Detection of circulating antibodies in patients affected by chromoblastomycosis by Cladosporium carrionii using double immunodiffusion.

The antibodies in sera of patients affected by Chromoblastomycosis are detected using the technique of double immunodiffusion and the mycelial somatic antigens and the culture filtrates antigens of Cladosporium carrionii. From the 13 sera tested 8 have given positive results. The fresh serum from a patient under treatment gives 2 bands, while fresh serum from a non-treated patient gives 3 bands.
