Whole-Genome Sequences of Three Edwardsiella piscicida Isolates from Diseased Fish in South Korea

Abstract

Edwardsiella piscicida is a Gram-negative pathogen that is associated with edwardsiellosis in aquaculture systems worldwide. Here, we report the whole-genome sequences of three E. piscicida isolates derived from cultured fish in South Korea.

Development of a real-time recombinase-aided amplification assay for rapid and sensitive detection of Edwardsiella piscicida

“…Similar to other invasive pathogens, E. piscicida exhibits a preference for infiltrating host cells as a means to evade immune system detection and facilitate replication within both phagocytes and nonphagocytes, thereby contributing to its pathogenicity ( Xie et al., 2014 ; Zhang et al., 2016 ). In recent years, increasing number of E. piscicida isolates have been obtained from aquacultural environment ( Ferrari et al., 2022 ; Kim et al., 2022 ; Sugiura et al., 2022 ). Consequently, the development of a prompt and highly sensitive diagnostic technique for E. piscicida is of utmost importance in the prevention of outbreaks.…”

“…Currently, the identification of E. piscicida primarily depends on conventional techniques, including culture, PCR, or immune-testing ( Swain et al., 2001 ; Hong et al., 2009 ; Castro et al., 2010 ; Ferrari et al., 2022 ; Sugiura et al., 2022 ). While cultures offer undeniable proof of infection, their lengthy incubation period renders them impractical for clinical diagnosis, except for antimicrobial susceptibility analysis ( Kim et al., 2022 ; Sugiura et al., 2022 ). Various methods that rely on antibodies, such as enzyme-linked immunosorbent assay (ELISA), and quartz crystal microbalance (QCM) biosensor, have been developed for E. piscicida detection ( Swain et al., 2001 ; Hong et al., 2009 ).…”
