title: Infectious sialodacryoadenitis and rat breeding.
abstract: The littering rate of female rats was significantly lowered when they had been exposed to sialodacryoadenitis early in pregnancy. Rats of 8 weeks or more of age were highly susceptible to contact infection, showing marked decrease in bodyweight gain, whereas those of 5-6 weeks of age were resistant.
