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.

Abstract:
A synergistic microbicidal composition having two components. The first component is a nonionic surfactant with structure: R 2 0(CH 2 CH(CH 3 )0) 3 (CH 2 CH 2 0) 5 H, where R 2 is a mixture of C 8 -C 14 linear alkyl groups. The second component is 2-bromo-2- nitropropane-l,3-diol (bronopol), tetrahydro-3,5-dimethyl-2H-l,3,5-thiadiazine-2-thione (dazomet) or a mixture of 4-(2-nitrobutyl) morpholine and 4,4'-(2-ethyl-2-nitrotrimethylene)dimorpholine.
Abstract:
A synergistic microbicidal composition having two components. The first component is a nonionic surfactant with structure: R 1 O(CH 2 CH(CH 3 )O) 5 (CH 2 CH 2 O) 9 H, where R 1 is a C 8 alkyl group. The second component is 2-methyl-4-isothiazolin-3-one. The weight ratio of the nonionic surfactant to 2-methyl-4-isothiazolin-3-one is from 1:0.005 to 1:1.3714. Alternatively, the first component is a nonionic surfactant with structure: R 2 O(CH 2 CH(CH 3 )O) 3 (CH 2 CH 2 O) 7 H, where R 2 is a mixture of C 8 -C 14 linear alkyl groups. The second component is 2-methyl-4-isothiazolin-3-one. In this case, the weight ratio of the nonionic surfactant to 2-methyl-4-isothiazolin-3-one is from 1:0.006 to 1:0.9143.
