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 o...

preparation of chitosan (cs) microspheres as a novel drug delivery vehicle for intranasal immunization using high, medium and low cs molecular weight (mw) was investigated in this study. diphtheria toxoid (dt) was used as a model antigen. the emulsion-solidification method was adopted for microencapsulation of dt.  in the first step, following the purification of semi-crude dt by the ion-exchan...

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 blo...

universal vaccination of neonates and children against diphtheria, tetanus and pertussis has had a tremendous impact on the control of these infectious diseases worldwide. immunization by the triple diphtheria, tetanus and whole cell pertussis vaccine (dtwp) has been applied in iran for almost 50 years. periodic assessment of immunogenicity of this vaccine is an important aspect of successful m...

Background and Objective: In Indonesia, diphtheria cases caused by Corynebacterium diphtheriae are still occurring until today. One of the causes is probably the diphtheria toxin repressor (dtxR) gene which influences toxin expression. Therefore, in this study the characterization of the gene was performed to determine the mutations that affect the DtxR protein.   Methods: The dtxR genes of ...

This article examines optimal control model for the spread of diphtheria disease. Diphtheria is an infectious disease caused by bacterium Corynebacterium diphtheriae. divided into six compartments, namely population susceptibles (

Background: Immunization against diphtheria, tetanus and pertussis has been applied in Iran since 1950. WHO suggests periodical evaluation of effectiveness of the triple diphtheria-tetanus-whole cell pertussis (DTwP) vaccine, worldwide. Objectives: To determine the immunogenicity of locally manufactured DTwP vaccine administered to preschool children in a number of health centers of Tehran in 2...

An unimmunized schoolchild with no history of foreign travel developed severe diphtheria. Epidemiological investigations led to the discovery a child in same class cutaneous diphtheria who had just returned from Bangladesh; this highlights importance swabbing all skin lesions acquired endemic areas during any outbreak investigation.

Relevance. It is known that antitoxic immunity saves from diphtheria, but does not prevent the carriage of Cd (tox+). Asymptomatic carriers (tox+) play a major role in maintaining epidemiological process diphtheria infection. Aims. Characteristics population composition and specifics kinetic reactions (tox-) simultaneously functioning among people. Results. The functional features specific indi...
