About 99% of mouse genes have a homolog in the human genome, and for 80% of these genes, the best match in the human genome has, in turn, its best match against the orthologous mouse gene in the conserved syntenic interval.
According to the Center for Disease Control (CDC), mice spread numerous diseases worldwide. The diseases are spread to humans directly: through contact with mice feces, saliva or urine, mouse bites and mere contact. Mouse diseases, however, can also be spread indirectly: ticks, fleas and mites that have fed, at some point, on the infected mouse and then transmit that infection to humans.
