Sažetak
Over the period of five years (2002-2007) a total number of 351 wild boar (Sus scrofa) serum samples were collected during the regular hunting procedures. All samples were tested by microscopic agglutination test (MAT) for the presence of specific antibodies (AB) to 12 Leptospira spp. serovars. At different sera dilution (ranging from 100 to 3200) 112 samples (31.9%) were found positive to at least one pathogenic serovar, and AB to nine Leptospira spp. serovars were detected: Australis, Pomona, Tarassovi, Sejroe, Grippotyphosa, Icterohaemorrhagiae, Ballum, Saxkoebing, and Bataviae. In total we recorded 147 positive reactions in which the majority (N=101 ; 68.7%) of them were found positive at basic dilution (BD = 100), whereas 31.3% (N=46) reactions were detected positive at higher dilutions. Most frequently found serovar was Australis (33.3%), followed by serovars Pomona (21.8%) and Tarassovi (14.3%), while serovars Australis and Pomona recorded the highest AB titer (3200) and showed statistical significant frequency in cross-reactions (recorded in 23.8% cases). We found significant differences of AB prevalence in different age groups, with highest distinction between detected positive samples in piglets (21.5%) and adult specimens (50.8%). According to aerial distribution the highest percentage of positive wild boar samples originated from lowland habitats in regions of Posavina (Novska - 46.8%, Kutina - 45.3%) and Slavonija and Baranja (Tikveš - 43.6%). Considering the fact that wild boar population in Croatia is showing constant tendencies to grow, further research is indispensable to clarified wild boar role in transmission of leptospirosis to other wild and domestic species.
