ABSTRACT
Avian mycoplasmosis is one of the major problems facing the poultry industry, all over the world. Mycoplamsa gallisepticum (MG) and Mycoplasma synoviae (MS) are the two most pathogenic avian mycoplasmas. The present study describes the antibiogram pattern of 13 mollicutes including Mycoplamsa gallisepticum (8), Mycoplasma synoviae (1), Mycoplasma gallinarum (3) and Acholeplasma laidlawii (1) against 21 different antibiotics. These mycoplasma strains were retrieved from the Department of Veterinary Public Health and Epidemiology, LUVAS Hisar which were previously isolated from poultry showing respiratory infection and the in vitro single disc diffusion technique was employed using Frey’s agar medium. Mollicutes were found sensitive to amikacin, enrofloxacin, tylosin, spiromycin, chloramphenicol, chlortetracycline and norfloxacin whereas resistant to cloxacillin, nalidixic acid, ceftriaxone, cefotaxime, cefoperazone, and ampicillin. The colistin, lincomycin, levofloxacin, erythromycin,ciprofloxacin, streptomycin, gentamicin and oxytetracycline showed variable results which formed the basis to formulate resistotype pattern of Mycoplasma gallisepticum and M. synoviae the well known pathogens. It has been concluded from this study that frequent surveillance of antibiotic sensitivity against avian mycoplasmosis should be undertaken to adopt a suitable control measure on the poultry farms of Haryana.
