“…Chi phage serves as the prime example of a group of closely related Chi-like phages (Moreno Switt et al, 2013;Grose and Casjens, 2014;Hendrix et al, 2015), most of which infect Salmonella enterica serovars, but some of which are reported to be specific for Enterobacter cancerogenous (Kazaks et al, 2012) or Providencia stuartii (Onmus-Leone et al, 2013). Diverse flagellotropic phages have been identified to infect a range of bacterial species including Aeromonas-phage PM3 (Merino et al, 1990), Agrobacterium-phages 7-7-1, GS2 and GS6 (Bradley et al, 1984;Kropinski et al, 2012), Asticcacaulis and Caulobacterphages ϕAcS2, ϕAcM4, ϕCp34, ϕCb13 and ϕCbK and ϕ6 (Jollick and Wright, 1974;Fukuda et al, 1976;Pate et al, 1979;Guerrero-Ferreira et al, 2011), Bacillus-phages AR9, 3NT, PBS1, SP3 and PBP1 (Lovett, 1972;Shea and Seaman, 1984;Vieira et al, 1989), Campylobacter-phage F431 (Baldvinsson et al, 2014) Proteus-phage PV22 (Zhilenkov et al, 2006) and Pseudomonas-phage ϕCTX (Geiben-Lynn et al, 2001). Interestingly, for ϕCb13 and ϕCbK, targeting the flagellum of their host is performed by a flexible filament emanating from its capsid rather than the distal tail complex observed in Chi phage for example (Guerrero-Ferreira et al, 2011).…”
