Abstract

Twenty-seven (0.51%) USA300 isolates were identified from a pool of 5308 meticillin-resistant Staphylococcus aureus (MRSA) isolates collected in Taiwan between 1995 and October 2015, including 12 infecting isolates from 10 patients. The first two isolates were identified in 2005, and 23 isolates have been collected since 2010. Phylogenetic analysis revealed that all the local isolates were closely related to those in North America, and there was a clade consisting of 13 local isolates from 10 patients. MRSA USA300 existed in Taiwan in 2005 or earlier, with increasing identification since 2010. Local transmission of USA300 has occurred in Taiwan after importation from North America.

CRISPR & Staphylococcus

CRISPR-Cas system enables the editing of genes to create or correct mutations. Staphylococci are associated with life-threatening infections in hospitals, as well as the community. Here is the latest research on how CRISPR-Cas system can be used for treatment of Staphylococcal infections.
