[Chemotaxis of Yersinia pseudotuberculosis as a mechanism in its search for target tissues of the host organism].
Y. pseudotuberculosis cells grown at biologically low temperature have been shown capable of chemotaxis with respect to carbohydrates and amino acids. During cultivation at 36-37 degrees C Y. pseudotuberculosis cells retain this property for 10-15 hours and then lose it. The mechanism of chemotaxis makes it possible for Y. pseudotuberculosis to "find" human and animal tissues and can facilitate the realization of the pathogenicity potential of these bacteria. When administered orally to mice motile bacteria, i. e. those grown at 6-8 degrees C, have been more virulent for the animals than nonmotile ones cultivated at 36-37 degrees C.
