Abstract
Antibiotics are used as therapeutic as well as prophylactic measures in livestock
industries and pet animal clinics. Use of antibiotics without any restrictions or rationale has led
to serious problems such as drug resistance and hypersensitivity in the human population.
The antibiotic sensitivity pattern of causative organisms isolated from specimens
submitted to the microbiological diagnostic laboratory at the Faculty of Veterinary Medicine
and Animal Science during 12.06.2001 to 12.10.2001 was analyzed with a view to detect any
drug resistance. The bacterial isolates obtained from a total of 37cases showed resistance to a
number of antibiotics tested. The organisms isolated and included in the study were Ecoli,
Streptococcus spp, Klebsiella spp., Pseudomonas spp., Aeromonas spp., Jonesia spp,
Acinetobactor spp, Staphylococcus spp and coliforms. These isolates originated from 24
canine, 8 bovine, 2 feline and 3 wild animal samples. Seventy three percent of the organisms
studied showed resistance to trimethoprim + sulphadiazine combination. A few organisms
(10.8 %) showed resistance to gentamycin. Only one organism (a Staphylococcus spp.) showed
resistance to amoxicillin + clavalunate combination. The other antibiotics for which the
organisms showed resistance were erythromycin (37.8 %), tetracycline (29.7 %), ampicillin
(24.3 %), methicillin (2l.6 %), penicillin (18.9 %), enrofloxacin (13.5 %), mupirocin (2.7 %),
cephradine (2.7 %), streptomycin (2.7 %), diclloxacillin (2.7 %), and norfloxacin (2.7 %). The
results of the study so far show the potential danger of continuous use and abuse of antibiotics.
