Q

Which should not be utilized to collect mites from the skin/spines of hedgehogs for analysis?
A) A toothbrush

Q

What is a likely reason mite infestation is so common in pet hedgehogs?

A

Subclinical infections are present and in stressful situations, the host-parasite relationship becomes imbalanced and parasite levels increase

20
Q

Which of the following is false regarding Caparinia infestation in hedgehogs?
A) Subclinical infections and direct life cycle of the mite likely contribute to commonality of the disease
B) Caparinia mites are implicated in the spread of dermatophyte infections in hedgehogs
C) While animals with acariasis are pruritic, this disease process rarely causes severe disease or fatality

A

C) severe infestation can result in infections, self-trauma, poor BCS and death
