To simulate contamination there were used categorized strains of mold species most often occurring in holding in cold lactic products (Aspergillus niger, Mucor racemosus, Penicillium expansum, Fusarium oxysporum, Geotrichum candidum). 10%-fatness cream was contaminated with a spore suspension of each fungus. The experiment was performed on male arts for 28 days. The animals of groups 1 and 2 received intragastrically through a probe contaminated cream, the animals of group 3 received uncontaminated cream. Each group has 10 animals. The dosage of cream was 1 g/kg of body weight. The animals demonstrated misbalance of enteric microflora: in large intestine there was declined the content of bifid bacteria, in the wall of small intestine bifid and enteric bacteria penetrated in amounts untypical for this animal species, the content of enteric bacteria and enterococci decreased, their species composition unfavorably changed. The antagonistic activity of aerobic microflora component decreased, and the occurrence of conventionally pathogenic species of enteric bacteria increased. At the same time there was observed the growth of specific activity of lactic bacteria being antagonists of molds. It is concluded that even under relatively low contamination level spores of non-toxicogenous molds cam be dangerous for consumers health.
