Paracoccidioides brasiliensis antigen batches from the same isolate show immunological and biochemical differences
We investigated the occurrence of antigenic and biochemical variability among Paracoccidioides brasiliensis antigen batches prepared according to the same protocol. Initially (experiment 1), we analyzed two antigen lots ...
Role of TLR-2 and fungal surface antigens on innate immune response against Sporothrix schenckii
Sporotrichosis is an infection caused by the dimorphic fungus Sporothrix schenckii. Toll-like receptors (TLRs) play an important role in immunity, since they bind to pathogen surface antigens and initiate the immune response. ...
The use of a mixture of somatic and culture filtrate antigens in the evaluation of the immune response to Paracoccidioides brasiliensis
(Blackwell Science, 1991-10-11)
Three Paracoccidioides brasiliensis antigens, namely a culture filtrate preparation, a somatic antigen and a mixture of equal parts of the two, were tested by two serological techniques against sera from patients with ...
Specific components found in circulating immune complexes (CIC) in paracoccidioidomycosis
Circulating immune complexes (CIC) from 15 paracoccidioidomycosis (PCM) patient sera and from 20 healthy control sera were analysed. After CIC precipitation, solubilization and acid treatment, only a little reactivity to ...
Indirect fluorescent test for detection of anti-Paracoccidioides brasiliensis antibodies using coated bentonite particles as antigen
An indirect fluorescent test was developed for detecting antibodies to Paracoccidioides brasiliensis using bentonite particles as antigen (Bent-IF). The bentonite particles were coated with P. brasiliensis polysaccharide ...
