“…Suitable intermediate hosts for S. singaporensis include all of Rattus and Bandicota species as well as Nesokia indica [20,28-30]. Furthermore, S. singaporensis is endemic in Southeast Asia [31-34], and considered to be highly pathogenic. In fact, it can be lethal due to extensive development of schizonts in rat endothelial cells [28].…”

BackgroundSarcocystis species are protozoan parasites with a wide host range including snakes. Although there were several reports of Sarcocytis species in snakes, their distribution and prevalence are still not fully explored.MethodsIn this study, fecal specimens of several snake species in Malaysia were examined for the presence of Sarcocystis by PCR of 18S rDNA sequence. Microscopy examination of the fecal specimens for sporocysts was not carried as it was difficult to determine the species of the infecting Sarcocystis.ResultsOf the 28 snake fecal specimens, 7 were positive by PCR. BLASTn and phylogenetic analyses of the amplified 18S rDNA sequences revealed the snakes were infected with either S. nesbitti, S. singaporensis, S. zuoi or undefined Sarcocystis species.ConclusionThis study is the first to report Sarcocystis infection in a cobra, and S. nesbitti in a reticulated python.

“…In Malaysia, sarcocystosis has been reported in wild animals, such as slow loris [25], rodents [26], and long-tailed monkeys [27,28]. Worldwide, sarcocysts have been found in many types of wild animals as discussed before.…”

“…In Malaysia, sarcocystosis was reported in humans [17][18][19][20][21][22][23][24], and domestic and wild animals [25][26][27][28]. The incidence of Sarcocystis infection in wild captive zoo animals in Malaysia is relatively unknown.…”

Sarcocystis sp. infection was investigated in 20 necropsied captive wild mammals and 20 birds in 2 petting zoos in Malaysia. The gross post-mortem lesions in mammals showed marbling of the liver with uniform congestion of the intestine, and for birds, there was atrophy of the sternal muscles with hemorrhage and edema of the lungs in 2 birds. Naked eye examination was used for detection of macroscopic sarcocysts, and muscle squash for microscopic type. Only microscopically visible cysts were detected in 8 animals and species identification was not possible. Histological examination of the sections of infected skeletal muscles showed more than 5 sarcocysts in each specimen. No leukocytic infiltration was seen in affected organs. The shape of the cysts was elongated or circular, and the mean size reached 254 × 24.5 mm and the thickness of the wall up to 2.5 mm. Two stages were recognized in the cysts, the peripheral metrocytes and large numbers of crescent shaped merozoites. Out of 40 animals examined, 3 mammals and 5 birds were positive (20%). The infection rate was 15% and 25% in mammals and birds, respectively. Regarding the organs, the infection rate was 50% in the skeletal muscles followed by tongue and heart (37.5%), diaphragm (25%), and esophagus (12.5%). Further ultrastructural studies are required to identify the species of Sarcocystis that infect captive wild animals and their possible role in zoonosis.

“…Here, we examined two new Sarcocystis -isolates infecting colubrid snakes and rodents in Southeast Asia, also applying new methodological approaches. We describe a new Sarcocystis species from mangrove snakes ( Boiga dendrophila ) in Thailand and named it after the investigator who first observed the parasite in rodents in Malaysia ( Kan, 1979 ), embedding this into a broader examination of the morphological and molecular (nuclear 18S rRNA and mitochondrial cox1 ) characteristics of established Sarcocystis spp. and unidentified isolates that cluster in the S. zuoi – complex.…”
