CHARACTERIZATION OF STAPHYLOCOCCUS SP ISOLATED FROM ARTHRITIC BROILER BREEDER FLOCK WITH ANTIBIOGRAM STUDY OF IDENTIFIED FIELD ISOLATES

Abstract

The study was conducted for characterization of Staphylococcus sp isolated from arthritic broiler breeder flock with antibiogram study of identified field isolates. The study was performed in a breeder flock. The flock consists of 7000 birds of different age groups, name of the breed cobb 500 selected for the study. The sample were collected from the affected birds and shifted aseptically to the Bacteriology laboratory of the department of Microbiology Hajee Mohammed Danesh Science and Technology University. The samples were subjected to clinical, postmortem and microbiological (morphological, cultural and biochemical) examination. The study shows that infection is very high in starter and grower (58.2%) than laying period (16.6%). The staphylococcus sp highly sensitive to different antimicrobial agents such as 100% sensitive to ciprofloxacin, doxycycline, penicillin, gentamicin and 70% sensitive nitrofurantoin 60% azithromicin and resistance to cephradine, ampicillin, amoxicillin sulfomithoxazole X Trimethoprim.
