Summary

The incidence of enteropathogenicEscherichia coli was higher (33 to 50%) in uncooked chicken sausages than in pork sausages (10 to 43%). The toxigenic isolates in general were of O5 and O89 sero types ofE. coli. The amount of toxin produced varied in raw and boiled sausages as tested by ileal loop and rabbit skin permeability tests. The toxin production was invariably higher at 28°C or 37°C in raw and boiled sausages than at 45°C.

Résumé

L'incidence de souches entéropathogènes d'Escherichia coli était plus élevée (33 à 50%) dans les saucisses de poulet cru que dans les saucisses de porc cru (10 à 43%). Les souches toxigènes d'E. coli isolées étaient en général de type sérologique O5 ou O89. Les tests du loop iléal et de la perméabilité de la peau de lapin ont démontré que la quantité de toxine produite variait dans les saucisses crues et bouillies. La production de toxine était invariablement plus élevée à 28 ou à 37°C qu'à 45°C tant dans les saucisses crues que dans les saucisses bouillies.

Resumen

La incidencia de cepas enteropatógenas deEscherichia coli fue mayor (33 a 50%) en salsichas de pollo crudas que salsichas de cerdo. Los aislados toxinogénicos pertenecían en su mayoría a los serotipos O5 y O89 deE. coli. La variación en la cantidad de toxina producida entre salsichas crudas y hervidas se midió mediante pruebas de permeabilidad en asa ileal y piel de conejo. La producción de toxinas, tanto en salsichas crudas como hervidas, era mayor a 28°C o a 37°C que a 45°C.
