[Antitoxin levels against tetanus in various age groups].

In this study, antitoxin levels against tetanus were examined in the sera of 261 male and 139 female subjects (totally 400 subjects) in the age range from one day to 85 years. Tetanus antitoxin titres were determined by Pitzurra et all. passive hemagglutination technique using turkey red blood cells. In the age group of 6-15 years, antitoxin levels were significantly higher than those of other groups and above 30 years old group this levels significantly below than the other groups (p less than 0.05). All groups of female, except the group under 5 years of age, had lower antitoxin levels than those male and this difference was found significant statistically (p less than 0.05).
