mouse strain

A high-fat diet induced changes to the animals’ vaginal microbiomes that boosted survival after exposure to the virus.

Many researchers have stopped breeding mice, reduced the size of colonies, and established contingency plans in case animal care staff get sick.

Scientists find varied microbiota among the same strain of mice from four vendors—and that variability affects their susceptibility to infection.

Researchers have catalogued mutations in the coding regions of 36 of the most important mouse strains.
