abstract bachground and objectives: the ability of adherence to the surface of host cell is very critical in the colonization of microbial pathogens. it has been revealed that e. coli strains that infect urinary tracts have different fimbrea such as i, s, fic, dr, and fimbrial adhesions. material and methods: in this study, 363 urine samples were obtained from patients with urinary tract infect...

INTRODUCTION Escherichia coli (E. coli) is the most common cause of urinary infections in hospitals. The aim of this study was to evaluate the ERIC-PCR method for molecular typing of uropathogenic E. coli strains isolated from hospitalized patients. METHODS In a cross sectional study, 98 E. coli samples were collected from urine samples taken from patients admitted to Baqiyatallah Hospital fr...

ADHESINS OF UROPATHOGENIC ESCHERICHIA COLI AND THEIR ROLE IN THE PATHOGENESIS OF URINARY TRACT INFECTIONS

A retrospective study of antibiotic susceptibility was conducted on data from all uropathogenic Escherichia coli submitted to the MeritCare Clinic-Bemidji, MN and the North Country Regional Hospital-Bemidji, MN during 1990, 1993, and 1996. The proportion of antibiotic resistant strains was generally equal or higher in E. coli isolates from community-acquired infections than with E. coli isolate...

BACKGROUND In order to define the virulence factors between Chinese herb-resistant uropathogenic E. coli and susceptible strains, the UPEC isolates were classified into two groups according to its resistance to Chinese herbs. MATERIALS AND METHODS The susceptibility profile of strains was determined by disk diffusion method. PCR systems were used to detect genes encoding papC, Aer, hly and cn...

Recent work has shown how comparative genomic and microarray analyses can provide insights into the transcriptional state of uropathogenic Escherichia coli (UPEC) during infection. This study will serve as an important platform from which to identify virulence determinants and the principle mechanisms of adaptation to the urinary tract.

Escherichia coli is the major aetiological agent of urinary tract infections (UTI). Like diarrhoeagenic strains of E. coli, uropathogenic isolates possess virulence determinants that distinguish them from commensal strains and allow them to produce the clinical manifestations associated with UTI. Several autotransporter proteins have been associated with the ability of E. coli, and other Gram-n...

Enteroaggregative Escherichia coli (EAEC) are heterogeneous, diarrheagenic E. coli. Of EAEC strains from Nigeria, 10 independent antimicrobial-resistant isolates belonged to the multilocus sequence type 69 clonal complex, to which uropathogenic E. coli clonal group A belongs. This finding suggests a recent common ancestor for these distinct groups of pathogenic E. coli.

Background and Objectives: Recently, the use of probiotics for the treatment of Urinary Tract Infections has become more popular. The use of probiotics in therapy is useful as only a few side effects such as destruction of resistant bacteria or disturbance of the intestinal microbiota have been reported. The aim of this study was to evaluate the probiotic effects of lactic acid bacteria by co-a...

Urinary tract infection (UTI) is one of the most frequently acquired bacterial infections and Escherichia coli accounts for as many as 90% of all UTIs seen among ambulatory populations. Risk factors for UTIs include host behaviors, host characteristics and bacterial characteristics. Sexual activity and contraceptive method are the strongest determinant of a symptomatic UTI episode. The characte...
