We assessed the antibody levels and risk factors for tetanus in an adult population in the Kocaeli Region of Turkey. In 595 individuals over 20 years of age, serum concentrations of anti-tetanus antibodies were detected by enzyme-linked immunosorbent assay and a brief questionnaire was administered. The overall immunity rate was approximately 80% and there was a progressive decline in protectio...

Background. Tetanus toxoid immunisation of pregnant mother has remained the most effective strategy in eliminating neonatal tetanus. Impaired production and/or transplacental transfer of antibodies may affect the effectiveness of this strategy. We studied the effect of maternal HIV infection on serum levels and transplacental transfer of anti-tetanus antibodies. Methods. A total of 162 mother-b...

background: hepatitis b virus (hbv) fails to produce appropriate immune responses in some healthy individuals; thus, different strategies have been adopted to promote immune responses. the current study aimed at evaluating the efficacy of hbv vaccine coadministered with tetanus-diphtheria (td) vaccine compared with hbv vaccine in healthy individuals through measuring hepatitis b surface antibod...

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 day 7 of gestation. Mice were reconsti...

Seroepidemiological studies of tetanus in Africans have focused mainly on adults especially pregnant women and data on children are scarcely reported. We investigated the seroprevalence of protective immunity level, determined risk factors for non-protection against tetanus, and evaluated the performance of Tetanos Quick Stick(®) (TQS) among hospitalized children aged 1-9 years in Nigeria. Bloo...

The secondary immune response to tetanus toxoid in 14 patients with rheumatoid arthritis (RA) has been studied in suspension cultures of peripheral blood lymphocytes (PBL) and synovial membrane obtained at synovectomy. Sequential cultures of PBL from three normal subjects established the optimal time of antibody response at 5 days. At this time, the antitetanus antibody produced was predominant...

OBJECTIVES To determine maternal and neonatal specific antibody levels to selected vaccine-preventable infections (pertussis, Haemophilus influenzae type b (Hib), tetanus and pneumococcus). DESIGN Prospective cohort study. SETTING A UK secondary care maternity unit (March 2011-January 2012). PARTICIPANTS Mothers and infants within 72 h of delivery were eligible. Unwell individuals, mother...

Antibody production in mice after immunization with diphtheria-pertussis-tetanus (DPT) vaccine was investigated. Six lots of the vaccine produced in the same year by six manufacturers in Japan were chosen. Production of IgE antibody specific to either diphtheria or tetanus toxoid varied among vaccine preparations used, although there was no apparent difference in IgG antibody production after i...

background: adjuvants are used to increase the immunogenicity of new generation vaccines, especially those based on recombinant proteins. despite immunostimulatory properties, the use of bacterial lipopolysaccharide (lps) as an adjuvant has been hampered due to its toxicity and pyrogenicity. brucella abortus lps is less toxic and has no pyrogenic properties compared to lps from other gram negat...

By integrating photopolymerized cross-linked polyacrylamide gels within a microfluidic device, we have developed a microanalytical platform for performing electrophoresis-based immunoassays. The microfluidic immunoassays are performed by gel electrophoretic separation and quantitation of bound and unbound antibody or antigen. To retain biological activity of proteins and maintain intact immune ...
