Antigenic Analysis of Influenza B Virus Isolated from the Epidemic in 1973 [PDF]

, 1985
1985-01Antigenic relationships between an isolate (B/Aichi/1/73) from the epidemic of influenza B in 1973 and earlier strains of the same type were studied by hemagglutination-inhibition and neuraminidase-inhibition tests. The results showed that B/Aichi/

Effects of the HN Antigenic Difference between the Vaccine Strain and the Challenge Strain of Newcastle Disease Virus on Virus Shedding and Transmission

Viruses, 2017
Newcastle disease (ND) leading to heavy economic losses to the poultry industry worldwide is caused by Newcastle disease virus (NDV). Even though intensive vaccination programs have been implemented in many countries, virulent NDV can still be frequently

A neuraminidase activity-based microneutralization assay for evaluating antibody responses to influenza H5 and H7 vaccines. [PDF]

PLoS ONE, 2018
Outbreaks of the highly pathogenic avian influenza H5N1 and H7N9 viruses have spurred an unprecedented research effort to develop antivirals and vaccines against influenza. Standardized methods for vaccine evaluation are critical for facilitating vaccine

Standardized Viral Hemagglutination and Hemagglutination-Inhibition Tests. II. Description and Statistical Evaluation [PDF]

Applied Microbiology, 1969
Standardized hemagglutination and hemagglutination-inhibition procedures are described and statistically evaluated for all animal viruses where applicable, except for rubella and the arbovirus group. The standardized tests employ a constant phosphate-buffered saline diluent and constant volumes of serum, antigen, and standardized erythrocyte suspension.

Isolation and Identification of Egg Drop Syndrome Virus with Hemagglutination and Hemagglutination Tests

, 2015
Egg drop syndrome (EDS) is a disease that attacks layer hens in the production phase causing failure of peak eggs production, decreased in eggs production, and presence of eggs without shell. This study was conducted to isolate and identify the EDS virus

SARS‐CoV‐2 enhances lysosomal exocytosis and deacidifies lysosomes to facilitate viral release

mLife, EarlyView.
Abstract The mechanism of SARS‐CoV‐2 egress predominantly governs the quantity and quality of progeny viruses, thereby significantly contributing to viral pathogenicity. However, the key factors influencing viral egress remain largely unclear. In this study, using transcription‐ and replication‐competent SARS‐CoV‐2 virus‐like‐particle (SARS‐CoV‐2 trVLP)

Monoclonal antibodies to hemagglutinin of influenza A/H7N3 virus (Orthomyxoviridae: Alphainfluenzavirus: Influenza A virus)

Вопросы вирусологии, 2021
Introduction. Variants of influenza virus A/H7 have the same high pandemic potential as A/H5. However, the information about the antigenic structure of H7 hemagglutinin (НА) is considerably inferior in quantitative terms to similar data for H5 НА.

Hemoagglutination and hemagglutination inhibition tests with enterovirus type 70 [PDF]

Journal of Clinical Microbiology, 1978
Human type "O," guinea pig, and chicken erythrocytes were agglutinated by enterovirus type 70 at 4 degrees C or room temperature. A hemagglutination inhibition test, using human "O" erythrocytes, is described for the serological diagnosis of acute hemorrhagic conjunctivitis caused by enterovirus type 70.
