Antibiotics are a useful and convenient strategy for controlling bacterial infections, including those associated with S. agalactiae, of aquaculture species.
The excessive use of antibiotics has, however, led to
an increase in antibiotic-resistant bacteria and the subsequent transfer
of antibiotic-resistant plasmids to other aquaculture and human pathogens
(Sapkota et al., 2008). Antibiotic residues in aquaculture environments
and/or fish products can result in adverse effects on public
health and the environment
