The present study showed a trend of increasing prevalence of C indologenes infection after introduction of colistin and tigecycline usage. The bacteremia group had higher mortality rate than the pneumonia group. Increasing resistance to piperacillin-tazobactam, ceftazidime, cefepime, and newer fluoroquinolone were noticed in our analysis. Trimethoprim-sulfamethoxazole was a potential antimicrobial agent in vitro for C indologenes. To avoid collateral damage, we emphasize the importance of antibiotic stewardship program.

Corynebacterium striatum (C striatum) has been considered a contaminant of blood culture in past decades. Here we report the case of a patient with acute deterioration of chronic renal failure. She received hemodialysis and died from C striatum bacteremia. By using a randomly amplified polymorphic DNA (RAPD) method, we found that an association existed between C striatum from the bloodstream and that from the central venous catheter. We suggest that C striatum could be a pathogen of bloodstream infection in patients with such a catheter in place.

Pneumonia-related AB bacteremia has a worse outcome, more antibiotic resistance, and more comorbidity than the nonpneumonia group.

A woman aged 56 years of age had a community-acquired left neck abscess and internal jugular vein thrombosis with septicemia due to extended-spectrum β-lactamase (ESBL)-producing Klebsiella pneumoniae. Even though she was treated with intravenous meropenem, the bacteremia persisted. She was complicated with multiple brain abscesses, seizure, and leucopenia. After a combination of intravenous fosfomycin and meropenem, her clinical condition became stable. Combination treatment was continued for 2 months and she recovered. In individual cases of Lemierre syndrome with brain abscess caused by ESBL-producing Enterobacteriaceae, fosfomycin combination therapy may be the alternative choice.
