“…This bacterial species is a common cause of septicaemia in neonatal foals, but is sometimes also found in other types of infections in both foals and adult horses, such as arthritis, bronchitis, pleuritis, pneumonia and peritonitis (BAIN, 1963;BAKER, 1972;GAY and LORDING, 1980;DILL et al, 1982;KOTERBA et al, 1984;BREWER and KOTERBA, 1990;PEREMANS et al 1991;COLLINS et al, 1994). On post mortem examination, lesions caused by these infections are often characteristically fibrinous (BAIN, 1963;GAY and LORDING, 1980). Similarly, fibrinous lesions can also be found in pneumonic pasteurellosis in cattle, associated with Pasteurella haemolytica (REHMTULLA and THOMSON, 1981).…”
