Summary: This study identified two Sarcocystis species, S. arieticanis and S. tenella, for the first time in sheep from Lithuania using molecular methods. Both species were detected in all examined sheep, and have a high prevalence in the diaphragm, esophagus, and heart muscle samples of sheep. Further molecular epidemiological studies are needed to compare the prevalence of Sarcocystis species in various muscles of sheep raised in different geographic regions.

Summary: The study reveals a high prevalence of Sarcocystis DNA in cattle in Italy, with 67.8% in slaughter cattle and 90.7% in BEM condemned carcasses. The most prevalent species in slaughter cattle were S. cruzi, followed by S. bovifelis, S. hominis, and S. hirsuta. The presence of S. bovifelis and S. hominis was significantly higher in samples isolated from BEM condemned carcasses.

Summary: This study evaluated various sample preparation and polymerase chain reaction methods for identifying several Sarcocystis species in water samples. Eight Sarcocystis species were identified in water bodies in Lithuania, and nested PCR using species-specific primers targeting the cox1 gene was found to be the most appropriate method.

Summary: Members of the genus Sarcocystis are protozoan parasites that infect mammals, birds, and reptiles. Sarcocysts form in the muscles and central nervous system of the intermediate host, while oocysts and sporocysts develop in the small intestine of the definitive host. Corvids have been identified as potential definitive hosts for certain Sarcocystis species, with infections detected in a high percentage of examined birds.

Summary: This study describes a Sarcocystis species found in Chinese donkeys. The Sarcocysts were divided into two types based on their wall thickness, and genetic analysis showed high similarities between the Sarcocystis in donkeys and horses. However, cross-transmission between the two species was not successful.

Summary: The study identified Sarcocystis species in European mouflon, with high infection rates of Sarcocystis tenella and Sarcocystis arieticanis. The results showed that the digestion method is superior for molecular identification of Sarcocystis species in a certain host, compared to direct isolation of sarcocysts. Future research on Sarcocystis diversity in wild ovine and caprine species is needed.

Summary: The study found that American minks serve as hosts for many Sarcocystis species, with some infected minks carrying multiple Sarcocystis species, possibly originating from different species of deer. This raises concerns about compliance with game waste management rules by hunters and game processing companies. Further research on the involvement of mustelids in the transmission of various Sarcocystis spp. from different geographical locations is needed.

Summary: A study in Lithuania examined the diaphragm muscles of free-ranging red deer for Sarcocystis species, finding 7 confirmed species with considerable genetic variation. The discovery of Sarcocystis entzerothi in red deer was reported for the first time, shedding light on the diverse use of deer species as intermediate hosts. Additionally, genetic divergence was observed in the same Sarcocystis species using different hosts in the same geographical area and those using the same intermediate host species from different areas.

Summary: Protozoa of the genus Sarcocystis are obligate heterogenous parasites with both definitive and intermediate hosts. This study aimed to determine the main lesions that can occur in acute and chronic infections in intermediate hosts after ingesting infective sporocysts shed by opossums, using budgerigars as a model. The results showed that acute infection presented characteristic lesions in the liver and lungs, while chronic infection displayed mature cysts mainly in thigh and tongue muscles.

Summary: The study investigates a multilayer network in Brazil formed by interactions between bats, ectoparasites, and bacteria. Specific species were found to play crucial roles in the structure of the multilayer network. By using a multilayer approach, the study provides a better understanding of the roles of bats and ectoparasites as potential vectors and reservoirs of pathogens, as well as the modes of transmission.

Summary: The aim of this study was to investigate the occurrence of Leishmania infantum in South American coatis inhabiting two forest fragments in Campo Grande, Brazil. The results showed that 33 out of 110 coatis were infected with L. infantum, and the infection rate was significantly higher in the VBA area. The study suggested that the higher infection rate in VBA may be attributed to the presence of resident dogs and chickens, a denser population of coatis, and physical barriers in the surroundings.

Summary: Procyonids are reservoirs of tick-borne pathogens and other zoonotic infectious diseases. This study examined the prevalence of piroplasmids and Rickettsia in coatis and associated ticks in Brazil. The results showed the presence of Babesia spp. sequences in ticks, closely related to those found in capybaras and opossums, and Rickettsia sequences identical to Rickettsia belli and Spotted Fever Group species. These findings highlight the importance of Amblyomma spp. ticks in the maintenance of tick-borne agents in urban areas where humans and animals live together.

Summary: The present study aimed to detect hemotropic Mycoplasma spp. and Bartonella spp. in coatis from forested urban areas in midwestern Brazil. Two different hemoplasma genotypes were detected in coatis' blood samples, with 71% positive for myc1 and 17% positive for myc2. No Bartonella sp. was detected in coatis, but positive results were found in tick samples.

Through the analysis of collected specimens of P. tertius, P. coreodes, and P. arthuri, the researchers were able to differentiate the three species and confirm that Psammolestes should not be classified under the Rhodnius genus, contributing to Rhodniini taxonomy.

Summary: In Brazil, 69.88% of the 342 horses sampled were found to have Equine Protozoal Myeloencephalitis (EPM) caused by Sarcocystis neurona, while 51.75% of the horses were found to have EPM caused by Sarcocystis falcatula-like (Dal-CG23). Furthermore, 38.59% of the horses showed antibody reactions to both isolates.

Summary: Evaluation of physiological responses in free-living mammals is important for conservation, particularly for species living in human-modified environments. This study analyzed the blood parameters of South American coatis in urban forested areas and found that intrinsic factors and sampling sites influenced these variables. The results suggest that coatis in residential areas experience more stress than those in conservation units due to continuous exposure to humans and domestic animals.
