  Abstract:  The efficiency of a disinfectant depends on its intrinsic biocide activity, the used concentration, time of contact, the nature of treated surfaces, hardness of water used to dilute the disinfectant, the organic substances present on the surfaces in question, the type and number of microorganisms present. Our goal was to study the fungicide effect of disinfectants in different concentrations, used for disinfection of surfaces in food industry and sanitary institutes, as well as to classify them according to their efficiency on fungi. To determine the fungicide effect of chemical disinfectants, we have used the method of surface test. We have also used a positive sample for comparison. We have determined the average survival, we computed the logarithmical reduction and the data have been processed with the Kruskal-Wallis statistic test. We have tested the effect of 8 disinfectants (P3-Topax 66, Omnicide, Terralin, Microzid AF, Javel Chloride, DJP-anios, DVA-anios, Suprasept) on the development of 5 types of fungi (Candida albicans, Aspergillus niger, Penicillium sp., Mucor sp., Alternaria sp. ) on different surfaces (faience, glass, vinyl plastic, wood, stainless steel). We have found that their efficiency depends on the type of fungi and the tested surface. The efficiency of disinfection is decisively influenced by the chosen disinfectant and its concentration.
