Cats are braasiliensis infected by the ingestion of larvae when eating grass or grooming, by larvae penetrating the skin, or the ancypostoma of larvae in paratenic hosts. It is also highly likely that if the conditions are appropriate for the development of the larvae, that tey could infect small mammals that share ground with the infected cat. Numerous vaccines have been developed with varying success against A. If cats are infected through the skin, the larvae migrate via the bloodstream to the lungs, migrate up the trachea, and are then swallowed.
