Problems solved by technology

Virus vaccines are recombinant subunit vaccines or attenuated virus vaccines for human infection. Due to long-term infection of the human body, people often develop tolerance to their antigens and do not recognize them, or the recognized antigenic determinants are limited, so the immune effect is not good, and the preventive effect not ideal, almost ineffective

Abstract

The invention discloses a method for preparing a composite IgY antibody against cold virus, Streptococcus pneumoniae and Staphylococcus. Incomplete adjuvant immunogen, immunize laying hens subcutaneously and intramuscularly, extract IgY antibody from immunized hen egg yolk by water dilution method, apply two-step ammonium sulfate salting-out method to purify IgY antibody, and obtain anti-cold virus and Streptococcus pneumoniae, Staphylococcus complex IgY antibody. The product prepared by using the specific anti-influenza virus, Streptococcus pneumoniae, and staphylococcus compound IgY antibody of the present invention can be used to prevent and treat upper respiratory tract infection caused by influenza virus, Streptococcus pneumoniae, staphylococcus, and viruses and bacteria with common antigens. Infectious inflammation, such as cold, rhinitis, sinusitis, tonsillitis, pharyngitis, bronchitis, etc.

Description

technical field [0001] The invention relates to a preparation method and application of compound IgY antibody against cold virus, streptococcus pneumoniae and staphylococcus. Background technique [0002] The onset of upper respiratory tract viral infection and secondary bacterial infection has no time or seasonal characteristics, and occurs all year round, and the incidence group is not selective, everyone can develop the disease, and it can occur repeatedly. A cold is an infection of the upper respiratory tract. Colds can usually be caused by seasonal influenza viruses and non-seasonal rhinoviruses, coronaviruses, respiratory syncytial virus, and adenoviruses. Secondary infection of the upper respiratory tract or external Streptococcus pneumoniae and Staphylococcus lead to inflammation of the upper respiratory tract. There is currently no effective drug available for viral infection, and premature use of antibiotic prophylaxis is not allowed, and may even lead to the emer...
