RESUMO
We report the first case of pelvic inflammatory disease (PID) caused by Actinobaculum massiliense. A 53-year-old woman attended the emergency department with symptoms compatible with a PID episode, finally resolved by intramuscular antibiotic treatment. Actinobaculum sp. was isolated by culture, and A. massiliense was confirmed by matrix assisted laser desorption time-of-flight mass spectrometry and 16S rRNA gene sequencing. Only a few cases of A. massiliense infections have been reported, and the pathogenesis of infections by these bacteria is poorly understood. The introduction of new diagnostic methods into hospital routines will improve the detection of new and little-studied pathogens.

Actinobaculum massiliense (Euzéby, 2006) was isolated from the urine of an elderly woman in 2001. Unfortunately, the strain deposited as the type strain was, by error, an Actinobaculum schaalii strain (Yassin et al., 2015). In 2015, we isolated a new strain of A. massiliense, FC3, from the urine of a 12-year-old patient with acute cystitis. We herein present the characteristics of strain FC3 (=CSUR P1982=DSM 100580) and formally propose it as the neotype strain of A. massiliense.
