Acanthocheilonema viteae in Mastomys coucha: chemotherapeutic and chemoprophylactic role of vitamin A in experimental filarial infection.

The role of vitamin A was evaluated for its chemotherapeutic and chemoprophylactic action against Acanthocheilonema viteae infection in Mastomys coucha. Vitamin A was administered for 10 days, five days before infection and five days post infection. On day 0 experimental animals as well as controls were infected with L3, the infective stage. Establishment of the worms revealed significantly less percentage of worm recovery over untreated controls. Cell-mediated response was found to be the cause of this reduction in worm recovery, whereas humoral response was not significant as IgG, IgA and IgM titres were low.
