Dengue virus cross-reactive hemagglutination inhibition antibody responses in patients with primary dengue virus infection.
Acute and convalescent plasma samples were obtained from 101 confirmed primary dengue cases: 48 cases infected with dengue virus type 1, 10 cases with type 2, 42 cases with type 3 and one case with type 4. The hemagglutination inhibition (HI) titers of individual samples were at levels similar to each of the 4 dengue viruses at both the acute and convalescent stages, irrespective of the dengue ...
متن کاملHemagglutination by rabies virus.
Goose erythrocytes were agglutinated by five strains of rabies virus grown in monolayer cell cultures at pH 6.4 and at 0 to 4 C. Hemagglutination was not affected by the cell type in which the virus was grown. Prerequisites for occurrence of hemagglutination are absence of hemagglutination inhibitors (such as those contained in bovine serum) and a relatively high virus concentration (> 10(6) pl...
متن کاملStudies on hemagglutination activity of caprine herpesvirus-1
The aim of this study was to investigate the hemagglutination properties of caprine herpesvirus-1(CpHV-1) and their application for CpHV-1 antigen detection and evaluation of the dynamics of postinfectious/vaccine antibody production. CpHV-1 hemagglutination activity was proved only with mouseerythrocytes, PBS and saline solutions at 4°C and 22°C. In vaccinated animals, goats and bucks withresp...
متن کاملAnalysis of the diluents used for rubella virus hemagglutination and hemagglutination-inhibition tests.
A new diluent (ADGP) for the rubella virus hemagglutination (HA) and hemagglutination-inhibition (HI) tests is described. It was found that the HA and HI titers and the erythrocyte agglutination pattern were improved in ADGP compared to previously described diluents. The influence of the components of ADGP and of various test conditions on optimal HA and HI results were examined.
متن کاملStandardized viral hemagglutination and hemagglutination-inhibition tests. I. Standardization of erythrocyte suspensions.
A spectrophotometric procedure for standardizing red blood cell suspensions for use in viral hemagglutination tests is described. The procedure is based on highly reproducible cyanmethemoglobin absorbance readings at 540 nm on any suitable spectrophotometer. Target values for milligrams of cyanmethemoglobin per 100 ml are given for the red cell suspensions of all mammalian and avian species emp...
