Abstract
In this study, seroprevalence of Mycoplasma ovipneumoniae in sheep was determined in Baluchistan, Pakistan. A total of 1047 sera samples from 139 flocks of sheep were tested using indirect haemagglutination assay (IHA). An overall prevalence of M. ovipneumoniae in sheep in Baluchistan was 16.53%. There was no difference in the prevalence among various districts of Baluchistan. The cumulative mean titter (CMT) of 20.32, 50.86 and 50.90 was found in < 1 year, 1-2 year and > 3 years of sheep, respectively. Age of sheep significantly influenced the prevalence being highest in 1-2 years old sheep followed by < 1 and > 3 year old sheep. Likewise, an association was also found between the prevalence and different breeds of sheep highest (70%) in Balochi followed by Harnai and Mengali. The use of IHA was found reproducible, inexpensive and effective tool to monitor the antibodies against M. ovipneumoniae in sheep in Baluchistan. (C) 2013 Friends Science Publishers
