Abstract

Eggerthella lenta is an obligate anaerobic, Gram-positive bacilli, belonging to the human microbiota of gastrointestinal and female reproductive tracts, oral cavity and prostate gland. In this article, we aim to describe clinical and microbiological characteristics of seven E. lenta strains causing bacteremia. We conducted a descriptive retrospective study including all E. lenta strains causing bacteremia, from February 2019 to August 2023 at the Basurto University Hospital. Seven patients were included in the study with a mean age of 72.7 years. Six patients presented risk factors associated with bacterial infections. All patients were admitted to the hospital because of suspicious of bloodstream infection associated with abdominal symptoms for intravenous antibiotic treatment. Four E. lenta isolates were resistant to penicillin, while all isolates presented high MICs to piperacillin/tazobactam and low MICs to amoxicillin/clavulanic acid. All patients recovered without no complications.

引起菌血症的 Eggerthella lenta 的临床和微生物学特征

连塔卵球菌（Eggerthella lenta）是一种厌氧革兰阳性杆菌，属于人类胃肠道、女性生殖道、口腔和前列腺微生物群。本文旨在描述引起菌血症的 7 株伦他大肠杆菌的临床和微生物学特征。我们开展了一项描述性回顾研究，其中包括 2019 年 2 月至 2023 年 8 月期间在巴苏托大学医院引起菌血症的所有连塔菌菌株。研究共纳入七名患者，平均年龄为 72.7 岁。六名患者存在与细菌感染相关的风险因素。所有患者均因怀疑血流感染并伴有腹部症状而入院接受静脉抗生素治疗。4 例伦他大肠杆菌分离株对青霉素耐药，所有分离株对哌拉西林/他唑巴坦的 MIC 值较高，对阿莫西林/克拉维酸的 MIC 值较低。所有患者均已康复，未出现并发症。

期刊介绍： Hoy está universalmente reconocida la renovada y creciente importancia de la patología infecciosa: aparición de nuevos agentes patógenos, de cepas resistentes, de procesos con expresión clínica hasta ahora desconocida, de cuadros de una gran complejidad. Paralelamente, la Microbiología y la Infectología Clínicas han experimentado un gran desarrollo como respuesta al reto planteado por la actual patología infecciosa. Enfermedades Infecciosas y Microbiología Clínica es la Publicación Oficial de la Sociedad Española SEIMC. Cumple con la garantía científica de esta Sociedad, la doble función de difundir trabajos de investigación, tanto clínicos como microbiológicos, referidos a la patología infecciosa, y contribuye a la formación continuada de los interesados en aquella patología mediante artículos orientados a ese fin y elaborados por autores de la mayor calificación invitados por la revista.
