초록
Lactococcus속은 조건무산소성 그람양성알균으로 catalase 음성, 비운동성이며 10∼40°C에서 배양된다. Lactococcus속은 16개의 종으로 구성되어 있으며, 그 중 Lactococcus garvieae와 Lactococcus lactis가 인간질병에 주로 관여하는것으로 알려져 있다. 본 연구는 발열, 구토, 옆구리 통증으로 내원한 74세 여자의 소변 배양에서 Lactococcus garvieae가 배양된 사례를 최초 보고한다. 상기 환자는 의료기관에서 시행한혈액검사, 미생물 배양검사, 컴퓨터단층촬영 등의 검사를 통해급성 요로감염의 소견을 확인하였다. 신장내과 병동에 입원 후수액처치 및 에리스로마이신 항생제 치료를 시행하였고 5일 후환자는 퇴원하였다. 본 증례는 우리나라에서 처음으로 요로감염 환자의 소변에서 L. garvieae가 분리된 사례로서 향후 L. garvieae 감염 환자의 치료에 도움이 될 것이다.
Abstract
The genus Lactococcus is a gram-positive, catalase-negative, non-motile bacterium. It is a facultative anaerobe and can be cultured at 10∼40°C. The genus Lactococcus consists of 16 species, of which Lactococcus garvieae and Lactococcus lactis are known to cause disease in humans. This study reports the first case in which L. garvieae was identified in the urine culture of a 74-year-old woman. The patient confirmed the findings of acute urinary tract infection through blood tests, microbial identification tests, antibiotic susceptibility tests, and computed tomography performed at a hospital. The patient was admitted to the nephrology ward and was treated with IV fluids and erythromycin antibiotics and discharged 5 days later. This is the first case in Korea in which L. garvieae was isolated from the urine of a patient with a urinary tract infection and is expected to be useful in treating patients with L. garvieae infection in the future.
