Phage therapy
Bacteriophage therapy, the use of viruses that infect bacteria as antimicrobials, has been championed as a promising alternative to conventional antibiotics. Although in the laboratory bacterial resistance against phages arises rapidly, resistance so far has been an only minor problem for the effectiveness of phage therapy. Resistance to antibiotics, however, has become a major issue after deca...
متن کاملRole of temperate phage in determining lytic phage sensitivity and serotype of Vibrio cholerae.
The effect of lysogenization with five temperate phages from various sources on serotype and lytic phage sensitivity was investigated in six cultures of Vibrio cholerae of both classical and El Tor biotypes. No changes in serotype or in classical phage sensitivity in the classical biotype were observed. Four of the temperate phages were homoimmune and induced resistance to one of the El Tor typ...
متن کاملWell-temperate phage: optimal bet-hedging against local environmental collapses
Upon infection of their bacterial hosts temperate phages must chose between lysogenic and lytic developmental strategies. Here we apply the game-theoretic bet-hedging strategy introduced by Kelly to derive the optimal lysogenic fraction of the total population of phages as a function of frequency and intensity of environmental downturns affecting the lytic subpopulation. "Well-temperate" phage ...
متن کاملComplete genome of temperate phage ENT39118 from Cronobacter sakazakii.
Cronobacter sakazakii infection is particularly harmful to infants, and putative virulence factors of prophage origin have been identified in C. sakazakii. In this study, the phage ENT39118 was isolated from wild-type C. sakazakii; it belongs to the family Siphoviridae. The genomic sequence of phage ENT39118 was composed of circular double-stranded DNA with a length of 39,012 bp. The sequence o...
متن کاملRegulating phage therapy
I n a note published in The Lancet in December 1915, Frederic Twort described the discovery of an infectious, filterable agent that causes the glassy transformation and eventual killing of bacteria, now identified as Staphylococcus hyicus [1]. Two years later, Félix d’Herelle independently described an invisible microbe antagonistic to dysentery bacilli in a note to the Comptes Rendus de l’Acad...
