HIGH-THROUGHPUT METHODS TO CHARACTERIZE PHAGE RECEPTORS AND RATIONAL FORMULATION OF PHAGE COCKTAILS

摘要

The present invention provides for a method for screening for gene function for a bacteriophage, the method comprising: (1) (a) providing one or more host organism, such as a species or strain, libraries, (b) providing randomly barcoded transposon sequencing (such as RB-TnSeq), and (c) screening for loss-of-function (LOF) mutant phenotypes; or (2) (a) providing one or more DNA barcoded overexpression strain libraries (such as Dub-seq) using DNA of the host organism and/or phage, and (b) screening for gain-of-function (GOF).
