Tetanus antitoxin titration by haemagglutination

Human tetanus antitoxin.

Tetanus Antitoxin from Intraocular Transplants **

Evidence for antibody formation by various cells, tissues, and organs has come mainly from studies employing the following methods: (i) extracts of tissue cultures,'l (ii) cannulization of afferent and efferent lymph,"'X (iii) extracts of cells, tissues, and organs,"' (iv) extirpation of the spleen," and (v) roentgen-radiation of animals with lead-protected mobilized spleens.' Although the repo...

The Destruction of Tetanus Antitoxin by Chemical Agents.

It is only to be regretted that this step was not taken earlier, for the large number of idle bulls now in the herd is both a detriment to that body and a positive loss of once good skins. This menace in the growth of the herd has been repeatedly pointed out (Clark, 1914, 1916, 1917; Osgood, Preble, and Parker, 1915) to those having the matter in charge. The last column in table 1 contains the ...

Tetanus antitoxin titres in military personnel.

A study was made of the titres of tetanus antitoxin in the sera of 186 recruits and 886 serving personnel. All were found to have titres of more than 0.01 IU per ml, the titre regarded as sufficient to provide protection from tetanus. The percentage of recruits with tetanus antitoxin titres less than 0.1 IU per ml was significantly greater than the percentage of serving personnel with antitoxin...

Neonatal tetanus despite protective serum antitoxin concentration.

Using the ELISA technique to estimate serum antibodies against tetanus toxin, seven neonates with clinical tetanus were found to have antibody levels 4-13 times higher than the presumed minimum protective level of 0.01 IU/ml. All but one of their mothers had been vaccinated with tetanus toxoid in pregnancy. In two other neonates, whose mothers had received multiple booster doses of toxoid durin...
