Our understanding of the composition of Escherichia coli populations in wild boars is very limited. In order to obtain insight into the E. coli microflora of wild boars, we studied E. coli isolates from the jejunums, ileums, and colons of 21 wild boars hunted in five geographic locations in Germany. Ten isolates per section were subjected to clonal determination using pulsed-field gel electroph...

OBJECTIVES Urinary tract infection caused by uropathogenic Escherichia coli (UPEC) strains is one of the most important infections in the world. UPEC encode widespread virulence factors closely related with pathogenesis of the bacteria. The purpose of this study was to evaluate the presence of different phenotypic virulence markers in UPEC isolates and determine their correlation with antibioti...

INTRODUCTION AND OBJECTIVE The bacterial strains that cause symptomatic urinary tract infections possess diverse distinctive properties that enable them to overcome the local host defenses. In Escherichia coli, virulence results from the cumulative impact of several virulence factors, which can vary according to the patient populations. Hence, a study was undertaken to assess the prevalence of ...

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...

conclusions s. aureus can easily contaminate the chicken nugget and this contamination is usually associated with significant presences of virulence genes. consumption of these nuggets certainly is associated with gastrointestinal diseases. therefore, some food safety and quality standards should be applied and performed in most of the iranian food units to control growth of s. aureus and its v...

Teixeira) The aim of this work was to characterize Enterococcus spp. isolated from Alheira, Chouriça de Vinhais and Salpicão de Vinhais, fermented meat products produced in the North of Portugal, concerning their potential pathogenicity. One hundred and eighty two isolates (76 identified as Enterococcus...

In this study, a number of 85 Staphylococcus aureus isolates were collected from various clinical sources including diabetic foot, burns, urine, wound, abcesses, boils, nasal discharge and vaginal smear from 135 inpatients at different Mansoura hospitals, Dakahlia governorate, Egypt. Isolates were phenotypically investigated for some virulence factors (biofilm, lipase, protease, staphylokinase ...

ABSTRACT Sixty Ecuadorian isolates of Phytophthora infestans from potato and 60 isolates from tomato were compared for dilocus allozyme genotype, mitochondrial DNA haplotype, mating type, and specific virulence on 11 potato R-gene differential plants and four tomato cultivars, two of which contained different Ph genes. Restriction fragment length polymorphism (RFLP) fingerprints of subsamples o...

aim: the purpose of this investigation was to determine the oipa and dupa genes of helicobacter pylori isolates from west of iran; chaharmahalo bakhtiyari region and find their relationship with the severity of the gastroduodenal diseases. background: helicobacter pylori is an organism responsible for many gastroduodenal diseases. studies suggest that genetic diversity in h . pylori virulence f...
