Task: Answer Verification
Input (English): Question: Is epidemic MRSA clone ST22-IV more resistant to multiple host- and environment-related stresses compared with ST228-I?
Answer: Our results support our hypothesis that ST22-IV has a fitness advantage over ST228-I. This fitness advantage could have allowed ST22-IV to displace ST228-I without acquiring additional resistances and could help explain its epidemic success in hospital settings and its spread in Europe and beyond.
Output (English): yes
