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

open access: yes, 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 ...

International Laboratory Comparison of Influenza Microneutralization Assays for A(H1N1) pdm09, A(H3N2), and A(H5N1) Influenza Viruses by CONSISE [PDF]

open access: yes, 2015
The microneutralization assay is commonly used to detect antibodies to influenza virus, and multiple protocols are used worldwide. These protocols differ in the incubation time of the assay as well as in the order of specific steps, and even within ...

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

open access: yesApplied 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 ...

Cross-species infectivity of H3N8 influenza virus in an experimental infection in swine [PDF]

open access: yes, 2015
Avian influenza A viruses have gained increasing attention due to their ability to cross the species barrier and cause severe disease in humans and other mammal species as pigs.

Clinical Features That Affect Indirect-Hemagglutination-Assay Responses to Burkholderia pseudomallei

open access: yesClinical and Vaccine Immunology, 2009
Melioidosis, a disease endemic to northern Australia and Southeast Asia, is caused by the soil saprophyte Burkholderia pseudomallei. The indirect hemagglutination assay (IHA) is the most frequently used serological test to help confirm exposure to the ...

Carbohydrate specificity of sea urchin sperm bindin: a cell surface lectin mediating sperm-egg adhesion. [PDF]

open access: yes, 1982
We have examined the carbohydrate specificity of bindin, a sperm protein responsible for the adhesion of sea urchin sperm to eggs, by investigating the interaction of a number of polysaccharides and glycoconjugates with isolated bindin.

Next‐Generation Bio‐Reducible Lipids Enable Enhanced Vaccine Efficacy in Malaria and Primate Models

open access: yesAdvanced Functional Materials, EarlyView.
Structure–activity relationship (SAR) optimization of bio‐reducible ionizable lipids enables the development of highly effective lipid nanoparticle (LNP) mRNA vaccines. Lead LNPs show superior tolerability and antibody responses in rodents and primates, outperforming approved COVID‐19 vaccine lipids.

TRYPSIN-INDUCED HEMAGGLUTINATION ASSAY FOR THE DETECTION OF INFECTIOUS BRONCHITIS VIRUS [PDF]

open access: yesPakistan Veterinary Journal, 2004
A trypsin-induced hemagglutination (THA) assay was standardized to detect infectious bronchitis virus (IBV) in allantoic fluid (AF) of embryonated eggs.

Heterologous prime-boost vaccination with H3N2 influenza viruses of swine favors cross-clade antibody responses and protection [PDF]

open access: yes, 2017
The emergence of multiple novel lineages of H1 and H3 influenza A viruses in swine has confounded control by inactivated vaccines. Because of substantial genetic and geographic heterogeneity among circulating swine influenza viruses, one vaccine strain ...
