Foals become infected with Parascaris equorum:
A) When they ingest larvated eggs from a contaminated environment
B) Transplacentally (in utero) from the somatic tissue stores in the mare
C) Transmammarily (via milk) from larvae mobilized from mare somatic tissue
D) By inadvertent ingestion of insect intermediate hosts when grazing

Which contraindicated when removing ticks
A) pour on
B) burn off
C) manual removal
D) dips

Burning may cause the ticks to become agitated and regurgitate their
stomach contents into the surrounding tissues they are feeding. This will
