VGXI announces the expansion of its state-of-the-art cGMP manufacturing facility, located in The Woodlands, TX. The Woodlands, TX (PRWEB) December 15, 2014
Staph infections that become resistant to multiple antibiotics don't happen because the bacteria themselves adapt to the drugs, but because of a kind of genetic parasite they carry called a plasmid that helps its host survive the antibiotics.
Studying self-replicating genetic units, called plasmids, found in one of the world's widest-ranging pathogenic soil bacteria -- the crown-gall-disease-causing microorganism Agrobacterium tumefaciens -- Indiana University biologists are showing how freeloading, mutant derivatives of these plasmids benefit while the virulent, disease-causing plasmids do the heavy-lifting of initiating infection in plant hosts.
Scientists involved in DNA vaccine research are currently focused on two major issues: the creation of effective delivery systems and the development of more efficient biomanufacturing strategies, reports Genetic Engineering & Biotechnology News (GEN).
The number of multiresistant strains of bacteria in hospitals is increasing.
Under the microscope, the bacteria start dividing normally, two cells become four and then eight and so on.
Plasmids, which are DNA molecules capable of independent replication in cells, have played an important role in gene technology.
Biodesign Institute at Arizona State University associate research scientist Melha Mellata, a member of professor Roy Curtiss' team, is leading a USDA funded project to develop a vaccine against a leading poultry disease called avian pathogenic E. coli (APEC).
Promega Corporation announces a new plasmid isolation system that simplifies and speeds the preparation of plasmid DNA. The Promega PureYield(TM) Plasmid Miniprep System allows researchers to purify plasmid DNA in less than 10 minutes from 600microl to 3 ml of culture with fewer steps.
