Problems solved by technology

[0006] From the incidence rate of Pseudomonas infection, it can be found that it accounts for more than 30% of all clinical pathogenic bacterial infections in the past ten years. Although the antibiotics produced at home and abroad are changing rapidly, including cephalosporins, quinolones, and amino sugars, the present The morbidity and mortality of Pseudomonas maltophilia are still high, especially the mortality rate of Pseudomonas maltophilia is v

Abstract

The present invention provides a biological product capable of resisting stenotrophomonas maltophilia and Pseudomonas aeruginosa infection and raising the body fluid immunity and cell immunity of malignant tumor patient. The biological product is prepared with stenotrophomonas maltophilia, and may be prepared into various kinds of immunological preparations and immune regulating preparations. The medicine of the present invention has the special effect of preventing and treating stenotrophomonas maltophilia and Pseudomonas aeruginosa infection and treating ascites carcinoma and leukemia.

Description

1. [Technical field] [0001] Pseudomonas maltrophilia (Pseudomonas maltrophilia), also known as Stenotrophomonas maltophilia preparation (vaccine), and a manufacturing method thereof belong to the field of microbial engineering. Utilize this bacterium body or metabolite (polysaccharide) etc. to produce specific therapeutic or preventive medicine. Two, [background technology] [0002] Pseudomonas maltophilia preparation (vaccine) and its manufacturing method, this application did not find any similar project or technology through Internet search, as far as we know, the prior art closest to this application can be found in "China Biological Products Regulations" 2000 Edition , "Pseudomonas aeruginosa manufacturing and testing regulations" P262-266, and "Pseudomonas preparations manufacturing and testing regulations" P272-276. However, the preparations of Pseudomonas aeruginosa or Pseudomonas are only used for treating tumors, and are ineffective for the prevention and treatmen...
