- Q22. Why is it necessary for a person with bacterial infection to be told to take antibiotics at spaced intervalsto increase the concentration of antibiotic slowly to a level which is lethal to bacteriato maintain concentration of antibiotic in the body which is lethal to the bacteriato prevent the development of resistant strains of bacteriato select and kill the resistant strains of bacteria.30s
