Plaque titration and inhibition tests for bovine parvovirus.

Multiplication of bovine parvovirus in two cell strains.

Bovine parvovirus has been found to infect two cell strains: buffalo lung fibroblasts and embryonic bovine tracheal cells. Infectivity titers were best determined by plaque assays. Immunofluorescence studies revealed intranuclear staining, whereas complement fixation tests confirmed bovine parvovirus antigen production. These cell strains represent economical and convenient cell types which can...

Development of Plaque Techniques for Titration and Neutralization Tests with African Horse-Sickness Virus

One-step immunochromatography assay kit for detecting antibodies to canine parvovirus.

This study was performed to determine the feasibility of using whole serum to detect antibodies to canine parvovirus (CPV) under nonlaboratory conditions and to evaluate the performance characteristics of an immunochromatography assay kit. Precise detection of levels of antibody against CPV in puppies can be used to determine a vaccination schedule, because maternal antibodies frequently result...

Aphidicolin inhibition of the production of replicative-form DNA during bovine parvovirus infection.

Since parvoviruses apparently do not possess a DNA polymerase activity, one or more of the host cell DNA polymerases must be responsible for replicating the single-stranded DNA genome. We have focused on determining which polymerase, alpha, beta, or gamma (pol alpha, pol beta, or pol gamma, respectively), is responsible for the first step in bovine parvoviral DNA replication: conversion of the ...

Derivation of neutralizing monoclonal antibodies against rotavirus.

Monoclonal antibodies were derived against the SA11 simian, NIC bovine, and Wa human rotavirus strains and characterized by enzyme-linked immunosorbent assay, plaque neutralization, and hemagglutination inhibition. Several strain SA11-specific antibodies were found to have neutralizing and hemagglutination-inhibiting capacity.
