A resident microorganism (strain Kho-17) was isolated from secretions of the specific glandular structures at the angles of mouth of Djungarian hamster (Phodopus campbelli). According to cultural, morphological, and physiological properties as well as to the phylogenetic analysis basing on the sequences of 16S rRNA gene and analysis of the cell wall the strain was assigned to the species Microbacterium oxydans. The bacterium isolated displayed probiotic properties when administered orally as a suspension of live cells for 20 days to Syrian hamster (Mesocricetus auratus), which manifested themselves in increased body weight and weights of several organs and stimulation of both cell-mediated and humoral immunities.
