13. Immunoglobulin G (IgG) Subclass Distribution and IgG1 Avidity of Antibodies in Human Immunodeficiency Virus-Infected Individuals after Revaccination with Tetanus Toxoid
In human immunodeficiency virus (HIV)-infected individuals the amount of antibodies formed after vaccination with T-cell-dependent recall antigens such as tetanus toxoid is proportional to the peripheral blood CD4+ T-lymphocyte counts. To investigate whether the immunoglobulin G (IgG) subclass distribution and avidity of the antibodies produced after va

14. Comparison of Five Commercial Anti-Tetanus Toxoid Immunoglobulin G Enzyme-Linked Immunosorbent Assays▿
Five commercially available enzyme-linked immunosorbent assays for the measurement of anti-tetanus toxoid immunoglobulin G (IgG) antibodies were evaluated for performance. The data suggest that there are manufacturer-dependent differences in sensitivity and accuracy for the determination of tetanus toxoid IgG antibodies that could result in different diagnos

15. Influence of Mouse Strain on the Assayed Potency (Unitage) of Tetanus Toxoid
The assayed potency of an adsorbed tetanus toxoid C2, relative to the international standard for tetanus toxoid (adsorbed), varied significantly with the use of different strains of mice. The unitage was highest with NIH mice, and it was not significantly different from that with CFW mice. With CDF1 and BALB/c mice, however, the assayed potency was significa

16. Immunological evaluation of meningococcal group C polysaccharide-tetanus toxoid conjugate in mice.
Neisseria meningitidis group C polysaccharide-tetanus toxoid conjugate was prepared to obtain the polysaccharide component in a thymus-dependent form and to preserve the immunogenic properties of the tetanus toxoid component. Biochemical and immunochemical analyses of this conjugate revealed that (i) it was composed of equal amounts of polysaccharide and pro

17. Vaccine potential of Haemophilus pleuropneumoniae oligosaccharide-tetanus toxoid conjugates.
Oligosaccharides of smooth-type lipopolysaccharide (LPS) and oligosaccharides of rough-type LPS were isolated from Haemophilus pleuropneumoniae and conjugated to tetanus toxoid by reductive amination. The antigenic and immunogenic characteristics of the oligosaccharides, the oligosaccharide-tetanus toxoid conjugates, and the LPS of H. pleuropneumoniae were d

18. Preparation and immunochemical characterization of meningococcal group C polysaccharide-tetanus toxoid conjugates as a new generation of vaccines.
Neisseria meningitidis group C polysaccharide-tetanus toxoid conjugates have been prepared by using high-molecular-weight polysaccharide and purified tetanus toxoid and 1-ethyl-3-(3-dimethylaminopropyl)-carbodiimide as a coupling reagent. The influence of three conditions of preparation was studied. Biochemical assays, the enzyme-linked immunosorbent assay,

19. Simultaneous administration of diphtheria-tetanus-pertussis-polio and hepatitis B vaccines in a simplified immunization program: immune response to diphtheria toxoid, tetanus toxoid, pertussis, and hepatitis B surface antigen.
We studied the interactions of hepatitis B vaccine with other vaccines used in the World Health Organization expanded programs of immunization. Three groups of Senegalese children were vaccinated with hepatitis B vaccine (HB) alone, diphtheria-tetanus-pertussis (DTP)-polio vaccine alone, or a combination of hepatitis B vaccine and DTP-polio vaccines simultan

20. Impaired human responses to tetanus toxoid in vitamin A-deficient SCID mice reconstituted with human peripheral blood lymphocytes.
Vitamin A deficiency is associated with increased childhood morbidity and mortality from respiratory and diarrheal diseases. In order to evaluate the effect of vitamin A on human antibody responses, we developed a vitamin A-deficient severe combined immunodeficient (SCID) mouse model. Vitamin A-deficient mice were produced by depriving them of vitamin A at d

21. Neonatal mouse protection against infection with multiple group B streptococcal (GBS) serotypes by maternal immunization with a tetravalent GBS polysaccharide-tetanus toxoid conjugate vaccine.
Most cases of neonatal sepsis and meningitis caused by group B streptococci (GBS) are attributable to one of four major capsular serotypes: Ia, Ib, II, or III. Because resistance to infection with GBS has been correlated with the presence of serum antibodies to the type-specific capsular polysaccharides in both experimental animals and human neonates, effort

22. Detection of antibodies to tetanus toxoid: comparison of a direct haemagglutination method with a radioimmunoassay.
Two methods of detecting antibodies to tetanus toxoid were compared, a radioimmunoassay (RIA) employing radiolabelled staphylococcal protein A and a direct haemagglutination (HA) method employing sheep erythrocytes coupled to tetanus toxoid with chromic chloride. These were shown to have a similarly high specificity with the HA method showing slightly higher

23. Comparison of Enzyme-Linked Immunosorbent Assay and Passive Hemagglutination Method for Quantification of Antibodies to Lipopolysaccharide and Tetanus Toxoid in Rats
In a comparative study, the enzyme-linked immunosorbent assay, using peroxidase labeled anti-rat immunoglobulin M and immunoglobulin G, and the passive hemagglutination test were applied to determine the primary and secondary antibody response to lipopolysaccharide and tetanus toxoid in rats. In the enzyme-linked immunosorbent assay, the antigens were bound

24. Antibody Response to Successive Booster Doses of Tetanus Toxoid in Adults
A study of the rise and fall in circulating tetanus antitoxin in a group of 15 adults after basic and booster immunization indicates that although individuals vary greatly in their responsiveness to toxoid, the falloff in antitoxin appears to be fractionally constant for each individual, and over periods of 5 to 6 years appears to be the same after successiv
