Abstract
The use of antibiotics in aquaculture may cause development of antibiotic resistance among pathogens infecting cultured animals and humans. Therefore, the phages were isolated from the culture environment that can infect the pathogen and resistant bacteria. In this study, there were vibriophage and antibacterial phage isolated
from CLOZ andSCKF. The small and circle plaque of vibriophage could become
striking by decrease in top agar percentage. The electron micrographs of vibriophage
and antibacterial phage belonged to the Podoviridae and Myroviridae family. The
phages genome could be cut by HidinIII. The different size fragments were compared
and matched to similar genome size of phages from NCBI. For the result, vibriophage may belong to the Picovirinae in Podoviridae. The antibacterial phage would be classified into either Mu-like viruses or unclassified Myoviridae. In the infecting test with (103 PFU/ml), the vibriophage lysing the host cell was not evident. Then, infecting with ϕA, ϕ20 and ϕ70 107 PFU/ml), the ϕA could lyse the cell and test the lowest OD after two hours by infecting. ϕ20 lysed the cell at exponential phase and antibacterial phage ϕ70 could lysed the host cell at different ages after six hours by infecting. A could lyse the cell and test the lowest OD after two hours by infecting. ϕ20 lysed the cell at exponential phase and antibacterial phage ϕ70 could lysed the host cell at different ages after six hours by infecting.
