In Brazil, the percentage of infected dogs living in areas where canine visceral leishmaniasis (CVL) is endemic ranges from 10 to 62%; however, the prevalence of infection in dogs is probably higher than figures reported from serological studies. In addition, problems with the occurrence of false-positive or false-negative results in the serodiagnosis of CVL have been reported. The present work...
Detection of anti-Burkholderia pseudomallei antibodies in sera from melioidosis patients still represents a keystone in the confirmation of the clinical diagnosis, especially in non-endemic areas. An in-house assay was compared to lateral flow assays for the rapid detection of melioidosis-specific IgG or IgM. Employing 50 positive sera from patients and 200 negative sera from blood donors, sens...
This study was designed to compare the sensitivity and specificity of enzyme linked immunosorbent assay (ELISA) for the serodiagnosis of ocular toxocariasis using Toxocara canis embryonated egg antigen (TEE) and toxocara excretory-secretory or exoantigen (TEX) produced in vitro. TEE and TEX ELISA were comparably sensitive, but TEX ELISA was better able to discriminate between serum samples from...
The dot immunobinding assay, a rapid, visually read test, was adapted for serodiagnosis and follow-up of paracoccidioidomycosis (PCM). Purified gp43 antigen was tested before and after sodium metaperiodate treatment. To evaluate the assay, it was tested with sera from PCM, histoplasmosis, Jorge Lobo's disease, aspergillosis, candidiasis, and cryptococcosis patients and healthy subjects. Native ...

A nitrocellulose membrane strip dotted with a specific 50 kDa outer membrane protein of Salmonella typhi was applied for the serodiagnosis of typhoid fever. Using horseradish peroxidase conjugated IgM and IgG antibodies with 4-chloronaphthol as substrate, antibodies in typhoid patients were clearly visualised as bluish purple dots while sera from patients with non-typhoid fevers gave negative r...
