Abstract: This research work was conducted to study the incidence and gross pathological alteraction produced by Salmonella gallinarium in and surrounding areas of Hyderabad City. For this purpose, all the affected organs were collected and brought to the Laboratory for detailed study. The total number of birds in different farms were 14900 in which the sick birds was 965 (6.47%) the negative birds 765 (5.13%) and positive birds was 200 (1.34%). In all affected organs, the rate of incidence of Salmonella gallinarium was recorded 36.5%. The organs which showed positive reaction towards the Salmonella gallinarium infection were 27 in ovaries (13.5%), Livers 21 (10.5%), Spleens 21 (10.5%) and Kidneys only 4 (2%). The gross pathological changes observed in overies due to Salmonella gallinarium were discoloration 62.3%, enlargement 45.5%, mottling 49.3%, haemorrhages 38.9% nodulating abscesses 19.4% and necrotic foci 25.9%. Liver showed discoloration 62.3%, enlargement 28.9%, mottling 43.4%, heamorrhages 46.3% nodulating abscesses 5.7% and nectrotic foci 10.1%. In similar way, the frequency of gross pathological alteration, which were observed in spleen comprised of enlargement 25.6%, mottling 41.1% Hemorrhages 25.2% nodulating abseccesses 15.3% and nectrotic foci 43.5% in affected birds. The affected kidneys showed discolouration 20.0%, enlargement 6.6% haemorrhages 13.3%, nodulating abscesses 6.6% and necrotic foci 20.0%.
