How does Mupirocin affect in staphylococcal infection? I found this sentence confusing Transitor carriers of staphylococcal infections 70% because of mupirocin i/n. Mupirocin is drug which affects some way. I am not sure if the statement means inner neuronal. I am little confused by the abbreviation **i/n**. **What is the point of the sentence?**

This comes from the usage of the Mupirocin: Its an antibiotic, which is used topically (on the skin, its not taken in form of pills). It binds specifically to the isoleucyl t-RNA synthetase in gram positive bacteria and Streptoccus and Staphylococcus and is used to fight intranasally (that what i/n stands for) infections with these bacteria. It inhibts the introduction of isoleucine into proteins. More informations can be found here.
