Abstract   

    Gross and histopathological details were recorded in different visceral organs of naturally Salmonella affected chicken layers. Livers, intestines and spleens were the most consistently involved. Enlargement, congestion and bronze discolouration were the main gross lesions in liver. Enlargement and congestion were seen in few lungs. In some cases, heart was congested and slightly enlarged. Discoloured and misshaped ova were recorded in the affected ovaries. Congestion, fatty changes and thickening of the capsule were recorded in the liver and spleen, while in other organs various degrees of degenerative and cellular infiltrative changes were recorded.    

Key words: Salmonellosis, layer, gross and histopathological lesions
