diagnosis of hepatitis b is routinely based on of serological assay of hepatitis b surface antigen (hbsag). occult hepatitis b virus (hbv) infection is generally defined as the detection of hbv -dna in the serum or tissues of subjects who have negative test for hbsag. transmission of hbv infection has been documented from hbsag negative, anti-hbc positive blood and organ donors. the aim of this...

BACKGROUND In view of waning antitoxin titres over time after the last vaccine dose against diphtheria and tetanus, we determined the immunity levels in adults to identify most susceptible groups for protection in Singapore. METHODS Our study involved residual sera from 3293 adults aged 18-79 who had participated in a national health survey in 2010. IgG antibody levels were determined using c...

BACKGROUND/AIM To assess the immune status against tetanus in relation to self-declared vaccination status among an adult population in Yozgat, Turkey. METHODS Questionnaires and blood specimens were collected from 267 individuals over 18 years of age in Yozgat, Turkey. Antitetanus antibodies were determined quantitatively by enzyme-linked immunosorbent assay. RESULTS Among the 267 subjects...

An increase in Haemophilus influenzae type b (Hib) in British children has been linked to the widespread use of a diphtheria/tetanus/acellular pertussis combination vaccine (DTaP-Hib). We measured anti-polyribosyl-ribitol phosphate antibody concentration and avidity before and after a Hib booster in 176 children 2-4 years of age who had received 3 doses of DTP-Hib (either DT whole cell pertussi...

OBJECTIVES Tetanus is a vaccine-preventable infectious disease. It is caused by the bacterium Clostridium tetani. The aim of this study was to investigate tetanus immunity among adult trauma patients. MATERIAL AND METHODS This study was performed with 267 trauma patients who were admitted to the emergency department of Tepecik Training and Research Hospital in Izmir City, Turkey over a six mo...

Background and Objectives: HIV infected patients are at risk for vaccine-preventable infections such as tetanus and diphtheria (Td). In these patients, these antibodies tend to decline faster. Due to the limited data, this study assessed the seroprevalence of tetanus and diphtheria antibodies in HIV infected patients in Tehran, Iran. Materials and Methods: This case-control study was carried ou...

Background and Aims: Despite the fact that neonatal tetanus has been eradicated all over the world, it is still a significant health problem in some developing countries. The disease can even result in death. This is a worrying problem but it can easily be prevented by vaccination of the mothers. Vaccinating every pregnant woman with, at least, one dose of tetanus toxoid would be an affordable ...

Using a monoclonal antibody (A2B5), which binds to GQ ganglioside, and tetanus toxin, which binds to GD and GT gangliosides, distinct regions of human and rodent thymic epithelial cells have been identified. The lymphoid elements of the thymus do not bind A2B5 or tetanus toxin. The A2B5 and tetanus toxin-binding cells form a network of thymic epithelial cells throughout the thymic subcapsular c...

1. The proportions of lymphocyte subpopulations (by rosette tests) and the serum antibody levels (using haemagglutination techniques) were estimated in malnourished and well fed Nigerian children before and up to 21 d after immunization with tetanus toxoid or measles virus vaccine. 2. Significantly diminished (P less than 0.01) mean percentage T lymphocyte levels and considerably higher mean pe...

The effect of rabbit antiidiotypic antibody raised against human IgG F(ab')2 anti-tetanus toxoid (TT) antibodies on the in vitro synthesis of TT-specific IgE antibody by peripheral blood lymphocytes (PBL) was examined in three subjects. Two of these subjects were allergic twins whose sera persistently contained IgE anti-TT antibodies. The third subject was a nonallergic individual who had a sli...
