virulent phage

a BACTERIOPHAGE which, following phage replication in the cell, results in LYSIS of the host. It cannot be integrated into the chromosome of the host, unlike a TEMPERATE PHAGE.

It was found that the virulent phages were able to lyse the host bacterium by developing clear circular zones with average plaque diameter of 5-7mm.

Isolation and Characterization of Lytic Coliphages from Sewage Water

As the phage filtrates were not purified, more species of phages may have been present, including temperate phages that did not lyse the bacteria or virulent phages with longer latency periods and therefore did not have the time to produce plaques during the 24 h incubation period.

As the enriched phage filtrates produced plaques in all the bacterial strains isolated, this study provides promising results on the efficacy of virulent phages in infecting bacteria present in sea turtle environments.

However, the phage is highly host specific and is not effective against other clinical isolates included in our study which suggests that more virulent phages are yet to be discovered in the future.

The team has a phage bank with more than 100 phages, and from that they selected four virulent phages (known to the researchers as Sano, Salvo, Prado and Paz) based on their physical and genetic characteristics.
