Prevalence of antibodies against avian influenza A (H5N1) virus among Cullers and poultry workers in Ho Chi Minh City, 2005. [PDF]

PLoS ONE, 2009
Between 2003 and 2005, highly pathogenic avian influenza A (H5N1) viruses caused large scale outbreaks in poultry in the Ho Chi Minh City area in Vietnam. We studied the prevalence of antibodies against H5N1 in poultry workers and cullers who were active

The Hemagglutination-inhibition Assay for Thrombopoietin [PDF]

Blood, 1973
Abstract A sensitive immunoassay procedure for the detection of the thrombopoietic-stimulating factor (TSF) has been developed. This procedure is similar to the hemagglutination-inhibition (HAI) technique that is available for erythropoietin.

Microtiter Hemagglutination-Inhibition Assay for Staphylococcal Enterotoxin B [PDF]

Applied Microbiology, 1967
The rapid microtiter technique was investigated as a means of facilitating the detection of staphylococcal enterotoxin B. With this technique, many samples were assayed simultaneously, and readable results were obtained in 3 hr. Other advantages of this method, in addition to speed, were the small quantity of reactants used, ease of reading, and ...

Improved Hemagglutination Inhibition Assay for Mammary Tumor Virus Antigen [PDF]

Applied Microbiology, 1973
It is our experience that the use of sheep red blood cells pretreated with formaldehyde and pyruvaldehyde before sensitizing with viral antigen yields results that are comparable to that obtained by using the tannic acid method. The double aldehyde method provides the added advantage of being useful for assaying the viral antigen content in substances ...

Qualification of the Hemagglutination Inhibition Assay in Support of Pandemic Influenza Vaccine Licensure [PDF]

Clinical and Vaccine Immunology, 2009
ABSTRACT Continued outbreaks of highly pathogenic avian influenza over the past decade have spurred global efforts to develop antivirals and vaccines. As part of vaccine development, standard methods are needed for determining serum antibody titers in response to vaccination.

Sensitive detection systems for infectious agents in xenotransplantation*

Xenotransplantation, EarlyView., 2020
Abstract Xenotransplantation of pig cells, tissues, or organs may be associated with transmission of porcine microorganisms, first of all of viruses, to the transplant recipient, potentially inducing a disease (zoonosis). I would like to define detection systems as the complex of sample generation, sample preparation, sample origin, time of sampling ...

A comparison of hemagglutination inhibition and neutralization assays for characterizing immunity to seasonal influenza A [PDF]

Influenza and Other Respiratory Viruses, 2016
BackgroundSerum antibody to influenza can be used to identify past exposure and measure current immune status. The two most common methods for measuring this are the hemagglutination inhibition assay (HI) and the viral neutralization assay (NT), which have not been systematically compared for a large number of influenza viruses.MethodsA total of 151 ...

Influenza Virus Hemagglutinin Stalk-Specific Antibodies in Human Serum are a Surrogate Marker for In Vivo Protection in a Serum Transfer Mouse Challenge Model

mBio, 2017
The immunogenicity of current influenza virus vaccines is assessed by measuring an increase of influenza virus-specific antibodies in a hemagglutination inhibition assay.
