Avian pathogenic Escherichia coli (APEC) induces colibacillosis, an acute and systemic disease, resulting in substantial economic losses the poultry sector. This study aimed to investigate antibiotic resistance pattern associated with frequent virulence gene distribution APEC O78:K80 that may cause pathological alterations chickens. The antibiogram profile showed high erythromycin, chloramphenicol, tetracycline, ampicillin, co-trimoxazole, followed by intermediate ciprofloxacin,...

Many places in District Lahore such as parks, streets and our homes where people keep pigeons captivity are highly contaminated with pigeon feces. The study was conducted for the bacterial parasitic profiling of native pigeons, drooping's might be cause zoonotic contamination. During 200 fecal samples 100 free roaming each were collected examined laboratory. subjected to enrichment culturing on tetrathionate broth (TTB) Brilliant Green Agar plates isolation Salmonella spp. because its...
