Experimental infections enabled to test susceptibility of the goose and duck to M. avium. After intramuscular implantation of M. avium suspension, local lesions were observed at the spot of puncture in the geese, and miliary tuberculosis of spleen in 35 days, as well as miliary tuberculosis of liver after 69 days. In the ducks, local lesions were found at the spot of puncture in 35 days and miliary tuberculosis of liver and spleen in 69 days. Cultivation demonstrated mycobacteria in various tissues and organs since day 12 after infection. Peroral infection with contaminated feed caused lesions in spleen and intestine in the geese in 106 days, and then in liver and lungs in 133 days. The ducks had lesions in the intestine in 106 days, and in liver and spleen in 133 and 136 days, resp. Cultivation proved sporadic mycobacteria in liver, spleen, lungs and/or bone marrow and brain in both species. No tuberculous lesions were observed in the geese or ducks within 253 days of the experiment after infections by contacts with the TBC fowl. Cultivation demonstrated sporadic mycobacteria in liver, spleen, kidneys, lungs and bone marrow. The goose and the duck are very resistant to M. avium infection. The duck seems to be less susceptible than the duck.
通过实验性感染来测试鹅和鸭对鸟分枝杆菌的易感性。在肌肉注射鸟分枝杆菌悬液后，鹅在穿刺部位出现局部病变，35天后脾脏出现粟粒性结核，69天后肝脏出现粟粒性结核。在鸭中，35天时在穿刺部位发现局部病变，69天时肝脏和脾脏出现粟粒性结核。自感染后第12天起，在各种组织和器官中培养出分枝杆菌。经口感染受污染饲料后，鹅在106天时脾脏和肠道出现病变，133天时肝脏和肺部出现病变。鸭在106天时肠道出现病变，分别在133天和136天时肝脏和脾脏出现病变。培养证明两种禽类的肝脏、脾脏、肺和/或骨髓及脑中均有散在分枝杆菌。在与结核病禽接触感染后253天的实验期间，鹅和鸭均未观察到结核病变。培养显示肝脏、脾脏、肾脏、肺和骨髓中有散在分枝杆菌。鹅和鸭对鸟分枝杆菌感染具有很强的抵抗力。鸭似乎比鹅更不易感。
