Groups of 20 lambs were vaccinated with parainfluenza virus type 3 (PI3) by the intranasal (I.N.) or intramuscular route (I.M.). Approximately 6 weeks later, vaccinated and nonvaccinated lambs were challenged sequentially with PI3 and Pasteurella haemolytica. At slaughter, 10 to 12 days after challenge, 65% of non-vaccinates and 45% of I.M. vaccinates had pneumonic lesions whereas lesions were not observed in any of the I.N. vaccinates.The whole of the literary matter of the New Zealand Veterinary Journal is copyright Taylor and Francis, Downloading this article signifies agreement with the terms and conditions of electronic access.
