This study determined the mechanisms and patterns of antimicrobial resistance among the isolates obtained from different wards of a teaching hospital in the city of Mashhad in north-east Iran. Between January 2012 and the end of June 2012, 36 isolates of Acinetobacter baumannii were collected from different wards of Ghaem Hospital. Antimicrobial susceptibility testing and epsilometer testing (E...

BACKGROUND The gut of human harbors diverse commensal microbiota performing an array of beneficial role for the hosts. In the present study, the major commensal gut bacteria isolated by culturing methods from 15 children of moderate income families, aged between 10 and 24 months, were studied for their response to different antibiotics, and the molecular basis of drug resistance. RESULTS Of 1...

24 Among Acinetobacter spp., A. baumannii is the most frequently implicated in nosocomial 25 infections, in particular in intensive care units. It was initially thought that multidrug 26 resistance (MDR) in this species was mainly due to horizontal acquisition of resistance genes. 27 However, it has become recently obvious that increased expression of chromosomal genes for 28 efflux systems pla...

Stenotrophomonas maltophilia is an emerging nosocomial pathogen with high resistance to most clinically used antimicrobials. Tigecycline is a potential alternative antimicrobial for S. maltophilia infection treatment, but its resistance mechanism in clinical isolates is not fully elucidated. We investigated the antimicrobial susceptibility of 450 S. maltophilia isolated during 2012–2015 from th...

BACKGROUND Antimicrobial usage is considered the most important factor promoting the emergence, selection and dissemination of antimicrobial-resistant microorganisms in both veterinary and human medicine. The aim of this study was to investigate the prevalence and genetic basis of tetracycline resistance in faecal Escherichia coli isolates from healthy broiler chickens and compare these data wi...

Bacterial agents must be genotypically analyzed for vaccinations, effective control programs, and antimicrobial resistance genes that could transfer from aquaculture settings to terrestrial ecosystems and humans. Therefore, we investigated the prevalence, genotypic characterization, and antimicrobial resistance of Lactococcus garvieae for two years at aquaculture sites throughout Turkey. A tota...

ABSTRACT
 
 This study aimed to conduct the characterization and molecular detection of pathogenicity antibiotic-resistance genes in Vibrio parahaemolyticus, as causative agent vibriosis Pacific white shrimp. The V. parahaemolyticus isolates were collected from shrimp’s hepatopancreas, before biochemical test polymerase chain reaction (PCR) sequencing 16S rRNA gene confirmation. hemol...
