Abstract
A fibrinous polyserositis syndrome due to generalized Escherichia coli infection in pigs was observed in 13 out of 17 systematically monitored herds. The mortality rate was approximately 0.1% among liveborn pigs. The occurrence was usually sporadic but a minor enzootic was observed in one herd. Most of the affected pigs succumbed during first or second week of life but cases were observed throughout the suckling period. The clinical signs included marked depression, anorexia, rough haircoat, laboured respiration and death in two to five days. Predominant gross pathological lesions were signs of septicaemia and a voluminous, gelatinous and fibrinous exudate in the pleural, the pericardial and the peritoneal cavities. Frequently also a firbinous polyarthritis and a fibrinous pneumonia were present. The majority of the isolated invasive E. coli strains were nonhaemolytic. Serologically 11 different E. coli O groups were encountered. O group most frequently represented was 020. None of the examined E. coli strains belonged to the serogroups which frequently are associated with enteropathogenicity in pigs.
