Mycoplasma ovipneumoniae is an important respiratory pathogen of sheep across the world. In the present study nasal swab samples (n=778) were processed and 51isolates of M. ovipneumoniae were identified through biochemical tests and PCR. Difference in the isolation rate among districts (n=12), age groups (n=3), breads (n=6) was assessed. Similarly the isolate rate among healthy (n=513) and respiratory distressed (n=265) sheep were also compared. The results for the district-wise isolation of Mycoplasma ovipneumoniae in sheep showed non-significant variations among districts of Balochistan (2= 1.65, P=0.9990). Statistically significant difference (2 = 7.698, P< 0.02) in the isolation of Mycoplasma ovipneumoniae among various age groups was recorded, while highest isolation was seen in sheep of < 1 year.Statistically highly significant difference (2 = 16.6, P <0.0050) in the isolation of Mycoplasma ovipneumoniae among various breeds of sheep in Balochistan was seen, whereas highest isolation rate (3.70%) was observed in Harnai breed for sheep Furthermore, statistically highly significant difference (Fisher's exact test P≤0.0001) in the isolation of Mycoplasma ovipneumoniae between healthy and respiratory distressed sheep breeds in Balochistan was found.
