The present report aims to present the pathomorphological characteristics in the organs and systems during rotavirus enteritis infection in young domestic pigeons, diagnosed for the first time in Bulgaria based upon macro- and microscopic changes in the organs in combination with the method of direct immunofluorescence. This concerns a private flock of domestic pigeons bred in Southern Bulgaria for sporting and racing purposes, the Pazardzhik High-Flying Pigeon breed. The total number of birds was 3,000, 800 having age from 3 weeks to 70 days. The described pathological changes in the various intestinal sections contribute to clarifying the diagnosis and differential diagnosis of rotavirus enteritis in pigeons from other diseases such as: Coccidiosis, Salmonellosis, Trichomoniasis, Hexamitosis, Colibacteriosis, and Cryptosporidiosis as well as other widespread intestinal diseases and viral infections in pigeon flocks.
