摘要:
A composition comprising intact killed bacterial cells that contain a therapeutic nucleic acid, a drug or a functional nucleic acid is useful for targeted delivery to mammalian cells. The targeted delivery optionally employs bispecific ligands, comprising a first arm that carries specificity for a killed bacterial cell surface structure and a second arm that carries specificity for a mammalian cell surface receptor, to target killed bacterial cells to specific mammalian cells and to cause endocytosis of the killed bacterial cells by the mammalian cells. Alternatively, the delivery method exploits the natural ability of phagocytic mammalian cells to engulf killed bacterial cells without the use of bispecific ligands.

The presently-disclosed subject matter relates to antibodies, compositions, and methods for inhibiting and treating pathogen infection and providing contraception. In particular, the presently-disclosed subject matter relates to inhibiting and treating pathogen infection and providing contraception in a subject using compositions and antibodies capable of trapping pathogens or sperm in mucus, thereby inhibiting transport of pathogens or sperm across mucus secretions. The subject matter further relates to methods for monitoring the effectiveness of vaccines by detecting antibodies capable of trapping pathogens in mucus.

The invention relates to the use of an agent selected from the group consisting of antibodies, antibody portions, insulin-like growth factor antagonists, toll-like receptor antagonists, and mixtures thereof for the treatment or the prophylaxis of certain diseases.
摘要:
Intact bacterially derived minicells containing functional nucleic acids or plasmids encoding functional nucleic acids can reduce, in targeted mammalian cells, drug resistance, apoptosis resistance, and neoplasticity, respectively. Methodology that employs minicells to deliver functional nucleic acids, targeting the transcripts of proteins that contribute to drug resistance or apoptosis resistance, inter alia, can be combined with chemotherapy to increase the effectiveness of the chemotherapy.

摘要:
Nucleic sequences from the genome of Salmonella Typhi include all or part of the genetic information required for the in vitro infection of cultured HeLa cells by Salmonella bacteria. Polypeptides encoded by these nucleic sequences are also described, as is the use of said polypeptides and nucleic sequences for implementing methods of in vitro Salmonella detection in biological samples which are thought to contain it.

摘要:
A combination vaccine, with methods of preparation and treatment, for protection against Gram negative bacterial diseases. The vaccine includes a killed suspension of a bacterial mutant from the taxonomic family Enterobacteriaceae, a B-lymphocyte proliferating immune modulator, and a protein and lipid binding adjuvant. A hyperimmune serum for treating diseased animals is prepared by vaccinating a donor animal with the combination vaccine and then preparing clot serum containing antigen specific antibodies. The mutant is ATCC No. 53000 and is produced by ionizing radiation of Salmonella enteritidis. The immune modulator is a detoxified extract of lipopolysaccharide and is useful with many antigens to enhance primary immune response.
