... however, a penicillin and methicillin resistant Staphylococcus aureus (MRSA) strain was described. Subsequently, vanomycin has been used in the fight against MRSA but recently vanomycin resistant S. Aureus (VRSA) have also been identified. Unlike MRSA, VRSA is not so widespread.1 S. Aureus is capable of causing a wide range of infections including skin and wound infections and bacteraemia, thus, untreatable MRSA infections pose a particular risk to the more immuno-compromised, such as critically ill patients.1 Unfortunately, we humans have contributed ourselves in making antibiotic resistance into a health risk. Overuse of antibiotics in the past sixty years have led to the emergence of antibiotic resistant infectious strains of various bacteria. This occurs because the death of susceptible bacteria confers a favourable selection pressure, and the resistant bacteria become the dominant species. This phenomenon is aided by two factors: first, the rapid bacterial proliferation rate of twenty minutes and second, the ...
