Lab Diagnosis of Fungal Disease

Laboratory Diagnosis of Mucormycosis

Laboratory Diagnosis of Mucormycosis

Mucormycosis caused by Mucorales can be diagnosed by histopathological examination with or without isolation of the fungus from the same site.

Blastomyces dermatitidis: Pathogenesis, Lab Diagnosis

Blastomyces dermatitidis: Pathogenesis, Lab Diagnosis

Blastomyces dermatitidis is a thermally dimorphic fungus and causes blastomycosis. Single broad-based bud in a clinical sample is diagnostic.

Antigens in disease diagnosis

Antigens in disease diagnosis

Detection of specific antigens present in the sample (blood, urine, or CSF) using specific antibodies is the mainstay for the rapid diagnosis of infections.
