BACKGROUND Salmonella spp. is the major bacterial pathogen in poultry and is responsible for significant economic losses of the poultry industry in many parts of the world. Among Salmonella spp., Salmonella gallinarum and Salmonella. pullorum are the most common causative agents of chicken salmonellosis resulting in high mortality and morbidity. OBJECTIVES The aim of this study was to identif...

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...

Analyses were made to determine the amino acid composition of the cell-wall proteins of Salmonella pullorum, S. senftenberg 775W, S. derby, and Escherichia coli. These proteins consist of the usual 18 amino acids found in most proteins with diaminopimelic acid in addition. Quantitative determination of these amino acids showed that their amounts were similar.

Pullorum disease causing acute septicemia and mortality in adult brown chickens was diagnosed in a small-farm chicken flock in Iowa. Also, Salmonella Pullorum was isolated from the intestine of one of four rats trapped on this index farm. Tracing movements of spent hens from the index farm resulted in identification of a second infected flock on a contact farm. Poultry on the contact farm were ...

BACKGROUND Salmonella enterica serovar Pullorum (S. Pullorum) causes Pullorum disease (PD), a severe systemic disease of poultry and results in considerable economic losses in developing countries. In order to develop a safe and immunogenic vaccine, the immunogenicity and protective efficacy of S06004ΔSPI2, a Salmonella pathogenicity island 2 (SPI2) deleted mutant of S. Pullorum was evaluated i...

Salmonella enterica serovar Pullorum is a chicken-adapted pathogen, causing pullorum disease. Its strict host adaptation has been suspected to result in gene decay. To validate this hypothesis and identify the decayed genes, we sequenced the complete genome of S. Pullorum RKS5078. We found 263 pseudogenes in this strain and conducted functional analyses of the decayed genes.

Background: DNA amplification method has been developed for identifying and discriminating Salmonella serovars, using specific primers at the genus and serovar levels and to identify the S. Enteritidis, S. Dublin, S. Gallinarum and S. Pullorum. Objectives: This study was conducted for molecular identification and discrimination among some important Salmonella serovars. Methods: Fifty isolates o...

In the course of various investigations of microorganisms in spray-dried whole-egg powder, it became apparent that further information concerning the nutrition and metabolism of the genus Salmonella was essential. A survey of the literature revealed that little attention has been given this genus in this respect. Such information would be of value in improving the present methods of isolation a...
