PASTEURELLA-MULTOCIDA ISOLATION FROM A TUBOOVARIAN ABSCESS - A CASE-REPORT

BACKGROUND: Human infection with Pasteurella multocida occurs most commonly following a nonhuman animal bite wound or cat scratch, with local skin and soft tissue infections the most frequent posttraumumatic manifestations. Genitourinary tuner pathology attributable to this organism occurs infrequently, with only one previous reported case of P multocida infection presenting in the form of a tuboovarian abscess. CASE: A 44-year-old woman with an acute abdomen underwent exploratory laparotomy, revealing a right-sided tuboovarian abscess. Following a total abdominal hysterectomy and bilateral salpingo-oophorectomy with a seven-day postoperative course of intravenous metronidazole, ampicillin and gentamicin, the patient was sent home on a regimen of cephradine, only to return with sepsis three days later. A course of intravenous aqueous penicillin sodium, metronidazole and cefotaxime was administered for the treatment of P multocida sepsis since this organism was identified in the intraoperative pelvic fluid culture 24 hours after the patient's initial discharge. After 13 days of the above regimen, the patient achieved full defervescence and was discharged on hospital day 15. CONCLUSION: In the setting of a tuboovarian abscess, the clinician should consider P multocida as a potential etiologic agent, especially in a patient with extensive exposure to nonhuman animals. In the treatment of an acute adnexal infection-E secondary to this organism, one should employ perioperative therapy with the appropriate antibiotics for a duration of at least 14 days.
