background: integrons are mobile genetic elements able to obtain the antibiotic resistance gene cassettes. the prevalence of integrons in the enterobacteriaceae family has been varied and played an important role in the development of the drug resistant bacteria. the present study aimed to investigate the contribution of class 2 and 3 integrons in drug resistant diarrheagenic escherichia coli s...

A total of 385 urine specimens from suspected urinary tract infections were subjected to bacteriological analysis and susceptibility testing at a major university hospital laboratory in Tehran. A battery of eight beta-Iactam antibiotics, commonly prescribed in Iran, and three third-generation cephalosporins (ceftazidime, ceftriaxone and ceftizoxime) that are usually reserved for limited us...

background: the emergence and spread of chloroquine resistant plasmodium falciparum in the world stimulated some investigators to consider different aspects of chloroquine resistance in human and rodent plasmodia . using animal plasmo­dia , particularly primate and rodent plasmodia can be useful model for human plasmodia studies. in this study we have tried to consider and compare the sequence ...

cage birds like canaries can potentially harbor human pathogens and contribute to transmission and spread of drug resistant infectious agents to human. considering many people's interests to keep canaries, present study was conducted in canaries from yazd to investigate the beta-lactam antibiotics resistant escherichia coli. 109 e. coli isolates from canary faeces in yazd were evaluated to...

introduction: resistance of pathogenic organisms to countenance antibiotics has become a worldwide problem with serious consequences on the treatment of infectious diseases. the aim of this study was to evaluate antibiotic resistance and also the detection of transferred antibiotic resistance by plasmid in clinical proteus isolates. materials and methods: a total of 250 urine samples were colle...
