Seroprevalence of Aujeszky’'s disease in pigs in Poland in the years 2001-2004
The evaluation of the seroprevalence of Aujeszky'’s disease (AD) in Poland and the infection rate of the pig population in our country are basic requirements for implementing an AD eradication program. The aim of the presented study was to evaluate the AD seroprevalence in the Polish pig population during the years 2001-2004. In the above-mentioned period a total of 47 445 swine serum samples coming from all 16 voievodships were tested. Among them, 10 559 samples were tested in 2001, 11 974 in 2002, 11 027 samples in 2003 and 13 885 samples in 2004. In 2001 the mean percentage of seropositive pigs was 1.23% and such animals were found in 62.5% of the tested voievodships. In 2002 seropositive animals were found in 50% of the tested voievodships, and the mean percentage of seropositive pigs was 0.95%. In the year 2003 the mean percentage of positive seroreagents was 0’77% and they were found in 37.5% of the tested voievodships. In 2004 the percentage of AD positive voievodships was 50%, and the mean percentage of seropositive pigs was 0.65%. The results presented above demonstrate that the mean percentage of seropositive pigs during the period of 2001-2004 was at the rather low level of 0.88%. However, the percentage of voievodships where seropositive pigs have been found was quite high and amounted to 87.5%. This result indicates the urgent need to undertake an AD eradication program in Poland.
