Abstract

The authors report the results of pathological examinations carried out on 10 mute swans (Cygnus olor) which succumbed to a H5N1 highly pathogenic avian influenza virus (HPAI) infection during an outbreak in February 2006 in Southern Hungary. The most frequently observed macroscopic lesions included haemorrhages under the epicardium, in the proventricular mucosa, pancreas and sometimes skeletal muscles; focal necrosis in the pancreas and liver; myocardial degeneration; acute mucous enteritis; congestion of the spleen and lung and the accumulation of sero-mucinous exsudate in the body cavity. Histopathological lesions comprised lymphocytic meningo-encephalomyelitis accompanied by gliosis and occasional perivascular haemorrhages; multi-focal myocardial degeneration with lympho-histiocytic infiltration; pancreatitis with focal necrosis; acute desquamative mucous enteritis; lung congestion and oedema; oedema of the tracheal mucosa and in young birds, the atrophy of the bursa of Fabricius as a result of lymphocyte depletion and apoptosis. The observed lesions and the good to moderate body conditions were compatible with findings in acute HPAI infections of other bird species reported in the literature. Skin lesions and lesions typical for infections caused by strains of lower pathogenicity (LPAI) like emaciation or changes in the reproductive and respiratory organs, sinuses and air-sacs were not observed.
