title: Two cases of mycobacteriosis in psittacine birds.
abstract: Two cases of mycobacteriosis in individual psittacine birds from two separate small aviaries are described. The lesions consisted of infiltration of organs with large macrophages, containing numerous acidfast organisms. There was no caseation or encapsulation of the lesions. No microbiological studies were conducted as mycobacteriosis was not suspected at the time of necropsy.
