A combined 678 bp sequence which containing promoter, initiation codon and NKND sequence can be used for further research of target antigen gene of pan species monoclonal antibody M26~32.

However, some notable improvements have been made in diagnostics with improved culturing methods, rapid species identification, and detection of fungemia with newer antigen assays.

A common genus antigen can be detected in disrupted virions of all species, but most species show no serological cross reactions.
