Lodderomyces elongisporus causing catheter-related bloodstream infection and its biological characteristics / 中华检验医学杂志

ABSTRACT

In order to improve the laboratory identification ability of Lodderomyces elongisporus, we analyzed the main biological characteristics of Lodderomyces elongisporus isolated from peripheral venous blood and catheter blood of a brain stem infarction patient with a body temperature of 38.4 ℃, observed the colony color of the strain on CHROMagar Candida medium and the ascospores on Mcclary agar, identified the isolates with Vitek 2 compact, MALDI-TOF MS and sequence analysis, and tested the MICs with borth microdilution. The MICs of antifungal agents against Lodderomyces elongisporus are well below the normal values of these drugs. The central venous catheter was removed and antifungal drugs were used until two weeks after the last positive blood culture. During the medication perios, the blood culture was repeatedly negative, the patient had no fever and the infection index decreased to normal, which can be used for clinical reference.
