The epidemiological investigation using purified tuberculin protein was carried out in Fukushima Prefecture in 1965 and 1966. The subjects of this investigation were 856 healthy pupils of junior middle school in Haramachi-City. The skin reaction of purified tuberculin protein prepared from several strains (Ishii--Scotochromogens, Gamou--Nonphotochromogens, P<SUB>16</SUB>--Photochromogens, Sato--Rapidd growers) of unclssif ied mycobacteria and human type mycobacteria (H<SUB>37</SUB>Rv) measured on the populations of normal healthy pupils. o.15γ of one purified tuberculin protein prepared from unclassified mycobacteria was used as antigen for intracutaneously on the flexion surface of forearm. The same amunt of purified tuberulin protein prepared from tubercle bacillus was injected on the other forearm as the control. For an injection site, the middle one-third part of the forearm was used avoiding the usual site of tuberculin reaction. The results obtained were as follows ; 1) The rate of positive reaction of Ishii was the highest among these four unclassified mycobacteria. 2) The mean value of the diameter of skin reaction by unclassified mycobacteria was almost same size with except rapid grower Sato. 3) Great changes of the coefficients of correlation were found between the human type mycobacteria and unclssified mycobacteria of different kinds.
