Objective A sterile golden hamster model was established by cesarean section purification. Methods SPF-grade donor female golden hamsters were selected, and males and females were mated 1 ∶ 1 and separated after mating. The cage time of the surrogate mothers was 1 week earlier than that of the donor mothers. Parturient golden hamsters underwent hysterectomy on a sterilized workbench, and the uteruses were transferred into isolation kits and stripped. To obtain sterile milk for milk replacement, sterile ICR mice and sterile SD rats were used. After successful separation, the hamsters were transferred to isolation kits to prepare for feeding. The sterility status of the feeding isolation kits was tested monthly. Results Three caesarean sections were performed, but the first and second lactations failed. The third milk replacement was successful, and 18 young hamsters were obtained with survival rates of 88% and 66% after weaning. All hamsters were quality tested by GB / T 14926. 41-2001. Conclusions Using a cesarean section purification technique and sterile ICR mice and SD rats for microbial-free milk replacement, a sterile golden hamster model was obtained.
