Detection of the eaeA Gene in Escherichia coli Isolated from Broiler Chickens by Polymerase Chain Reaction
The aim of this study was to isolate Escherichia coli from chickens and to determine the presence of the eaeA gene, a virulence factor detected in Escherichia coli, in the isolates by polymerase chain reaction (PCR). Different chicken organs (lung, liver and spleen) were inoculated onto blood agar and biochemical tests were performed on the suspicious isolates. Escherichiacoliwas isolated from ...

strain with no parC mutations. This is consistent with previous findings that gyrA mutations are necessary for quinolone resistance, whereas parC mutations appear to be complementary, as resistant strains do not carry parC mutations alone. – 6 Some studies further suggest that additional parC mutations facilitate increasing levels of resistance, but our study did not support this. For example, ...
متن کاملMolecular investigation of the prevalence and detection of enterohemorrhagic Escherichia coli isolated from traditional cheese in Iran
Introduction: Shiga toxin-producing Escherichia coli (STEC) strains are one of the main causes of food poisoning and diseases such as hemorrhagic colitis and hemolytic uremic syndrome. Food contamination mainly occurs through food of animal origin such as meat and dairy products. The aim of this study was to investigate prevalence and distribution of virulence genes in Escherichia coli isolate...
متن کاملMolecular typing of fluoroquinolone resistant Escherichia coli isolates from patients undergoing prostate biopsy
Background: Escherichia coli (E. coli) is one of the most important infectious agents in patients undergoing prostate biopsy. It belongs to a large family of gram-negative rods, Enterobacteriaceae. This family includes members of the normal flora of the intestine that are only occasionally pathogenic. Recent considerations of rectal colonization with fluoroquinolone-resistant E. coli shows the ...
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...
