Cryptosporial and bacterial co-infection is reported in a budgerigar with clinical manifestations of septicemia and respiratory tract infection. Microscopically large number of round to oval 2-5μm cryptosporidial organisms were found to be lodged on the parabronchial epithelial cells of the respiratory tract. The bacterial colonies were seen around the parabronchial spaces of the lung tissue. I...
