Abstract

The aim of the research was to study the species composition of microscopic fungi with toxigenic, pathogenic and allergenic effects in feeds for cage keeping marten.
The 120 samples of feed for martens from fur farms of the Russian Federation were selected. A microbiological study with pure culture of microscopic fungi isolation was performed to establish the species affiliation. Determination of the total toxicity of feed was carried out on white mice and rabbits. The allergy test was performed by applying a fungal allergen to the rabbits’ skin. To determine the pathogenicity of the isolated fungi, a bioassay was conducted on white mice.
It was found that the species composition of microscopic fungi in the feeds for cage keeping marten is represented by eight species: Fusarium sporotrichioides, Aspergillus fumigatus, Aspergillus flavus, Aspergillus niger, Penicillium sp., Mucor racemosus, Rhizopus nigricans, Candida albicans. Pathogenic fungi account for 51 % of the total number of species found. Determin ation of the total toxicity of feed showed that 85,7 % of the studied feed mixture samples and 51,4 % of barley samples have toxicity, due to the presence of Fusarium, Aspergillus, Mucor genus fungi.
