MRSA USA300: Flesh-eating Bug Commonly Spread On Buses And Trains

The community-acquired bacteria has evolved further, and is able to maintain a higher level of toxicity while also resisting treatment from antibiotics, making it a much larger problem- Journal of Infectious Diseases

The highly infectious strain, MRSA USA300 , is resistant to many front-line antibiotics and has now been discovered in public places, such as buses and trains. Though people can avoid direct contact with a sneeze or cough, Professor Thomas from the University of Birmingham highlights the possibility of becoming infected from touching surfaces.  In this way, every day settings and public surfaces act as viable means to contract an infection.  According to the Daily Mail, MRSA USA300 has been called “flesh-eating” due to its ability to lead to large skin boils, abscesses, blood poisoning and even fatal forms of pneumonia that destroy lung tissue.

The Daily Mail reports Dr. Ruth Massey of the Department of Biology and Biochemistry at the University of Bath warns people to take care in guarding against MRSA, especially strains that carry genes for Panton-Valentine leukocidin (PVL). This cytotoxin can destroy white blood cells and cause extensive tissue necrosis. According to Massey, more than a thousand PVL positive-community-acquired cases were reported in England last year. Of these, 1 in 5 were caused by the USA300 strain. Read More
