Bacteriophages as selective agents for enriching target bacteria

Abstract

Compositions containing bacteriophages and methods of using bacteriophages in microorganism detection assays and microbial growth and plating media are disclosed. The lytic ability of these phages to control the growth of non-target populations provides superior sensitivity and specificity to detection assays and reduces false negative and false positive results. The removal of contaminating bacteria reduces the microbial competition for nutrients in the growth media thereby increasing the efficiency and productivity of the culture. The phage treatment of the sample increases the proportion of target microorganisms in the sample over contaminating bacteria thereby requiring less time for enrichment to obtain a significant signal improving overall signal to noise ratio in assays and providing for higher yield of end product in microbiological production systems.
