Purification and characterization of P fimbriae from an Escherichia coli strain isolated from a septicemic turkey.

Production, Purification and Characterization of Chicken Egg Yolk Monoclonal Antibody Against Colonization factor antigen -1 of Enterotoxigenic Escherichia coli Causing Diarrhea

Enterotoxigenic Escherichia coli (ETEC) causes diarrhea in both humans and animals. The contaminated food and water are the most common vehicles for ETEC infection. The colonization factor antigen (CFA-1) is a fimbriae protein that promotes adherence of the ETEC strain to the epithelium of the small intestine of the host. In this study IgY proteins were produced against the CFA-1 of ETEC in imm...

Identification and Purification of F11 Fimbriae on Avian Pathogenic Escherichia coli

Construction of a Nanobodies Phage Display Library From an Escherichia coli Immunized Dromedary

Background: Diarrhea caused by Escherichia coli is a major cause of morbidity and mortality in young animals. Few treatment options are available, mainly antibiotic therapy increasingly limited by resistance to commonly used drugs.Objectives: The aim of this work was to develop immunotherapy based on the use of camel VHH antibody fragments, or nanobodies,...

Molecular Study of Phase Variation of Type 1 Fimbriae in Uropathogenic Escherichia coli O44 Serotypes during Touching with Solid Surfaces

Background & Aims: Type 1 fimbriae is the most common adhesion factor in urine tract infection. In this Study, presence of virulence genes in isolated strains of uropathogenic E.Coli, O serotyping and molecular detection of phase variation of type 1 fimbriae were assessed during solid surfaces exposure. Methods: Isolated E.coli from urine samples of patients were serotyped by using serologic me...

بررسی فراوانی سروتایپ‌های انتروپاتوژن دارای ژن‌ pap G در اشریشیاکلی جداسازی شده از ادرار و خون بیماران بستری در بیمارستان‌های شهرستان خرم‌آباد

Background and Objective: Escherichia coli (E-coli) is a normal gram negative organism that inhabit the human and animal intestinal tract. Pap G gene has an important role in creating P -fimbriae tip and in producing septicemia and urinary tract infection. The aim of this study was to investigate the presence of pap G gene in EPEC strains isolated from urine and blood. Materials and Metho...
