title: [Actinomyces thermovulgaris endospores].
abstract: It has been established for the first time that autolysis observed when Actinomyces thermovulgaris T-54 is cultivated on liquid media of various composition is caused by the formation of submerged spores. These, in contrast to exospores of the majority of the actinomycetes, are endospores according to their structure and the following criteria: thermostability, the presence of dipicolinic acid, the structure of ultrathin cross-sections studied by electron microscopy, the resistance to novobiocin.
