Abstract

Bifidobacterium breve is an anaerobic, gram-positive rod commonly found in the human intestinal microbiota. While rarely associated with bacteremia, most cases occur in neonates receiving B. breve-containing probiotics. Here, we report a rare case of B. breve bacteremia in an 80-year-old man presenting in cardiopulmonary arrest, despite not taking B. breve-containing probiotics. Blood cultures identified B. breve, and an 18-day course of antibiotics resolved the bacteremia. The rarity of adult cases may reflect age-related microbiota shifts and potential underdiagnosis due to the limited accuracy of rapid identification kits used in clinical practice.

一个老年男子与短双歧杆菌菌血症，一个罕见的条件在成人：一个病例报告。

短双歧杆菌是一种厌氧菌，革兰氏阳性杆状菌，常见于人类肠道微生物群。虽然很少与菌血症相关，但大多数病例发生在接受含有短芽孢杆菌的益生菌的新生儿中。在此，我们报告一例罕见的短芽孢杆菌菌血症，患者为80岁男性，尽管未服用含短芽孢杆菌的益生菌，但仍表现为心肺骤停。血液培养鉴定出短芽孢杆菌，18天的抗生素疗程解决了菌血症。成人病例的罕见性可能反映了与年龄相关的微生物群变化以及由于临床实践中使用的快速鉴定试剂盒的准确性有限而导致的潜在漏诊。

期刊介绍： Anaerobe is essential reading for those who wish to remain at the forefront of discoveries relating to life processes of strictly anaerobes. The journal is multi-disciplinary, and provides a unique forum for those investigating anaerobic organisms that cause infections in humans and animals, as well as anaerobes that play roles in microbiomes or environmental processes. Anaerobe publishes reviews, mini reviews, original research articles, notes and case reports. Relevant topics fall into the broad categories of anaerobes in human and animal diseases, anaerobes in the microbiome, anaerobes in the environment, diagnosis of anaerobes in clinical microbiology laboratories, molecular biology, genetics, pathogenesis, toxins and antibiotic susceptibility of anaerobic bacteria.
