AbstractTwo vaccines against pneumonic pasteurellosis were evaluated for efficacy in lambs transported by sea from New Zealand to Saudi Arabia. One vaccine contained whole cell antigens of Pasteurella haemolytica A2 grown under iron restricted conditions. The other contained Pasteurella haemolytica A1 cell surface and leucotoxin antigens. There was no clear evidence of either vaccine leading to a lower pneumonia death or lesion rate than for the control group.
