Phikmvvirus is a genus of viruses that infect bacteria. There are currently 16 species in this genus including the type species Pseudomonas virus phiKMV.[1][2]Bacteriophage phiKMV[3] and its relatives are known to be highly virulent phages, producing large (3–15 mm (0.12–0.59 in) diameter) clear plaques on a susceptible host.[4][5] The only reported exception is phage LKA1, which yields small plaques (1 mm (0.039 in)) surrounded by a halo. While all other P. aeruginosa-specific phikmvviruses use the Type IV pili as primary receptor, LKA1 particles attach to the bacterial lipopolysaccharide layer.
