Journal ArticleDOI
Reproducibility and correlation study of three deoxyribonucleic acid hybridization procedures
TL;DR: At 75°C, RBR obtained with S1-DE81 and HA methods are comparable without any transformation of the data, and a curvilinear relationship was found between RBR data obtained withS1-TCA and HA procedures at 60 or75°C.
Journal ArticleDOI
Virulence and vaccine potential of Salmonella typhimurium mutants deficient in the expression of the RpoS (sigma S) regulon.
TL;DR: The results demonstrate that rpoS not only controls the growth and persistence of S. typhimurium in deep lymphoid organs, but also plays a role during the initial stages of oral infection.
Journal ArticleDOI
Polynucleotide sequence relatedness among motileAeromonas species
TL;DR: Any decision to delineate species in terms of DNA hybridization groups must await a phenotypic basis for their separation, as each species contains more than one hybridization group.
Journal ArticleDOI
Virulence-associated plasmids of Salmonella serotype Typhimurium in experimental murine infection.
TL;DR: It is demonstrated that a 60-Mdal plasmid in Typhimurium strains is necessary to ensure colonization of spleen and liver of experimentally infected mice.
Journal ArticleDOI
Identification of a non-haem catalase in Salmonella and its regulation by RpoS (sigmaS).

TL;DR: The identification and functional analysis of katN, a gene encoding a non‐haem catalase of Salmonella enterica serotype Typhimurium, revealed that it increased the H2O2 resistance of unadapted cells in the exponential phase and of rpoS mutants in stationary phase, suggesting it may contribute to hydrogen peroxide resistance inSalmonella in certain environmental conditions.
