Abstract：
Abiotrophia defectiva is a pathogen of the oral, gastrointestinal, and urinary tracts that can cause significant systemic disease with uniquely negative blood cultures depending on the growth medium. Prior cases note possible seeding from relatively common procedures such as routine dental work and prostate biopsies, however case literature describes prior infectious complications to include infective endocarditis, brain abscess formation, and spondylodiscitis. While prior cases describe some aspects of these presentations, we highlight a case of a 64-year-old male who presented to the emergency department (ED) f5or acute onset of low back pain with fever symptoms four days after an outpatient transrectal ultrasound-guided needle biopsy of the prostate, with a prior dental extraction described four weeks prior to arrival. Findings on initial ED presentation and subsequent hospitalization revealed infective spondylodiscitis, endocarditis, and brain abscess formation. This is the only cases noted in literature with all three infection locations with dual risk factors of dental and prostate procedures prior to symptom onset. This case highlights the multifocal illness that can complicate Abiotrophia defectiva infections, and the importance of thorough ED evaluation and multiservice approach for consultation and treatment.
摘要：
营养不良是口腔的病原体，胃肠,和尿路，可导致明显的全身性疾病，血液培养独特阴性，取决于生长培养基。先前病例注意到可能来自相对常见的程序，如常规牙科工作和前列腺活检，然而，病例文献描述了先前的感染性并发症，包括感染性心内膜炎，脑脓肿形成,和脊椎盘炎.虽然先前的案例描述了这些演示的某些方面，我们重点介绍了一例64岁的男性，他在门诊经直肠超声引导下前列腺穿刺活检后四天出现急性腰背痛并伴有发烧症状，在抵达前四周描述了一次拔牙。最初的ED表现和随后的住院发现感染性脊椎盘炎，心内膜炎,脑脓肿的形成.这是文献中提到的唯一病例，在症状发作之前，所有三个感染部位均具有牙科和前列腺手术的双重危险因素。这个病例突出了多灶性疾病，它可以使无生物素化脓感染复杂化，以及全面的ED评估和多服务方法对咨询和治疗的重要性。
