The prevalence of specific agglutinins in sera of sows vaccinated against leptospirosis


, : The prevalence of specific agglutinins in sera of sows vaccinated against leptospirosis. Medycyna Weterynaryjna 41(4): 195-198

The studies have been performed in one farm free of leptospirosis, in one farm in the course of leptospirosis eradication and in four farms with leptospirosis. Blood for serological examinations was taken from chosen sows before and then after 2, 4, 6 and 12 weeks and 6 months after Suileptovac T vaccination. Micrscope-agglutination test was performed using live cultures of 5 the most prevalent serotypes of Leptospires. It was found that vaccination stimulates agglutinins against Leptospira tarassovi. In a farm free of leptospirosis and in a farm in the course of leptospirosis eradication dominated low titres (1:100-1:200) which disappeared after 12 weeks since the vaccination. In leptospirous farms where high exposition to leptospirosis exists post-vaccination titres of antibodies increased faster and persisted longer. Persisting low titres (1:100 and 1:200) after six months since the first vaccination was noted in 19.5% of animals and after revaccination of 10.8% of sows, 28 (77.8%) out of 36 sows vaccinated with persisting for a long time titres aborted due to leptospirosis. This fact and disappearance of positive titres in all sows from farms free of leptospirosis enables to conclude that persisted post-vaccination titres of antibodies reflect natural infection, and therefore reactors should be eliminated from breeding.

After inoculation of 'Suileptovac T' vaccine, the titres of agglutinins to serovar tarassovi reached 1:100 or 1:200 in a herd free from leptospirosis, and persisted for 3 months. In four infected herds antibodies appeared quicker and las...
