Acinetobacter naumannii has emerged in the last decades as a major cause of healthcare-associated infection and nosocominal outbreaks. A baumanii blood infections (AbBI) are associated with significant ICU related mortality. Aguirre-Avalos and co-workers determined the sevarity and course of AbBI in an ICU of a medical care facility. Of the 46 patients identified with AbBI, 31 patients displayed blood infection by A. baumannii. The researchers found that the median time for the acquisition of AbBI was 9+7 days. The major symtoms of the 31 patients were- septic shock (42%), severe sepsis (42%) and sepsis (31%). The results showed that a significant proportion of the A. baumannii isoltes were resistant to inipenem. A high patient mortality was associated with AbBI (45%) alone. In addition about 40% of the patients died due to polymicrobial blood infaction. About 70% of the patients died during the first 72 hours of AbBI due to septic shock. The reseaechers concluded that AbBI displayed an endemic presentation dueing the study. It is associated with a significant increase in death rate of ICU patients.
