[Evaluation of the results of animal studies with a scheme of serologic reactions according to a table of standards]. / Otsenka dannykh issledovaniia zhivotnykh v sisteme serologicheskikh reaktsii po étalonnoi setke.

The authors suggest a method of processing of the data of examination of the animals in the system of serological reactions for the purpose of diagnosis of epizootic situations in the natural plague foci. Positive results are recorded in a table in the form of a grid whose cells correspond to all possible variants of the two reaction titres. The table is divided into 6 sections into which the results differing by the correlation and the absolute reaction titres (the standard grid) are placed. The frequency of reactions is determined by the grid sections in the regions in which the character of the epizootic development in nature was studied by bacteriological examination of the animals. The diagnostic scale is drawn by the results of such standard observations. The trial of the suggested method was carried out in the regions of plague epizootics among the Rhombomys optimus Licht. in the Lowland Kara-Kum; it was possible to differentiate the signs of epizootic situations there in greater detail than by the methods suggested earlier.
