Microflora of the polar bear (Ursus maritimus) from natural population of the Russian Arctic
The paper presents the results of studying the microflora of the polar bear (Ursus maritimus) organism. Samples from 22 individuals were collected during three comprehensive scientific expeditions arranged in 2014 and 2015 at the request of PJSC Rosneft Oil Company. Based on the results of laborator...
