Aquest treball estudia la dinàmica poblacional de fags P22 en poblacions d'hostes que envelleixen, com a model de la resposta vírica a situacions d'estrès de l'hoste. Per tal d'analitzar les respostes adaptatives del virus a l'envelliment i conseqüent pèrdua d'eficiència replicativa de les cèl·lules hoste, hem estudiat la propagació vírica en poblacions hoste aïllades, utilitzant com a model un bacteriòfag mutant que no integra el seu DNA al cromosoma del bacteri.

This work studies the phage P22 spread dynamics in ageing bacterial populations, as a model of the viral response to host stress situations. In order to analyze the adaptative responses of the virus to the ageing, and consequent loss of replicative fitness of the host cells, we have explored the viral spread within isolated host populations, by using as a model a mutant bacteriophage unable to integrate its prophage DNA into the bacterial chromosome.
