Acinetobacter spp are aerobic gram-negative coccobacillus with preference for warm, ambient environments, which have received a great interest during the last two decades due to its ability to accumulate, with multiple mechanisms, multi-drug resistance stains. As a result these bacteria have become, a sometimes lethal, etiologic factor mainly in intensive care unit (ICU) infections, ventilator associated pneumonia (VAP), and in communityacquired infections and represent an emergent public health problem [1, 2] .
