Abstract Background: Candida species are harmless commensals of hosts, including humans, but they can cause infection when the immune system is compromised. Infections with non-albicans species can occur, ranging from urinary tract infections to sepsis, especially among patients in intensive care units. Case: The patient, a 37-year-old woman, presented with severe abdominal pain, fever, and vomiting. The patient’s symptoms and fever continued in spite of treatment with antibiotics, and she underwent exploratory laparotomy. Cyst content culture results showed that Candida kefyr was present in the cyst. Conclusion: To the best of our knowledge, this is the first case report of a tubo-ovarian abscess caused by C. kefyr. Rare pathogens can be found in patients with a tubo-ovarian abscess, so culture of the abscess material is important for determining subsequent treatment, particularly in women who require an operation for tubo-ovarian abscess.
Résumé Contexte : Les espèces de Candida sont des organismes commensaux sans danger pour leurs hôtes, y compris pour les humains, mais elles peuvent causer des infections quand le système immunitaire est compromis. Des infections aux espèces non albicans peuvent survenir (allant de l’infection urinaire à la septicémie), surtout chez les patients dans les services de soins intensifs. Cas : La patiente, une femme de 37 ans, s’est présentée avec des douleurs abdominales intenses, de la fièvre et des vomissements. Ses symptômes et sa fièvre ont persisté malgré le traitement antibiotique, et elle a subi une laparotomie exploratoire. Les résultats de culture du contenu d’un kyste ont montré la présence de Candida kefyr dans celui-ci. Conclusion : À notre connaissance, il s’agit du premier cas rapporté d’abcès ovario-tubaire causé par C. kefyr. Comme des pathogènes rares peuvent être trouvés chez les patientes ayant un abcès ovario-tubaire, la culture du contenu de l’abcès est importante pour déterminer le traitement subséquent, surtout chez les femmes qui ont besoin d’une chirurgie.

INTRODUCTION
A
tubo-ovarian abscess (TOA) is an inflammatory mass located among the fallopian tube, ovary, bowel, and bladder. Some case reports have highlighted Candida spp., Pasteurella multocida, Salmonella spp., and Streptococcus pneumoniae as rare potential pathogenic causes of TOAs.1–3 Here, we present a case report of a patient with a TOA caused by Candida kefyr. To the best of our knowledge, this is the first report of a TOA caused by C. kefyr. THE CASE
The patient, a 37-year-old woman, gravida 2 para 1, presented to the emergency department with severe abdominal pain, fever, and vomiting. Physical examination showed that her blood pressure was 119/69 mm Hg, pulse rate was 116 beats per minute, and axillary temperature was 39.3°C. On abdominal examination, a palpable, mobile, pelvic mass was noted in the left lower quadrant. On gynaecological examination, purulent endocervical discharge, cervical motion, and uterine and adnexal tenderness were observed. Transabdominal ultrasonography revealed a multilobular cyst 10 cm in diameter. White blood cell count was 25 000 mm3, and C- reactive protein was 29.34 mg/dL. The serum level of CA 125 was 138 (normal range <35). Computed tomography revealed a bilateral, multilobular, enhanced wall, 10 × 5 cm diameter cyst with an appearance compatible with that of an abscess (Figure). Administration of ceftriaxone (1 g intravenously every 12 hours), metronidazole (500 mg intravenously every 8 hours), and doxycycline (100 mg orally every 12 hours) was started for initial therapy. However, the patient’s complaints and the fever continued in spite of the antibiotics. The patient underwent an exploratory laparotomy, which revealed a TOA

organic dairy products during her pregnancy. After finding C. kefyr sepsis in the preterm newborns, these investigators recommended that the consumption of organic dairy products during pregnancy should be considered.12 Our patient had started to consume organic unpasteurized dairy products 3 months before her signs and symptoms began. CONCLUSION
Culture of abscess material is important for determining subsequent treatment, particularly for patients who undergo an operation for TOA. Especially for patients with hematologic malignant diseases, risk factors for immunosuppression, or inadequate response to antibiotic therapy, Candida species and the addition of antifungals to the treatment regimen should be considered. with a 15-cm diameter on the pouch of Douglas between the bilateral tube and the ovary, uterus, and sigmoid colon, with dense adhesions. Cystectomy and right salpingectomy were performed. Cyst content culture results showed that the cyst contained C. kefyr. Administration of fluconazole (400 mg intravenously every 24 hours) was started and continued for 14 days. The patient’s condition improved, and fever was not observed during the course of antifungal therapy. Pathologic examination confirmed the diagnosis of a TOA. There were no associated complications, and the patient was discharged 2 weeks after the operation. DISCUSSION
C. kefyr, formerly known as Candida pseudotropicalis, is an opportunistic pathogen that can be isolated from dairy products and rarely causes systemic infection in humans.4 The first report in the literature of C. kefyr as a pathogen was in 1969 for a patient with cystitis caused by this organism.5 C. kefyr forms flat, soft, and yellowish colonies on Sabouraud dextrose agar medium and does not form colonies on Sabouraud medium containing meat juice.6 To the best our knowledge, this is the first case report of a TOA caused by C. kefyr. Sendid et al. reported that C. kefyr was isolated twice as frequently from patients in oncohematology units than from patients in other units.7 In the literature, there are four case reports of TOAs from which Candida species were isolated.8–11 Pineda et al.12 reported chorioamnionitis and sepsis caused by C. kefyr in a woman pregnant with twins who had regularly consumed
