CD79A and coinfection: Immune suppression by nematodes can, for instance, facilitate tuberculosis infections in African buffalo (Syncerus caffer84), a reduction of parasite-specific IgA antibodies following co-infection with multiple intestinal parasites increases parasite burden in wild wood mice (Apodemus sylvaticus85), and concurrent bacterial and viral infections shape the gut microbial diversity in bank voles (Myodes glareolus86).
