Response to Comment on "The role of wildlife (wild birds) in the global transmission of antimicrobial resistance genes"

Dear Editor,

Since our first identification of plasmid-mediated colistin resistance genein 2015 (Liu et al., 2016), it has been described in human clinics, domestic animals, foods, and the environment worldwide (Schwarz & Johnson, 2016). Although it is still rare, the emergence ofin wild animals is of great concern. We summarized two previous reports onin wild birds from Lithuania and Argentina to describe its emergence and characteristics in wildlife and highlight the potentially important role of wild animals, particularly birds, in its global transmission (Wang et al., 2017). The first detection ofin wildlife in Asia was identified in an extended-spectrum β-lactamase-producingstrain isolated from Eurasian coot (), which was located on a ~63 kb IncI2 plasmid, frequently associated with the global transmission of(Mohsin et al., 2016). The description ofin wild birds in Asia is very important to better understand the role that wild birds may play in the global spread of, and should have been summarized in our recent review. However, our review only summarized articles published up to December 2016, and as such the then unpublished report on CTX-M-15-producingin wild birds in Pakistan (Raza et al., 2017) was not included.
