The present invention provides a method for reducing the risk of bacterial infection or sepsis in a susceptible patient by treating the susceptible patient with a pharmaceutical composition containing bacteriophage of one or more strains which produce lytic infections in pathogenic bacteria. Preferably, treatment of the patient reduces the level of colonization with pathogenic bacteria susceptible to the bacteriophage by at least one log. In a typical embodiment, the susceptible patient is an immunocompromised patient selected from the group consisting of leukemia patients, lymphoma patients, carcinoma patients, sarcoma patients, allogeneic transplant patients, congenital or acquired immunodeficiency patients, cystic fibrosis patients, and AIDS patients. In a preferred mode, the patients treated by this method are colonized with the pathogenic bacteria subject to infection by said bacteriophage.

An intracellular bacterial infection in a plant or animal is treated by administration to a plant cell or animal cell of a particle to which an infectious bacteriophage is covalently attached, wherein the particle is internalized by the cell. Particles with phage attached and compositions comprising the particles are provided. A formulation, for treatment of a bacterial infection, comprises bacteriophage, liquid carrier and adhesive, which dries so that the adhesive adheres the bacteriophage to a surface, one such formulation comprising liquid carrier: 85%-99.98% by weight; bacteriophage: 0.01%-5% by weight; and adhesive: 0.01%-10% by weight.

The invention relates to a mouse hybridoma cell strain secreting a clostridium tetani bacillus exotoxin monoclonal antibody, wherein the strain has a preservation number of CCTCC (China Center for Type Culture Collection) NO. C201257. The invention further relates to a clostridium tetani bacillus exotoxin monoclonal antibody prepared by the mouse hybridoma cell strain; the invention further provides an Fab antibody, comprising a kappa chain and an Fd chain; the kappa chain and the Fd chain are obtained by amplifying from total RNA (ribonucleic acid) of the hybridoma cell strain. The invention further relates to a medicine for preventing or treating clostridium tetani bacillus infection, comprising the clostridium tetani bacillus exotoxin monoclonal antibody and / or the Fab antibody, and a pharmaceutically acceptable carrier. According to the invention, a monoclonal antibody for effectively neutralizing tetanus exotoxin is screened with natural tetanus exotoxin, and an Fab gene engineering antibody which is produced by large scale in vitro and which has toxin neutralizing effect is prepared with a gene engineering antibody technology on the basis of the monoclonal antibody.

The present invention discloses a polypeptide with tubercle bacillus immunogenicity, which contains a sequence shown by Seq ID No.2 in the sequence table. The present invention also discloses a kit containing the polypetide as above. When the polypeptide and the kit are adopted to detect the infectivity of tubercle bacillus, the false positive rate is greatly decreased, while the true positive rate can be kept unchanged.
