avian coliform septicemia
a disease of chickens, ducklings and young turkeys causing heavy mortality. Characterized at autopsy by fibrinous exudates on the surface of all viscera and E. coli in all organs.
a disease of recently weaned pigs characterized by sudden death or severe diarrhea and caused by pathogenic serotypes of E. coli. The pigs often die of dehydration and toxemia. Those that survive have lost a lot of condition. Called also post-weaning diarrhea.
peracute bovine mastitis caused by E. coli and characterized by minor enlargement and inflammation of the udder, thin serous milk containing small flakes. There is profound shock, the mortality rate is high and the quarter is lost. See also mastitis-metritis-agalactia of sows.
the more severe form of pyometra in bitches and queens, characterized by severe toxemia and a fetid, viscous, red-brown uterine exudate.
