Multilocus sequence typing scheme for the characterization of 936-like phages infecting Lactococcus lactis.

ABSTRACT: Lactococcus lactis phage infections are costly for the dairy industry because they can slow down the fermentation process and adversely impact product safety and quality. Although many strategies have been developed to better control phage populations, new virulent phages continue to emerge. Thus, it is beneficial to develop an efficient method for the routine identification of new phages within a dairy plant to rapidly adapt antiphage tactics. Here, we present a multilocus sequence typing (MLST) scheme for the characterization of the 936-like phages, the most prevalent phage group infecting L. lactis strains worldwide. The proposed MLST system targets the internal portion of five highly conserved genomic sequences belonging to the packaging, morphogenesis, and lysis modules. Our MLST sche
