Fungal burden in lungs and spleens of H. capsulatum-infected mice given MAb to Vβ10 (A and B), Vβ14 (C and D), or both (E and F). The mice were given MAb or an equal amount of rat IgG and/or rat IgM and infected with H. capsulatum. At days 7, 14, and 21, mice (n = 6/group) were sacrificed and lungs and spleens were assessed for the presence of H. capsulatum CFU.
