Eight phenotypically identified as C. amycolatum were identified as C. xerosis by MicroSeq, 1 C. glucuronolyticum was identified as C. seminale, 1 C. pseudodiphtheriticum isolate was identified as C. pseudotuberculosis, 1 C. minutissimum isolate was identified as C. xerosis, 1 C. afermentans isolate was identified as C. urealyticum, 1 CDC group G isolate was identified as C. tuberculostearicum, 1 C. striatum isolate was identified as C. minutissimum, and 1 C. imitans isolate was identified as C. xerosis.
