C22 MRSA- the Superbug

The researchers identified C22 as the dominant strain of MRSA which develops and maintains multi-drug resistance and which adapts to persist on hospital surfaces.

According to author Dr. Lindsay, “studying the dynamic of how MRSA bacteria strains  evolve in hospitals in response to infection control and antibiotic prescribing, is essential to the process of determining which strains are likely to have the best long-term outcomes.”

The bacteriophage is a potential anti-MRSA measure.

A bacteriophage is a virus that kills bacteria and could counter intractable MRSA infections in patients.

Dr. Lindsay told Decoded Science that, “Bacteriophage has potential to combat MRSA, but still needs substantial development before a product is likely to reach the market.”

MRSA Study Highlighted Reduced Infection Rates

This study examined whether improved infection control measures contributed to this decrease in MRSA infection. However, during a four-year period, the only major reduction in MRSA infection rates coincided with the reduction in ciprofloxacin prescriptions. In fact, the only measure that appreciably reduced deadly MRSA infection was the reduction of prescription antibiotics.
