Abstract

Aeromonas phage AHP-1 was originally isolated from crucian carp (Carassius carassius) tissue. It was able to infect Aeromonas hydrophila and A. salmonicida. Genome sequence analysis revealed a 218,317-bp-long linear genome with an overall G + C content of 47.9%, 315 open reading frames (ORFs), and 25 tRNA sequences. Its genome was found to contain 67 unique ORFs (21.26%) that did not show any homology to previously characterized proteins. A comparative genome analysis suggested that its closest neighbors are unclassified phages belonging to the genus Tequatrovirus of the subfamily Tevenvirinae.
