pork and beef Flashcards
beef tapeworm
sagginatta
who are the hosts (sagginta)
definitive- humans
intermediate - cattle
live sagg
SI
what type of worm is beef tapeworm
CESTODES
IP sagginata
3 months
which one causes cysticercosis
solium
which one is longer
sagginata
which one has a greater impact on health
solium
whats the disease of saginata called
intestinal taeniasis
how do human become infected with beef one
have to eat the larval form in the beef ‘cystercosis bovis’- measly beef
how does the intermediate host get infected in t. saginata
cow eats eggs
main complaint from patient in sagginata
passing of the segment in the underwear but only the gravid segment
treatment of sagninatta
praziquantel/niclosclamide
infective form of saginata
cysticercosis ovis
t solium difference in size with sagginat
solium is 2X as broad
difference between eggs of solium and sagg
solium : infective to both man and pig
saginata- not infective to man just cow
how are the segments of solium passed
passively in chains
hosts in solium
man - definite - but can sometimes be intermediate
intermediate - pig
cystercoscos
when man is both the definitive and intermediate host
infective form in cystercoscosis -
EGGS
infective form in solium disease
larvae - cysticercosis cellulose
cystercoscosis most commonly affects
muscles
which one has unarmed scolex
saginnata
which one is larger
sagginata
treatment for cysticercosis
better to use albendazole+cs for neuroinfection
fish tapeworm
diphyllobothrium latum
fish disease
diphyllobothriasis
epi of fish disease
northern europe scandinavian countries
fish lives in
SI
MORPHOLOGY OF FISH ONE
WIDER THAN THEY ARE LONG
name for tapeworm
cestodes
infective form of fish tapeworm
humans have to eat larvae - plerocercoid larvae by eating fish like slamon and trout
stages of larval development
coracidium - comes out of operculum
procercoid
plerocercoid - infective form
what kind of water for fish tapeworm
fresh water
difference of morphology between fish and beef and pork
fish one has no suckers (both) and no rostellum (unlike solium)
signs of fish tapeworm
megaloblastic anemia , diarrhea, abdominal discomfort
are the eggs of fish tapeworm infective to humans
nope :)
tx of fish
praziquantel /niclosamide
hosts of the fish disease
defintive - human
1st intermediate - freshwater copepod
2nd - freshwater fish
dx of fish taperowm
eggs in feces - very unique
def host of granulises
DOGS
symptoms of h.nana
usually asymptomatic
size of nana
up to 4cm
which morphological features separate nana from counterparts
single row of suckers
how many proglottids nana has
> 200
route of infection
internal auto infection: egg hatches inside due to uterine pore
external auto infection;ingest own eggs
or egg eaten by a rat flea and then inside the flea it develops into cytseceroid larvae and humans ingest
tx of dwarf tapeworm
praziquantel
