• The author separated 120 strains of Proteus group from the stools of 1,150 acute gastroenteritis patients and normal men, and classified them according to the Bergey's manual after investigating their morphological and biochemical properties. At the same time, an investigation on the rate of their occurrence as divided by season as well as a comparative study of their distribution in the intestine or acute gastroenteritis patients with that in the intestine of normal men was conducted. The results of the investigation are summarized as follows: 1) 120 strains of the Proteus group were found in the stools of 1,150 persons under investigation and their occurrence rate was 10.4%. 2) Morphological and biochemical properties of the Proteus group found in the stools were in accord with the descriptions by Bergey et al., with the exception of 7 strains which seemed to be of different type. 3) The 120 strains of Proteus group were identified, according to Bergey's classification, as follows: 33 strains of P. vulgar is (27.5%), 67 strains of P. mirabilis (55.8%), 13 strains of P. rettgeri (10.8%) and 7 strains of Atypical species (5.8%). Not a single strain conformable to P. morganii was found. 4) Winter showed the lowest level (4.7%) in the rate of occurrence of the Proteus in the intestine and summer showed the highest level (18.8%), with spring and autumn showing the intermediary values of 7.5% and 13%, respectively. Of the 10 normal men examined for four seasons, only 2 produced one strain each of the Proteus in summer. No species of bacteria belonging to the Proteus group were found in other 8 men in any season. 5) An investigation showed that the rate of occurrence of the Proteus group in the patients suffering from acute gastroenteritis was slightly higher that in normal men, as evidenced by the following percentages: dysentery patients, 13.3%, acute enteritis patients, 15%, dyspepsia patients 17.5% and normal men 9.3%.
