El fenómeno más conocido de éstos es el de “swarming”, observado en Proteus spp., en el cual las bacterias sufren una transfiguración importante convirtiéndose en formas filamentosas hiperflageladas.
El género en que mejor se ha estudiado este fenómeno es Proteus, cuyo fenómeno de "swarming" se caracteriza por la formación de círculos concéntricos a partir del punto de inoculación, que le brindan un aspecto de diana a la colonia.
Swarming motility is operationally defined as multicellular, flagella-mediated, surface migration. Swarming also requires an increase in flagellar number, intercellular interactions, and surfactant secretion. Swarming motility has often been genetically bred-out of laboratory strains and is best observed in natural isolates.
28 de may. de 2020 · Proteus mirabilis has unique swarming behavior. Unlike other species that have a single initiation into the swarming phase, P. mirabilis proceeds through iterative swarming and consolidation ( dedifferentiation ) steps to create a bulls-eye pattern of colony 3 (Fig. 2 ).

Proteus mirabilis and Proteus vulgaris are well known to be frequently involved in urinary tract infection pathologies and are also responsible for various systemic and localized infections. Hauser described the characteristic zonal growth of these two species, also called swarming, in 1884 .
