Comparative analysis of extreme acid survival in Salmonella typhimurium, Shigella flexneri, and Escherichia coli.
Several members of the family Enterobacteriaceae were examined for differences in extreme acid survival strategies. A surprising degree of variety was found between three related genera. The minimum growth pH of Salmonella typhimurium was shown to be significantly lower (pH 4.0) than that of either Escherichia coli (pH 4.4) or Shigella flexneri (pH 4.8), yet E. coli and S. flexneri both survive...
متن کاملsimultaneous detection of escherichia coli o157:h7, toxigenic vibrio cholerae, and salmonella typhimurium by multiplex pcr
background escherichia coli o157:h7, vibrio cholerae, and salmonella typhimurium are pathogenic bacteria found in contaminated water and food. no assay method is currently available on simultaneous detection or identification of all the three pathogens. our aim was to develop a rapid and reliable method for this purpose. materials and methods a protocol for sample collection, and a pcr procedur...
متن کاملSolar disinfection (SODIS) and subsequent dark storage of Salmonella typhimurium and Shigella flexneri monitored by flow cytometry.
Pathogenic enteric bacteria are a major cause of drinking water related morbidity and mortality in developing countries. Solar disinfection (SODIS) is an effective means to fight this problem. In the present study, SODIS of two important enteric pathogens, Shigella flexneri and Salmonella typhimurium, was investigated with a variety of viability indicators including cellular ATP levels, efflux ...
متن کاملAbundance of pathogenic Escherichia coli, Salmonella typhimurium and Vibrio cholerae in Nkonkobe drinking water sources.
In order to study the prevalence of enteric pathogens capable of causing infection and disease in the rural communities of Nkonkobe, bacterial isolates were collected from several surface water and groundwater sources used by the community for their daily water needs. By making use of selective culture media and the 20E API kit, presumptive Escherichia coli, Salmonella spp. and Vibrio cholerae ...
متن کاملVirulence of Shigella flexneri hybrids expressing Escherichia coli somatic antigens.
The genes controlling either Escherichia coli somatic antigen 8 or 25 were conjugally transferred to virulent Shigella flexneri 2a recipients to determine whether the aquisition of these antigens would affect the virulence of the resulting hybrid. A high proportion of such hybrids were found to be rough and hence were avirulent. Some smooth S. flexneri hybrids which replaced their native group ...
