Why Latest MRSA News Proves We Cannot Rely on Antibiotics Alone

Posted by Tru-D SmartUVC 11.19.15

A recent study found that one of the most common antibiotics used to treat Methicillin-resistant Staphylococcus aureus, or MRSA, may unintentionally activate the body’s own pathogen-defense system and worsen this type of skin infection.

Typically, physicians use a beta-lactam antibiotic to treat staph infections. And, the study clearly showed that mice that were infected with MRSA and then treated with beta-lactam antibiotics saw worse infection cases. Researchers did note that while this outcome was very clear in mice, the correlation is more difficult to detect in humans because of compounding factors.


However, MRSA is only one form of staph infection, and it may take health care providers several days to diagnose the correct form, costing them valuable time in the healing process if they are administering antibiotics that can potentially cause more harm. While more research is needed to alter guidelines on treatments for staph and MRSA, this does tell us that we may not have as many effective antibiotics in our arsenal as needed to fight health care-associated infections.

And, this further reinforces the fact that we cannot rely on antibiotics alone. Health care leaders must have a multi-layered approach to infection prevention and control, outside of the antibiotics they administer to patients, and environmental hygiene is an important component that cannot be overlooked.

In 2010, the study “Room Decontamination with UV Radiation” showcased the effectiveness of Tru-D’s measured germicidal UV dose in eliminating nosocomial pathogens found in contaminated hospital rooms. By measuring the MRSA counts in patient rooms before and after patient occupation, researchers from this study concluded that Tru-D was effective in eliminating these deadly pathogens. Specifically, Tru-D destroyed vegetative bacteria on contaminated surfaces both in direct sight, as well as behind objects.

Furthermore, Tru-D’s measure germicidal UV dose was validated in the CDC-funded study “Benefits of Enhanced Terminal Room Disinfection,” proving that Tru-D can reduce the risk of infection caused by multi-drug resistant organisms by 30 percent. Researchers specifically studied rates of MRSA, VRE, C. difficile and MDR Acinetobacter to determine this statistically sound evidence.
