Background:: Non-typhoidal Salmonella enterica (NTS) in seafood is an important human health concern.
An emerging strain of NTS serovar Infantis carrying a megaplasmid pESI and resistant to multipe drugs
has been responsible for frequent food-borne human infections worldwide.
Methods:: S. enterica strain JS5 was isolated from a sample of shrimp from the retail market on XLD agar
after enrichment in the RV medium. The genomic DNA was isolated and sequenced using the Illumina
platform. The draft whole genome sequence of Salmonella Infantis JS5 revealed the presence of a plasmid.
Results:: The genome size was 4,977,731 bp with 4663 open reading frames. The bacterium harboured
a megaplasmid similar to the pESI plasmid reported in the emerging S. Infantis. The 285 kb plasmid
contained the characteristic genes of the pESI plasmids, such as the mercury operon, yersiniabactin
siderophore operon, fimbriae, toxin-antitoxin systems and the hypothetical protein backbone. The antibi-
otic resistance genes tet(A), dfrA14, aadA, qacEdelta1, and sul1 were detected. To the best of our knowl-
edge, this is the first report on pESI plasmid carrying S. Infantis from India.
