Cross-reactivity of the PLATELIA CANDIDA antigen detection enzyme immunoassay with fungal antigen extracts.
We studied the specificity of the PLATELIA CANDIDA Ag enzyme immunoassay by using 130 isolates of 63 clinically relevant fungal species. Antigen extracts of seven Candida spp. (Candida albicans, C. dubliniensis, C. famata, C. glabrata, C. guilliermondii, C. lusitaniae, and C. tropicalis) repeatedly yielded positive reactions (>0.5 ng/ml). Geotrichum candidum and Fusarium verticillioides were fo...
متن کاملDetection of poliovirus antigen by enzyme immunoassay.
A solid-phase enzyme immunoassay (EIA) was developed for the detection of poliovirus antigen. Rabbit and guinea pig antisera for the assay were raised against purified poliovirus type 3/Fin (strain 3/Fin/K) isolated from a fecal specimen from a meningitis patient during an outbreak of poliomyelitis in Finland in 1984. The EIA was highly specific for poliovirus type 3, and it was about 30 times ...
متن کاملCross-reactivity in the Platelia™ Aspergillus enzyme immunoassay caused by blastomycosis.
It is well known that cross reactions with other fungal pathogens including Histoplasma capsulatum can occur with the use of the Platelia™ Aspergillus galactomannan assay. We report two patients with confirmed blastomycosis whose bronchoalveolar lavage (BAL) fluid tested positive for Aspergillus galactomannan despite no evidence of aspergillosis.
متن کاملPerformance characteristics of the platelia Aspergillus enzyme immunoassay for detection of Aspergillus galactomannan antigen in bronchoalveolar lavage fluid.
We have evaluated the Platelia Aspergillus enzyme immunoassay for detection of galactomannan in bronchoalveolar lavage (BAL) specimens in solid organ transplant patients with aspergillosis. The precision and reproducibility in serum or BAL to which galactomannan was added were similar. Sensitivity was 81.8% in patients with aspergillosis, and specificity was 95.8% in lung transplant patients wh...
متن کاملGalactoxylomannan does not exhibit cross-reactivity in the platelia Aspergillus enzyme immunoassay.
Given the recent report of a false-positive result in the Platelia Aspergillus enzyme immunoassay in a patient with cryptococcosis and in yeast extracts and purified galactoxylomannan of Cryptococcus neoformans, we evaluated culture extracts, purified polysaccharides, clinical specimens, and specimens from animals following experimental infection. Our results revealed no cross-reactions.
