Abstract: Antimicrobials have been widely used in veterinary medicine for disease
treatment, disease prevention, and growth promotion. Although, the mechanisms about
in-feed additives use are still not completely understood, it is accepted that its use
improves feed efficiency by reducing the microbial load in the intestinal tract, thereby
reducing the pressure on the immune system and increasing energy availability for the
animal. However, disruption to commensal bacterial communities by antibiotics in some
cases can increase the gut colonization by pathogenic bacteria. In this sense, the aim of
this study was to evaluate the Escherichia coli antibiotic resistance and the gut
microbiota profile from pigs raised in Brazilian farms with different in-feed
antimicrobials protocols. Pigs from four farms with distinct antibiotic usage, including
one farm that used no antibiotics, were followed from weaning to finishing, and the
frequency of antimicrobial resistance and gut bacterial profile by 16S rRNA gene
sequencing were evaluated. The gut microbial community structure was the same
among all groups of pigs despite different antibiotic use on the farms; however, the
antimicrobial resistance profiles of E. coli isolates were different between groups. One
farm administered seven antibiotics at different times, and E. coli isolates from these
pigs showed higher frequency of resistance and multidrug resistance as compared with
samples from the farm that did not administer in-feed antimicrobials. The phenotypes
included resistance to drugs considered critically important antimicrobial agents in
veterinary medicine (ampicillin, ciprofloxacin, florfenicol, sulfonamide and
tetracycline) as well as one highly important antibiotic in human medicine (colistin).
Resistant E. coli strains were screened for the presence of the mcr-1 gene by PCR. The
colistin-resistant strains were positive for the presence of the mcr-1 gene. These results
suggest that although different antibiotic uses on-farm might not impact microbial
community structure, it does impact bacterial functions, namely antibiotic resistance.
Our results show that prudent use of antimicrobials is important for decreasing selective
pressure for antibiotic resistance gene evolution MenosAbstract: Antimicrobials have been widely used in veterinary medicine for disease
