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...

OBJECTIVES To characterise the genetic and serological diversity of pathogenic Escherichia coli, we tested 111 E coli strains isolated from diarrhoeal patients in Korea between 2003 and 2006. METHODS The isolates were tested through polymerase chain reaction (PCR) and slide agglutination method for the detection of virulence genes and serotypes, respectively. To compare the expression of Shig...

BACKGROUND In 2008, children playing on a soccer field in Colorado were sickened with a strain of Shiga toxin-producing Escherichia coli (STEC) O157:H7, which was ultimately linked to feces from wild Rocky Mountain elk. We addressed whether wild cervids were a potential source of STEC infections in humans and whether STEC was ubiquitous throughout wild cervid populations in Colorado. METHODOL...

BACKGROUND AND OBJECTIVE Diarrheal disease is still a major health problem, especially in developing countries, where it is considered as one of the leading causes of morbidity and mortality especially in children. Studies showed that Diarrheagenic E. coli (DEC) such as STES and EPEC strains are among the most prevalent causative agents in acute diarrhea, particularly in children. Aim of the pr...

In this study, we attempted to isolate Escherichia coli from healthy adults in Ho Chi Minh City, Vietnam, and characterized its antimicrobial resistance profile, extended-spectrum β-lactamase (ESBL) genotype, phylogenetic grouping and virulence gene profile. A total of 103 E. coli isolates were obtained, and most of them were antimicrobial resistant such to streptomycin (80.6%), tetracycline (6...

A stochastic model for estimating the ratio between a fecal indicator and a pathogen based on left-censored data, which includes a substantially high number of non-detects, was constructed. River water samples were taken for 16 months at six points in a river watershed, and conventional fecal indicators (total coliforms and general Escherichia coli), genetic markers (Bacteroides spp.), and viru...

The aim of the current study was to determine the virulence factors, serogroups, and antibiotic resistance properties of Shiga toxin-producing Escherichia coli isolated from chicken meat samples. A total of 422 chicken meat samples were collected from 5 townships of Iran. Specimens were immediately transferred to the laboratory in a cooler with an ice pack. Samples were cultured, and the positi...

background infectious diarrhoeal diseases cause major problems throughout the world and are responsible for considerable morbidity and mortality. enteropathogenic escherichia coli (epec) may cause infantile diarrhoea among children in developing countries. objectives the aim of this study was to define the prevalence of epec strains in raw milk samples. materials and methods raw milk samples co...
