Sažetak
Bovine tuberculosis (bTB) is a re-emerging infectious disease in Europe, which causes a classical One Health problem in certain regions of the Continent. European experiences related to the wild boar’s role in the epidemiology of bTB suggest that this species can be a maintenance host of the disease. In south-western Hungary, Mycobacterium caprae infection is known to be endemic in connection with south European bTB infected wild boar populations. Our goal was to carry out surveillance among wild boars inside this region to determine the prevalence and possible risk of the disease. In the study area (9600 ha) three large-scale cattle farms existed and over the previous 10 years bTB outbreaks were confirmed on each. Between 2008 and 2013 we sectioned 791 hunter-harvested wild boars on a hunting ground during evisceration. Of the 267 bacteriologically examined specimens, 36 (13.5%) proved to be infected by M. caprae. In the field we found 233 carcasses with suspect tuberculosis lesions (TBL). TBLs were generally found in the submandibular lymph nodes; while only two carcasses (n = 2; 0.25%) were found with TBL exclusively outside that region. These lesions could not be inspected without incision; on the other hand, generalization appeared to be very rare (n = 2; 0.25%) in the study area. These findings suggest that visual-only game meat inspection is insufficient to find the primary complex of bTB infection in wild boars. Although these localized small lesions are most unlikely to create any notable hazard for game meat consumers, nevertheless this lack in game meat inspection makes the surveillance system incomplete. Our study confirmed that wild boars play a maintenance role as a bTB host in this part of Hungary. However, development of an effective management strategy against bTB needs further investigations by a multidisciplinary research group.
