The natural resistance of cattle to artificial infection with Cowdria ruminantium: the role played by conglutinin.
The conglutinin titres of year-old Bonsmara-cross cattle infected with Cowdria ruminantium were inversely proportional to the severity of the reactions elicited by the infection. There was no correlation, however, between conglutinin levels of 8-month-old calves of the same breed, sex and origin and their susceptibility to heartwater. The role possibly played by conglutinin in the non-specific resistance of cattle to heartwater and in the epidemiology of the disease is discussed.
