kingdom- Animalia (unikonts)
Group- helminths
platyhelminths taxonomy
kingdom- Animalia (unikonts)
Group- helminths
phylum- Platyhelminthes
platyhelminths include what parasites
- flatworms
- flukes (trematodes)
- tapeworms (cestodes)
platyhelminths id
- bilat symetrica
- solid bodied like acoelomates
- excretory system is flame cell system
platyhelminths execretory system
flame cell system
digenetic trematodes taxonomy
kingdom- Animalia (unikonts) Group- helminths phylum- Platyhelminthes class- trematodes family- digenetic trematodes
digenetic trematodes lifecycle
- mollusk (snail) intermediate host (asexual multiplication)
- vertebrate final host (no multiplication here so what goes out comes in)
digenetic trematodes id
- solid body w/ syncytium
- anterior sucker around mouth and posterior sucker mid body
digenetic trematodes sex organs
- hermaphrodites have ovaries and testes
- oviduct filled with eggs
- operculate eggs (capped)
digenetic trematodes digestion
- have no anus so v+ up what they eat after divesting
digenetic trematodes development
- sporocysts and media (have mouths and crawl around inside snail eating things) developmental stages in snail
digenetic trematodes transmission brief
ingestion of metacercaria is how you get trematode
digenetic trematodes lifecycle
Eggs in feces/urine & environ -> Miracadium (swims) -> Asexual repro & sporocysts in mollusk -> Redia -> Cercaria (have tails) and leave snail -> Metacercaria -> Final hosts have adults
- Meso-cercaria – In some genera, cercaria does not have cyst wall
