A method for imparting to an article or product antimicrobial activity includes a step of applying an antimicrobial agent containing an antimicrobial polyaminosilane to the article or product. The antimicrobial polyaminosilane is prepared by subjecting an aminosilane monomer to a hydrolysis and condensation reaction. The antimicrobial polyaminosilane thus prepared is free of halide ions.

The invention relates to a preparation comprising a) 10 to 80% by weight of ,,-trimethyl-1,3,5-triazine-1,3,5-(2H,4H,6H) triethanol (TTT) and b) one or more additives selected from i) ammonia, ii) alkanolamines with primary amino group and alkyl group having at most eight carbon atoms and iii) alkylamines with primary amino group and alkyl group having at most eight carbon atoms, where the weight ratio a):b) is in the range from 100:30 to 100:1. The preparation is present as semi-concentrate and has an advantageously lower viscosity, is moreover storage-stable, in particular storage-stable over a long period.

Agents and formulations and cells including plant extracts are useful in a method for controlling pathogen infestation in human and animal subjects. A method for inhibiting growth or infestation of a pathogen in or on a human or animal subject, includes contacting the pathogen with an effective amount of a combination of a plant defensin or a functional natural or synthetic derivative or variant thereof and either: (i) a proteinase inhibitor; or (ii) a chemical pathogenicidic or pathogenostatic agent; in a combined amount effective to inhibit growth or infestation of the pathogen.
