence genes and the outer membrane protein (OmpH) gene. Also, development of diagnostic markers by multiplex PCR from investigated genes. Methodology: The ERIC-PCR was used for the detection of the finger print of Pasteurella multoci...
The aim of this study was to investigate the presence and prevalence of bla(TEM), bla(SHV), and bla(CTX-M) and bla(GES)-like genes, responsible for extended spectrum beta-lactamases (ESBLs) production in clinical isolates of Klebsiella pneumoniae collected from a Brazilian tertiary care hospital. Sixty-five ESBL producing K. pneumoniae isolates, collected between 2005 and 2007, were screened by...
