Advances of community-acquired methicillin-resistant Staphylococcus aureus / 国际儿科学杂志

ABSTRACT

Methicillin-resistant Staphylococcus aureus (MRSA) is one of the major pathogens of the hospital infection.Its clinical features and drug-resisetance situations have always been concerned.But since the late 1990s,another class of MRSA has become a major concern worldwide as an emerging pathogen in the community.This new class of MRSA is called community-acquired MRSA (CA-MRSA).With the rapid development of the infection of CA-MRSA in 20 years,especially in the latest 3 years,CA-MRSA may be replacing the hospital-acquired MRSA strains(HA-MRSA) as one of the major pathogens in the hospital and the community as well.The characteristics of CA-MRSA are very different from those of HA-MRSA.This review summarizes the current studies of CA-MRSA on the epidemiology and the molecular characteristics.
