The present study was aimed to evaluate the antimicrobial resistance and the presence of antibiotic resistance genes in Vibrios spp. isolated from seafood. A total of 72 isolates of Vibrio in 6 species including V. parahaemolyticus, V. vulnificus, V. alginolyticus, V. harveyi, V. mimicus and V. cholerae were examined. The results revealed that all isolates were expressing multiple antibiotic r...

Introduction: Dental caries is a significant public health problem which destroys the calcified tissues of the teeth. The frequency of lactobacilli in dental caries is usually high. The objective of this study was to evaluate the incidence of these bacteria in dental caries and to identify the antibiotic resistance patterns of them. Methods: Specimens from dental plaque were collected from 30 p...

background and objectives : pseudomonas aeruginosa is one of the most important gram negative opportunistic bacteria which causes infection among burn patients. resistance to the antibiotics in this group of bacteria is increased due to the activity of extended spectrum β-lactamase (esbls) genes. in the current study, we investigated the prevalence of two genes (blaper-1 & blaoxa10) related β-l...

conclusions antibiotic resistance gene cassettes may be carried on integron or other genetic elements. the purpose of this study was to detect integron or genomic islands involved in antibiotic resistance profile of the isolates of h. influenzae collected in this study. results of the twenty isolates, all (100%) were resistant to clindamycin, chloramphenicol and tetracycline, 95% to amoxicillin...

conclusions the most common qnr gene was qnrb, and none of the isolates carried qnra or qepa. the aac (6’)-ib-cr variant was the most prevalent pmqr gene, and it was associated with the prevalence of ciprofloxacin resistance in our esbl-producing isolates. results of the 123 isolates, 103 (83.73%) had one of the five pmqr genes, including 83 (83.83%) of the 99 e. coli strains and 20 (86.95%) of...

resistance gene analog polymorphism (rgap) markers linked to fusarium head blight resistance (fhb) and co-localize with qfhs.ndsu-3bs were identified using f3 plants and f3:5 lines derived from a ‘wangshuibai’ (resistant) / ‘seri82’ (susceptible) cross. the mapping populations were genotyped using 50 degenerate primers designed based on the known r genes. out of the 50 designed primer combinati...

The aim of this study was to determine antibiotic resistance genes, phylogenetic groups and anti-microbial resistance patterns of Escherichia coli isolates from fecal samples of healthy pet cats in Kerman city. Ninety E. coli isolates were recovered from obtained rectal swabs. Antibiotic resistance pattern of the isolates against seven selected antibiotic was determined using ...
