With the increasing number of prosthetic joints replaced annually worldwide, orthopedic implant-associated infections (OIAI) present a considerable burden. Accurate diagnostics are required to optimize surgical and antimicrobial therapy. Sonication fluid cultures have been shown in multiple studies to improve the microbiological yield of OIAIs, but uptake of sonication has not been widespread in many routine clinical microbiology laboratories. In this issue, M. Dudareva and colleagues (J Clin Microbiol 56:e00688-18, 2018, https://doi.org/10.1128/JCM.00688-18) describe their unit's experience with OIAI diagnosis using periprosthetic tissue inoculated into an automated blood culture system and sonication fluid culture.
随着全球每年更换的假体关节数量不断增加,与骨科植入物相关的感染(OIAI)带来了相当大的负担。需要准确的诊断来优化手术和抗菌治疗。多项研究表明,超声液培养可提高 OIAI 的微生物学产量,但在许多常规临床微生物学实验室中,超声技术的应用并未广泛普及。在本期杂志中,M. Dudareva 及其同事(J Clin Microbiol 56:e00688-18, 2018, https://doi.org/10.1128/JCM.00688-18)描述了他们单位使用经皮假体组织接种到自动血液培养系统和超声液培养中进行 OIAI 诊断的经验。
