Abstract:
:Swarming Proteus spp. were detected with the use of proteometry (a most-probable-number technique) in the fecal material of selected animal species and in raw sewage from a local sewage treatment plant. Proteus spp. were not detected in any of several soil and freshwater samples examined. Since rat feces harbored high numbers of Proteus mirabilis compared with other habitats examined, we chose to examine it for the possibility of supporting swarming. Immunofluorescent studies with a strain-specific conjugate revealed the morphogenesis of short forms into elongated swarm cells upon the surface of sterilized rat feces that had been inoculated with short forms of P. mirabilis. the same phenomenon was not observed consistently when nonsterile rat feces were inoculated and examined with immunofluorescence.
