Horizontal gene transfer has been recognized as one of the principal contributors to bacterial evolution and diversification. One of the mechanisms involved in this process is conjugative transfer of plasmids and Integrative ...

Members of the genus Acinetobacter possess distinct plasmid types which provide effective platforms for the acquisition, evolution, and dissemination of antimicrobial resistance structures. Many plasmid-borne resistance ...

Stable red astaxanthin-producing transformants were obtained after genetic transformation of two Phaffia rhodozyma mutants. A yellow mutant, accumulating β-carotene, and an albino mutant, accumulating phytoene, from P. ...

Bacteriophages have always been central for the evolution of bacteria. In this chapter, the transductive capacities of phages to mediate the transfer of either chromosomal or plasmid DNA among strains of lactic acid bacteria, ...

Vibrio parahaemolyticus O3:K6 pandemic strains recovered in Chile frequently possess a 42-kb plasmid which is the prophage of a myovirus. We studied the prototype phage VP58.5 and show that it does not integrate into the ...

Background: Lateral gene transfer plays a central role in the dissemination of carbapenem resistance in bacterial pathogens associated with nosocomial infections, mainly Enterobacteriaceae and Pseudomonas aeruginosa. Despite ...
