Abstract
Streptococcus iniae is a major fish pathogen that produces invasive infections that result in economic losses in aquaculture. In this study, the draft genome sequence of Streptococcus iniae strain IUSA-1, isolated from a natural outbreak affecting gilthead sea bream (Sparus aurata) and red porgy (Pagrus pagrus), is presented.
Highlights
Streptococcus iniae is a major fish pathogen that produces invasive infections that result in economic losses in aquaculture
Gilthead sea bream and red porgy affected by S. iniae IUSA-1 showed clinical signs of hemorrhagic septicemia, lethargy, anorexia, abnormal swimming, exophthalmia, and sudden death, with mortality rates over 25% in red porgy and 10% in gilthead sea bream, and with acute meningoencephalitis as the main lesion
The genome of S. iniae IUSA-1 is composed of 2.22 Mb, with an average GϩC content of 36.3%
Summary
Streptococcus iniae is a major fish pathogen that produces invasive infections that result in economic losses in aquaculture. Streptococcus iniae is an important Gram-positive bacterium that is associated with acute and chronic mortality in marine and continental aquaculture [1], affecting more than 30 fish species [2, 3, 4], and has been reported in Asia, Australia, America, and Europe [3, 4]. S. iniae causes invasive infections, producing high economic losses in aquaculture.
