Helicobacter species can be found in a wide variety of animals and remain common contaminants of laboratory rodents. Fostering of neonatal pups has been used to eliminate Helicobacter spp. from various laboratory rodents, including laboratory mice and gerbils. Deer mice (Peromyscus maniculatus) from a captive colony enzootic for at least one Helicobacter species were mated, and the pups produced were fostered on laboratory mice 24 h after birth. After 2 rounds of fostering, both foster dams and pups were free of Helicobacter spp. as determined by fecal PCR analysis. Removal of Helicobacter infection through neonatal fostering has not been described previously for Peromyscus maniculatus.
