Categories of Hazardous Microorganisms
The CCM classified its strains according to international standards in one of the following hazard groups.
Biohazard group: 1 - microorganisms that are unlike to cause human or animal diseases. They are distributed without restrictions to medical, veterinary, research, teaching or industrial institutions and they can be handled accordingto good laboratory practice.
Biohazard group: 2 - microorganisms that may cause human and/or animal diseases and which might be a hazard to laboratory workers, but are unlike to spread in the community. Laboratory exposure rarely produces infection and effective prophylaxis or effective treatment is available.
Biohazard group: 3 - microorganisms that may cause severe human and/or animal diseases. They present a serious hazard to laboratory workers and/or a risk of spreading in the community. There is usually no sufficient prophylaxis and treatment.
Biohazard group: 4 - microorganisms that cause severe human diseases and are serious hazard to laboratory workers. They may present a high risk of spread in the community and there is usually no effective prophylaxis or treatment.
No microorganisms of Biohazard group 3 and 4 are maintained in the CCM.
