| Abstract: | SUMMARY The ability of 2 commercial leptospirosis vaccines to prevent renal colonisation with Leptospira interrogans serovar pomona was studied in pigs. Based on bacteriological, pathological and serological findings some degree of protection was found in vaccinates when compared with non-vaccinates after challenge 4, 7 and 12 months after vaccination. However, the degree of protection was insufficient to prevent colonisation and renal leptospirosis in 6 of 10 pigs at 4 months, 7 of 10 pigs at 7 months and 8 of 10 pigs at 12 months. |
