In the previous oceanographic survey on the distribution of TAKIKAWA'S so-called pathogenic halophilic bacteria, HORIE et al2). could not isolate the typical organisms, i. e. Group I, however, revealed that two groups of organisms, Group II and III, having similar features to Group I are widely distributed in the sea area. Group I organisms are suspected to cause acute gastro-enteritis. In order to detect the organisms from marine environments more excellent selective media are necessary. The present authors deviced a selective liquid medium, 3% NaCl containing arabinose ethyl violet broth (AE medium). Preparation of the AE medium is shown in Table 1. In the tentative method for the examination of pathogenic halophilic bacteria in the sea water according to the Ministry of Health and Welfare, BS medium is adopted as a selective liquid medium. The present survey was carried out mainly in the coastal areas around the Suruga Bay, the Izu Peninsula, the Sagami Bay and the Tokyo Bay, aboard the Umitaka-maru, a research vessel of the Tokyo University of Fisheries. In addition to surface sea-water, marine mud at the bottom and plankton were collected for the bacteriological examination. For one sample, a pair of selective liquid media, the AE medium and BS medium were used in order to compare each other. On the other hand, a selective agar medium, 4% NaCl sucrose mannitol bile salt agar, being shown in Table 2 was employed. Experimental results were shown in Fig. 1 and Table 4, 6 an...
