Hantavirus is a life-threatening disease transmitted by rodents, particularly deer mice. The virus is found in rodent urine and feces, but it does not make the host animal sick. It is believed that humans can become sick if they come in contact with contaminated dust from mice nests or droppings.
Many inbred and outbred strains of mice carry a recessive mutant allele of a coat color gene (or combinations of recessive alleles). These recessive mutations were useful to detect contamination of an inbred strain with either wild mice, or another inbred strain.
