(Bcg/Lsh/Ity) gene was originally identified among inbred strains of mice that were susceptible to infection with several different intracellular pathogens, including Mycobacterium bovis, Leishmania donovani, Salmonella typhimurium, and M.
Genetic markers for screening animals for improved disease resistance (NRAMP
Some of them are heavy-metal ATPases, natural resistance-associated macrophage proteins (NRAMPs
), cation diffusion facilitators, the Zrt- and Irt- like proteins family, and the cation antiporters (Hall & Williams, 2003).
Several issues concerning the biochemical function of Nramp 1 with respect to intracellular survival of taxonomically unrelated pathogens remain unresolved.
