Abstract
It was established that the exometabolites of Aranicola spp., isolated from beef, promoted the reversion of nonculturable forms of Listeria monocytogenes, isolated from the same product, into the proliferative state, influencing the expression of their biological properties, which was expressed by a change in the morphology and enzymatic properties of the colony, and also by an increase the hemolytic activity and a decrease in adhesiveness. It was noted that all changes in the biological properties of L. monocytogenes were phenotypic. Passage in trypticase-soy broth with further seeding of Listeria on yeast agar after the third passage led to a gradual change in the biological properties, until their complete recovery after the fifth passage on the sixth day of the study.
