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.
雌性大鼠在妊娠早期接触涎泪腺炎后，其产仔率显著降低。8周及以上年龄的大鼠对接触感染高度敏感，体重增加明显减少，而5-6周龄的大鼠则具有抵抗力。
