Background: Campylobacter genus is considered some of the most important agents of bacterial gastroenteritis worldwide. Campylobacter coli (C. coli) is accounted to at least 25% of all Campylobacter related diarrheal diseases moreover, C. coli infections can result in severe complications, such as bacteremia, sepsis, meningitis and spontaneous abortion. Finally, there is evidence that the frequ...

knowledge of antimicrobial resistance patterns in e. coli, the predominant pathogen associated with urinary tract infections (uti) is important as a guide in selecting empirical antimicrobial therapy. methods: to describe the antimicrobial susceptibility of e. coli associated with uti in a major university hospital in tehran (iran), seventy-six clinical isolates of e. coli were studied for susc...

Background: Campylobacter jejuni and Campylobacter coli are zoonotic bacteria which are frequently associated with human diarrhea. Sharing of the cytolethal distending toxin (cdt) genes in Campylobacter is common and is considered species specific. OBJECTIVES: In this study we focused on detecting the presence of cdt gene in C. jejuni and C. coli isolated from broilers, turkeys and quails of Ir...

Background and Aims: Pistacia atlantica is one of the medicinal plants native to Iran and known for its antimicrobial properties. Therefore, the present study aimed to investigate the antibacterial and antifungal effects of the aqueous extract of P. atlantica leaves on clinical isolates of Escherichia coli and Candida albicans in vivo. Materials and Methods: In this descriptive-cross-sectional...

results all 90 campylobacter isolates confirmed by m-pcr were successfully typed using flaa-pcr-rflp. eleven different types were defined according to flaa-typing method and the rflp patterns were located at three separate clusters in rflp image analysis dendrogram. conclusions campylobacter jejuni isolates significantly showed more variety than c. coli isolates. a relatively low genetic divers...

The aim of this study was to investigate the prevalence of virulence and Cytolethal Distending Toxin (CDT) genes in the Campylobacter isolates from intestinal contents and gall bladders of broilers and, to evalute their cytotoxic effects on HeLa cell cultures. These genes play important roles in bacterial adherence to intestinal mucosa, flagella-mediated motility, invasive capability and the ab...
