“…S. cymruensis in this study was found in a spleen sample, which is a possible location for extra‐intestinal Sarcocystis spp. stages, which are increasingly reported in muscle tissue from carnivore definitive hosts (Máca, 2018; Prakas et al., 2019).…”

The aetiology and epidemiology of vector borne apicomplexan Babesia and Hepatozoon and kinetoplastid Leishmania infantum infections in wildlife have not been explored in wide areas of southern Spain. We investigated these infections in 151 wild carnivores, including foxes, badgers, beech martens, hedgehogs, wild cats, Egyptian mongooses, otters, genets and racoons. Overall, Hepatozoon, Babesia and L. infantum infections were detected in 68%, 48% and 23% of the wild animals surveyed, respectively. L. infantuminfected wildlife were more likely to be also infected with the apicomplexan Hepatozoon and Babesia spp. compared to the non-infected counterparts (p < .05). We report for the first time Hepatozoon martis in badgers and wild cats and H. canis in beech martens, and a Babesia sp. in wild cats from Spain. Our results also indicate the widespread distribution of H. canis in foxes (91%) and beech martens (13%), H. martis in beech martens (81%), wild cats (20%) and badgers (13%), H. felis in wild cats (60%), B. vulpes in foxes (64%), Babesia sp. type A closely related to B. vulpes, in badgers (58%) and Babesia sp. in wild cats (20%). Moreover, L. infantum infection was found in foxes (29%), beech martens (13%), badgers (8%) and 1/3 Egyptian mongooses. We also detected Cytauxzoon sp. in a wild cat and the first Sarcocystis sp. in a genet. This study provided evidence of increased risk of L. infantum infection in wildlife animals co-infected with Babesia spp.or Hepatozoon spp. and indicated that these infections are widespread in wild carnivores from Spanish Mediterranean ecosystems.

“…In each set of PCR positive and negative controls, water instead of template DNA were applied. During our previous investigations, the DNA extracted from the individual sarcocysts of S. ratti [41] and S. myodes [32] were used as positive controls. PCR products were visualized using 1.0% agarose gel electrophoresis.…”

“…Sarcocystis sp. Rod1 was placed into one cluster together with the S. myodes and S. ratti described in the rodents from the Baltic States [32,41], and Sarcocystis sp. Rod2 was a sister taxon to the S. lutrae detected in various predatory mammals [72].…”

Small mammals are an important group of wildlife that can transmit pathogens to humans and animals. There is a lack of comprehensive studies on the protozoan parasites of the genus Sarcocystis in agricultural areas. The aim of the current research was to evaluate the prevalence of Sarcocystis spp., and to identify the parasite species found in the skeletal muscles of rodents and insectivores from commercial orchards. A total of 679 muscle samples from small mammals, mainly rodents (n = 674), belonging to eight species were examined. Muscle samples were pooled into groups, then digested, and the presence of the Sarcocystis species was confirmed by molecular methods. The examined parasites were determined in five rodent species, Apodemus agrarius, A. flavicollis, Clethrionomys glareolus, Microtus arvalis, and M. oeconomus. The prevalence of Sarcocystis spp. was low: 2.23% in voles and 0.79% in mice. Based on a sequence comparison of cox1 and 28S rDNA, four species were identified: S. myodes, Sarcocystis cf. strixi, Sarcocystis sp. Rod1, and Sarcocystis sp. Rod2. This is the first report of S. myodes in A. agrarius, A. flavicollis, and M. arvalis. The identified species were most closely related to Sarcocystis spp., and were transmitted by predatory mammals and birds. Future studies are needed to describe the species morphologically, as well as to define the host spectrum and to evaluate their possible pathogenicity.

“…Our dietary research revealed that fish is the main food of raccoon dogs inhabiting the waterside area ( Woo et al, 2022 ) and Eurasian otters inhabiting the estuary area ( Kumari et al, 2019 ) in Korea. In addition, in the feces of leopard cats, genera containing species whose intermediate and/or definitive hosts are small mammals such as rodents and/or birds, e.g., the apicomplexa Eimeria ( Todd and Lepp, 1971 ) and Sarcocystis ( Prakas et al, 2019 ), the nematode and Heterakis ( Smith, 1953 ; Katherine Lynn and Robert Byron, 2019 ), and the platyhelminth Neodiplostomum ( Sanmartin et al, 2004 ), were abundantly detected. Our dietary study revealed that murids and birds are the main prey of leopard cats in the inland areas ( Woo et al, 2023 ).…”
