Oral vaccination offers the advantage of eliciting both a mucosal and a systemic immune response. This study investigated the use of polyacryl starch microparticles as adjuvant for oral vaccination against diphtheria. Diphtheria toxin or cross-reacting material (CRM197) were covalently conjugated to the microparticles and fed to mice by oral gavage. Investigation of formaldehyde treatment as a ...
Epidemics of diphtheria had occurred in China during eighteenth century. At that time, the western medicine introduced in China was very much limited and not popularized in clinical practice. The therapeutics for diseases including diphtheria was chiefly relied on Traditional Chinese Medicine. The ancient Chinese physicians had accumulated abundant clinical experiences written in medical classi...
Diphtheria is a contagious and life-threatening disease historically regarded as a major cause of mortality, particularly in children. Over the past centuries, frequent diphtheria outbreaks have occurred. Herein, after a quick look at the history of diphtheria throughout the world, a historical account of this lethal disease in Iran during the 19th and 20th centuries is presented.
In a population-based study in the Netherlands, diphtheria antitoxin antibodies were measured with a toxin-binding inhibition assay in 9, 134 sera from the general population and religious communities refusing vaccination. The Dutch immunization program appears to induce long-term protection against diphtheria. However, a substantial number of adults born before the program was introduced had n...
A polycentric study was carried out between 1993 and 1995 in order to evaluate diphtheria immunity on a representative sample of population from different areas of Italy. To determine diphtheria antitoxin, sera from 5187 apparently healthy subjects, divided according to sex and age groups, were titrated using an ELISA indirect method. A basic protective titre of diphtheria antitoxin (> 0.01 IU ...
Experiments were carried out to examine the adjuvanticity of polar glycopeptidolipids of Mycobacterium chelonae (pGPL-Mc) or the London rocket seed (LRS) when combined with diphtheria and tetanus toxoids in an oral immunization of the African green monkey. The results showed that none of the monkeys receiving diphtheria and tetanus toxoids combined with 25 mg/kg of pGPL-Mc showed an increase in...
BACKGROUND AND OBJECTIVES Tetanus and diphtheria are vaccine-preventable, infectious diseases with significant morbidity and mortality. Immunization by the diphtheria and tetanus toxoid (DT) has been applied in Iran for almost 50 years. However, there are very few data about the rate of immunity to these diseases in the adult population. the humoral immunity to tetanus and diphtheria among bloo...
We determined the diphtheria toxin phenotype of specially selected isolates of Corynebacterium ulcerans and Corynebacterium pseudotuberculosis (C. ovis). All produced proteins similar in size and immunological structure to diphtheria toxin. As with diphtheria toxin, they exhibited ADP-ribosylating activity, and their synthesis was regulated by iron.
Cutaneous diphtheria is endemic in tropical countries but unusual in the United Kingdom. Four cases occurred in the United Kingdom within 2 months in 2002. Because cutaneous diphtheria causes outbreaks of both cutaneous and pharyngeal forms, early diagnosis is essential for implementing control measures; high diphtheria vaccination coverage must also be maintained.
On 1 January 1996, diphtheria-tetanus revaccination at the age of 5 years was implemented in the Danish Childhood Vaccination Programme. Initially, a combined DT vaccine containing 25 Lf diphtheria toxoid was used. Due to a high frequency of spontaneously reported adverse reactions, however, concerns were raised that the diphtheria dose was too high, and it was reduced to 6.25 Lf. This survey p...
