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.
coliform gastroenteritis
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.
coliform mastitis
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.
coliform pyometra
the more severe form of pyometra in bitches and queens, characterized by severe toxemia and a fetid, viscous, red-brown uterine exudate.

La evaluacion microbiologica de la panela evaluada sustenta que este alimento es apto para consumo humano, al estar libre de microorganismos patogenos que puedan causar infecciones o intoxicaciones por su consumo, sin embargo, la presencia de coliformes totales implica falta o escaso manejo de practicas de higiene durante el proceso de elaboracion y almacenamiento del producto, lo cual constituye un aspecto de mejora que debe atenderse.
