Bacteriophage chi is a well-known phage that infects pathogens such as E. coli, Salmonella, and Serratia via bacterial flagella. To further understand its host-phage interaction and infection mechanism via host flagella, the genome was completely sequenced and analyzed. The phage genome contains 59,407-bp-length DNA with a GC content of 56.51 %, containing 75 open reading frames (ORFs) with no tRNA genes. Its annotation and functional analysis revealed that chi is evolutionarily very closely related to Enterobacter phage Enc34 and Providencia phage Redjac. However, most of the annotated genes encode hypothetical proteins, indicating that further genomic study of phage chi is required to elucidate the bacterial-flagellum-targeting infection mechanism of phage chi.
