I would also be worried about the possibility of these new rats carrying virsues such as SDA, Sendai or KRV, especially with rat pups present in the home. This is why EVERYONE who takes in new rodents must (if possible!) quarantine them in a seperate household for at least four weeks before bringing them to your home and introducing them to your current rats. Sometimes there is no way to use a seperate household, of there is an urgent need and the animals must be brought home without quarantine. If you cannot quarantine in a seperate household it is best to keep them in another room with the door shut as far away from the others as possible. There is no reason why you need to give the rats up, as Christy said all rats are Myco carriers unless bred pathogen free. It's not airborn but spread by direct contact, highly contagious and there is no cure.
I DO NOT recommend treating Myco rats with Tetracycline. The best meds for Myco outbreaks are Baytril (should not be given to younger rats due to stunted growth) and Doxycycline. There is also a new drug out on the market not yet prescribed for rats but I do not recall the name. It works better than Baytril, which is the best meds for Myco. Tylan is also an OK medication to treat them. But until you assume it is a Myco outbreak think of all the things that cause sneezing. Is or was the bedding dirty with amonia buildup? What bedding were the rats on? Rats should only be housed on aspen, no pine or cedar due to toxic phenols which cause respiratory distress. Carefresh is also a good bedding but can sometimes be dusty, and Tek Fresh is also recommend, as well as Yesterday's news etc. Are the rats overly stressed? That too can cause staining and sneezing. Rats do sneeze on accasion, and it's completely normal, but over sneezing is not a good sign. I would give them a few days to settle in and try to keep them away from your rats as long as possible. Just remember that the next time you introduce any new rodents into the home proper quarantine must be done.
If you want to keep these rats you can ask your vet about running an Eliza test panel on the newbies, to test for Sendai, Myco, CARB, SDA and Rat Parvo Virus. This will let you know what you are deaking with. Rats who have both Myco and CARB tend to suffer more than rats with just Myco. Wtih a clean stress free environment Myco can be held at bay for a very long time.
