[A urinary outbreak of Acinetobacter baumanii in a spinal cord injury unit].
From January 1990 to April 1992, 114 urinary strains of Acinetobacter baumanii were isolated in 57 patients with traumatic spinal cord [correction of medular] injury. The strains were characterized by having all of them the same biochemical identification, except for citrate, maltose and tryptophan-desaminase. Until December 1990, (5 strains) were resistant to all antibiotics, except to tobramicine, amikacine, cotrimoxazol and imipenem (6.3%, 33.9%, 26.7% and 0% of resistances, respectively); since January 1991, (99 strains) became resistant to all of them, except to imipenem. 39.5% of AB were isolated in pure cultures, 46% of them with pyuria. Between February 1991 and January 1992, we observed the highest number of affected patients, although without seasonal predominance. We observed as well a higher incidence among males (46 males, 11 females). 80% of them carried a permanent probe. Only 6 patients presented clinical signs directly related to AB. The environmental study could not demonstrate any source of contagion or transmission mechanism.
