Complete Genomic Sequences of Two Aeromonas hydrophila Isolates Derived from Diseased Fish in South Korea

Abstract

Aeromonas hydrophila is a Gram-negative pathogen that is associated with motile aeromonad septicemia in various fish species. Here, we report the complete genomic sequences of two A. hydrophila isolates derived from diseased fish in South Korea.

Gram-negative sepsis caused by a rare pathogenPhytobacter ursingii

“…Since this clarification, there has been a growing body of primary evidence that species within this genus, mainly P. diazotrophicus , have played a role in multidrug-resistant nosocomial infections 2–4. Despite this emerging understanding of P. diazotrophicus , there are currently no case reports describing P. ursingii infection.…”

“…This paucity of data may be representative of the difficulties of correct organism identification, more so than a lack of P. ursingii infections 4. Misidentification of Phytobacter spp is a known issue, with retrospective genotypical analysis of strains in GenBank having shown Phytobacter misclassified as Metakosakonia , Kluyvera , Enterobacter , Pantoea , Citrobacter and Enterobacteriaceae spp 3. Commonly employed phenotypical identification methods in clinical laboratories often misrepresent Phytobacter isolates as Pantoea spp, with as many as 100 reported Pantoae cases currently in question of being misidentified Phytobacter 4.…”

“…Phytobacter ursingii is a rarely encountered bacterium first categorised within the Enterobacteriaceae family in 2018 1. Since the discovery of the Phytobacter genus in 2008, there has been a growing body of evidence that species within this genus, mainly P. diazothrophicus , play a role in opportunistic nosocomial infections 2–4. Currently, there are no published case reports describing P .…”
