Question

How can bacteria control their pathogenicity?

Answer 1

Pathogenicity in bacteria:

1. Any micro-organism that can cause disease or some infection is called a pathogen.
2. The ability of any pathogen to cause disease is called pathogenicity.
3. The pathogenicity in any organism is determined by its virulence factors.
4. For the expression of their virulence genes, the bacteria use alternative sigma factors and two-component signal transduction systems.
5. These methods are referred to as common regulatory mechanisms.
6. The genomes of pathogenic strains show some extra genes that code for their virulence factors.
