For example, Haller et al. found that congenic Balb/c and C57BL/6 mice expressing a functional (A2G) Mx1 were protected from lethal infection with two tick-borne members of the Orthomyxoviridae family, namely Thogoto Virus (THOV) and Dhori virus (DHOV) [39]. The gene discussed is MX1; the disease is infection.
