Virulent forms of the bacterium staphylococcus aureus is a human pathogen, some strains of which cause “flesh-eating disease”. Earlier the antibiotic Penicillin was used to control this pathogen. After some years Penicillin was ineffective. Hence, a powerful antibiotic-Methicillin was used in treatments. Subsequently, Methicillin also became ineffective and the strains showed resistance to multiple antibiotics also called “multi-drug resistance”. Which one of the following statements regarding the development of multi-drug resistance is correct?
