This document lists various diseases in poultry and their associated gross lesions and causative organisms. It describes lesions and diseases found in the mouth/esophagus, crop, proventriculus, liver, kidney, body cavity, intestines, legs, testis, and bones. For each organ, it lists common gross lesions and their potential causes, including various bacteria, viruses, deficiencies, and parasites that can infect poultry. The document appears to be part of a course on practical poultry diseases, listing key information on location, lesions, and causative agents.
