Evaluation of Potency on Diphtheria and Tetanus Toxoid for Adult Vaccines by In Vivo Toxin Neutralization Assay Using National Reference Standards [PDF]

open access: yesOsong Public Health and Research Perspectives, 2018
Objectives Vaccinations against diphtheria and tetanus are essential in providing immunity against these bacterial infections. The potency of diphtheria and tetanus toxoid vaccines can be measured using the in vivo toxin neutralization assay.

SINGLE CHAIN VARIABLE FRAGMENTS OF ANTIBODIES AGAINST DIPHTHERIA TOXIN B-SUBUNIT ISOLATED FROM PHAGE DISPLAY HUMAN ANTIBODY LIBRARY [PDF]

open access: yesBiotechnologia Acta, 2014
Diphtheria toxin is an exoantigen of Corynebacterium diphtheriae that inhibits protein synthesis and kills sensitive cells. The aim of this study was to obtain human recombinant single-chain variable fragment (scFv) antibodies against receptor-binding B ...

Diphtheria: A case series from West Maharashtra, India

open access: yesJournal of Medical Sciences and Health, 2022
Diphtheria is an acute infectious toxin mediated disease caused by Corynebacterium diphtheriae. Effective vaccination has decreased the incidence of disease globally. However, despite of a full-fledged Universal Immunization Programme, the cases

The entry of diphtheria toxin into the mammalian cell cytoplasm: evidence for lysosomal involvement [PDF]

open access: yes, 1980
Lysosomotropic amines, such as ammonium chloride, are known to protect cells from the cytotoxic effects of diphtheria toxin. These drugs are believed to inhibit the transport of the toxin from a receptor at the cell exterior into the cytoplasm where a ...

Coexistence of Competing Microbial Strains under Twofold Environmental Variability and Demographic Fluctuations [PDF]

open access: yesNew J. Phys 25, 123010 (2023), 2023
Microbial populations generally evolve in volatile environments, under conditions fluctuating between harsh and mild, e.g. as the result of sudden changes in toxin concentration or nutrient abundance. Environmental variability thus shapes the long-time population dynamics, notably by influencing the ability of different strains of microorganisms to ...

Diphtheritic myocarditis: A case series and review of literature

open access: yesJournal of Family Medicine and Primary Care, 2020
Myocarditis in patients with diphtheria is a toxin-mediated complication that sets in after one week of onset of respiratory illness. Early administration of antidiphtheritic serum in patients with clinical diphtheria before the onset of myocarditis is ...

Proteomics of diphtheria toxoid vaccines reveals multiple proteins that are immunogenic and may contribute to protection of humans against Corynebacterium diphtheriae [PDF]

open access: yes, 2019
Introduced for mass immunization in the 1920s, vaccines against diphtheria are among the oldest and safest vaccines known. The basic principle of their production is the inactivation of purified diphtheria toxin by formaldehyde cross-linking, which ...
