Sažetak
During the last few decades, a growing wild boar (Sus scrofa) population and their colonization of suburban and urban areas has been noted across Europe. As wild boars are known potential hosts of several zoonotic pathogens, more frequent interactions with humans and animals may pose a public health concern. The aim of our study was to assess their potential role as reservoirs for leptospirosis in areas with pronounced human activity. A total of 96 wild boar serum samples were collected within health monitoring project in the Medvednica Nature Park over the period of four years (2014–2016 ; 2018). For antibody detection, microscopic agglutination test was performed using an antigen panel of 12 different serovars ; cut-off titre of 1:100 was considered positive. An overall prevalence of 21.88% was determined with variation that was related to year and season of collection. Higher prevalence of leptospirosis was observed in 2014 (30.77%) and 2015 (31.58%) as opposed to 2016 (6.25%) and 2018 (9.09%). Odds ratio indicate 4.44 times higher possibility of infection in 2014 compared to 2018 (CI 95% .893- 22.118), 6.66 compared to 2016 (.787 – 56.405) and 4.6 in 2015 compared to 2018 (.805- 26.454). Seasonally, 20% of seropositive boars were hunted during spring, 13.79% during summer, 42.11% during autumn and 17.86% during the winter season. Higher prevalence (p < 0.05) was found in adults (> 2 y). As opposed to most of the previous studies, we found higher overall seropositivity in females (p < 0.05). However, these variations were not temporally consistent. The distribution of most prevalent serogroups also varied over time with overall domination of serogroup Pomona (38.1%), followed by Javanica, Grippotyphosa (23.81% each) and Australis (9.5%). Our results confirmed that wild boars are a potential source of pathogenic Leptospira spp. Further monitoring of the prevalence of leptospirosis in wild boars, as well as confirmation and clarification of associated risk factors, are needed.
