General Information: Soil bacterium that can cause opportunistic infections. Ochrobactrum anthropi is an opportunistic human pathogen usually causing infection in association with indwelling medical devices, such as catheters and drainage tubes. This organism and related species have also been isolated from soil, activated sludge, and plants. Ochrobactrum anthropi is a Gram-negative, anaerobic, motile bacterium. A common soil bacteria, it was originally considered as an opportunistic pathogen, causing infections in immunocompromised patients, patients with indwelling catheters or peritoneal dialysis but it is now emerging as a more and more important nosocomial pathogen. The first case of human infection was described in 1980. It has been isolated from blood, the urogenital tract, respiratory tract and eyes, and it can be part of the normal intestinal flora. It is resistant to many antibiotics, especially the beta-lactams.
