Abstract

New sequencing studies of the nonsegmented dsRNA genome of penaeid shrimp infectious myonecrosis virus (IMNV), a tentatively assigned member of the family Totiviridae, identified previously unread sequences at both genome termini in three previously analyzed IMNV strains, one from Brazil (the prototype strain of IMNV) and two from Indonesia. The new sequence determinations add >600 nt to the 5′ end of the genomic plus strand of each strain, increasing the length of the 5′ nontranslated region to at least 469–472 nt and the length of the upstream open reading frame (ORF1) translation product by at least 48 aa. These new findings are similar to recent ones for two other IMNV strains (GenBank KF836757.1 and KJ556923.1) and thereby corroborate important amendments to the full-length IMNV genome sequence.
