A total of 140 E. coli isolates showed at least one pathogenic determent among the isolated 147 E. coli which were previously collected from clinical and food samples. The other 7 isolates were free from tested virulence genes. Among these 140 isolates, 123 had only the UidA gene, therefore, were classified as non-categorized pathogenic E. coli. The other 17 isolates had at least one characteri...

the objective of this study was to investigate the genotypic characteristics of campylobacter isolates in shiraz, iran. a total of 40 campylobacter isolates including 20 c. jejuni and 20 c. coli were recovered from both cattle and sheep faeces by cultivation methods. the isolates were identified on the basis of polymerase chain reaction (pcr) detection of 16srrna and multiplex pcr to determine ...

Avian pathogenic Escherichia coli (APEC) are the major cause of colibacillosis in poultry production. In this study, a total of 22 E. coli isolated from colibacillosis field cases and 10 avian faecal E. coli (AFEC) were analysed. All strains were characterised phenotypically by susceptibility testing and molecular typing methods such as pulsed-field gel electrophoresis (PFGE) and multi-locus se...

the aim of this study was to investigate the prevalence of stec and epec strains and e. coli o157 serogroup in some equidae and canidae. the fecal samples of 79 animals from 6 different species were evaluated for presence of these strains. all the isolates were tested for virulence genes using multiplex-pcr. non-sorbitol fermenting (nsf) escherichia coli isolates and positive strains for virule...

The present study carried out to evaluate the presence of diarrheagenic Escherichia as causes of diarrhea in young calves in Damietta governorate during period from November 2015 to March 2016. Bacteriological examination was done on a total of (100) fecal samples collected from young diarrhoeic calves of average age of 2 to 21 days to detect the prevalence of E. coli . The samples were grouped...

Urinary tract infection (UTI) during pregnancy is often correlated with complications. As the main objective of this study, we investigated prevalence antimicrobial susceptibility, resistance genes, virulence genes and its relationship different phylogenetic groups among Uropathogenic E. coli strains isolated from pregnant women asymptomatic bacteriuria who referred to Hafez hospital, Shiraz, I...

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...

Enteroaggregative Escherichia coli (EAEC) strains are important diarrheal pathogens. EAEC strains are defined by their characteristic stacked-brick pattern of adherence to epithelial cells but show heterogeneous virulence and have different combinations of adhesin and toxin genes. Pathoadaptive deletions in the lysine decarboxylase (cad) genes have been noted among hypervirulent E. coli subtype...

Objective(s): Escherichia coli strains are common pathogens that can cause urinary tract infections (UTI). This study aimed to assess E. coli phylogroups and virulence types in male and female UTI patients.Materials and Methods: In the present study, 160 uropathogenic E. coli (UPEC) isolates (from both sexes) were assigned to phylogroups/types and some extraintestinal virulence factors were det...
