ANTIBACTERIAL COMPOSITION FOR PREVENTION OR TREATMENT OF HOSPITAL INFECTIONS (VERSIONS), BACTERIOPHAGE STAMPS USED TO OBTAIN SUCH COMPOSITION Russian patent published in 2017 - IPC A61K39/02 

FIELD: biotechnology.

SUBSTANCE: composition includes 7 strains of bacteriophage, each represented by a combination of bacterial phagolysates filtrates with lytic activity of at least 10^-4 according to Appelman concerning test strains and isolated bacterial isolates, as well as target additives in an amount of 0.01±99.99 wt % of composition weight. At that, Staphylococcus aureus phagolysate filtrate obtained using the Staphylococcus aureus SCH1 bacteriophage strain, deposited in the collection of FBIS SSC PVB of Rospotrebnadzor under number Ph-105, Staphylococcus aureus phagolysate filtrate obtained using the Staphylococcus aureus SCH111 bacteriophage strain, deposited in the collection of FBIS SSC PVB of Rospotrebnadzor under number Ph-95, Klebsiella pneumoniae phagolysate filtrate, obtained using the Klebsiella pneumoniae KPV15 bacteriophage strain, deposited in the collection of FBIS SSC PVB of Rospotrebnadzor under number Ph-90, Klebsiella pneumoniae phagolysate filtrate, obtained using the Klebsiella pneumoniae KPV811 bacteriophage strain, deposited in the collection of FBIS SSC PVB of Rospotrebnadzor under number Ph-91, Pseudomonas aeruginosa phagolysate filtrate, obtained using the PA5 Pseudomonas aeruginosa bacteriophage strain, deposited in the collection of FBIS SSC PVB of Rospotrebnadzor under number Ph-88, Pseudomonas aeruginosa phagolysate filtrate, obtained using the Pseudomonas aeruginosa PA10 bacteriophage strain, deposited in the collection of FBIS SSC PVB of Rospotrebnadzor under number Ph-89, Acinetobacter baumannii, phagolysate filtrate, obtained using the Acinetobacter Baumannii AM24 bacteriophage strain, deposited in the collection of FBIS SSC PVB of Rospotrebnadzor under number Ph-106. The composition version also contains Acinetobacter baumannii phagolysate filtrate, obtained using the Acinetobacter baumannii AP22 bacteriophage strain, deposited in the collection of FBIS SSC PVB of Rospotrebnadzor under number Ph-42. The appropriate bacteriophage strains are also proposed. Nucleic acid molecules corresponding to the genome of the said bacteriophages are also proposed.

EFFECT: expanded range of products containing highly selective natural antibacterial components as the main active ingredient, ensured biological stability and activity of bacteriophages in the agent composition, the composition has a low risk of toxic and side effects, allows to expand versions and methods of practical application of the agent containing bacteriophages, provides storage stability and application efficiency over a wide temperature range.
