Muscles of 25 bobcats (Lynx rufus) from remote areas Mississippi in 2017 were tested for parasites. Testing Sarcocystis infections included microscopic examination fresh unstained muscle squashes, pepsin digestion hearts and tongues, histological sections paraffin-embedded tissues. spp. detected the muscles 21 (84%) by a combination methods. Sarcocysts tongue squashes 2 bobcats. sp. bradyzoites digests 3 19 hearts, 12 tongues. In sections, sarcocysts 7 17 5 23 limb muscles. Based on...
Bison (Bison bison) and cattle (Bos taurus) are closely related (can interbreed) they also share many parasites. Cattle commonly infected with one or more of the eight named Sarcocystis species: hirsuta, S. cruzi, hominis, bovifelis, heydorni, bovini, sigmoideus rommeli. Among these, full life-cycle is known only for cruzi. cruzi (transmitted via canids) recognized as most pathogenic species, causing abortion, low milk yield poor body growth. It has been experimentally cross-transmitted from...
Morphologic development of unidentified Sarcocystis sp. schizonts associated with encephalitis in a 9-wk-old gray fox (Urocyon cinereoargenteus) from Texas is described. were confined to lesions. They sparsely distributed and their staining affinity for hematoxylin eosin varied developmental stages; immature deeply stained compared mature schizonts. Most parasites extravascular the host cell was not identified those that intracellular. The parasite divided by endopolygeny, which nucleus...
As predators of a wide variety livestock and wildlife species, wolves (Canis lupus) could serve as definitive hosts for species Sarcocystis parasites infecting many intermediate hosts. sporocysts have been observed in the feces fed infected beef before, but genetic tools not yet definitively identified which they harbor, impairing understanding their contribution to infections wild domesticated Therefore, we genetically characterized derived from small sample naturally Minnesota. Doing so...
Sarcocystis infections were found for the first time in muscles of 3 gray wolves (Canis lupus) from Minnesota. Two kinds (thin-walled and thick-walled) sarcocysts detected, based on appearance sarcocyst wall. In wolf 1, thin-walled (<0.5 μm), without any visible protrusions. Ultrastructurally, wall was type 1a identical to svanai domestic dog familiaris). The second kind sarcocyst, with a relatively thicker (>1 μm) wall, detected 2 3. had undulating, pleomorphic villar protrusion 9c; these...
Trichinella murrelli Pozio and La Rosa, 2000, is the primary sylvatic trichinellid encountered in temperate North America. During a survey for Sarcocystis wild canids, single worm matching morphology of encapsulated was observed muscle tissue squash from gray fox male originating Pennsylvania. The photographed then separated host by artificial digestion, genomic DNA extracted worm. This subjected to species-specific multiplex PCR short-read sequencing. banding pattern indicated that T....
Abstract Background Parasites in the apicomplexan genus Sarcocystis infect cattle worldwide. Assessing economic importance of each such parasite species requires proper diagnosis. cruzi, a thin-walled species, infects virtually all cattle. The prevalence other parasite, heydorni , remains less well established. remaining six have thick (> 3 µm) cyst walls ( hirsuta, S. hominis, bovifelis, bovini, sigmoideus and rommeli ). Thick-walled sarcocysts often induce inflammation striated muscles...
Rectal contents of 56 adult bobcats (Lynx rufus) in 2014 and 2017 from remote areas Mississippi were examined microscopically for parasite stages after the sugar flotation method. Among helminths, eggs/larvae found were: Paragonimus sp. 12, Toxocara cati-like 16, trichurid–capillaridlike 3, hookworms 27, lungworms 28. protozoa, oocysts/cysts Cystoisospora felis-like 2, rivolta-like 4, Cryptosporidium 1, Giardia 1. Additionally, numerous Sarcocystis sporocysts detected feces 12 bobcats;...
Abstract Currently, 7 named Sarcocystis species infect cattle: hirsuta , S. cruzi hominis bovifelis heydorni bovini and rommeli ; other, unnamed also cattle. Of these parasites of cattle, a complete life cycle description is known only for the most pathogenic in The was completed experimentally 1982, before related parasite were structurally characterized, advent molecular diagnostics; to our knowledge, no archived frozen tissues from cattle employed original descriptions remain DNA...
Hepatozoon sp. stages were detected in histological sections of the muscles 11 25 bobcats (Lynx rufus). Parasites from myocardium 11, tongues 4, and limb 5 these animals, which had been hunted Mississippi 2017. The intensity infection was highest heart. Only asexual (meronts) detected. Three types meronts (types 1, 2, 3) detected, based on structure mode division. Additionally, individual zoites found leukocytes blood vessels myocardium, but stage not identified. Based genomic DNA...
During a survey for Sarcocystis infections in Pennsylvania wild canids, muscles from the tongue and limb were examined microscopically sarcocysts. Between 9 February 2024 11 2024, muscle samples collected 76 coyotes, 46 gray foxes, 21 red foxes hunter harvested animals. Around 5 g of was by compression between glass slide coverslip. Trichinella murrelli larvae detected 1 coyotes (Canis latrans), (Urocyon cinereoargenteus), 7 (Vulpes vulpes) muscles. Diet individual host susceptibility...
