These sporocysts of Sarcocystis characteristically contain four sporozoites and measure approximately 15-19 by 8-10 μm. (wikipedia.org)
Two cats experimentally infected with sarcocysts of S. fusiformis started shedding small numbers of sporocysts 8-10 days post-infection (dpi) and were euthanized 15 dpi. (bvsalud.org)
Sporocysts isolated from the intestinal mucosa of both cats were identified molecularly as belonging to S. fusiformis through PCR amplification and sequencing of the partial cox1. (bvsalud.org)

Sarcocystis is a genus of protozoan parasites, with many species infecting mammals, reptiles and birds. (wikipedia.org)
Transmission studies with Sarcocystis of cattle (then considered a single species, Sarcocystis fusiformis) in dogs, cats, and humans revealed three morphologically distinct species, which were named S. bovicanis, S. bovifelis, and S. bovihominis. (wikipedia.org)
The set of experimentally-determined sites in one species, Sarcocystis neurona, was further analyzed to evaluate the extent and significance of alternative poly(A) site choice in this organism. (bvsalud.org)
Sequence comparisons and phylogenetic analyses based on either 18S rRNA gene or cox1 nucleotide sequences, placed S. fusiformis closest to Sarcocystis cafferi from the African buffalo, but only the analyses based on cox1 data separated the two taxa clearly from each other and showed that they were separate species (monophyletic clusters and 93 % sequence identity at cox1 versus interleaved sequences and 98.7-99.1 % sequence identity at the 18S rRNA gene).
