Phenotypic and genotypic characterization of antimicrobial susceptibility of avian pathogenic Escherichia coli isolated from broiler chickens
Aim Avian pathogenic Escherichia coli (APEC) is pathogenic strains of E. coli that are responsible for one of the most common bacterial diseases affecting poultry worldwide. This study was designed to determine the occurrence, antibiotic resistance profile, and antibiotic resistance genes of E. coli isolated from diseased and freshly dead broilers. Materials and Methods In that context, a tot...
متن کاملVirulence factors and clonal relationships among Escherichia coli strains isolated from broiler chickens with cellulitis.
In this study, we compared Escherichia coli isolates from chickens with avian cellulitis with those from feces of healthy chickens. Cellulitis-derived strains presented phenotypic and genotypic characteristics of greater virulence than did the fecal isolates. Phylogenetic analysis by repetitive extragenic palindromic-PCR showed that, in agreement with their virulence characteristics, the cellul...
متن کاملGenetic Analysis of Avian Orthoavulavirus Type I (AOAV-1) Strains Isolated from Broiler Flocks
Background and aim: Newcastle disease (ND) is one of the most serious diseases among many species of birds and causes devastating effects on the poultry industry. This disease is endemic in Iran and ND outbreaks occur unexpectedly and with high mortality and severe clinical signs. The sequence of the F protein cleavage site is that the major virulence determinant of Newcastle disease virus (NDV...
متن کاملAntimicrobial susceptibility of Clostridium perfringens strains isolated from broiler chickens
Clostridium perfringens is a normal inhabitant of the intestinal tract of chickens as well as a potential pathogen that causes necrotic enteritis and colangio hepatitis. The minimum inhibitory concentration (MIC) of seven different compounds used for therapy, growth promotion or prevention of coccidiosis was determined by agar dilution method for 55 C. perfringens strains isolated from the inte...
متن کاملThe Detection of Fimbrial Pathogenic Genes in E. coli Strains Isolated from Patients with Urinary Tract Infection
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...
