STRAIN Haemophilus parasuis SK-1 AS PATHOGEN OF SWINE HEMOPHILEOUS POLYSEROSITIS FOR PREPARING DIAGNOSTIC AND VACCINE PREPARATIONS Russian patent published in 2006 - IPC C12N1/20 A61K39/102 C12R1/21 

FIELD: veterinary microbiology, biotechnology.

SUBSTANCE: strain is deposited in the Collection of microorganism strains FGU VGNKI at the registration number Haemophilus parasuis SK-1-DEP. The strain is virulent in native state and possesses antigenic and immunogenic activity after inactivation. In culturing in broth PPLO-base liquid nutrient medium for 12 h the strain is accumulated with the titer value 9.3-9.7 lg CFU/cm³. The strain retains its own properties in storage in semi-liquid agar at 4-6°C for 1 month and in the lyophilized state at 4-6° for 1 year. The strain shows high biological, antigenic and immunogenic activities, it retains native immunobiological properties after inactivation that can be used in preparing highly effective diagnostic and vaccine preparations.

EFFECT: valuable properties of strain.
