Helping protect the bond between veterinary clients and pets through parasite control

Controlling parasites protects the human-animal bond, ensuring that fleas, ticks and internal parasites don't come between pets and their owners while also protecting pet and public health.

Symbiosis in parasitology: Heartworm recommendations updated

The National Center for Veterinary Parasitology and Companion Animal Parasite Council address emerging needs in understanding and managing heartworms and other complex parasites.

Tick biology and behavior (Proceedings)

The common ticks on dogs and cats in North America are all three host ticks. Accordingly, the larvae, nymphs, and adults of each species must each quest, attach to a host, and feed before leaving the host to molt or deposit eggs in the environment.

Tick-borne diseases: Lyme borreliosis and anaplasmosis (Proceedings)

Testing for Lyme disease and anaplasmosis often involves detection of antibodies. Antibodies may be detected on a patient-side assay such as the 3Dx/4Dx SNAP tests or using IFA at a reference lab. The SNAP test uses C6 as the target antigen and thus the B. burgdorferi result is very specific.
