2 pox outbreaks among white rats in a breeding colony are described. The infection occurred in 3 different forms: pulmonary, dermal and mixed. Apparently healthy animals appeared to be virus carriers. The virus isolated belonged to the genus Orthopoxvirus of Poxviridae family, and was very close to cowpox virus. It differed from reference strains of cowpox virus in having a lower ceiling temperature and a higher pathogenicity for white rats.
