The microbiocenosis of the large intestine in animals with constant radiation exposure in the area of the Chernobyl Atomic Electric Power Station

State of microbiocenosis of large intestine in rats and furo subjected to constant combined irradiation has been studied in full-scale experiments in the emergency rooms of the Chernobyl NPP and in the nearest zone of its effect. The higher diversity of microflora (as compared to initial one), sharp increase of the amount of Candida genus fungi, a decrease of the number of bifidobacteria and increase of the amount of conditionally pathogenic flora were observed in rats with the dose of external irradiation of 1.43 Gr absorbed for 14 days. The expressed associative character of disbioses is distinctly traced. In furo affected by the radion exceeding the background level feeding with products contaminated by radionuclides leads to changes whose individual character corresponds to the picture of disbiosis under radiation injury.
