Antibioticsensitivityof staphylococci isolated from rabbits

Staphylococcus aureus is by far the most frequently isolated microorganism in different animals. In rabbits, this bacterium causes important economic loss associated with several lesions, such as septicemia, pododermatitis, multisystemicabscessation andmastitis.Pododermatitis is a widespread disease of rabbits, which is one of the main reason for the culling of commercial rabbits.The present study aimed to determine the distribution of Staphylococcifrom breeding rabbits with pododermatitis and healthy rabbits of different ages. For this purpose35 samples were collected and examined for the presence of Staphylococcus species by conventionalmethods.The species identify a total of 22 strains of staphylococci was determinedby biochemical method. Sensitivity of staphylococcal strains belonging to different species was studied with respect to antibiotics from different classes by disk diffusion method.3 S. aureus and 12 strains of coagulase -negative staphylococci (CNS)were isolated from diseasedrabbits.CNS included S. xylosus(n=5), S. gallinarum(n=5), S. sapro-phyticus(n=2). Two isolates of S. gallinarum, 2 of S. saprophyticusand single strains ofS. xylosus, S. cohniiand S. simulanswere isolated from healthy animals. The investigated isolates of staphylococci revealed high sensitivity to most of the tested antibiotics. Penicillins, macrolides, lincosamides and cephalosporins of II and III generations were less active against tested isolates.The prevalence of multiple drug resistance in this study was 59% (13/22). Among them 1 S. aureus and 7 strains of CNS were identified.
