1-2. What are the two genera of importance?
1. Paramphistomum spp. (cattle, moose, deer)
2. Cotyophoran spp. (sheep and goats)
2. where found in body?
just to go over the fluke anatomy again
as fluke matures the uterus becomes filled with eggs - and passes them out one at a time through the genital pore
1. more common in cervids or cattle/sheep?
1. similar to what?
1. what causes most damage?
2. how do they get throgh rumen?
3. how much damage to adults cause?
1. migration of juvenile adults
2. small intestine throught the abomasum
3. none usually
1. do they float?
2. what is different about them (in comparison to other fluke eggs)?
2. their are clear rather than reddish
1-2 what are the two species of importance?
2. in what?
3. how many?
1. local distribution limited by what?
1. IH availability
1-2. What is unique about the eggs?
1. prominent operculum (shoulders)
2. button/knob at end opposite the operculum
1. clincal signs/pathogensis?
2. what may experience chronic disease?
1. often none
most worms induce eosinophilia
eosinophilia = allergies and parasites
1. infects what?
1. definitive hosts?
1. look at pic
2. 1st is snail
2nd is salmonids (also giant salamander)
1. adult flukes in dogs penetrate deeply into mucosa
2. see clinical problems?
2. not usually
(salmon poisoning disease)
1. Rickettsial disease caused by what?
2. high mortality in what?
fluke is serving as vector for rickettsia
(Salmon Poisoning Disease)
1. cause what?
2. how relative to rickettsia?
3. how compared to SPD?
1. What is caused by Neorickettsia Risticii?
1. potomac horse fever
1. Definitive hosts?
2. regionally most common fluke encuountered in what?
1. intermeditate host(s)?
2. DH become infected by eating what?
3. Juvenile flukes may migrate extensively before maturing where?
1. 1st snails
1. how pathogenic?
1. not very
