[Establishing the types of Dienes compatibility in clinical Proteus mirabilis strains].

The aim of the study was to use the Dienes phenomenon for the differentiation of Proteus mirabilis strains isolated from urine by the method of making possible their typing. The subject of the study were 351 strains of Proteus mirabilis obtained from the laboratory of the Institute of Pediatrics, Medical Academy in Lódź. For establishing of the compatibility type 18 indicator strains were taken, each of them had action antagonistic towards all other ones. The results were read according to the presence or absence of the demarcation line between indicator strains and the studied strain. Out of 351 strains in 190 (54%) the reactions were compatible with one or more indicator strains. They were classified into 30 Dienes compatibility types. In the view of the simplicity and easy performance the method can be used in every microbiological laboratory.
