Newer options include tigecycline. Although not indicated specifically for Enterobacter pneumonia or bloodstream infections, tigecycline has excellent in vitro activity against these gram-negative bacilli. [22, 23, 24] In one laboratory study of multidrug-resistant gram-negative bacilli, tigecycline maintained a low MIC against all of the organisms. [25] Older options might include intravenous administration of polymyxin B or colistin, drugs that are rarely used, even in large medical centers, and for which standard susceptibility criteria are not available. A study of 89 carbapenem nonsusceptible Enterobacteriaceae isolates from China showed that polymyxin B was much more active than tigecycline. [26]
