[A microflora study of the gastrointestinal tract of mink housed within and outside of the area of the Chernobyl Atomic Electric Power Station].
Quantitative differences in the content of lactic acid bacteria isolated from the content of the stomach, small and large intestine have been established when studying microflora of the gastrointestinal tract of minks kept in the 30-kilometer zone of the Chernobyl NPP (experimental animals) and at the Cherkassy fur farm (control animals). Obligate heterofermentative species of lactic acid bacteria related to Lactobacillus fermentum and L. reuteri prevailed in the stomach of experimental minks. Species composition of lactic acid bacteria isolated from the stomach of the Cherkassy minks is characterized by the availability of both obligate and facultative heterofermentative species of bacteria--L. bavaricus, L. coryniformis, L. reuteri and of obligate homofermentative bacteria--L. salivarius and L. jensenii. In limiting dilutions (10(-9)-10(-10)) of the content of small intestine of the control minks one could find bacteria of L. coryniformis species and representatives of obligate heterofermentative bacteria--L. confusus and L. fermentum that is 1-2 orders higher then in the experimental minks. Both lactic acid bacteria and bifidobacteria (the latter up to 10(+9) cells/g of the content) were isolated from the lower departments of small and large intestine of the Chernobyl and Cherkassy minks. Among the species of lactic acid bacteria isolated from the experimental animals homofermentative species (L. acidophilus, L. sharpeae) and, heterofermentative (L. confusus, L. fermentum) in the control were found.(ABSTRACT TRUNCATED AT 250 WORDS)
