“…Two studies using canine serum samples were conducted in the Brazilian states of Paraná (Koch et al, 2019) and Bahia (Oliveira et al, 2020). In both studies, low frequencies of seropositivity for S. neurona were found using IFAT, with 7/100 (7%) and 12/353 (3.4%) positive animals, respectively, with antibody titers reaching 100 (Oliveira et al, 2020) and 500 (Koch et al, 2019), thus indicating low exposure of these animals to the pathogen (Table 3). No association with neurological signs was observed by Koch et al (2019), who used 35 animals with neurological signs and 65 asymptomatic animals (p = 0.69).…”

Protozoan parasites of the genus Sarcocystis are obligatory heteroxenous cyst-forming coccidia that infect a wide variety of animals and encompass approximately 200 described species. At least four Sarcocystis spp. (S. falcatula, S. neurona, S. lindsayi and S. speeri) use opossums (Didelphis spp.) as definitive hosts, and two of them, S. neurona and S. falcatula, are known to cause disease in horses and birds, respectively. Opossums are restricted to the Americas, but their distribution in the Americas is heterogeneous. Five Didelphis spp. are distributed in South America (D. aurita, D. albiventris, D. marsupialis, D. imperfecta and D. pernigra) whereas just one opossum species (D. virginiana) is found in North America. Studies conducted in the last decades show that Sarcocystis spp., derived from South American Didelphis spp., have biological and genetic differences in relation to Sarcocystis spp. shed by the North American opossum D. virginiana. The aim of this review was to address the peculiar scenario of Sarcocystis species shed by South American opossums, with a special focus on diagnosis, epidemiology, and animal infections, as well as the genetic characteristics of these parasites.
