Toxascaris leonina eggs from a feline fecal. Toxascaris infection tends to be asymptomatic, but infection of kittens through the transplacental route can cause significant clinical disease. Zoonotic infection of Toxascaris into humans is less common than that of Toxocara #dvm

Taenia pisiformis tapeworm from a canine. Also known as the "rabbit tapeworm," this cestode infects lagomorphs, rodents, and carnivores. Lagomorphs are considered to be the intermediate host before infection in the small intestines of the definitive carnivore host, generally dogs

Cheyletiella skin mite. Mites are arachnids, that's why they have 8 legs. There's at least 5 different species of Cheyletiella. They can infect lagomorphs, cats and dogs. Notice how the palpi end with hook-like structures instead of suckers or claws #veterinario #vet #parasites

Whipworm (Trichuris) eggs from a canine fecal. These nematodes have a direct lifecycle. Adult worms infect the large intestines of their host. Humid environments are optimal for the development of larva. Generally not considered zoonotic, rare human cases have been reported #dvm

Cheyletiella skin mite and Toxocara canis ova from a canine fecal. Cheyletiella is in the Archanida class and adult mites have 4 pairs of legs. Its head has 2 large, prominent curved papal claws that point inwards. There is host specificity between different species #parasites

The scolex of a Taenia tapeworm. I found a very small tapeworm in a dog fecal sample. I put the worm on a microscope slide, put a few drops of saline on it, and pushed a coverslip onto it to get this photo. Notice the rostellum, hooks, and suckers #parasitology #vet #parasites

Hookworm eggs from a dog fecal. Hookworm gets its name because it's buccal capsule is bent dorsally in the form of a hook. Ancylostoma ova can be differentiated from Uncinaria by the smaller size of Ancylostoma #Parasitology #parasite #parasitologia #vet #veterinary #vettech

Can you name this parasite? Sample is from a farm dog fecal float who is around livestock animals #parasites #parasitology #Microbiology #vet

Dipylidium caninum egg packets from a canine fecal float. This tapeworm of the small intestines has an indirect lifecycle with fleas, and possibly chewing lice as intermediate hosts #parasitology #parasites #parasitologia #vet #vettech #microscope #microscopy #STEM

Lots of cystoisospora! Cystoisospora is an obligate coccidian protozoan parasite that infects cells of the intestines. This coccidian can reproduce both sexually and asexually. The unsporulated oocysts are oval shaped and usually about 50 x 30 micro meters in size #parasites

Capillaria(Eucoleus) boehmi egg from a canine fecal. Capillaria boehmi is known as the nasal capillarid, and infects the tissue membrane of the nasalcavityand sinuses. Capillaria boehmi can be differentiated from Capillaria aerophilus by how much the inner cell fills the membrane

Trichomonas foetus in a feline fecal float. This single celled flagellated protozoan parasite was once thought to only cause reproductive disease in cattle, but is now understood to be an important cause of clinical disease in cats. Diarrhea is a common symptom #parasitology #dvm

Dipylidium ova packets inside a tapeworm segment. When I find a segment or proglottid in a fecal sample, I put it on a microscope slide, add a few drops of saline, then press a coverslip down. If it is gravid, the ova will appear #parasitology #microscopy #microscope #vettech

Cystoisospora from a canine fecal. This is one of the 1st microscope photos I took years ago. The tissue stage of this protozoan parasite reproduces both sexually and asexually in the enterocytes of the small intestines of the host #parasitology #parasite #vettech #scientist #dvm

Otodectes cynotis ear mite from a feline fecal. Otodectes is fairly common throughout most of the world. It is primarily transmitted through direct contact with an infested animal, and transmission can be particularly common during the neonatal period #parasite #parasitology #dvm

Nematodirus spp egg. Do you see any other parasites in this photo? Nematodirus is a genus of roundworm, commonly known as thread-neck worms, that infects bovine, ovine, and caprine. They are not known to affect canines, felines, swine, or humans #parasites #parasitology #vet #dvm

2 Toxocara canis and 3 Toxascaris leonina eggs from a Canine fecal float. These are the two most common roundworms I see in canines. Notice the thick pitted outer membrane of Toxocara and the undulating inner membrane of Toxascaris #parasitology #microscopy #microscope #vet #dvm

Whipworm (Trichuris) on the top and Hookworm (Ancylostoma) from a canine fecal float sample. Whipworm gets its name from having a broad short posterior end and a very long and narrow whip-like anterior. I see these two parasites together fairly commonly #vet #vettech #parasites
