Draft Genome Sequence of the Host-Restricted Salmonella enterica Serovar Abortusovis Strain SS44
Salmonella enterica serovar Abortusovis is a pathogen strictly adapted to ovines, in which it causes abortion. To enhance our understanding of this pathogen, we assembled the first draft sequence of an S. Abortusovis genome (strain SS44). The obtained genomic data might facilitate the study of S. enterica evolution and host adaptation.
متن کاملTransposition of the heat-stable toxin astA gene into a gifsy-2-related prophage of Salmonella enterica serovar Abortusovis.
The horizontal transfer and acquisition of virulence genes via mobile genetic elements have been a major driving force in the evolution of Salmonella pathogenicity. Serovars of Salmonella enterica carry variable assortments of phage-encoded virulence genes, suggesting that temperate phages play a pivotal role in this process. Epidemic isolates of S. enterica serovar Typhimurium are consistently...
متن کاملCross-protection of Salmonella abortusovis, S. choleraesuis, S. dublin and S. gallinarum in mice induced by S. abortusovis and S. gallinarum: bacteriology and humoral immune response.
Cross-protection induced by primary infection with Abortusovis and Gallinarum was examined against challenge injection with these Salmonella serotypes as well as with Dublin and Choleraesuis, the other virulent serotypes. Abortusovis induced efficient protection against the other Salmonella. Gallinarum was ineffective against Choleraesuis. Even with low multiplication in mice, the Gallinarum J9...
متن کاملIdentification of Salmonella abortusovis by PCR amplification of a serovar-specific IS200 element.
Field and collection isolates of Salmonella abortusovis carry one IS200 element in a distinct chromosome location. IS200 is not found in the corresponding region of the chromosome of other Salmonella serovars. Sequencing of the boundaries of the S. abortusovis-specific IS200 insertion permitted the design of primers for the amplification of this IS200 element by PCR. Isolates of S. abortusovis ...
متن کاملA molecular study of the Salmonella enterica serovars Abortusovis, Typhimurium, and Enteritidis
Th is study presents a molecular analysis of 3 important human and animal serovars of Salmonella: Typhimurium, Enteritidis, and Abortusovis. We also provide information that can be applied in the surveillance of salmonellosis. Over the course of 3 decades, 90 isolates were collected, with 30 isolates representing each type of serovar. In addition to conventional serotyping, serovars were confi ...
