The potential novel bacteriophages against multidrug-resistant Edwardsiella tarda isolates from striped catfish Pangasianodon hypophthalmus.

ABSTRACT: The overuse of antibiotics in the aquaculture sector to prevent and treat the pathogen Edwardsiella tarda in striped catfish Pangasianodon hypophthalmus has led to the rapid emergence of multidrug-resistant (MDR) E. tarda isolates. Alternative strategies, such as phage therapy have been considered to control this MDR bacteria pathogen. We present here three lytic bacteriophages vB_EtA_WAG25P1, vB_EtA_WCT72P1, and vB_EtA_DT115P1 infecting E. tarda isolates, with their geographical origins from Mekong Delta, Vietnam. Morphological analyses combined with their genomic data indicate that the bacteriophages are classified to Autosignataviridae family in Autographivirales order. In the latent period of 35 min, the phage WCT72P1 and WAG25P1 had the burst size of about 45 virions and 61 virions pe
