the use of chloramphenicol is prohibited in food producing animals due to its harmful and even potentially fatal side effects in human. in order to screen broiler carcasses for the drug residues, 31 broiler chickens from different farms were sampled. the samples from kidneys were homogenized, extracted using ethyl acetate and dried under n2 flow. the samples were then assayed using enzyme-linke...
Objective: Indiscriminate use of antibiotics in poultry farms increases the chance antibiotic-resistant and ESBL producing bacteria Bangladesh. Therefore, study was undertaken to detect extended-spectrum β-lactamase (ESBL) Escherichia coli (E. coli) chickens. 
 Materials methods: A total 60 cloacal swab samples (20 from commercial layer, 20 broiler, Sonali chickens) were collected Rajshahi...
The current study described the isolation and molecular detection of Mycoplasma gallisepticum (Mg) and Mycoplasma synoviae from tracheal swabs of diseased birds showing signs of respiratory distress in selected commercial (layer and broiler) farms and from yolk and an open air of pens of vaccinated breeder flocks in Sudan. A number of 45 Mycoplasma isolates were recovered from chickens in Khart...
