A

ingestion of egg w/ L1 or paratenic host

29

- mainly rodents

32
Q

trichinella taxonomy

A

kingdom- Animalia
phylum-Nematoda- adenophorea
order- trichinelloidea
family- trichinella

33
Q

trichinella lifecycle

A

pre larvae from female enter muscle instead of leaving feces

34
Q

trichinella transmission

A

ingestion of L1 in raw meat

35
Q

trichinella organ effected

A

mucosa of si

36
Q

trichinella spiralis taxonomy

A

kingdom- Animalia
phylum-Nematoda- adenophorea
order- trichinelloidea
family- trichinella

37
Q

trichinella spiralis host

A
  • all mammals
  • mainly pigs
  • FINAL HOST BECOMES THE NEXT INTERMEDIATE
38
Q

trichinella spiralis id

A

small

39
Q

trichinella spiralis lifecycle

A
  • 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
40
Q

trichinella spiralis transmission

A
  • L1 liberated in stomach after being ingested from raw meat -> Small intestine mucosa -> Adult worms ->Mate -> Females make prelarvae which migrate to muscle
41
Q

trichinella spiralis organ effected

A
  • prelarvae enter many cell types including heart and brains but only ones in striated muscle become infective
42
Q

trichinella spiralis dx

A

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)

43
Q

trichinella spiralis how to kill

A

freezing them kills them

44
Q

trichinella spiralis us

A
  • most commercial pork in us is safe

- REPORTABLE

45
Q

dioctophymatoidea taxonomy

A

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
52
