OXA-58 is a recently described carbapenemase from Acinetobacter spp. in Europe. We examined earlier worldwide Acinetobacter collections and found bla(OXA-58) in 30 carbapenem-nonsusceptible isolates, including several isolates collected in Argentina and Kuwait in 1995 and 1996 and in a British outbreak strain from 2000. Most isolates (28 of 30) also had bla(OXA-51). We conclude that bla(OXA-58) is geographically widespread and has occurred in Acinetobacter spp. for over 10 years.
