Cystovirus: Cystovirus is a genus of viruses, in the family Cystoviridae. Pseudomonas bacteria serve as natural hosts.Hepatitis B immune globulinExbivirumabStreptomyces kanamyceticus: Streptomyces kanamyceticus is a bacterial species in the genus Streptomyces. It is the species from which the antibiotic kanamycin is isolated.Widal test: The Widal test, developed in 1896 and named after Georges-Fernand Widal, who introduced it, is a presumptive serological test for enteric fever or undulant fever whereby bacteria causing typhoid fever are mixed with a serum containing specific antibodies obtained from an infected individual. In cases of Salmonella infection, it is a demonstration of the presence of O-soma false-positive result.Hepatitis B virus precore mutant: A precore mutant is a variety of hepatitis B virus that does not produce hepatitis B virus e antigen (HBeAg). These mutants are important because infections caused by these viruses are difficult to treat, and can cause infections of prolonged duration and with a higher risk of liver cirrhosis.Pedigree chart: A pedigree chart is a diagram that shows the occurrence and appearance or phenotypes of a particular gene or organism and its ancestors from one generation to the next,pedigree chart Genealogy Glossary - About.com, a part of The New York Times Company.Silent mutation: Silent mutations are mutations in DNA that do not significantly alter the phenotype of the organism in which they occur. Silent mutations can occur in non-coding regions (outside of genes or within introns), or they may occur within exons.Charged Aerosol Release Experiment: The Charged Aerosol Release Experiment also known as CARE, is a project run by NASA which will use a rocket to release dust in the upper atmosphere to form a dusty plasma in space. NASA plans to trigger cloud formation around the rocket's exhaust particles.Thermal cyclerSpoT: SpoT is a bacterial protein that hydrolizes alarmones, (p)ppGpp, in the bacterial stringent response. Its hydrolase activity is Mn2+-dependent with a conserved His-Asp (HD) motif.SaPI: SaPIs (Staphylococcus aureus or superantigen pathogenicity islands) are a family of mobile genetic elements resident in the genome of some strains of Staphylococcus aureus. Much like bacteriophages, SaPIs can be transferred to uninfected cells and integrate into the host chromosome.Coles PhillipsMichael A. EpsteinSymmetry element: A symmetry element is a point of reference about which symmetry operations can take place. In particular, symmetry elements can be centers of inversion, axes of rotation and mirror planes.BacitracinTemporal analysis of products: Temporal Analysis of Products (TAP), (TAP-2), (TAP-3) is an experimental technique for studying
