Abstract:
Avian mycoplasmosis is one of the most economically important poultry disease with Mycoplasma gallisepticum and Mycoplasma synoviae being most pathogenic species with worldwide distribution. One hundred Tissue samples comprising of trachea, lungs and air sacs were collected during post mortem of poultry birds and were pooled. For studying different epidemiological factors, a questionnaire was designed for collection information comprising of total birds on farm, number of birds affected, number of birds died, ventilation facilities, number of farms in 1 km² area, agro climatic zone, flock size, distance from nearby road, location of farm etc. The results was statistically analysed by STATA and interpreted. however statistical analysis of the data concluded that the statistical association between these factors and occurrence of Mycoplasma synoviae infection could not be established, which may be due to small sample size as required. For establishment of association of these epidemiological factors, further studies with increased sample size with larger area of study and for a longer period is needed.
