Clostridium septicum infection causing 5.0 to 5.2% mortality is reported for the first time in the literature from six-week-old growing geese in three flocks comprising 5,200, 5,500 and 5,900 geese, respectively. The affected birds exhibited weakness, uncoordinated movement, ataxia and, frequently, oblique position of the head and neck (torticollis) as well as signs indicative of dysequilibrium. The affected birds died within 18-24 h. Gross pathological examination revealed anaemia, hepatitis with map-like necroses of irregular outline (Fig. 1), acute enteritis, pulmonary oedema and cardiac dilatation. Light and electron-microscopic examination showed that the sinusoids of the liver were markedly dilated (Fig. 2) and filled with serous exudate and gas (Figs 2 and 3), and the hepatocytes surrounding them exhibited severe oedema (Fig. 4). Among the hepatocytes, ciliated bacteria 7-10 mu in length and 1-3 mu in width, bounded by a well-defined cell wall and often showing signs of spore formation were observed (Figs 5 and 6). By bacteriological examination the pathogen was isolated, its properties were studied, and the clinical entity of malignant oedema was experimentally reproduced by intramuscular injection of guinea-pigs and rabbits. The applied antibiotic (oxytetracycline) and furazolidone therapy proved effective.

Excessive unexplained mortality was observed in flocks of double-crested cormorants located at Snake Island in Green Bay, Michigan, in June 1992. Clinical signs included weakness, lethargy, diarrhea, respiratory distress, paralysis of the wings and legs, torticollis, and incoordination. The most significant and consistent gross lesions included edema of the eyelids and periocular tissues, pulmonary edema and congestion, marked splenomegaly, hepatic necrosis, and scattered hemorrhages in visceral organs. Histologically, the principal alterations were severe lymphocytic meningoencephalitis and myelitis, as well as splenic lymphoid necrosis with hemorrhage. A type 1 paramyxovirus was isolated from the affected birds and characterized as a velogenic neurotropic strain of Newcastle disease virus. Since the infection occurred in free-living migratory birds, there exists the potential for spread of the virus over a large area, thus posing a hazard to domestic poultry.
