is a gram-positive bacillus that causes food poisoning. Listeriosis causes gastrointestinal infections and occasionally leads to fatal bacteremia in older adults. The symptoms of infections are non-specific and difficult to diagnose. We describe a case of bacteremia in an 82-year-old Japanese woman who had handled raw venison one month prior to becoming ill, but had not consumed any. No other possible sources of infection were identified. She presented with a fever without any focal symptoms. Computed tomography revealed enteritis with mucosal damage. Blood culture revealed bacteria with gram-positive rod morphology, that were confirmed as using mass spectrometry. The patient was treated with intravenous ampicillin and made a full recovery. This case illustrates the virulence of , which can cause bacteremia from handling contaminated food, even without consumption.
是一种导致食物中毒的革兰氏阳性杆菌。李斯特菌病会引起胃肠道感染，偶尔会导致老年人出现致命的菌血症。感染症状不具特异性，难以诊断。我们描述了一例82岁日本女性菌血症病例，该女性在发病前一个月处理过生鹿肉，但未食用。未发现其他可能的感染源。她出现发热，无任何局部症状。计算机断层扫描显示有黏膜损伤的肠炎。血培养发现革兰氏阳性杆菌形态的细菌，通过质谱法确认为[具体细菌名称未给出]。患者接受静脉注射氨苄青霉素治疗后完全康复。该病例说明了[具体细菌名称未给出]的毒力，即使不食用受污染食物，仅通过处理也可能导致菌血症。
