Abstract
We identified three encapsulated Bacillus cereus strains, isolated from patients with severe pneumonia, in a collection of B. cereus isolates associated with human illness. We found that the extent of capsule expression was influenced by culturing conditions. Our findings highlight consequent clinical and laboratory diagnostic challenges posed by such isolates.
摘要
我们在一批与人类疾病相关的蜡样芽孢杆菌分离株中，鉴定出了三株从重症肺炎患者体内分离出的包膜蜡样芽孢杆菌菌株。我们发现，包膜表达的程度受培养条件影响。我们的研究结果凸显了此类分离株给临床和实验室诊断带来的后续挑战。
