The Virulence Genes of Salmonella are Found in a Genomic

Question

The virulence genes of Salmonella are found in a genomic region referred to as pathogenicity
A) islands.
B) plasmids.
C) groups.
D) operons.
E) hotspots.

Accepted Answer

The virulence genes of Salmonella are found in a genomic region referred to as pathogenicity islands. These islands are clusters of genes that can be transferred horizontally and are responsible for the pathogenicity of the bacteria. Plasmids are extrachromosomal genetic elements that can also carry virulence genes, but they are separate from the main bacterial chromosome. Groups, operons, and hotspots do not specifically refer to genomic regions involved in pathogenicity.
