Sažetak
Leptospirosis is an infectious disease caused by pathogenic spiral bacteria Leptospira spp. that can affect both humans and animals. Despite the fact that Leptospira spp. can infect different reservoirs and consequently make contamination of various habitats, high humidity and stagnant water reservoirs are considered as predominant factors for survival of leptospires in nature. In this study we have analyzed sera samples from 17 wild boars collected at lowland area of Žutica and 27 samples from suburban hilly area of Medvednica Mountain. Detection of specific antibodies were performed by microscopic agglutination test (MAT) and only titres >100 were considered positive. High overall seroprevalence detected at both sites comprehended 35 % of wild boars from Žutica (conf. level 95%, 6.95-10.05) and 46 % of wild boars from Medvednica region (conf. level 95%, 11.05-15.95). From positive samples, only two were positive for just one serovar all others demonstrated cross-reactivity with antigens of other serovars. Titres in samples from Žutica region ranged from 100 to 1000, and from Medvednica region ranged from 100 to 3200. The most frequent presumptive infective serovar at both sites belonged to serogroup Australis that was in Žutica region followed by serogroup Sejroe and in Medvednica region by serogroup Icterohaemorrhagiae and Pomona. Occurrence of different infective serovars could be easily explained by the geographical locations of those two sites. Circulating serovars from the serogroup Australis, Sejroe and Pomona are mainly harbored by mouse like rodents and their presence at different Croatian forest areas is already reported in previous studies. On the other hand, proximity of Medvednica to a large city could be the cause of increased prevalence of serovar Icterohaemorrhagiae that is mainly carried by a rat. In conclusion, high incidence of leptospirosis among wild boars reveals their potential to maintain and spread disease, especially in suburban areas.
