“…Age and Candida.-The results in this trial agree with those of Stone and Mersheimer (1955-6), Childs (1956), and Smits et al (1966) in showing no association between age and isolation of Candida from faeces. They contrast, therefore, with the demonstration by Smits et al (1966) Candida and Symptoms.-In most trials of tetracycline and Mysteclin no valid measure of the association between symptoms and the presence of candida in the faeces has been possible, because either the candida isolations have been too few (Foltz et al, 1955-6;Hewitt et al, 1955-6;Younger et al, 1959), or the symptoms too few (Metzger et al, 1957), or both (Childs, 1956Tewari and Fletcher, 1966).…”
