“…Previous molecular studies investigated the Sarcocystis species composition of roe deer, yielding four genetically characterized species. Only S. oviformis (Gjerde, 2012;Kolenda et al, 2014) was not found in our study whereas S. capreolicanis (Gjerde, 2012;Prakas & Butkauskas, 2012), S. gracilis (Gjerde, 2012;Kolenda et al, 2014), and S. silva (Gjerde, 2012;Kolenda et al, 2014) were found. This is also the first record of S. bovini, S. grueneri, S. miescheriana, S. taeniata, and S. truncata in this ungulate ( Figure S2a).…”

“…We confirmed S. miescheriana (Kia, Mirhendi, Rezaeian, Zahabiun, & Sharbatkhori, 2011;Prakas & Butkauskas, 2012) but not the zoonotic S. suihominis (Prakas & Butkauskas, 2012) in our sample of wild boar ( Figure S2c). The fact that the supposedly suid-specific species S. miescheriana was also detected in cervids, and that S. miescheriana reads sequenced in this study had a higher intraspecific diversity than all other detected sarcocystis (Table S1), suggests that S. miescheriana sequences deposited in GenBank could potentially derive from more than the one species characterized to date.…”

The recent recolonization of Central Europe by the European gray wolf (Canis lupus) provides an opportunity to study the dynamics of parasite transmission for cases when a definitive host returns after a phase of local extinction. We investigated whether a newly established wolf population increased the prevalence of those parasites in ungulate intermediate hosts representing wolf prey, whether some parasite species are particularly well adapted to wolves, and the potential basis for such adaptations. We recorded Sarcocystis species richness in wolves and Sarcocystis prevalence in ungulates harvested in study sites with and without permanent wolf presence in Germany using microscopy and DNA metabarcoding. Sarcocystis prevalence in red deer (Cervus elaphus) was significantly higher in wolf areas (79.7%) than in control areas (26.3%) but not in roe deer (Capreolus capreolus) (97.2% vs. 90.4%) or wild boar (Sus scrofa) (82.8% vs. 64.9%). Of 11 Sarcocystis species, Sarcocystis taeniata and Sarcocystis grueneri occurred more often in wolves than expected from the Sarcocystis infection patterns of ungulate prey. Both Sarcocystis species showed a higher increase in prevalence in ungulates in wolf areas than other Sarcocystis species, suggesting that they are particularly well adapted to wolves, and are examples of “wolf specialists”. Sarcocystis species richness in wolves was significantly higher in pups than in adults. “Wolf specialists” persisted during wolf maturation. The results of this study demonstrate that (1) predator–prey interactions influence parasite prevalence, if both predator and prey are part of the parasite life cycle, (2) mesopredators do not necessarily replace the apex predator in parasite transmission dynamics for particular parasites of which the apex predator is the definitive host, even if meso‐ and apex predators were from the same taxonomic family (here: Canidae, e.g., red foxes Vulpes vulpes), and (3) age‐dependent immune maturation contributes to the control of protozoan infection in wolves.

“…Protozoan parasites of the genus Sarcocystis are cystforming coccidians having an obligatory two-host preypredator life-cycle [1,2]. Asexual multiplication occurs in the intermediate host (IH), whereas sexual multiplication takes place in the small intestine of the definitive host (DH) [2,3].…”

Background: Birds of the family Laridae have not been intensively examined for infections with Sarcocystis spp. To date, sarcocysts of two species, S. lari and S. wobeseri, have been identified in the muscles of gulls. The aim of the present study was to evaluate the species richness of Sarcocystis in the herring gull, Larus argentatus, from Lithuania. Methods: In the period between 2013 and 2019, leg muscles of 35 herring gulls were examined for sarcocysts of Sarcocystis spp. Sarcocystis spp. were characterised morphologically based on a light microscopy study. Four sarcocysts isolated from the muscles of each infected bird were subjected to further molecular examination. Sarcocystis species were identified by means of ITS1 sequence analysis. Results: Sarcocysts were detected in 9/35 herring gulls (25.7%). Using light microscopy, one morphological type of sarcocysts was observed. Sarcocysts were microscopic, thread-like, had a smooth and thin (about 1 µm) cyst wall and were filled with banana-shaped bradyzoites. On the basis of ITS1 sequences, four Sarcocystis species, S. columbae, S. halieti, S. lari and S. wobeseri, were identified. Furthermore, it was demonstrated that a single infected herring gull could host two Sarcocystis species indistinguishable under light microscopy. Conclusions: Larus argentatus is the first bird species found to act as intermediate host of four Sarcocystis spp. According to current knowledge, five species, S. falcatula, S. calchasi, S. wobeseri, S. columbae and S. halieti can use birds belonging to different orders as intermediate hosts.

“…Prakas et al, (2012) has currently reported that more than 220 Sarcocystis species were found. Sarcocystosis is now recognized as an emerging protozoan disease in animals (Srivastava et al, 1977) and man (Juyal and Bhatia, 1989;Shah, 1995) and it has generated interest among veterinary protozoologists all over the world.…”

Sarcocystosis is a disease caused by Sarcocystis sp. of protozoan parasite and it has a zoonotic aspect. Four hundred forty one water buffaloes (Bubalus bubalis) were examined to assess zoonotic important protozoan and helminth parasites. Among them 441 buffalo samples were observed, only 285 (64.63%) buffaloes were infected with protozoan and helminth parasites. The total prevalence rate of protozoan parasite Sarcocystis sp. was the highest 124 (43.51%). The prevalence rate of five different areas of the country, the highest prevalence rate was found in Butwal 37 (49.46%) followed by Dharan 26 (48.14%), Kathmandu 22 (46.80%), Chitwan 38 (41.30%) and Nepalganj 18 (32.72%). So, in Nepal Sarcocystis sp. was most common parasite of water buffaloes and most of the human infection occurs by ingestion of raw or improperly cocked meat of infected animals. The risk of infection of Sarcocystis sp. was very high but not yet paid attention neither from the Government nor from the private sectors.
