Abstract
A total of 33 204 birds at different age groups were investigated for salmonella infection. The morbidity and mortality rate due to salmonellosis among the birds was 4.90 and 1.83 respectively. The mortality rate was highest (68.53) in the early age groups (0.3 months). It decreased with age and reduced to 0.25 in the twelve months and above age groups. The high breed were more susceptible compared to the exotic and local breed when mortality rate was found to be 24.00 in Starcross and Lohman brown breeds. The mortality rate due to salmonella infection was 63.43 during the monsoon (June to September) 21.25 in winter (October to January) and 15.32 in summer (February to May). Salmonella pullorum and S. gallinarum were isolated identified and partially characterised on the basis of morphological cultural biochemical and serological tests. The pathogenicity of the isolated organisms was determined by infecting chicks before clinical sign and post-mortem findings were observed. The brilliant green agar was found to be most suitable compared to other media from where the highest number of organisms were isolated (50). Liver and bone marrow (50) were the most suitable samples compared to spleen and heart (40 and 48).
