Use of the Coccidioides posadasii Δchs5 Strain for Quality Control in the ACCUPROBE Culture Identification Test for Coccidioides immitis

摘要

Coccidioides posadasii Δchs5 is a strain that is excluded from the select agent list. Sixteen assays using test reagents from three different ACCUPROBE Coccidioides immitis culture identification test lots had an average of 132,998 relative light units (RLU), which is well beyond the 50,000-RLU positive cutoff value for the test. Coccidioides posadasii Δchs5 is a satisfactory quality control isolate in the ACCUPROBE culture identification test for Coccidioides immitis.
