“…In another study, gametogonous development of S. levinei in the small intestine of dogs (Jain and Shah 1986a) was described. Buffalo-dog-buffalo cycle was further established by ensuing studies at Jabalpur (Ghoshal et al 1987b(Ghoshal et al , 1988. S. levinei was by far the commonest bubaline Sarcocystis species with predilection for oesophageal tissues and the patent period for sporocysts output in dogs was 15-74 days after being fed infected muscles (Ghoshal et al 1988).…”

Sarcocystis spp. are a group of tissue cystforming coccidia which infect a vast range of animals as well as human beings. Found frequently in animal carcasses at slaughter, undermining their value, they have also been found associated with clinical disease. Dogs and cats are involved in the transmission. Studies in India point to a vast reservoir of infection with high prevalence rates in various livestock species. However, there is a glaring paucity of reports on the horse and Sarcocystis of the camel has remained totally unexplored so far. At least two different Sarcocystis spp. can parasitize each livestock host species. Experimental transmission studies have provided additional parameters for distinguishing the species. The clinical symptoms are generally non-specific and diagnosis in the living animal, by the presently available means, is almost impossible. Immunodiagnosis till now is beset with problem of cross-reactivity. Treatment with anti-coccidials presently tried do not seem satisfactory. Of the two zoonotic species with cattle-man and pig-man cycles, only the latter seems of some significance in India due to backyard pig-rearing and slaughter practices. It is a paradox that despite high prevalence of S. suihominis in pigs, reports of human cases are limited. This and some of the existing grey areas of information in the Indian context, have been highlighted as also possible directions for future research.

“…As regards the life cycle of the S arcocystis spp. in water buffaloes, dogs have been found to act as definitive hosts for S. levinei [ 1 , 2 , 3 , 5 , 14 , 17 ], whereas cats have been shown to be definitive hosts for S. fusiformis [ 1 , 2 , 3 , 8 , 15 , 16 , 17 ] and S. buffalonis [ 13 ]. So far, the definitive host of S. sinensis has remained unknown.…”

The definitive hosts of Sarcocystis sinensis in water buffaloes have hitherto been unknown, but the close similarity of this species to the cat-transmitted Sarcocystis bovifelis in cattle suggested they were felids. In a previous study, two domestic cats were fed macroscopic sarcocysts of Sarcocystis fusiformis contained within or dissected from the esophageal muscles of water buffaloes, while no microscopic sarcocysts of S. sinensis were noticed. Both cats started shedding small numbers of sporocysts 8–10 days post infection (dpi) and were euthanized 15 dpi. Using a PCR-based molecular assay targeting the mitochondrial cox1 gene of S. fusiformis, both cats were shown to act as definitive hosts for this species. In the present study, DNA samples derived from oocysts/sporocysts in the intestinal mucosa of both cats were further examined by PCR for the presence of S. sinensis using 2 newly designed primers selectively targeting the cox1 gene of this species. All 6 DNA samples examined from each cat tested positive for S. sinensis. A 1,038-bp-long portion of cox1 was amplified and sequenced as 2 overlapping fragments from 5 of these DNA samples. The 5 sequences shared 99.3–100% identity with 7 previous cox1 sequences of S. sinensis obtained from sarcocysts in water buffaloes. Additionally, amplification of the ITS1 region with primers targeting various Sarcocystis spp., yielded amplicons of 2 different lengths, corresponding to those obtained from sarcocyst isolates of S. sinensis and S. fusiformis, respectively. This is the first study to show that cats act as definitive hosts for S. sinensis.
