Sentences with phrase «virulent than its antibiotic»

Not exact matches

The evolution of such resistance does not cause the organism to be more intrinsically virulent than strains of Staphylococcus aureus that have no antibiotic resistance, but resistance does make MRSA infection more difficult to treat with standard types of antibiotics and thus more dangerous.

Researchers have found that just five strains are overwhelmingly the culprits in more than 3000 samples of resistant S. aureus collected from patients around the world; the small number suggests that relatively few strains can easily develop resistance to antibiotics, allowing scientists to focus on these few and determine what makes them so virulent.

Skov adds: «I fear that if we don't get antibiotic use in livestock under control, then new, more virulent strains of livestock - associated MRSA will emerge that pose a much greater threat to human health than what we are currently facing.»
