Acinetobacter baumannii is an opportunistic
nonfermentative, gram-negative, nonmotile, oxidasenegative
bacillus. The natural reservoir still remains to
be determined. However, it is found in many health care
environments and is a very effective human colonizer in
the hospital1. The combination of its environmental
resilience and its wide range of resistance determinants
renders it a successful nosocomial pathogen2. A.
baumannii is mostly a cause of septicaemia, pneumonia
and urinary tract infection following hospitalisation of
patients with more severe illness. A. baumannii is
frequently involved in numerous global outbreaks3,
occurring mostly in intensive care units4.
