conclusions while bdg assay seems to be a sensitive and specific adjunctive tool to diagnose and monitor the experimental systemic candidiasis, it seems that measuring the positive cutoff value in different laboratory conditions is necessary for favorable establishment of these tests. results all the infected rats were positive with bdg tests. an increasing level of bdg was observed during earl...

A method is described for the automated quantitation of the anti-D content of sera. This procedure is far more reproducible than current manual techniques. The use of the International Standard anti-D typing serum in the calibration of a working standard enables results to be expressed in mug/ml of antibody protein.

Normal and immune sera from various animal species were fractionated on columns of Sepharose covalently coupled with the glycoprotein fetuin. Elution of the material bound to fetuin yielded low but reproducible amounts of protein, ranging from 0.02 to 0.2% of the protein mass of the input sera. This material has been identified by immunoelectrophoresis in agar and by zone electrophoresis on cel...

The 51 serotypes of human adenoviruses (HAdVs) of the genus Mastadenovirus are classified into the six species HAdV-A to HAdV-F. For the detection of genus- and species-specific antibodies in human sera an immunoblot assay was developed. The recombinant long fiber of HAdV-41[F] (Ad41Fi) and the native hexon of HAdV-5[C] were used as genus-specific antigens. The recombinant capsid protein IX (pI...

Sera from rams infected with and excreting Brucella ovis in the semen (shedders), as well as from animals which had recovered from previous experimental challenge with B. ovis, were analyzed for their serological reactivities against cytosolic antigens of the bacterium. Membrane vesicles, including outer and inner membrane components, were precluded from the analyses by subjecting French-presse...

A method is described for the simultaneous quantitation of D-arabinitol and D-mannose in serum by gas-liquid chromatography as an aid for the diagnosis of disseminated candidiasis. Both variables were observed as per-O-acetylated aldononitrile derivatives in each chromatographic run of sera from immunosuppressed rabbits experimentally infected with Candida albicans 3181A.

IgA deposition in the glomerular mesangial matrix is a prerequisite for the diagnosis of IgA nephropathy, and circulating IgA-containing complex has been implicated in this process. Since fibronectin is known to be involved in the assembly of extracellular matrix, this study was conducted to investigate whether fibronectin and its fragments are present in sera of patients and are capable of bin...

Abstract Eritrea is an East African multiethnic country with intermediate endemicity for hepatitis B. Our aim was to establish the most prevalent genotypes of B virus (HBV) among patients liver disease. A total 293 Eritrean disease who were surface antigen (HBsAg) positive enrolled. All sera tested transaminases, HBV DNA viral load, and seromarkers including HBsAg, anti-HBcAb (total), HBeAg, an...
