This study was designed to compare the efficacy of a phytobiotic containing a mixture of essential oils of Oreganum aetheroleum and an antibiotic containing ciprofloxacin as an active principle for the treatment of experimental Escherichia coli (E. coli) infection in broiler chickens. Two-hundred-day-old broiler chickens were divided into 5 equal groups. The 1st group was neither challenged nor...

the present study was conducted to detect the occurrence, serotype, genotype, phylogenetic relationship and antimicrobial resistance pattern of stec from healthy goats of west bengal, india. from the 125 faecal samples collected from healthy goats, 245 isolates were identified as escherichia coli. the e. coli harbouring any gene for shiga toxins (stx1/stx2) was detected in 36 (14.7%) of the 245...

background and objectives: diarrhea is one of the most prevalent diseases in the world, specially in developing countries. one of the most important causative agents of bacterial diarrhea is diarrheagenic escherichia coli (dec) which causes gastroenteritis and this group involving enterotoxigenic e. coli (etec), enteropathogenic e. coli (epec), enteroaggregative e. coli (eaec), enterohemoragic ...

Introduction: Recentlly, resistance to antibiotics has increased and antibiotic-resistant strains producing extended-spectrum beta-lactamases (ESBLs) have emerged among Enterobacteriaceae, mainly in Escherichia coli (E. coli). In this study we aimed to determine phenotypic and genotypic ESBL production in isolated E. coli from women with urinary tract infection (UTI). Materials and Methods: In...

Background: Outer membrane proteins (OMPs) constitute the main structure and about half of the cell wall of Gram-negative bacteria. The OMPs of Escherichia coli (E. coli) play an important role in its drug resistance. Previous studies have shown that the OMPs of E. coli enhance its pathogenic effects by helping the bacterium to evade the immune defense and promote its adsorption to host cells. ...

dear editor: sir, the present public health problem to be concerned is the e. coli outbreak in europe. this problem started in germany and extended widely. the main presentation of e. coli infection is diarrhea. however, the other non-diarrhea symptoms are also mentioned. focusing on eye manifestations, the conjunctivitis is a topic to be focused. indeed, e. coli is confirmed as an important ca...

objective(s) extensive use of quinolones has been associated with raising level of resistance. in the current, we focused on assessing the prevalence of escherichia coli resistance to quinolones and frequency of qnra, qnrb and qnrs in non esbls (extended spectrum beta-lactamases) and esbls producing e. coli with blashv and blatem. materials and methods one hundred and fifty e. coli isolates wer...

introduction: extended spectrum beta-lactamase (esbl) producing escherichia coli generate a major problem for clinical therapeutics and epidemiological study. the incidence of esbl producing strains among clinical isolates has been steadily increasing during the past few years, and remains an important cause of failure of therapy with cephalosporins. the aim of this study was to determine the a...

a variety of probiotic bacteria have been tested to control animal and foodborne pathogenic bacteria in livestock. the mechanism of inhibition of pathogenic bacteria for several of those probiotic microorganisms is mediated by the production of bacteriocins. colicins are probably the group of bacteriocins that have been most thoroughly characterized. colicins are antimicrobial proteins produced...
