Toxin-neutralizing effect of antibody against subtilisin-digested tetanus toxin.
A form of systemic tetanus with atypical symptoms was observed in mice injected in the left thigh with a mixture of tetanus toxin and antibody produced in guinea pigs against a fragment of toxin obtained from a subtilisin digest of the crystallized toxin. The mice did not show typical symptoms of the local tetanus such as convulsions or spastic paralysis of the injected limb.
متن کاملCell surface-exposed tetanus toxin fragment C produced by recombinant Bacillus anthracis protects against tetanus toxin.
Bacillus anthracis, the causal agent of anthrax, synthesizes two surface layer (S-layer) proteins, EA1 and Sap, which account for 5 to 10% of total protein and are expressed in vivo. A recombinant B. anthracis strain was constructed by integrating into the chromosome a translational fusion harboring the DNA fragments encoding the cell wall-targeting domain of the S-layer protein EA1 and tetanus...
متن کاملProtective human hybridoma antibody to tetanus toxin.
Postimmunization human B lymphocytes and mouse myeloma cells were fused to produce interspecies hybridomas secreting human antibody of predefined specificity with an initial frequency comparable to intraspecies fusion. After 13 mo in culture, one clone continued to secrete high titers of human IgG antitetanus toxin antibody. This antibody binds to the B fragment of tetanus toxin and protects mi...
متن کاملCloning and expression of tetanus toxin C fragment (Fc) in prokaryotic vector for constructing recombinant protein based vaccine for tetanus
Tetanus is a disease caused by tetanus toxin, a potent inhibitor for the release of inhibitory neurotransmitter in the central nervous system that causes spastic paralysis. Fragment C (52 kD) of this toxin is responsible for binding to the neuronal membrane. For this reason, and also its non toxigenic and immunogenic nature, this fragment might be ideal for new vaccine development. Presently, w...
متن کاملSevere tetanus--in spite of tetanus toxoid.
A 66-year-old man sustained an injury to his right foot while gardening. Despite receiving tetanus toxoid one hour later and adequate wound toilet, he developed severe tetanus complicated with autonomic dysfunction six days later. He died 20 days after admission. This case shows that tetanus toxoid alone may not be sufficient to prevent tetanus in wounded patients. Careful consideration must be...
