This in the first report on the diagnosis of anatipestifer disease (caused by Pasteurella anatipestifer) in Hungary in young geese. The disease was studied in four two to three weeks old goose flocks with 2500 to 5000 birds each. The disease was always fatal within one to three days. Morbidity and mortality varied between 2 to 5%. The clinical features were anorexia, difficult movement and nervous symptoms in each flock (retromovement, torticollis, lateral or retropulsion, recumbence, struggling, Fig. 1). The pathological investigations revealed fine, almost not visible fibrin flakes, less frequently fibrin films on the wall of pericardium, air sacks and casually on the serosa of abdominal organs, intestinal catarrh, and besides, in some animals serofibrinous inflammation of the tarsal joint. The histological investigations revealed sero-fibrinous inflammation in the cerebral and spinal meninges and a similar ventricular inflammation (Figs 2 to 6). Pasteurella anatipestifer was isolated on blood agar in the presence of increased CO2 tension from the cavity of ventriculi, meninges and pericardium during the bacteriological investigation. The disease was reproduced by i. p. infection (Tables 3 and 4). Differential diagnosis of Derzsy's disease, mycoplasmosis, chlamydiosis and other bacterial infections (E. coli, salmonellae), as well as pneumo-, air sack and cerebral mycosis have been detailed (Table 1). In case of the mentioned diseases, data were collected by bacteriological investigations on the incidence of P. anatipestifer intercurrent infection (Table 2).
