Aerobic, non-fermentative bacteria that occur widely in water, soil and living organisms.
They occur naturally on the human skin but can cause disease, especially through
open wounds contaminated by soil. This has been a problem in war situations
where these types of wounds occur. Acinetobacter species also exist in hospitals
where they can be a source of infection for patients with low disease resistance
thresholds. In general, Acinetobacter species do not cause disease in
healthy individuals but in immunocompromised patients they can cause pneumonia,
meningitis, bacteremia (bacteria in the blood), and skin and wound infections.
