Prevention of assay interference in infectious-disease serology tests done on the liaison platform.

Acute parvovirus B19 infection frequently causes false-positive results in Epstein-Barr virus- and herpes simplex virus-specific immunoglobulin M determinations done on the Liaison platform.

During an outbreak of parvovirus B19 we collected serum samples from 68 nonpregnant patients in the region of Antwerp (Belgium). Fifty-seven (84%) of the parvovirus B19 immunoglobulin M (IgM)-positive sera had a positive result for Epstein-Barr virus (EBV) IgM by Liaison testing, 61 (90%) had a positive result for herpes simplex virus (HSV) IgM, 20 (29%) samples were positive for cytomegaloviru...

Dengue Fever Serology in Febrile Patients in Southeast Iran

High prevalence of dengue fever in Pakistan bordering southeast Iran emphasizes the need for paying more attention to monitoring of the disease in this region. The aim of this study was to study the dengue...

Isolation, Characterization and Standardization of New Infectious Bursal Disease Virus for Development of a Live Vaccine

Background and Aims: Infectious bursal disease (IBD) is an acute contagious viral disease of birds worldwide. The causative virus induces a persistent immune suppression following destroy B lymphocytes precursors in bursal lymphoid follicles. Vaccination is the main strategy for prevention of the disease in commercial poultry industry. Materials and Methods: To produce a live vaccine against th...

Schistosomiasis serology is valuable and reliable.

TO THE EDITOR—We read the photo quiz authored by Bagdure and Khasawneh with interest [1]. The authors described a case of schistosomiasis colitis caused by Schistosoma mansoni, which was diagnosed after review of hematoxylin-eosin– stained colonic biopsy sections. This case emphasizes the challenges associated with obtaining a laboratory diagnosis of schistosomiasis based on examination of ova ...
