order- muscoflagellates
mucosoflagellates what family
- trichomonadida
- diplomonadida
- naegleria
trichomonadida id
- pear shaped w/ single nucleus
- 3-5 anterior flagella w/ undulating membrane
trichomonadida transmission
- transmitted from host to host in feces or genital fluids
- do not have cyst stage involved in transmission

cat
tritrichomonas blagburni transmission
direct feal-oral contact
tritrichomonas blagburni dx
large bowel d+
tritrichomonas blagburni vs tritrichomonas foetus
many believe they’re the same but gene sequencing and pathogeniciticy say otherwise
histomonas meleagridis taxnomy
- kingdom- protozoa
- class- excavata
order- muscoflagellates
family- trichomonadida
histomonas meleagridis host
- chickens
- turkey
- gallinaceous birds
histomonas meleagridis transmission
through egg of nematode (heterakis gallinarum)
histomonas meleagridis organ effected
cecum and liver
histomonas meleagridis dx
- sulfer colored d+ in turkeys bc infection of liver
- chickens cecal lesions
- called blackhead?
diplomonadida taxnomy
- kingdom- protozoa
- class- excavata
order- muscoflagellates
family- diplomonadida
diplomonadida transmission
transmission from host to host in feces or genital fluids
diplomonadida organ effected

giardia taxnomy
- kingdom- protozoa
- class- excavata
order- muscoflagellates
family- diplomonadida
giardia hosts
- fish
- amphibia
- birds
- mammals
giardia lifecycle
- Cyst in external environ -> ingested by vertebrate -> Excystation in small intestines -> Multiply by binary fission -> Trophozoite stays in mucosa or becomes cyst -> Excreted as cyst which cont cycle or trophozoite which disintegrates
giardia id
- 2 nuclei
- 6 anterior and 2 posterior flagella
giardia transmisssion
- cyst is stage passed from host to host (monotonous lifecycle)
- Ingestion of cysts in contaminated water, food, or by contact w/ infected individuals or fomites
giardia organ affected
small intestine vertebrates
giardia trophozoite form transmission
- Trophpo-zoites passed in stool but do not survive in environ
giardia trophozoite form motility
Trophpzoite form swim around attached to mucosa by sucking discs on bottom & use flagella to pump out water so stick better
giardia cysts special characteristics
Glycoproteins that come out & bubble to surface forming open meshwork cyst instead of hard cyst that lasts years
naegleria taxonomy
- kingdom- protozoa
- class- excavata
order- muscoflagellates
family- naegleria
naegleria host
- facultative amoeba free living most of the time but serious dx if enter vertebrate
naegleria organ/ cell effected
- nostrils = where become pathogenic
- brain
naegleria dx
- fatal fulminant primary amoebic meningoencephalitis b/c feed and reproduce v rapidly in brain
naegleria fowleri taxnomy
- kingdom- protozoa
- class- excavata
order- muscoflagellates
family- naegleria
naegleria fowleri host
- humans
- sheep
- cattle
- tapir
naegleria fowleri lifecycle
3 stages
- cyst
- trophozoite
- flagellated form
naegleria fowleri transmission
go up nose during water activities
naegleria fowleri organ effected
- migrate to brain from nasal cavity via olfactory nerves
- trophozoite in css and tissue
- flagellated form occasionally in csf
