Antibiotic resistance pattern and virulence genes content in avian pathogenic Escherichia coli (APEC) from broiler chickens in Chitwan, Nepal
BACKGROUND Avian pathogenic Escherichia coli (APEC) are causative agent of extraintestinal infections, collectively known as colibacillosis, which results significant losses in poultry industries. The extraintestinal survival of E. coli is facilitated by numerous virulence factors which are coded by virulence genes. This study was conducted to find out the pattern of antibiotic resistance and v...
متن کاملAvian Pathogenic Escherichia coli (APEC) in Palestine: Characterization of Virulence Factors and Antibiotic Resistance Profile
Escherichia coli bacterium is common to many environments and there are over 150 different strains. Avian pathogenic E. coli (APEC) strains cause diseases in birds at various ages. The introduction of such strains to chicken respiratory tract causes invasive infections, collectively known as colibacillosis. It can cause extensive mortality in poultry flocks leading to great economic losses. Rec...
متن کاملVirulence Genes Content and Antimicrobial Resistance in Escherichia coli from Broiler Chickens
A total of 121 E. coli strains were isolated from broiler chickens (96 extraintestinal pathogenic (ExPEC) strains from diseased broiler chickens and 25 avian fecal E. coli (AFEC) from healthy ones). Ten of the isolates (6 from diseased chickens and 4 from healthy birds) were serogrouped and 25 were examined for 4 virulence markers (tsh, papC, colV, and iss genes) as well as for their antimicrob...
متن کاملA study on the presence of some potential virulence genes and quinolone resistance in avian pathogenic Escherichia coli isolated from chickens in Northeast of Iran
Background: Avian pathogenic Escherichia coli (APEC), which is the causative agent of colibacillosis, harbors several putative virulence genes. An important trait of APEC for both poultry and public health is antibiotic resistance. Objectives: In the present study, some potential virulence genes of APECs isolated from Northeast of Iran and their resistance to the quinolones antibiotics were stu...
متن کاملAntibiotic Resistance in Diarrheagenic Escherichia coli Isolated from Broiler Chickens in Pakistan
Background: Diarrheagenic Escherichia coli (DEC) strains are predominant cause of gastrointestinal tract illnesses. The main objective of the study was to determine antibiotic resistance in various types of DEC isolated from chicken broilers farmed in Pakistan. Methods: A total of 200 feces and 200 meat samples from broiler chickens were collected from the slaughtering shops in Southern Punjab...
