The second manufacturer is the Enterprise for the Production of Bacterial and Viral Diagnostics of the Institute of the Russian Academy of Medical Sciences of the Russian Academy of Medical Sciences, also located in Russia. The nutrient medium is produced in the form of a sterile liquid solution in 450 ml bottles, intended for the detection of microbes in samples of biological fluids and tissues of humans or animals.
