16
Q

What are the intermediate hosts of A. canis and A. marcianae?

A

Snail- miracidium enters snail and develops to Cercaria
Tadpole- Cercaria in tadpole develops to infective mesocercaria

17
Q

Infective stage of A. canis and A. marcianae

A

Definitive host infected by eating a tadpole with the Mesocercaria or paratenic host
Mesocercaria becomes a metacercaria in lungs before reaching intestines of definitive host
Adult flukes pass egg in feces that don’t contain a miracidium

18
Q

T/F: A. marcianae can be transmitted transmammary

A

TRUE

19
Q

Clinical signs of A. canis and A. marcianae

A

Enteritis and lung inflammation with bleeding

20
Q

How do you diagnose A. canis and A. marcianae?

A

Fecal sedimentation
Acid acetate sedimentation

21
Q

Treatment and prevention of A. canis and A. marcianae

A

Praziquantel
Restrict from eating tadpoles or paratenic hosts that may ingest tadpoles (frogs, rodent, etc.)

22
Q

What e the hosts and location of Platynosomum fastosum?

A

Cats
Bile and pancreatic ducts

23
Q

Characteristics of Platynosomum fastosum

A

Body: small flukes (<1 cm long)
Eggs: with a meracidium and a single operculum

24
Q

Distribution of Platynosomum fastosum

A

Southern US and Carribean

25
Q

Lifecycle of Platynosomum fastosum

A

Indirect
Cats become infected by eating paratenic host containing Metacercaria

26
Q

Intermediate hosts of Platynosomum fastosum

A

Snail- Miracidium in eggs develops to Cercaria in snail
Pill bug- 2nd intermediate host containing the infective Metacercaria is eaten by paratenic host (lizard)

27

32
Q

Why are the host and infective stage of Schistosoma and Heterobilharzia?

A

Dogs (horse)
Cercaria

33
Q

Pathogenicity/ clinical signs of Schistosoma and Heterobilharzia
