Background: Persistent Acinetobacter bereziniae bacteremia in a pregnant woman has not previously been reported.
Methods: A 25-year-old pregnant Kyrgyz woman developed a fever after McDonald operation. Serial blood cultures were performed.
Results: Multidrug-resistant Acinetobacter was isolated. She was prescribed meropenem. A. bereziniae was successfully identified by MALDI-TOF MS with an updated library, and 16S rRNA gene sequencing analysis supported the result.
Conclusions: The multidrug-resistant features of A. bereziniae and the therapeutic concentration of antibiotic agents during pregnancy had to be considered in the present case.
