Atypical Serological Response Marked by a Lack of Detectable Anti-gp43 Antibodies in a Patient with Disseminated Paracoccidioidomycosis

摘要

Serological tests are frequently used to diagnosis paracoccidioidomycosis. A glycoprotein of 43 kDa is considered to be the main diagnostic antigen, being recognized by virtually all patients' sera. A case of atypical serological response, consisting of a lack of detectable anti-gp43 antibodies, in a patient with disseminated paracoccidioidomycosis is presented.
