Cheyletiella is a contagious skin mite that lives on the keratin layer of skin and is about .385 millimeters in length. They have 8 legs and are in the Class Archanida #parasitology #parasitologia #parasite #veterinarymedicine #veterinarytechnician #vet #dvm #vetmed #veterinarian

Moniezia is a large cestode of cattle and sheep, and occasionally free ranging ungulates. They can be 4-5 meters in length #parasitology #parasite #vettech #veterinarymedicine #veterinarytechnician #vetschool #vetnurse #vetlife #vetstudent #dvm #vet #parasitologia #microbiology

Pinworm(Oxyurida) ova from bearded dragon fecal float. Do you see any other coccidian parasite in this slide? Pinworms are the most common parasite I see in reptiles. This nematode infect the large intestines, where adult females can lay hundreds of ova #vet #parasitology #dvm

Trichuris(whipworm) ova on the left and Hookworm to the right, canine fecal float. I tend to see these two parasites together often. Notice the bipolar plugs on the Trichuris ova. The thick shell of the Trichuris ova makes it very resistant to environmental extremes #parasitology

Scolex of Taenia tapeworm from a canine fecal #parasitology #parasitologia #parasite #veterinaryparasitology #vet #vettech #veterinarymedicine #vetnurse #vetstudent #veterinarian #veterinaryclinic #dvm

Demodex skin mite from a canine fecal. Demodex hatch as 6 legged nymphs, then molt into 8 legged adult mites. Demodex is in Class Archanida, along with other mites, spider, and ticks #veterinary #dvm #vettech #parasitology #parasite #demodex #veterinarian #Tierärztin #veteriner

Toxocara is the most common roundworm I see in USA. It can be transmitted to pups via the mammary glands during feeding #vet #parasitology #parasite #parasitologia #scientist #science #dvm #veterinária #veterinarymedicine #veterinarytechnician #vetschool #vetnurse #vettech #STEM

Zoonotic infection of Toxascaris into humans is less common than that of Toxocara, but has been documented. Notice the undulating inner membrane of the ovum. #parasitology #parasite #parasitologia #vet #vetstudent #veterinária #veterinarian #veterinary #vettech #vetnurse #dvm

Trichuris(whipworm) ova from a canine fecal. This nematode has a direct lifecycle and the infective stage is a larvated egg containing a first or second stage larva #parasitology #parasite #parasitologia #vet #vetstudent #veterinária #veterinarian #veterinary #vettech #scientist

Trichuris (whipworm) ovum on the left and Ancylostoma (Hookworm) on the right. From a canine fecal float. Adult Trichuris worms live in the caecum, where they "thread" their anterior ends into the mucosa #parasitology #parasite #vettech #veterinarymedicine #vet #dvm #veterinary

Cheyletiella skin mite and 2 Toxocara canis ova from a canine fecal float. 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 #parasitology #parasite #vet #vettech #vetnurse #dvm #STEM

Otodectes cynotis ear mite from a feline fecal float. Males have suckers on short pedicels on all legs, while females only have them on the 1st and 2nd pair of legs. #parasitology #parasite #parasitologia #vet #veterinaryparastiology #vetmed #veterinary #dvm #vettech #vetnurse

Cluster of Taenia spp ova from a canine fecal float. This tapeworm lives in the small intestines of canines and felines throughout most of the world. Taenia ova contains an embryo with 6 embryonic hooks, with a thick striated outer shell #parasitology #parasite #vettech #vet #dvm

2 Toxascaris leonina ova and a Toxocara canis ovum from a canine fecal float. These are the two most common roundworms I see in canines here in the USA #parasitology #parasite #vettech #scientist #science #dvm #microbiology #veterinario #veteriner #veterinária #veterinarymedicine

Cheyletiella skin mites from a canine fecal float. Do you notice any other parasites in this photo? Cheyletiella infects canines, felines, and lagomorphs. These mites do not borrow into the skin, but instead live and feed on the keratin level #parasitology #vet #vettech #dvm #4h

Trichuris (whipworm) and Toxascaris leonina ova from c canine fecal float. Notice the "bipolar plugs" at each pole of the Trichuris ovum. Adult Trichuris worms live in the caecum with their anterior heads threaded into the mucosa #parasitology #parasite #vet #vettech #vetnurse

That's a lot of cystoisospora! This coccidian parasite is highly species specific. Sporulated oocysts contain two sporocysts, which each contain four sporozoites. These protozoans undergo both sexual and asexual reproduction. #parasitology #parasite #vettech #veterinarymedicine

Lots of Taenia spp ova from a feline fecal float. Adult worms infect the small intestines of their host. Adult worms have ribbon-like segments that make up their body #parasitology #parasite #vettech #scientist #science #dvm #microbiology #veterinario #vetmed #veterinary #vet

Cheyletiella skin mite from a canine fecal float. These mites complete their entire lifecycle on the host. Adult females lay eggs they attach to hairs with fine threads. #parasitology #parasites #veterinary #vettech #veterinarymedicine #veterinarytechnician #vetnurse #dvm #STEM

Pinworm (Oxyurida) ova from a reptile fecal float. I see these often in reptiles here in central USA. There are over 850 known species in the Oxyurida order #dvm #vettech #parasitology #vet #parasites #veterinary #veterinario #veterinaryparastiology #scientist #science #stem
