Acinetobacter is an aerobic, gram-negative bacteria typically found in water sources in soil. Although it has a very low virulence, acinetobacter can flourish in organ systems which contain a high level of fluid, such as respiratory secretions, urine, and in rare cases synovial fluid post-operatively. Most isolates represent colonization rather than infection.[1]
Pathophysiology
Acinetobacter species are non-motile bacteria which appear as gram-negative coccobaccili in pairs on microscopic study. There are 25 different strains[2], though A. Baumanni is responsible for 80% of infections. All species are classified as non-lactose fermenting.
Clinical significance
Acinetobacter causes a variety of diseases, ranging from nosocomial (hospital-aquired) pneumonia to serious wound infections. Symptoms of a wound infection include redness and/or heat at the site, fever, chills, purulent or odd-colored drainage, and pain. Although not prevolent in the general population, Acinetobacter can cause severe, life-threatening illness in immunocompromised patients.[3]
