Document Summary
Majority of lab errors and hazard is human error (65%: e. coli k-12- genetically modified lab strain, no fimbriae, altered o-antigen, no capsular. Infectious dose- the number of microorganisms required to initiate an infection: method of transmission. Direct contact: direct transmission to receptive portal of entry. Indirect contact: vehicle-borne, such as inanimate materials or objects (fomites). Airborne: dissemination of microbial aerosols to a suitable portal of entry, routes of transmission. Community risk: low: risk group 2 (can cause disease, unlikely to be serious) Community risk: low: risk group 3 (can be serious, does not ordinarily spread from person to person, Effective treatment and preventative measures are usually available) Community risk: low: risk group 4 (likely to cause serious or lethal disease, can be easily transmitted from one to aother, effective and preventative treatment not usually available) Host range (who it infects): human (healthy adult) and animals.
