“…Aminoglycosides, for instance, presented susceptibilities rates ranging from 31.8% to tobramycin to only 9.3% to amikacin. Despite the controversies, tigecycline can be considered one of the few therapeutic options for treatment of MDR infection in skin and soft tissue infections and meningitis (Montravers et al, 2013; Kooli et al, 2016; Lauretti et al, 2017). Still tigecycline is not recommended for the treatment of ventilator-associated pneumonia and BSI (http://www.fda.gov/drugs/drugsafety/ucm224370.htm), we evaluate the tigecycline activity in our BSI isolates with surveillance purposes and no resistance was observed, even this phenotype becomes progressively more common in A. baumannii in several countries (Navon-Venezia et al, 2007; Al-Sweih et al, 2011; Montravers et al, 2013; Sun et al, 2013; Provasi Cardoso et al, 2016; Vasconcellos et al, 2017a; Royer et al, 2018).…”
