| Abstract |
A 28-year-old woman presented with an abdominal distention and was diagnosed with ovarian cancer with multiple metastases. The patient underwent total abdominal hysterectomy, pelvic lymphadenectomy, and had drainage tubes placed bilaterally in the retroperitoneal space. On postoperative day 5, she developed a fever, leading to a suspicion of surgical site infection. Consequently, blood and drain cultures were collected. On postoperative day 11, Metamycoplasma hominis was identified in the drain culture, but not in the initial blood cultures. However, M. hominis was detected in the blood culture after extending the incubation period and conducting subcultures.
The role of blood cultures in diagnosing M. hominis is critical for distinguishing between colonization and true infection. However, because of its microbiological characteristics, such as a lack of CO2 production and prolonged culture periods, blood culture systems occasionally yield false-negative results. Therefore, in cases of suspected M. hominis infection, it is important to share clinical and culture information between the microbiological laboratory and the physician to determine appropriate culture method and incubation duration. |
