Antimicrobial resistance genes in marine bacteria and human uropathogenic E scherichia coli from a region of intensive aquaculture
Antimicrobials are heavily used in C hilean salmon aquaculture. We previously found significant differences in antimicrobial‐resistant bacteria between sediments from an aquaculture and a non‐aquaculture site. We now show that levels of antimicrobial resistance genes ( ARG ) are significantly higher...

description | Antimicrobials are heavily used in
C
hilean salmon aquaculture. We previously found significant differences in antimicrobial‐resistant bacteria between sediments from an aquaculture and a non‐aquaculture site. We now show that levels of antimicrobial resistance genes (
ARG
) are significantly higher in antimicrobial‐selected marine bacteria than in unselected bacteria from these sites. While
ARG
in tetracycline‐ and florfenicol‐selected bacteria from aquaculture and non‐aquaculture sites were equally frequent, there were significantly more plasmid‐mediated quinolone resistance genes per bacterium and significantly higher numbers of
qnrB
genes in quinolone‐selected bacteria from the aquaculture site. Quinolone‐resistant urinary
E
scherichia coli
from patients in the
C
hilean aquacultural region were significantly enriched for
qnrB
(including a novel
qnrB
gene),
qnrS
,
qnrA
and
aac(6′)‐1b

qnrA1
,

and
qnrS1
in quinolone‐resistant
C
hilean
E

and
C
hilean marine bacteria were identical, suggesting horizontal gene transfer between antimicrobial‐resistant marine bacteria and human pathogens. |
