trichuris id
- shaped like bull whip where front end long and thin embedded in mucosa in syncitium
- thick posterior end dangles in lumen
trichuris relationship to cell and lumen
considered intracellular and extraluminal
trichuris lifecycle
direct lifecycle
trichuris transmission
- lemon shaped egg passed in feces
- infection via ingestion of egg containing L1
trichuris organ affected
cecum and colon
trichuris dx
- usually no dx
- can cause large bowel dx in massive numbers
trichuris dx in ppl
in ppl can live in rectum and case rectal prolapse

capillarids taxonomy
kingdom- Animalia
phylum-Nematoda- adenophorea
order- trichinelloidea
family- capillarids
capillarids host
mammals and other vertebrates
capillarids id
Whole body threaded within epithelial mucosa
- Front & back ends both thin
- Eggs also lemon shaped but kinda asymmetrica l w/ roughened/ striated surface
capillarids life cycle
- Direct life cycle or earthworm intermediate
capillarids transmission
ingestion of egg w/ L1 or paratenic host
capillarids dx
dx seldom serious
trichosomoides
kingdom- Animalia
phylum-Nematoda- adenophorea
order- trichinelloidea
family- trichosomoides
trichosomoides host
- mammals and 1 species in crocs/ birds
- mainly rodents
trichinella taxonomy
kingdom- Animalia
phylum-Nematoda- adenophorea
order- trichinelloidea
family- trichinella
trichinella lifecycle
pre larvae from female enter muscle instead of leaving feces
trichinella transmission
ingestion of L1 in raw meat
trichinella organ effected
mucosa of si
trichinella spiralis taxonomy
kingdom- Animalia
phylum-Nematoda- adenophorea
order- trichinelloidea
family- trichinella
trichinella spiralis host
- all mammals
- mainly pigs
- FINAL HOST BECOMES THE NEXT INTERMEDIATE
trichinella spiralis id
small
trichinella spiralis lifecycle
- Prelarvae migrate into blood -> Carried to muscle -> Enter striated muscle cells & mature becoming infectious to another host w/o molting
- Larvae encapsulate d & converts muscle cell into nest (nurse cell) by causing nuclear proliferation & angiogenesis to increase nutrient supply
trichinella spiralis transmission
- L1 liberated in stomach after being ingested from raw meat -> Small intestine mucosa -> Adult worms ->Mate -> Females make prelarvae which migrate to muscle
trichinella spiralis organ effected
- prelarvae enter many cell types including heart and brains but only ones in striated muscle become infective
trichinella spiralis dx
Trichinosis –
D & ulcer like pain
- Fever, facial swelling, small hemorrhage, swelling & weakness of involved muscle as prelarvae begin invading
- Loss of muscle function
- Can die of heart failure from larval migration (don’t mature in heart but pass through)
trichinella spiralis how to kill
freezing them kills them
trichinella spiralis us
- most commercial pork in us is safe
- REPORTABLE
dioctophymatoidea taxonomy
kingdom- Animalia
phylum-Nematoda- adenophorea
order- dioctophymatoidea
dioctophymatoidea id
- large muscular esophagus
- do not have tail
dioctophymatoidea lifecycle
- infectious stage are l3 in fish
- give birth to eggs
dictophyma renale taxonomy
kingdom- Animalia
phylum-Nematoda- adenophorea
order- dioctophymatoidea
dictophyma renale alt name
giant kidney worm
dictophyma renale host
- intermediate fresh water oligochaete
- amphibians and fish = paratenic
- fina= various mustelids, minks, relatives
dictophyma renale life cycle
Eggs in urine
- Larvae in fish do not grow & encyst on the stomach wall
- Fish ingested by mink -> Larvae penetrate into stomach wall causing V -> Migrate to liver -> Kidney
dictophyma renale dx
- dictophymatosis- severe v+
dictophyma renale in ppl
- rare
- tx = surgical removal
adenophorea include
- dicrophyma
- trichinelloidea
acanthocephala taxonomy
kingdom- Animalia
phylum- acanthocephala
acanthocephala alt name
spiny headed worms
acanthocephala host
- final = vertebrates of all classes
- first intermediate arthropod
- secondary intermediate or paretenic
acanthocephala eat how
- no intestinal tract so gain nutrients through tegument
acanthocephala id
- adults have spiny proboscis that they stay attached to intestinal mucosa with
acanthocephala organ/ cell effected
- egg passed in feces of host -> ingested by arthorpod intermediate (crustacean, insect ect.)
acanthocephala organ effected
intestines
acanthocephala location
world wide in freshwater and aquatic enivonrments
acanthocephala free living stages
NO FREE LIVING STAGES
