  Abstract:  The efficiency of seven disinfectants (Terralin, Domestos, Microzid AF, Omnicide, P3-Topax66, Quick javel, Cidex) was tested against Staphylococcus aureus ATCC 25923, Escherichia coli ATCC 25922, Pseudomonas aeruginosa ATCC 27853, Candida albicans ATCC 10231, Bacillus subtilis ATCC 6633, Aspergillus niger ATCC 16404 with surface tests. Surface test were used in order to evaluate the efficiency of disinfectants during the everyday sanitizing practice in the special industrial and hospital surfaces. Test organisms represented pathogen-, spore forming bacteria, yeasts and moulds. Surface test was started with minimal concentration of agents and was not increased above the maximal concentrations which were offered by manufacturers in order not to corrode surfaces or risk the safety of use. Test organisms were inoculated on test areas and after drying inoculated surfaces were treated with disinfectants. Seven disinfectants were tested and four were effective against every test organisms (Omnicide: 0.5 %, P3-Topax66: 5%, Cidex: 100 %, Terralin 0.5 %). Three disinfectants were ineffective against Aspergillus niger (Terralin: 0.2 %, Domestos: 2 %, Topax 0.2) and 1 against Bacillus subrilis and Candida albicans (Microzid AF: 100%).
