RESEARCH OF ANIMAL MICROFLORA AT THE IMPERIAL KAZAN UNIVERSITY (BASED ON THE MATERIALS OF N.I. ORLOV)M.V. TrushinAbstract Qualitative and quantitative determination of the intestinal microflora is currently one of the tools for studying the physiological state of both human and animal organisms. Historically, the first observations in this area belong to the turn of the XIX-XX centuries. This article highlights the issues of determining the presence of paratyphoid microbes in the feces of dogs, made at the beginning of the XX century by the Kazan bacteriologist N.I. Orlov. Data on its methodological approaches to culture and identification of the studied group of bacteria are presented, which is of interest from the point of view of the history of development of microbiological and immunological methods. |
