Salmonella biofilm prevention and control is of great importance. This study, investigated the use of the isolated phage KM16 belonging to the family Myoviridae in the order Caudovirales. The phage genome size was 170,126 bp. Almost all phages were adsorbed to the host within 20 min. KM16 had a latent period of 70 min followed by a rise period of 40 min. Phage KM16 had the ability to lytically infect 10 out of the 12 clinical strains of S. paratyphi tested. Phylogenetic analysis indicated that the S. paratyphi 16S rRNA, crispr 1 and fimA genes correlated with the lytic spectrum of phage KM16. The lytic spectrum of phage KM16 correlated with Salmonella pili (fimA), and Salmonella pili were the recognition site for phage adsorption to the host. Phage KM16 (MOI = 0.1) had a better anti-biofilm effect than kanamycin sulfate (10 ug ml-1) in high-concentration Salmonella cultures.

D001435	Bacteriophages	Viruses whose hosts are bacterial cells.	Phages,Bacteriophage,Phage
D012336	RNA, Ribosomal, 16S	Constituent of 30S subunit prokaryotic ribosomes containing 1600 nucleotides and 21 proteins. 16S rRNA is involved in initiation of polypeptide synthesis.	16S Ribosomal RNA,16S rRNA,RNA, 16S Ribosomal,Ribosomal RNA, 16S,rRNA, 16S
D012475	Salmonella	A genus of gram-negative, facultatively anaerobic, rod-shaped bacteria that utilizes citrate as a sole carbon source. It is pathogenic for humans, causing enteric fevers, gastroenteritis, and bacteremia. Food poisoning is the most common clinical manifestation. Organisms within this genus are separated on the basis of antigenic characteristics, sugar fermentation patterns, and bacteriophage susceptibility.
D012482	Salmonella paratyphi A	A serotype of SALMONELLA ENTERICA that causes mild PARATYPHOID FEVER in humans.	Salmonella paratyphi,Salmonella enterica serovar Paratyphi A
D012483	Salmonella Phages	Viruses whose host is Salmonella. A frequently encountered Salmonella phage is BACTERIOPHAGE P22.	Salmonella Bacteriophages,Bacteriophage, Salmonella,Bacteriophages, Salmonella,Salmonella Bacteriophage,Salmonella Phage
D018441	Biofilms	Encrustations formed from microbes (bacteria, algae, fungi, plankton, or protozoa) embedded in an EXTRACELLULAR POLYMERIC SUBSTANCE MATRIX that is secreted by the microbes. They occur on body surfaces such as teeth (DENTAL DEPOSITS); inanimate objects, and bodies of water. Biofilms are prevented from forming by treating surfaces with DENTIFRICES; DISINFECTANTS; ANTI-INFECTIVE AGENTS; and anti-fouling agents.	Biofilm
