Abstract
Indirect bacterial agglutination titers to P. haemolytica A1 were determined in serum, thoracic, pericardial or peritoneal fluid from cattle necropsied as part of the Bruce County Beef Project in 1979-1980 and 1980-1981. Antibody titers were also assayed in serum from 84 calves on entry to feedlots in the fall of 1979. Titers on entry were low compared to antibody levels at necropsy. Cattle which died with pneumonia, in particular those dying of fibrinous pneumonia (shipping fever), had lower levels of antibody to P. haemolytica than did those dying of other causes.This publication has 9 references indexed in Scilit:
