Fungi isolated from Pulmonary Mycosis in chicks in Thailand are Candida albicans, Aspergillus spp. and Mucor spp. Candida albicans was isolated from the infected chicks 3-4 weeks old. These birds were raised in the infected pens which served as the resevoir of the disease. Pulmonary Mucormycosis and Pulmonary Aspergillosis occurred in the chicks 1-10 days old. It was characterized by gasping and breathing by mouth. Death occurred due to physiological obstruction of the air passages in the lungs. One colony of Mucor spp. was isolated from one unused paper box out of 20 boxes. These boxes were used for transportation the newly hatched chicks. The symptom of mouth breathing disappeared when the infected newly-hatched chicks were transferred from the paper boxes into the pen that had more space and more ventilation with the tem- perature control. Usually the symptom of mouth breathing of newly-hatched chicks occurred in the raining season when the humidity was very high.
