Received at: 18/8/2013 Accepted: 23/10/2013 A total of 105 cases of broilers were collected from broiler flocks showing high mortality rates in Sharkia Governorate. E. coli was isolated from 84 (80%) cases. A number of 11 different serotypes were identified, of which O114:K90 was the most detected with 17.9% of the total isolates. While O125:K70, O55:K59, O111:K58 and O26:K60 were identified wi...

Aim This study describes the prevalence of Escherichia coli in frozen chicken meat intended for human consumption with emphasis on their virulence determinants through detection of the virulence genes and recognition of the extended-spectrum β-lactamase (ESBL) encoding genes (blaOXA and blaTEM genes). Materials and Methods A total of 120 frozen chicken meat samples were investigated for isola...

in modern medical processes, new antimicrobial drugs are being widely used in order to rapid and essential eradication of resistant bacterial strains. broad-spectrum beta-lactamases are enzymes originated from mutations in the common plasmid genes mediators for beta-lactamases such as tem-1, tem-2, and shv-1 are transferred among bacterial species. the genes coding the production of esbl are of...

This study was conducted to identify the risk factors that are associated with neonatal mortality in lambs and kids in Jordan. The bacterial causes of mortality in lambs and kids were investigated. One hundred sheep and goat flocks were selected randomly from different areas of North Jordan at the beginning of the lambing season. The flocks were visited every other week to collect information a...

BACKGROUND Enteroaggregative Escherichia coli (EAEC) causes diarrhea, malnutrition and poor growth in children. Human breast milk decreases disease-causing bacteria by supplying nutrients and antimicrobial factors such as lysozyme. Goat milk with and without human lysozyme (HLZ) may improve the repair of intestinal barrier function damage induced by EAEC. This work investigates the effect of th...

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 (stx 1/stx 2) was detected in 36 (14.7%) of the 2...

Background & Aims: Type 1 fimbriae is the most common adhesion factor in urine tract infection. In this Study, presence of virulence genes in isolated strains of uropathogenic E.Coli, O serotyping and molecular detection of phase variation of type 1 fimbriae were assessed during solid surfaces exposure. Methods: Isolated E.coli from urine samples of patients were serotyped by using serologic me...
