“…Some Salmonella strains have a narrow host range, such as Salmonella enterica serovar Typhi, that causes disease in humans only, while other strains, such as Salmonella enterica serovar Typhimurium, cause infections in a wide range of animal species including mice, poultry, pigs, sheep, cattle, horses, and humans (20,62). S. enterica serovar Typhimurium human gastroenteritis is initiated by the colonization of the intestinal epithelium followed by invasion and destruction of M cells and enterocytes, which disrupts the integrity of the mucosal surface and allows access to the underlying tissue (33,34).…”

Salmonella enterica Serovar Typhimurium Requires the Lpf, Pef, and Tafi Fimbriae for Biofilm Formation on HEp-2 Tissue Culture Cells and Chicken Intestinal Epithelium

et al. 2006

Recent work has demonstrated that Salmonella enterica serovar Typhimurium forms biofilms on HEp-2 tissue culture cells in a type 1 fimbria-dependent manner. To investigate how biofilm growth of HEp-2 tissue culture cells affects gene expression in Salmonella, we compared global gene expression during planktonic growth and biofilm growth. Microarray results indicated that the transcription of ϳ100 genes was substantially altered by growth in a biofilm. These genes encode proteins with a wide range of functions, including antibiotic resistance, central metabolism, conjugation, intracellular survival, membrane transport, regulation, and fimbrial biosynthesis. The identification of five fimbrial gene clusters was of particular interest, as we have demonstrated that type 1 fimbriae are required for biofilm formation on HEp-2 cells and murine intestinal epithelium. Mutations in each of these fimbriae were constructed in S. enterica serovar Typhimurium strain BJ2710, and the mutants were found to have various biofilm phenotypes on plastic, HEp-2 cells, and chicken intestinal tissue. The pef and csg mutants were defective for biofilm formation on each of the three surfaces tested, while the lpf mutant exhibited a complete loss of the ability to form a biofilm on chicken intestinal tissue but only an intermediate loss of the ability to form a biofilm on tissue culture cells and plastic surfaces. The bcf mutant displayed increased biofilm formation on both HEp-2 cells and chicken intestinal epithelium, while the sth mutant had no detectable biofilm defects. In all instances, the mutants could be restored to a wild-type phenotype by a plasmid carrying the functional genes. This is the first work to identify the genomic responses of Salmonella to biofilm formation on host cells, and this work highlights the importance of fimbriae in adhering to and adapting to a eukaryotic cell surface. An understanding of these interactions is likely to provide new insights for intervention strategies in Salmonella colonization and infection.

“…Scott (1939-40) also records the isolation of S. thompson from the mesenteric glands of healthy pigs at slaughter. Salmonella organisms, other than S. pullorum and S. gallinarum, are common in poultry, and in a discussion on the occurrence and distribution of Salmonella types in the United States, Edwards & Bruner(1943)enumerate forty-two strains derived from poultry. Out of a total of 3090 cultures examined by Edwards & Bruner, S. thomppoultry apart from the single case reported by Edwards & Bruner (1943).…”

During the years 1943 and 1944 S. thompson, not hitherto reported in poultry in this country, has been isolated on forty-four occasions from thirty-one outbreaks in chicks, and two outbreaks in ducklings. Two extensive outbreaks are described in detail, and the epidemiology of the disease and its possible importance to public health are discussed.We wish to record our appreciation of the help given by the late Dr R. B. Haines and by Miss E. M. L. Elliot, Ministry of Food, Department of Pathology, Cambridge, in the identification of some of the strains isolated from outbreak no. 1, and for the gift of a stock strain of S. thompson which was used in the typing of strains 2768 and 3845.We also wish to thank Dr Joan Taylor, Emergency Public Health Laboratory, Oxford, for supplying us with factor 5 (absorbed) serum.

“…These workers believed that the counts were low because the pans were washed thoroughly with pressure sprays on the return trip. Only one isolation of Salmonella was made by Galton et al (1955) (Geiger, 1923» Frank, 1940Puchs, 1941 (Edwards et , 1948;Goresline, 1948;Hinshaw and McNeil, 1948;Hinshaw, 1949;Pelsenfeld, 1951» Quist, 1962Kampelmacher, I963 of the salmonellas isolated were S. typhimurium.…”
