Sažetak
Leptospirosis in swine is characterised by impaired fertility, neonatal deaths, abortions and weak piglets. According to annual orders issued by Ministry of Agriculture for years 2008, 2009 and 2010, all boars used for natural breeding and production of semen for artificial insemination must be serologically tested for leptospirosis twice each year. In addition, all cases of abortion in swine must be reported and blood of each animal serologically tested for leptospirosis. During 2008, 2009 and 2010 more than 20000 swine blood samples were tested for leptospirosis. All samples were tested by microscopic agglutination test (MAT) for the presence of 11 leptospiral antigens: serovar (sv.) Icterohaemorrhagiae, sv. Ballum, sv. Australis, sv. Pomona, sv. Grippotyphosa, sv. Sejroe, sv. Saxkoebing, sv. Tarassovi, sv. Canicola, sv. Bataviae and sv. Hardjo. Initial dilution of blood samples for MAT testing was 1:100. In 2008, 10501 blood samples were tested for leptospirosis and 990 (9, 43%) were positive with at least one serovar. In 2009, out of 6387 tested blood samples, 468 (7, 33%) were positive, while in 2010, 3966 blood samples were tested and 236 (5, 95%) were positive for leptospirosis. In 2008 Međimurje county had the highest prevalence of positive blood samples (25%). In Sisak-Moslavina there were 16, 47% positive samples, in Krapina-Zagorje 13, 51% and in Varaždin county 12, 5% positive samples. In 2009 the higest prevalence of positive blood samples was in Osijek-Baranja county (12, 27%), followed by Zagreb county (9, 33%), Brod-Posavina county (8, 91%) and Međimurje county (6, 73%). Like in 2008, in 2010 the highest percentage of positive blood samples was found in Međimurje county (10, 13%). Koprivnica-Križevci county had 9, 66%, Brod-Posavina county 8, 48% and Zagreb county 8, 39% positive blood samples. During monitored period only few blood samples from coastal counties in Croatia were tested for leptospirosis and none of them was positive. In 2008 and 2009 the most frequent serovar was sv. Australis (55, 71%/2008 and 39, 66%/2009) followed by serovars Pomona (17, 26%/2008 and 21, 55%/2009), Icterohaemorrhagiae (10, 70%/2008 and 17, 24%/2009), Sejroe (7, 49%/2008 and 8, 74%/2009) or Grippotyphosa (4, 42%/2008 and 8, 99%/2009) and Hardjo (2, 28%/2008 and 3, 08%/2009). Sv. Pomona was the most frequent serovar in 2010 (28, 9%) followed by serovars Icterohaemorrhagiae (23, 02%), Sejroe (18, 16%), Australis (10, 49%), Grippotyphosa (10, 23%) and Hardjo (7, 93%). In 2008, 2009 and 2010 serovars Canicola and Saxkoebing were sporadically found, while in 2008 there were also a few samples positive with serovars Bataviae, Tarassovi and Ballum. Regarding the seroprevalence, leptospirosis in swine is common disease in continental counties in Croatia. Although leptospirosis in swine is in decrease, the risk of spreading it to other animals and humans still exists thus causing substantial economic losses in pig farming and threat to human health.
