Molecular detection of Babesia capreoli and Babesia venatorum in wild Swedish roe deer, Capreolus capreolus.

ABSTRACT: The epidemiology of the zoonotic tick-transmitted parasite Babesia spp. and its occurrence in wild reservoir hosts in Sweden is unclear. In European deer, several parasite species, including Babesia capreoli and the zoonotic B. venatorum and B. divergens has been reported previously. The European roe deer, Capreolus capreolus, is an important and common part of the indigenous fauna in Europe, as well as an important host for Ixodes ricinus ticks, the vector of several Babesia spp. in Europe. Here, we aimed to investigate the occurrence of Babesia spp. in roe deer in Sweden.Roe deer (n?=?77) were caught and sampled for blood. Babesia spp. was detected with a PCR assay targeting the 18S rRNA gene. The prevalence of Babesia spp. was 52%, and two species were detected; B. capreoli and B. venatorum in 44 and 7.8% of the individuals, respectively. Infection occurred both in summer and winter.We showed that roe deer in Sweden, close to the edge of their northern inland distributional range, are infected with Babesia spp. The occurrence of B. venatorum in roe deer imply that it is established in Sweden and the zoonotic implication of this finding should be regarded to a greater extent in future.

Project description:BackgroundSmall ruminants are important hosts for various tick species and tick-associated organisms, many of which are zoonotic. The aim of the present study was to determine the presence of tick-borne protozoans and bacteria of public health and veterinary significance in goats and wild Siberian roe deer (Capreolus pygargus) from Heilongjiang Province, northeastern China.MethodsThe occurrence of piroplasms, Anaplasma phagocytophilum, A. bovis, A. marginale, A. capra, A. ovis, Ehrlichia spp. and spotted fever group rickettsiae was molecularly investigated and analyzed in 134 goats and 9 free ranging C. pygargus living in close proximity.ResultsPiroplasm DNA was detected in 16 (11.9%) goats and 5 C. pygargus. Sequence analysis of 18S rRNA sequences identified 3 Theileria species (T. luwenshuni, T. capreoli and T. cervi). Four Anaplasma species (A. ovis, A. phagocytophilum, A. bovis and A. capra) were identified in goats and C. pygargus. Anaplasma ovis and A. bovis were detected in 11 (8.2%) and 6 (4.5%) goats, respectively; A. phagocytophilum, A. bovis and A. capra were found in 3, 7 and 3 C. pygargus, respectively. Sequence analysis of 16S rRNA sequences revealed the presence of 5 different genetic variants of A. bovis in goats and C. pygargus, while the analysis of 16S rRNA and gltA sequence data showed that A. capra isolates identified from C. pygargus were closely related to the genotype identified from sheep and Haemaphysalis qinghaiensis, but differed with the genotype from humans. Anaplasma/Theileria mixed infection was observed in 2 (1.5%) goats and 5 C. pygargus, and co-existence involving potential zoonotic organisms (A. phagocytophilum and A. capra) was found in 2 C. pygargus. All samples were negative for A. marginale, Ehrlichia spp. and SFG rickettsiae.ConclusionsThese findings report the tick-borne pathogens in goats and C. pygargus, and a greater diversity of these pathogens were observed in wild animals. Three Theileria (T. luwenshuni, T. capreoli and T. cervi) and four Anaplasma species (A. ovis, A. phagocytophilum, A. bovis and A. capra) with veterinary and medical significance were identified in small domestic and wild ruminants. The contact between wild and domestic animals may increase the potential risk of spread and transmission of tick-borne diseases.
