Coloured scanning electron micrograph (SEM) of Multi-drug resistant Acinetobacter baumannii (MDR-AB). A. baumanii is a Gram-negative, MDR-AB, oxidase negative, aerobic, coccobacillus prokaryote (bacterium). This strain is multi-drug resistant and causes various nosocomial infections, including, skin and wound infections, pneumonia, meningitis, septicaemia, urinary tract infection and endocarditis. It is commonly found in soil, water, sewage, animals, and the normal skin and gastrointestinal tract of patients and health care workers. A. baumannii has always been naturally resistant to multiple antibiotics. It can be especially resistant to penicillin and chloramphenicol. It is the most frequently encountered species in the clinical laboratory and can be linked to many hospital acquired infections. Species found in soil can colonize root nodule systems and oxidize the hydrogen produced by nitrogen fixing bacteria. Magnification: x2,200 when shortest.
