Neuraminidases of Bacteroidaceae
Zentralblatt für Bakteriologie, Mikrobiologie und Hygiene. 1. Abt. Originale. A, Medizinische Mikrobiologie, Infektionskrankheiten und Parasitologie, 1981Abstract Neuraminidases can be detected in members of the anaerobic gram-negative non-sporing rods (Bacteroidaceae), especially in the genus Bacteroides. B. fragilis, the most virulent species, has the highest neuraminidase activity, while the other intestinal species exhibit markedly lower activities or the enzyme is completely absent.

Neuraminidase Inhibitors for Influenza [PDF]
he impact of influenza infection is felt globally each year when the disease develops in approximately 20 percent of the world’s population. In the United States, influenza infections occur in epidemics each winter, generally between late December and early March. Recent events, including human cases of avian influenza, have heightened awareness of the

Brain Neuraminidases and Gangliosides
1976A number of data of kinetics nature indicate that brain neuraminidases (the cytosol and the membrane bound enzyme) recognize the physical state of gangliosidic substrate, with immediate modification of the activity. The interactions between the enzyme(s) and the different physical forms of the substrate are still to be studied at the molecular level ...

Influenza vaccine strain selection is informed by international efforts to track antigenic change, focusing on the viral hemagglutinin protein. Recent research advocates monitoring neuraminidase for immune escape mutations that could reduce vaccine efficacy.

The neuraminidase of measles virus
Biochemical and Biophysical Research Communications, 1969The agent of measles (rubeola) has been assumed to be a paramyxovirus on the basis of its electron microscopic appearance, its size, its sensitivity to ether and detergents, and the presence of hemagglutinin in the viral envelope. Thus far, however, the one attribute common to myxoviruses, namely neuraminidase, has not been described for measles virus.

On the intracellular uptake of neuraminidase
Experimental Cell Research, 1966Abstract The intracellular uptake of neuraminidase by three different cell types was studied by two independent methods: (1) measurement of the electrophoretic mobility of nuclei isolated from cells with or without previous neuraminidase treatment and (2) direct observation by fluorescence microscopy of the uptake of fluorescein iso-thiocyanate ...

Isoelectric focusing of neuraminidase
Experientia, 1970Die isoelektrischen Punkte der Neuraminidasen vonVibrio cholerae (pH 4.80) undClostridium perfringens (pH 4.95) wurden mittels isoelektrischer Fokusierung bestimmt. Neuraminidasen zwei verschiedener Influenzaviren (A2/Aichi/68 und B/Mass/66) wurden entsprechend analysiert.

The neuraminidase of influenza virus
Proteins: Structure, Function, and Bioinformatics, 1989AbstractIt is the enzyme neuraminidase, projecting form the surface of influenza virus particles, which allows the virus to leave infected cells and spread in the body. Antibodies which inhibit the enzyme limit the infection, but antigenic variation of the neuraminidase renders it ineffective in a vaccine.

Micro Neuraminidase-Inhibition Assay for Classification of Influenza A Virus Neuraminidases [PDF]
A neuraminidase-inhibition (NI) assay performed in microtiter plates is described. This micro-NI assay is a modification of the NI assay recommended by the World Health Organization. It reduces the quantity of reagents required and permits antigenic classification of many isolates simultaneously.

The neuraminidase-inhibition (NI) assay is a laboratory procedure for the identification of the neuraminidase (NA) glycoprotein subtype in influenza viruses or the NA subtype specificity of antibodies to influenza virus. A serological procedure for subtyping the NA glycoprotein is critical for the identification and classification of avian influenza ...
