Abstract

The Unusual Actinotigum schaalii (Formerly Named Actinobaculum schaalii) Bacteremia by Lu-Qing Zheng, Qing-Yong Wang

Background: This study aimed to evaluate unusual case reports about Actinotigum schaalii (A. schaalii) bacteremia patients in the past 20 years.
Methods: A retrospective review of A. schaalii bacteremia patients collected from MEDLINE between January 2005 and November 2024.
Results: Of 34 cases, the identification (ID) of A. schaalii for clinical samples included blood (n = 34), urine (n = 6), valve (n = 1), and biopsy (n = 1). Polymicrobial infections were 32.4% (n = 11 out of 34) in this study. Antimicrobial susceptibility tests (ASTs) were performed in most cases. The A. schaalii isolates were sensitive to penicillin, β-lactam combination agent, lincosamide, tetracycline, nitrofuran, cephem, carbapenem, oxazolidinone, ansamycin, macrolide, and glycylcycline; but resistant to fluoroquinolone, nitroimidazole, aminoglycoside, and folate pathway antagonists.
Conclusions: Microbiologists should perform the correct ID and suitable AST of the potentially invasive A. schaalii to help clinicians obtain the appropriate antimicrobial coverage for serious systemic infections.
