Tigecycline is a new broad spectrum antibiotic that is predominantly used for the treatment of severe infections both in critically ill patients admitted to the ICU and in non-ICU patients with less severe clinical conditions. ⋯ The patient that receives tigecycline in the ICU has a higher severity level and worse clinical outcome than the non-ICU patient treated with this antibiotic. It is necessary to optimize the indications of tigecycline in the ICU to improve the clinical results.

Acinetobacter baumannii are emerging as the causal agents of healthcare-associated infections. We describe arenal transplant recipient who developed bacteremia caused by multiresistant A. baumannii, which received a combination of tigecycline, colistin, and meropenem in continuous infusion. The clinical outcome was favorable. ⋯ Our analysis reveals the presence of abla-OXA-72 gene,a class D of oxacillinase belonging to bla-OXA-40-like group,which constitutes the most disseminated familiy of carbapenemases in Spain. Thus, we found different susceptibility patterns of A. baumannii when we used different Mueller-Hinton agars with different manganese concentrations. Lastly, we explain the combination of these three antibiotics administered to increase microbiologic and pharmacodynamic yield.
