BACKGROUND The emergence of antimicrobial resistant strains of Escherichia coli has raised considerable interest in understanding the diversity and epidemiology of E. coli infections in humans. Virulence factors of E. coli determine the specific infections caused by this microorganism. OBJECTIVES This study aimed to determine the prevalence of eight E. coli virulence factors and their associa...

Colibacillosis caused by avian pathogenic Escherichia coli (APEC) is a leading cause of economic loss to the poultry industry worldwide. The ability of APEC to cause disease is determined by certain virulence markers, some of which are located on pathogenicity islands (PAls). We recently described one such PAI in an APEC O1:K1 strain (APEC-O1). This PAI, termed PAI I(APEC-O1), carries the genes...

A one hundred and twenty specimens (frozen chickens) were gathered from various companies sources at sites in Iraq. the aim of this study to detect virulence gene isolated Ecoli frozen chicken meat shops Iraq investigate distribution antibiotics resistance against papC E coli. The result shows that( n,%) 15, 45 ,33,100, 2,6 , 20, 60.6 26,78.7 % out 33 isolate positive for pap C gene, jutA neuC ...

Escherichia coli samples isolated from female patients with cystitis were characterized with regard to the presence of virulence factors associated with biofilm formation and phylogenetic groupings. Polymerase chain reaction results demonstrated that all the samples were positive for the gene fimH (type 1 fimbriae), 91 for fliC (flagellins), 50 for papC (P fimbriae), 44 for kpsMTII (capsules) a...

The phosphatidylcholine specific transfer protein (PCTP) from bovine liver was used to retailor the molecular species composition of phosphatidylcholine (PC) in the membrane of normal (AA) and sickleable (SS) human erythrocytes. Changes in molecular species composition of PC altered morphology as well as cellular deformability and stability as measured with ektacytometry. In normal cells. repla...

Contamination of drinking-water is a significant concern for public health throughout the world. Microbial hazards make largest contribution to waterborne disease in developed and developing countries. Biofilm-producing bacteria were identified by Congo Red Agar (CRA) method we obtained isolated Aeromonas spp. formed Biofilm. antibiotic resistance screening test number antibiotics on isolates. ...
