A gene encoding an antigenic mannoprotein of Penicillium marneffei, MPLP6, was isolated by an antibody screening approach and characterized. The polypeptide chain containing deduced 220 amino acids has a predicted molecular mass of 24 kDa. It has high similarity to Mp1p, the first mannoprotein antigen isolated from P. marneffei. The polypeptide sequence presents the property of cell wall mannop...
Tuberculosis in cattle remains a major zoonotic and economic problem in many countries. The standard diagnostic assay for bovine tuberculosis, the intradermal tuberculin test, has low accuracy. Therefore, alternative immunodiagnostic methods, such as serological assays, are needed for detection of infected animals. Development of an accurate serodiagnostic test requires a detailed understanding...
In this study, we examined the diagnostic accuracy of the InBios Scrub Typhus Detect IgM enzyme-linked immunosorbent assay (ELISA) and determined the optimal diagnostic optical density (OD) cutoffs for screening and diagnostic applications based on prospectively collected, characterized samples from undifferentiated febrile illness patients in northern Thailand. Direct comparisons with the sero...
The aim of this descriptive study was to investigate the relationships between serum antibody responses to different mycobacteria in leprosy patients and contacts. The results of ELISAs for serum antibody against whole mycobacteria (Mycobacterium leprae, M. tuberculosis, and M. scrofulaceum) were compared with the results of an M. leprae-specific ELISA for antibody against an epitope of PGL l ....
The Western blot for cysticercosis, which uses lentil lectin purified glycoprotein (LLGP) antigens extracted from the metacestode of Taenia solium, has been the "gold standard" serodiagnostic assay since it was first described in 1989. We report that the diagnostic antigens at 14, 18, and 21 kDa, as well as some larger disulfide-bonded antigens, are actually all members of a very closely relate...
Leptospirosis is one of the zoonotic diseases in animals and humans throughout the world. LipL21 is one of the important surface-exposed lipoproteins in leptospires and the most effective cross protective immunogenic antigen. It is widely considered as a diagnostic marker for leptospirosis. In this study, we evaluated the serodiagnostic potential of LipL21 protein of Leptospira interrogans sero...
Borrelia crocidurae-associated relapsing fever is endemic to West Africa and is considered benign. We report 4 patients with B. crocidurae-associated neurologic symptoms; 2 of their cases had been misdiagnosed. Frequency and severity of this disease could be underestimated; molecular methods and serodiagnostic tests for Lyme disease might be helpful in its detection.
Diagnostic Methods for and Clinical Pictures of Polyomavirus Primary Infections in Children, Finland
We used comprehensive serodiagnostic methods (IgM, IgG, and IgG avidity) and PCR to study Merkel cell polyomavirus and trichodysplasia spinulosa-associated polyomavirus infections in children observed from infancy to adolescence. Comparing seroconversion intervals with previous and subsequent intervals, we found that primary infections with these 2 viruses were asymptomatic in childhood.
Sera from patients with leprosy agglutinated killed H37Rv Mycobacterium tuberculosis to varying degrees. Higher titres were found in association with active disease but there was no difference between patients at the lepromatous or at the tuberculoid ends of the clinical scale. A sharp rise in titre occurred during the active phase of an episode of erythema nodosum leprosum.
To evaluate commercially available diagnostic kits for human immunoglobulin G to Toxoplasma gondii, we purchased three enzyme immunoassay (EIA) (Cordia-T, Toxo Bio-EnzaBead, and Toxoelisa), two indirect hemagglutination (IHA) (TPM-Test and ToxHAtest), one fluoroimmunoassay (Toxoplasma-G FIAX), and one latex agglutination (Eiken Toxotest-MT) kit from U.S. suppliers. A total of 100 serum specimen...
