Retrospective Theses and Dissertations

Mycoplasmas are deficient in numerous biosynthetic pathways. Consequently, growth is dependent upon the acquisition of structural and macromolecular precursors from the environment. These precursors include phospholipids, fatty acids and nucleotide bases. DNases and RNases are postulated to be involved in the acquisition of nucleotides. The goals of this study were to determine if nuclease activities are universally associated with mycoplasmas, characterize the nucleases by subcellular distribution and apparent molecular weight, and to identify and analyze the nuclease gene(s) in Mycoplasma pulmonis;Nuclease activity was present in all mycoplasma species tested. The level of activity did not correlate with virulence ...
