Klebsiella pneumonia infection rates have increased dramatically. Molecular typing and virulence analysis are powerful tools that can shed light on Klebsiella pneumonia infections. Whereas 77.7% (28/36) of clinical isolates indicated multidrug resistant (MDR) patterns, 50% (18/36) indicated carpabenem resistance. Gene prevalence for the AcrAB efflux pump (82.14%) was more than that of the mdtK ...

Objective(s): The nosocomial infections by Aspergillus species are associated with constructions and increased dust loads in hospital indoors. Our main object was to find the environmental sources of Aspergillus species causing hospital acquired infections. Materials and Methods: The clinical and environmental samplings were performed during 18 months from spring 2010 to summer 2011 in Imam ed...

OBJECTIVES Acinetobacter baumannii is an emerging opportunistic nosocomial pathogen. Two factors that may enhance persistence in healthcare settings are antimicrobial resistance and biofilm-forming ability. The aim of this work was to determine whether A. baumannii isolates that persist in healthcare settings (endemic), can be differentiated from sporadic isolates based upon their ability to re...


 The aim of this study was ‎the‎ discrimination Salmonella‎‎ isolated from chicken and their feed ‎and drinking water for the epidemiological control salmonellosis. Totally, 289 samples, ‎including 217 cloaca swabs, 46 water, 26 samples were collected five ‎different farms in Karbala governorate, Iraq. Conventional bacteriology tests, API 20E, Vitek 2, serology used bacterial identificati...

Beef and its products are potential vehicles of Escherichia coli O157, the most important serotype implicated in many large outbreaks of diarrheal infection in humans worldwide. There is a need for rapid detection of contaminated food in order to implement appropriate and effective control measures. In this study, repetitive sequence (rep)-PCR, using three different primers, BOXA1R, ERIC2 and (...

Genetic rearrangements within a population of bacteria were analyzed to understand the degree of divergence occurring after experimental evolution. We used 18 replicate populations founded from Ralstonia sp. strain TFD41 that had been propagated for 1,000 generations with 2,4-dichlorophenoxyacetic acid (2,4-D) as the carbon source. Genetic divergence was examined by restriction fragment length ...

The primary goal of this research was to reveal de novo mutations in the liquidators (cleanup personnel) who emigrated to Israel from the Chernobyl disaster area. We used genome fingerprinting simple sequence repeat-anchored polymerase chain reaction (PCR) amplification and random amplified polymorphic DNA PCR (RAPD PCR). The methodology involved a combination of RAPD PCR, polyacrylamide gel el...
