Interferon-gamma deficiency reveals that 129Sv mice are inherently more susceptible to Anaplasma phagocytophilum than C57BL/6 mice.
Immunocompetent mice 129Sv (129) and C57BL/6 (B6) mice are similarly susceptible to Anaplasma phagocytophilum. We now show that 129 mice lacking interferon-gamma (IFN-gamma) develop more severe infection with A. phagocytophilum than IFN-gamma deficient B6 mice. These data demonstrate that there is an inherent increased susceptibility of 129 mice, compared with B6 mice, to A. phagocytophilum that can only be discerned in the absence of IFN-gamma.
