25
capillarids host
mammals and other vertebrates
26
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
27
capillarids life cycle
- Direct life cycle or earthworm intermediate
28
capillarids transmission
ingestion of egg w/ L1 or paratenic host
29
capillarids dx
dx seldom serious
30
trichosomoides
kingdom- Animalia phylum-Nematoda- adenophorea order- trichinelloidea family- trichosomoides
31
trichosomoides host
- mammals and 1 species in crocs/ birds | - mainly rodents
32
trichinella taxonomy
kingdom- Animalia phylum-Nematoda- adenophorea order- trichinelloidea family- trichinella
33
trichinella lifecycle
pre larvae from female enter muscle instead of leaving feces
34
trichinella transmission
ingestion of L1 in raw meat
35
trichinella organ effected
mucosa of si
36
trichinella spiralis taxonomy
kingdom- Animalia phylum-Nematoda- adenophorea order- trichinelloidea family- trichinella
37
trichinella spiralis host
- all mammals - mainly pigs - FINAL HOST BECOMES THE NEXT INTERMEDIATE
38
trichinella spiralis id
small
39
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
40
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
41
trichinella spiralis organ effected
- prelarvae enter many cell types including heart and brains but only ones in striated muscle become infective
42
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)
43
trichinella spiralis how to kill
freezing them kills them
44
trichinella spiralis us
- most commercial pork in us is safe | - REPORTABLE
45
dioctophymatoidea taxonomy
kingdom- Animalia phylum-Nematoda- adenophorea order- dioctophymatoidea
46
dioctophymatoidea id
- large muscular esophagus | - do not have tail
47
dioctophymatoidea lifecycle
- infectious stage are l3 in fish | - give birth to eggs
48
dictophyma renale taxonomy
kingdom- Animalia phylum-Nematoda- adenophorea order- dioctophymatoidea
49
dictophyma renale alt name
giant kidney worm
50
dictophyma renale host
- intermediate fresh water oligochaete - amphibians and fish = paratenic - fina= various mustelids, minks, relatives
51
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
52
dictophyma renale dx
- dictophymatosis- severe v+
53
dictophyma renale in ppl
- rare | - tx = surgical removal
54
adenophorea include
- dicrophyma | - trichinelloidea
55

spiny headed worms
57
acanthocephala host
- final = vertebrates of all classes - first intermediate arthropod - secondary intermediate or paretenic
58
acanthocephala eat how
- no intestinal tract so gain nutrients through tegument
59
acanthocephala id
- adults have spiny proboscis that they stay attached to intestinal mucosa with
60
acanthocephala organ/ cell effected
- egg passed in feces of host -> ingested by arthorpod intermediate (crustacean, insect ect.)
61
acanthocephala organ effected
intestines
62
acanthocephala location
world wide in freshwater and aquatic enivonrments
63
acanthocephala free living stages
NO FREE LIVING STAGES
64

kingdom- Animalia | phylum- acanthocephala
65
macracanthorhychus hirudinaceus host
- pig final | - beetle intermediate
66
macaracanthorhynchus ingens taxonomy
kingdom- Animalia | phylum- acanthocephala
67
macaracanthoryhynchus ingens host
- dog and raccoon = final | - millipede = intermediate
