Arthropod Phylum: Animalia Kingdom

1. Serve as a casual agent
2. may serve as vector for bacteria
3. May produce toxins or venomous sub.
4. May serve as int. host for leeches and protozoans
Trematodes, tapeworms, pseudotapeworms, roundworms, thorny headed worms, leeches, & Arthropods are in What KINGDOM?
Animalia

1. flagellated
2. Ameboid
3. Apicomplexans
4. Ciliated
Characteristics of The Protozoans?
Unicellar organisms
Vary in Size & Shape
Most are microscopic
Most parasites in this kingdom are free living. They cause considerable damage in domestic animals, horses, cows, sheeps, etc. What is this kingdom?
Protista
Most Important Phylums in the The Protista kingdom are?
1. Sarcomastigophora
2. Ciliophora
3. Apicomplexa
Flagellated, live in host blood, lymphatic fluid, or cerbro. spinal fluid. Are ofter pear or bullet shaped, swim in host's body fluid, and vary greatly in Pathogenicity. Name the flagellate?
Mastigophora. Protista kingdom. Sarcomastigophora phlym.
Move by pseudopodia. Two forms Motile trophozoite and Resistant cyst. Ill defined in shape. Vary in pathogenicity. Name the sub-phylum and the most important parasite?
Mastigophora, Entamoeba histolyica.
Sarcodina Amoeba that causes amoebic dysentery in humans. Dogs usually acquire from humans, cats rarely infected. Will produce chronic diarrhea in dogs. Diagnosed with fecal. Will be able to see cyst and trophozoite.
Entamobea Histolyica
In Etamoeba Histolyica how do the cells multiply?
Miotic divison. one cell into two..Etc.
Important parasite of large and small animals. Parasites are flattened leaf shaped. Primarily encoparasites of the GI tract. Can infect blood vessels and lungs. Often identified in feces. Name the class and Phylum?
Digenetic Trematodes (Flukes), Platyhelminthes(flat worms).
Ribbon like flatworms found in the GI tract of their definite host. Eggs are usually found through fecal flotation. Name Kingdom, Phylum, and Class?
Animalia, Platyhelminthes, Eucestodes(tape worms)
Round in their cross section. Most numerous, complex, $ variable amongthe worm parasites in dometic animals. Name Kingdom,and Class?
Animalia, Nematodes (round worms)
Parasite that comes in all sizes and shapes, exist in a variety of organs, produce significant pathology in domestic animals. Second only to Anthropods in their number and complexity in life cycles. Larvae and eggs on fecal flotation. Name Phylum and class?
Nematoda. Nematodes (round worms)
Protozoan covered with tiny hairs over most of their body. Two forms: trophozoite and cyst. Come in a variety of shapes and size. Name Kingdom, phylum, and sub-phylum?
Protista, Sarcomastigophora, Ciliphora (Ciliaties)
Large Protozoan parasite that is found in the cecum and colon of dogs and horses. Produces diarrhea. More closely associated with pigs and it is found in their large intestine. Observed in fecal and genrally considered to be non-pathogenic. Name the Kingdom, Phylum, sub-phylum, and Class?
Protista, Sarcomastigophora, Ciliphora, Balantidium Coli.
Protozoan parasite that is the most diverse, most complicated parasite of almost every animal phylum. Name the kingdom, phylum, and subphylum?
Protista, Sarcomastigophora, Apicomplexa (coccidians) sporozoa.
In domestic animals found in the epi. of the intestine, w/in the blood cells and w/in clees of the reticuloendothelial system. Are banna, comma and boomerang shape. Movement not visible by the human eye.
Apicomplexa
Coccidian parasite found in the small intestine of dogs and cats. Produce Clinical syndrome known as coccidiosis. Commonly diagnosed in puppies and kittens. Oocyst is the stage seen in fecal flotation.. Name?
Isospora Species. Coccidian. Apicomplexa. Sarcamastigophora. Protista.
Protozoan parasite that is an intestinal coccidian of cats. Found in fecal and variety of blood tests. Final host is all cats. Serious pathogen in pregnant women. Most infections via the digestive tract. Infection in 2 ways: ingestion of eggs shed in feces. or undercooked meat that is contaminated.
Toxoplasma Gondii. Apicomplexa. Protista.
Intracellular parasite found in the red blood cells of dogs. Referred to as the Canine Piroplasm. Diagnosis: ring of organisms in red blood cells. Spread by the bite of ticks. Prognosis is Poor.

spores.. Sporozoa
Flagellate found in the bloodstream and tissues of vertebrates. All have anthropod vectors in which transmisson is either cylical or non-cylical. Bats are also the host. Dog,Cats, and wild carnivores may become infected by eating fresh carcasses of animals that have died from this. Name?
