Ethidium bromide resistance, a new marker on the staphylococcal penicillinase plasmid.
A strain of Staphylococcus aureus resistant to ethidium bromide is described. The genetic determinants for the resistance are present on the same plasmid as the penicillinase genes.
متن کاملSelf-induced nystatin resistance in Dictyostelium discoideum.
The cellular slime mold Dictyostelium discoideum is normally susceptible to the action of the polyene antibiotic nystatin. We describe conditions under which transient nystatin resistance can be induced in the absence of detectable changes in sterol composition. These results suggest that nystatin plays a positive role in promoting resistance to itself.
متن کاملMechanism of Ethidium Bromide Fluorescence Enhancement on
The mechanism of the enhancement of the fluorescence of ethidium bromide on binding to double helical RNA and DNA has been investigated. From an examination of the effect of different solvents on the fluorescence lifetime, quenching of fluorescence by proton acceptors, and the substantial lengthening of lifetime observed upon deuteration of the amino protons, regardless of the medium, we conclu...
متن کاملDictyostelium discoideum
Dictyostelium discoideum is a cellular slime mold [4] that serves as an important model organism [5] in a variety of fields. Cellular slime molds have an unusual life cycle. They exist as separate amoebae, but after consuming all the bacteria in their area they proceed to stream together to form a multicellular organism. These features make them a valuable tool for studying developmental proces...

cernible. The peroxidase technique also permits the specimen to be examined by electron microscopy. Perhaps a few too many chapters are devoted to individual applications of the technique, but it is an exciting development in diagnostic virology. Viral genomes can be present in cells without full expression leading to the production of viral antigens or virions which can be detected by immunolo...
