Abstract
Antimicrobial resistance (AMR) is a serious concern globally in human and animal
health sectors and the menace is percolating to the aquaculture too. Since the aquaculture
sector is at the receiving end of the terrestrial run-off, the AMR detection strategy
would vary. Hence, AMR determination in the aquaculture sector strategy needs triangular
approaches viz. pathogens of aquatic animals, commensal bacteria of the aquaculture
ponds and food safety pathogens in harvested food fish. Farmed aquatic animals are
being transported as food material to distant places of intra, inter-countries and
continents. In this context, robust surveillance of AMR in microflora associated
with farmed aquatic animals remains an essential tool for identification and control
of its spread.
Despite numerous reviews that have been published for determining resistance in
pathogens of clinical importance, literature is scant on aquaculture and seafood
safety. The present review is oriented to illustrate the different approaches possible
for the identification of AMR especially in the aquatic animal pathogen, commensal
bacteria and seafood pathogens along with the molecular approach. The need of the
hour is rapid identification of resistance in the surveillance platforms, thereby
limiting the spread of the resistance and improving food security.
