Streptococcus gallolyticus subsp. pasteurianus septicaemia in goslings

Increased mortality was observed in a group of 2–3-week old goslings. At post mortem examination, gross lesions included congestion and haemorrhages in the viscera. Histopathological lesions included generalised congestion of tissues with multifocal bacterial colonies, an acute septic fibrinoid splenitis, and an acute septic hepatitis, all consistent with acute septicaemia. Gram-stained sections of liver and lung confirmed the presence of Gram-positive bacteria and Streptococcus gallolyticus subsp. pasteurianus (Streptococcus bovis biotype II/2) was isolated in pure growth from two of the goslings, and in mixed growth from a third.
