14 - Trematodes: rumen, lung, intestinal Flashcards
1-2. What are the two genera of importance?

- Paramphistomum spp. (cattle, moose, deer)
- Cotyophoran spp. (sheep and goats)
(Rumen flukes)
- color
- 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
- more common in cervids or cattle/sheep?

1.

(Rumen Flukes)
(Life Cycle)
- similar to what?

(Rumen Flukes)
(Pathology)
- what causes most damage?
- how do they get throgh rumen?
- how much damage to adults cause?
- migration of juvenile adults
- small intestine throught the abomasum
- none usually

(Rumen Flukes)
(eggs)
- do they float?
- what is different about them (in comparison to other fluke eggs)?
- no
- their are clear rather than reddish

(Lung Flukes)
1-2 what are the two species of importance?

(Paragonimus Kellitcotti)
(Hosts)
- definitive?
- intermediate?

(Lung Flukes)
(Paragonimus Kellicotti)
- location?
- in what?
- how many?

- local distribution limited by what?

- IH availability

(Lung Flukes)
(Paragonimus Kellicotti)
1-2. What is unique about the eggs?
- prominent operculum (shoulders)
- button/knob at end opposite the operculum

(Lung Flukes)
(Paragonimus Kellicotti)


(Lung Flukes)
(Paragonimus Kellicotti)
- clincal signs/pathogensis?
- what may experience chronic disease?
- often none
- cats/dogs

most worms induce eosinophilia
eosinophilia = allergies and parasites



(Paragonimus Westermani)
- infects what?
- humans

(Intestinal Flukes)
Nanophyetus Salmonicola
- definitive hosts?
- intermediate

- look at pic
- 1st is snail
2nd is salmonids (also giant salamander)





(nanophyetus salmonicola)
(Pathogenecitiy)
- adult flukes in dogs penetrate deeply into mucosa
- see clinical problems?
- not usually

(nanophyetus salmonicola)
(salmon poisoning disease)
- Rickettsial disease caused by what?
- high mortality in what?

fluke is serving as vector for rickettsia

(Salmon Poisoning Disease)


(nanophyetus salmonicola)
(Neorickettsia elokominica)
- cause what?
- how relative to rickettsia?
- how compared to SPD?

(nanophyetus salmonicola)
- What is caused by Neorickettsia Risticii?
- potomac horse fever

(Alaria spp.)
- Definitive hosts?
- regionally most common fluke encuountered in what?
- pathogenic?

(Alaria spp.)
- intermeditate host(s)?
- DH become infected by eating what?
- Juvenile flukes may migrate extensively before maturing where?
- 1st snails
2nd frogs

(Alaria spp.)
- how pathogenic?
- not very
NO APPROVED TREATMENT
