I thought the same with the NIH article, but the date on that one is May and the nature paper is October-- unless I am confused.

Cesar & Nunez (October) is basically just a summary of Liu et al (May).

Is from may. The Wiki article on this anti-biotic has sources from then.

This link is a better and not-paywalled version from then:
