A colleague bought some nude mice and they all died on day 2 after delivery to lab. She was puzzled why because the condition of the room was standard. She did a PCR test on their liver and found out all of them had MHV virus infection. She told the company but they don't take responsibility and say it must have been from our own mishandling.
Therefore she wants to establish a routine test procedure for mice they buy from companies to not have the same problem again. What does she need to do? Or what tests the companies do on mice before they send them to customers?
