1. In Eastern Canada, the expansion of canine Lyme disease has been attributed largely to: *

climate change and excessive rainfall.

tick movement via migratory, ground-feeding birds.

recent mutations within the genome of Borrelia burgdorferi.

the ability of tick species, other than Ixodes, to carry and transmit Borrelia burgdorferi.

2. If the minimum recommended interval between the two initial doses of Lyme disease vaccines is 2 weeks, what is the maximum recommended interval? *

4 weeks

6 weeks

2 months

6 months

3. Following recovery from Lyme disease, a dog: *

develops lifelong immunity.

should NOT be vaccinated against Lyme disease due to risk of causing protein-losing nephropathy.

should be vaccinated against Lyme disease since natural immunity following infection is short-lived (weeks).

will have a NEGATIVE test result for all outer surface proteins.

4. Complete clearance of Borrelia burgdorferi from a naturally infected dog using an antimicrobial is: *

accomplished with doxycycline, PO, 10 mg/kg, bid for 30 days.

accomplished with azithromycin, PO, 25 mg/kg, once daily for 10-20 days.

accomplished with cefovecin, SQ, 8 mg/kg, 2 injections 14 days apart.

unlikely.

5. Protection following vaccination with any Lyme disease vaccine is achieved through which one of the following mechanisms? *

OspA antibody that neutralizes circulating B. burgdorferi

OspC antibody that neutralizes circulating B. burgdorferi

OspA antibody that binds to B. burgdorferi in the mid-gut of the tick and prevents transmission

OspC antibody that binds to B. burgdorferi in the mid-gut of the tick and prevents transmission
