Final answer:
Pearsonema plica is a parasitic worm whose predilection site is the urinary bladder of its host, typically affecting canines.
Step-by-step explanation:
The question you are asking relates to the field of biology, specifically parasitology. The term "Pearsonema plica" refers to a parasite, also known as the canine bladder worm. Its predilection site, which means the location within the host where the parasite prefers to live and is most commonly found, is the urinary bladder. Pearsonema plica is a parasitic worm whose predilection site is the urinary bladder of its host, typically affecting canines.
This parasite typically resides within the bladder lining or within the urinary tract of infected animals, where it can cause irritation and other symptoms. It is important for students studying veterinary science or biology to understand how parasites interact with their hosts, and knowing the predilection site is part of this knowledge.
