Veterinary Laboratory Procedures - Blood Parasites

Flashcard highlighting the concept of vectorborne blood parasites.

obligate intracellular gram negative bacteria

rickettsial parasites

genus of anaplasma that most commonly causes anaplasmosis in dogs

a. phagocytophilium

anaplasma genus that affects ruminants 

a. marginale 

cells affected by a. phagocytophilium

granulocytes - neutrophils, eosinophils, basophils

vector of a. phagocytophilium

ixodes spp.

vector of a. marginale

multiple tick genus/speciess

ehrilichia genus that usually causes ehrilichiosis in dogs

e. canis

cells affected by e. canis

mononuclear leukocytes - monocytes and lymphocytes

what is the rickettsia genus that causes rocky mountain spotted fever

rickettsia sickettsii

cells affected by rickettsia rickettsii 

endothelial cells lining vessels 

vectors for rickettsia rickettsii

rhipicephalus sanguineus, dermacentor variabilis

protozoal blood parasites 

babesia, cytauxoon felis, plasmodium 

what phylum are the protozoal parasites in

apicomplexa

which protozoan blood parasite affects cats and has a high mortality rate if not treated

cytauzoonfelis

what is the natural host of cytauzoon felis 

the bobcat

vector of cytauxoon felis

amblyomma americanum

which protozoan blood parasite cause avian malaria

plasmodium spp.

vector of plasmodium spp 

mosquitos 

epicellular bacterial parasite

mycoplasma haemofelis

what was mycoplasma haemofelis formally known as

haemobartonella felis

what disease does mycoplasma haemofelis cause 

feline infectious anemia 

why might you need to examine the blood smear several times of day if you suspect mycoplasma haemofelis

to detect cyclic parasitemia, as the number of parasites fluctuates throughout the day.

extracellular

vector of trypanosoma cruzi 

reduviid bug (kissing bug)

signs of disease - trypanosoma cruzi

lymphadenopathy, lethargy, splenomegaly/hepatomegaly, acute myocarditis

blood pathogens caused by Rhipicephalus sanguineous
