Enterotoxin B: Serological Assay in Cultures by Passive Hemagglutination [PDF]

Applied Microbiology, 1967
Bis-diazotized benzidine hemagglutination with Formalinized sheep erythrocytes was adapted to the rapid and specific detection of enterotoxin B in staphylococcal culture fluids. There was complete agreement between hemagglutination inhibition (HI) and gel diffusion in detecting 8 enterotoxin B-positive cultures from a total of 68 staphylococcal ...

An Open Receptor-Binding Cavity of Hemagglutinin-Esterase-Fusion Glycoprotein from Newly-Identified Influenza D Virus: Basis for Its Broad Cell Tropism. [PDF]

, 2016
Influenza viruses cause seasonal flu each year and pandemics or epidemic sporadically, posing a major threat to public health. Recently, a new influenza D virus (IDV) was isolated from pigs and cattle. Here, we reveal that the IDV utilizes 9-O-acetylated

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 ...

Generation of virus-specific cytotoxic T cells in vitro I. Induction conditions of primary and secondary Sendai virus-specific cytotoxic T cells [PDF]

, 1979
H-2-restricted cytotoxic T cells specific for Sendai virus were generated in vitro in a primary response from normal mouse lymphocytes cultured in the presence of infective as well as inactivated Sendai virus. Antigen-presenting cells of different origin,

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.

Improvement of the indirect hemagglutination test for the detection of antibodies to Streptococcus pyogenes

Brazilian Journal of Medical and Biological Research, 1998
An indirect hemagglutination test for a seroepidemiological survey of Streptococcus pyogenes infection was standardized. This is an improved modification of the indirect hemagglutination test which utilizes an unstable reagent prepared with fresh blood ...

Forward Genetic Dissection of Biofilm Development by Fusobacterium nucleatum: Novel Functions of Cell Division Proteins FtsX and EnvC. [PDF]

, 2018
Fusobacterium nucleatum is a key member of the human oral biofilm. It is also implicated in preterm birth and colorectal cancer. To facilitate basic studies of fusobacterial virulence, we describe here a versatile transposon mutagenesis procedure and a ...

Cross-protection against European swine influenza viruses in the context of infection immunity against the 2009 pandemic H1N1 virus : studies in the pig model of influenza [PDF]

, 2015
Pigs are natural hosts for the same influenza virus subtypes as humans and are a valuable model for cross-protection studies with influenza. In this study, we have used the pig model to examine the extent of virological protection between a) the 2009 ...
