The identification of diphtheria, tetanus and pertussis vaccines by single radial and double immunodiffusion techniques. 1985

R Winsnes, and B Møgster

The identification tests for adsorbed diphtheria, tetanus and pertussis vaccines, which are required by the European Pharmacopoeia to be undertaken in animals, may be replaced by precipitation tests, for instance in agaros gels. Such in vitro tests eliminate the use of animals and are less expensive and time-consuming. The single radial immunodiffusion technique is a suitable semiquantitative test, while the double diffusion test is necessary for the investigation of complete or partial identity. The precipitates obtained in the single radial diffusion tests and in double diffusion tests with diphtheria toxoid were visible without staining; those obtained in the double diffusion tests with tetanus toxoid were weaker and staining was sometimes needed.

UI	MeSH Term	Description	Entries
D010567	Pertussis Vaccine	A suspension of killed Bordetella pertussis organisms, used for immunization against pertussis (WHOOPING COUGH). It is generally used in a mixture with diphtheria and tetanus toxoids (DTP). There is an acellular pertussis vaccine prepared from the purified antigenic components of Bordetella pertussis, which causes fewer adverse reactions than whole-cell vaccine and, like the whole-cell vaccine, is generally used in a mixture with diphtheria and tetanus toxoids. (From Dorland, 28th ed)	Vaccine, Pertussis
D004168	Diphtheria Toxoid	The formaldehyde-inactivated toxin of Corynebacterium diphtheriae. It is generally used in mixtures with TETANUS TOXOID and PERTUSSIS VACCINE; (DTP); or with tetanus toxoid alone (DT for pediatric use and Td, which contains 5- to 10-fold less diphtheria toxoid, for other use). Diphtheria toxoid is used for the prevention of diphtheria; DIPHTHERIA ANTITOXIN is for treatment.	Diphtheria Vaccine,Toxoid, Diphtheria,Vaccine, Diphtheria
