Abstract

Caves are extreme ecosystems whose microbiomes are very sensitive to invasion by extraneous microbial species. The entry of such organisms from one cave into another can occur due to anthropogenic transfer, which makes it possible to bypass natural barriers. The article presents materials on the analysis of microscopic fungi contamination of clothing and equipment after working in caves. It is shown that after visiting the cave Kinderlinskaya and Shulgan-Tash, a significant number of micromycete species settle on clothes and equipment. Twenty-one species of microscopic fungi were found, as well as yeast, light and dark-colored sterile forms. The isolated species correspond to the typical species composition of fungi in a particular cave. Gloves turned out to be the most contaminated. Washing made it possible to significantly reduce the number and species richness of micromycetes on clothes. Thus, following simple rules can significantly reduce the risk of anthropogenic transfer of microorganisms between caves.
