Mycoplasma is of countless fear in avian mycoplasmosis. Their popularity in salable fowl is influencing reasonable victims in Pakistan. The breathing ailment in Balochistan in layer flocks is affecting frugally massive damages. This manuscript describes the serological and polymerase chain reaction established incident of Mycoplasma gallisepticum. Mycoplasmas gallisepticum is branded for affecting respirational illness in layers. The antibodies existence of Mycoplasma gallisepticum is testified here in sera trials (N = 720) in 60 farms with breathing indications in Quetta district, Pakistan. Blood samples were confirmed for Mycoplasma gallisepticum antibody/antigen presence by serum plate agglutination and by enzyme-linked immunosorbant assay. In layer flocks, the Mycoplasma gallisepticum antibodies detected by plate agglutination test and enzyme linked immunosorbant assay were 21% and 35% respectively. The lung tissue samples were processed for isolation of Mycoplasma gallisepticum by culturing in Pleuropneumonia like organism broth and agar and DNA was extracted from cultures by Puregene Gentra kit. Field cultures from lung tissue samples (N=1112) were analysed to identify the Mycoplasma gallisepticum occurrence was 19% yielded a PCR product of 730 bp. An early diagnosis of disease caused by Mycoplasma gallisepticum the serum plate agglutination, enzyme linked immunosorbent assay are helpful and diagnosis should be further confirmed by polymerase chain reaction.
