Motile gram-negative aerobic bacteria, plump-shaped rods, with polar flagella which have an important role in pathogenicity, non-spore forming
Pneumonia, bacteremia, wound infections, urinary tract infections, swimmer's ear, eye infections related to use of contact lenses.
Health Hazards
Host Range
Humans, Animals, Plants
Modes of Transmission
Direct contact by inhalation of aerosols. Direct contact by aspiration of contaminated water (tap or distilled). Direct contact by exposure of wounds to contaminated materials. Indirectly by contact of mucous membranes with discharges from infected conjunctivae or infected respiratory secretions.
Signs and Symptoms
Conjunctivitis, Upper Respiratory Infections, Pneumonia, Urinary Tract Infections, Wound Infection.
Infectious Dose
Incubation Period
Variable depending on infection. Eye infection is 24 to 72 hours.
Medical Precautions/Treatment
Antibiotic Prophylaxis
None available
Aggressive antibiotic therapy for severe infections; Local application of antibiotic ointment or drops for skin or eye infections. Pseudomonas aeruginosa is intrinsically resistant to many common antibiotics.
Bacteriological identification of infection.
MSU Requirements
Report any exposures
Laboratory Hazards
Laboratory Acquired Infections (LAIs)
None reported to date. However, this is an opportunistic pathogen and there is the possibility of severe to fatal infection in the immunocompromised.
Clinical Specimen: Respiratory secretions, wound exudates, blood, urine. Environmental Reservoir: Water, infected solutions (IV, disinfectants, soap). Cultures, frozen stocks, other samples described in IBC protocol.

Risk Group & Containment Requirements
Risk Group 2

Agents that are associated with human disease which is rarely serious and for which preventive or therapeutic interventions are often available.

For all procedures involving suspected or known infectious specimen or cultures.
For all procedures utilizing infected animals.
Spill Procedures
Notify others working in the lab. Remove PPE and don new PPE. Cover area of the spill with absorbent material and add fresh 1:10 bleach:water. Allow 20 munutes (or as directed) of contact time. After 20 minutes, cleanup and dispose of materials.
  • Immediately notify all personnel in the lab and clear all personnel from the area. Remove any contaminated PPE/clothing and leave the lab. 
  • Secure the area by locking doors, posting signage and guarding the area to keep people out of the space. 
For assistance, contact MSU's Biosafety Officer (406-994-6733) or Safety and Risk Management (406-994-2711).
Exposure Procedures
Mucous membrane
Flush eyes, mouth, or nose for 5 minutes at eyewash station.
Other Exposures
Wash area with soap and water for 5 minutes.
Immediately report incident to supervisor, complete a First Report of Injury form, and submit to Safety and Risk Management.
