Abstract:
Recently, rearing of pet birds have increased with the increased socio-economic condition
of the citizen. These pets population may contribute many zoonotic bacteria to public
health. Salmonella spp. and E. coli are considered as the most common zoonoses in the
world, causing important losses to public health. Considering these significances, this
study assessed the occurrence of Salmonella spp. and Escherichia coli in caged Pigeon,
Budgerigar & Lovebird. A total of 45 fecal samples were collected as environmental
sample from these 3 different species of birds from pet shops of Katabon, Dhaka. Twenty
samples from Pigeon (P-1 to P-20), Fifteen samples from Budgerigar (B-1 to B-15) &
Ten samples from Lovebird (L-1 to L-10) were collected. Birds with positive cases of E.
coli were found 22 (48.8%) & positive cases of Salmonella spp. were found 8 (17.7%).
Rest 15 (33.33%) samples were unidentified. The occurrence of E. coli were 7 (35%), 11
(73.33%) and 4 (40%) in case of pigeon, budgerigar and lovebird respectively. The
occurrence of Salmonella spp. in pigeon was 40%. No isolates of Salmonella spp. were
found in budgerigar & lovebird. The antibiotic study revealed that all the isolates of E.
coli were 100% sensitive to Ciprofloxacin, Norfloxacin, Amikacin, Azithromycin &
Gentamicin. All the isolates of E. coli were 100% resistant to Tetracyclin, Ampicillin &
Colistin sulphate. All the isolates of Salmonella spp. were 100% susceptible to
Amoxicillin, Amikacin & Gentamicin and showed 100% resistance to Tetracycline,
Trimethoprim & Colistin sulphate. These results analyze that birds that were analyzed
may carry and spread these enterobacteria, and preventive measures for human exposure
should be determined, as these microorganisms are public health concerns.
