Sažetak
Leptospirosis is a re-emerging zoonosis that affects humans, domestic animals and wildlife. Carnivores are at the top of the feeding chain, thus being exposed to pathogens through their preys. Transmission of the leptospires through the food chain by the ingestion of leptospiral-infected carcasses by carnivorous species is already confirmed. The objective of this study was to determine the wolves involvement in epizootiology of wildlife leptospirosis through the investigation of seroprevalence of leptospirosis in Croatian population of grey wolves. Obtained epizootiological data will be subsequently included in a systematic research of wildlife leptospirosis in Croatia. Serum samples of fourteen (seven males and seven females), free-ranging, grey wolves (Canis lupus) were collected in several geographic areas of Croatia during a wolf behaviour, ecology and conservation research. Microscopic agglutination test were preformed using 12 serovars: Grippotyphosa, Sejroe, Australis, Pomona, Canicola, Icterohaemorrhagiae, Tarassovi, Saxkoebing, Ballum, Bataviae, Poi and Hardjo with initial dilution of 1:50. Antibodies to Leptospira spp. were found in low titers (ranging from 1:50 to 1:500) in three out of fourteen samples (3/14 ; 21, 4%). Previously established leptospiral diversity in Croatia was reconfirmed ; in three samples we found antibodies against three different presumptive infective serovars ; Saxkoebing, Australis and Grippotyphosa. All three determined serovars are common in rodents (reservoirs) and in wild cloven hoofed animals that constitute major part of a wolf diet. Further research work is indispensable in order to enlarge the sample size and to clarify the epidemiological importance of wolves in leptospiral transmission and maintenance.
