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.The articles have been scanned in colour with a HP Scanjet 5590; 600dpi.
