[Utilization of the swarming phenomenon for the purpose of isolating pure cultures of salmonellae from feces. II].

A comparative study of the efficacy of two methods of isolation of salmonella from feces was conducted; it was shown that the method based on the capacity of these bacteria to swarming on special elective media was more sensitive than the conventional one. The swarming method proved to be less time consuming and less expensive, because two stages of conventional examination--i.e. enrichment of material and isolation of salmonellae--coincided in time and were carried out on the same media.
