  • Publication number: 20220389435
    Abstract: Methods of controlling bacteria cells are disclosed. These methods comprise upregulating expression of a DVU2956 sigma 54-dependent enhancer-binding protein (EBP) in bacteria cells, resulting in (i) dispersing a biofilm of the cells or reducing biofilm formation by the cells, and/or (ii) reducing hydrogen sulfide formation by the cells. Further disclosed are methods of identifying compounds for controlling bacteria cells as in (i) and/or (ii) above. Polynucleotides and cells are disclosed that can optionally be used to practice compound identification methods.

  • Patent number: 10392671
    Abstract: A method of examining a water supply for microbial contamination involves contacting a water supply with a novel reagent having high specificity for a Legionella microbial species, wherein said reagent does not cross-react, or minimally cross-reacts, with a microbial species other than Legionella. The method further involves detecting, or measuring, a contaminating concentration of a Legionella species in the water supply. Useful reagents comprise at least one nucleotide sequence primer comprising a primer sequence selected from SEQ ID NO: 3-10 or a combination of such primer sequences. The increased specificity of such reagents permits more sensitive detection of microbial contamination.
