Q. What are few mechanisms by which pathogenic bacteria cause diseases? And why is this knowledge important?

Pathogenic bacteria have characteristics called as virulence factors that help them to parasite their host. Some bacteria have cilium, fimbriae-like structures that attach the bacterial cell to the host tissue. There are bacteria specialized in intracellular parasitism, other bacteria secrete toxins, molecules that cause disease in some cases the bacterial population growth causes food contamination by toxins. In general, bacterial disease is caused by bacterial population growth with invasion and by bacterial toxins or destruction of tissues that contaminate the organism.
