pasteurella multocida is an opportunistic pathogen responsible for pneumonia of lambs and goats, respiratory atrophic rhinitis of swine. although the molecular basis of the pathogenicity and host specificity of p. multocida is not well understood, several studies have reported that a number of proteins are correlated with the pathogenic mechanisms. adhesins have a crucial role in mediating colo...

 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...

The appearance of resistance to many first-line antimicrobial agents presents a critical challenge to the successful treatment of bacterial infections. Antimicrobial resistant bacteria and resistance genes are globally distributed, but significant variations in prevalence have been observed in different geographical regions. This article discusses possible relationships between socioeconomic an...

Six clinically isolated strains of Serratia marcescens were tested for their drug resistance. All showed fairly high resistance to many antimicrobial agents tested including norfloxacin, streptomycin, ampicillin, erythromycin, tetracycline, chloramphenicol, and antimicrobial dyes. Using the drug-hypersensitive strain of Escherichia coli KAM32 as the host, we cloned the genes responsible for mul...

Background: Salmonella is the most important source of food-borne infections around the world. Human salmonellosis is also found in fresh fruit and vegetable salads. Objective: to investigate detection of Salmonella spp.,  in Hamburger, Vegetable salads and Cream-filled pastries from factories, supermarkets, restaurants and local confectionery, Mazandaran, Iran, as well as, to assess their pat...

background: acute infectious diarrhea is one of the most important causes of morbidity and mortality worldwide. objectives: the objective of this study was to characterize antimicrobial resistant diarrheagenic escherichia coli strains isolated from diarrheic children in tehran, ir iran. patients and methods: in total, 550 stool samples from diarrheic pediatric patients, aged less than 60 months...

Molecular methods that enable the detection of antimicrobial resistance determinants are critical surveillance tools that are necessary to aid in curbing the spread of antibiotic resistance. In this study, we describe the use of the Antimicrobial Resistance Determinant Microarray (ARDM) that targets 239 unique genes that confer resistance to 12 classes of antimicrobial compounds, quaternary ami...
