Biochemical Characterization of Sulfur Assimilation by Salmonella pullorum

Isolation and characterization of bacteriophages of Salmonella enterica serovar Pullorum.

In this study, 2 bacteriophages of Salmonella Pullorum were isolated using an enrichment protocol and the double agar layer method. They were named PSPu-95 and PSPu-4-116, respectively, against clinical isolates of Salmonella Pullorum SPu-95 and SPu-116. The host ranges of the 2 bacteriophages were determined by performing spot tests with 20 bacteria strains. Both bacteriophages had wide host r...

Synthesis of glutamic acid and alanine by Salmonella pullorum.

The literature reveals many references to transamination by bacteria. Two well substantiated works are those of Cutinelli (1945) and Lichstein and Cohen (1945). Goodlow, Mika, and Braun (1950) and Altenbern and Housewright (1951) have demonstrated synthesis of alanine by BruceUa abortus involving this method. Altenbern and Housewright also showed that their organism was capable of direct or red...

Infection of Salmonella pullorum, Salmonella newington or Salmonella enteritidis in laboratory rats by oral inoculation.

Thermolabile Sulfite Reductase from Salmonella pullorum'

The biochemical basis for sulfite accumulation by sulfate-using revertants of Salmonella pullorum was determined. All of the sulfate-using mutants isolated from wild-type S. pullorum accumulated sulfite when grown at 37 but not at 25 C. The specific activity of reduced nicotinamide adenine dinucleotide (NADPH)-dependent sulfite reductase (H2S-NADP oxidoreductase, EC 1.8.1.2) and of reduced meth...

Study on phenotypic characteristics of Salmonella gallinarum and Sallmonella pullorum isolates based on biochemical and antimicrobial susceptibility tests in Iran

Salmonellosis is a very important disease of avian species because of its huge economic impact, worldwide distribution and difficulty posed in its control. Fowl typhoid and pullorum disease, is caused by Salmonella enterica subsp enterica serovar Gallinarum biovar Gallinarum and Pullorum. The purpose of this study was to investigate the biochemical characteristics and antimicrobial susceptibili...
