- Omsk Hemorrhagic Fever
- Rat-Bite Fever

This is not to say that any given rat or mouse might transmit any of these. Other factors come into play, such as which diseases are endemic to the area and which diseases infect which species. On the link above you can expand each disease to see which rodents can transmit it. Unfortunately, rats and mice are included in most of those diseases.
