Solution

Pathogenic and non-pathogenic strains of bacteria:

  1. The bacteria that cause diseases are called pathogenic bacteria, while certain bacteria do not cause any diseases and are called non-pathogenic bacteria.
  2. In the genome of pathogenic bacteria virulence genes are present that cause infections and diseases.
  3. Pathogenic bacteria produce certain toxins and thus cause harm to the cells where they are residing.
  4. Non-pathogenic bacteria are devoid of any virulence genes and thus, they do not cause any infection or diseases.
  5. Pathogenic bacteria cause diseases like food poisoning, meningitis, urinary tract infections, etc.
