Signs and Symptoms   Causes a variety of diseases ranging from pneumonia to serious blood or wound infections
Infectious Dose  Unknown.
Incubation Period   Unknown.
Medical Precautions/Treatment
None available.
None available.
Treatment Treatment with imipenem or meropenem, but a steady rise in carbapenem resistance has been reported. Consequently, treatment methods often fall on polymyxins, such as colistin.
Monitor for symptoms of infection.
MSU Requirements
Report any exposures.
Laboratory Hazards
Laboratory Acquired Infections (LAIs)
None have been reported.
