Case report of bacteremia that progressed from an operation scar infection of M. hominis after Caesarean section in a 33-year-old woman

Abstract

Mycoplasma hominis is a microbe existing at vagina of almost 50% of reproductive women. It happens to infect genitourinary tract or uterine muscular wound of Caesarean section. M. hominis is Gram-negative and its isolation needs prolonged incubation in routine blood culture. M. hominis is resistant to β-lactam antibiotics because it lacks a cell wall. No response to these antibiotics results in more serious symptoms than other bacteria. We report a case of bacteremia that progressed from postpartum endometritis with M. hominis after cesarean section in a 33-year-old woman. Magnetic resonance imaging was suspicious for an abscess at the surgical site at seven days after cesarean section, and reoperation was undertaken at the same time. Although we provided an intraperitoneal drainage tube for withdrawing liquids from the vesicouterine excavation during reoperation, and treated her with several antimicrobial agents, her bacteremia symptoms persisted. At 15 days after cesarean section (day seven of reoperation), M. hominis was considered to be the primary causative organism. The clinical symptoms have improved by the 11th day of re-operation after administration of levofloxacin sensitive to M. hominis.[Adv Obstet Gynecol, 69 (1) : 26-31, 2017 (H29.2)]
