摘要

Around 200 hen eggs and 100 duck eggs were considered for isolation of pathogenic staphylococci strains. For the same, a total of 300 egg yolk samples and 200 egg shell samples were taken and there were only 53 (out of 500, i.e. 10.6%) staphylococci isolated after directincubation on 10% sail agar, after primary enrichment of the samples. Egg shell samples yielded 48(24%) and egg yolk samples produced 5 (1.7%) staphylococci isolates. Among these only 11 (20.75%) were positive for coagulase test. When tested for the production of haemolysins, 9 (81.8%) were detected to be haemoiytic while rest 2 (18.2%) found to be negative. Among the haemolytic ones, 2 (18.2%) produced a haemolysin, 3 (27.3%) produced p haemolysin, 2 (18.2%) S, 1 (9.1%) each for alpha- beta and delta-alpha haemolysins, Antibiogram study revealed ciprofloxacin (100%) to be the most sensitive drug followed by cephalexin (90.91%), gentamicin (81.82%), streptomycin (72.73%), ampicillin (63.64%), amoxicillin, doxycyciine (each 54.55%) and cloxacillin, chloramphenicol (each 45,55%), etc. But the drags namely naiidixic acid, tetracycline (each 72.73%) topped the list of resistant drags followed by penicillin G(63.64%), cloxacillin (36.36%), etc, probably due to transmissible drug resistance.
