Mechanisms by which the pathogenic bacteria cause diseases

Question

Name some mechanisms by which the pathogenic bacteria cause diseases? Why is this knowledge significant?

Answer 1

Pathogenic bacteria contain characteristics termed as virulence factors which help them to parasite their host. Various bacteria contain fimbriae, cilium-like structures which join the bacterial cell to the host tissue. There are bacteria specialized in an intracellular parasitism.

Other bacteria secrete toxins, molecules which cause disease; in some situations, the bacterial population growth causes food contamination through toxins. Usually, bacterial disease is caused by bacterial population growth by invasion and destruction of tissues or by bacterial toxins which contaminate the organism.
