The full classification is: risk group = 1, note = "Animal classification RG: 1 - Security sensitive biological agent: No - Containment level: Containment Level 1 - Considerations for containment: This biological agent is capable of causing human and/or animal disease, but is unlikely to do so. Although it poses a low risk to the health of individuals or animals, and a low risk to public health or animal populations, this biological agent may cause opportunistic infections and may pose a threat to immunocompromised individuals or animals, or those with predisposing factors. Refer to the Canadian Biosafety Guideline on Containment Level 1: Physical Design and Operational Practices for recommended best practices for basic laboratory design and the safe handling of risk group 1 biological materials.". — The risk group for Germany has been imported on 2023-10-29. The full classification is: risk group = 1. — If in doubt, use the risk group given in the regulations for your country and, if these are not available, use the risk group given in the catalogue of the culture collection from which you have obtained or intend to obtain the strain.
