These years, not a few studies have been reported on mycobacteriophage from the standpoint of phage typing (Penso et al., 1949; Hnatoko, 1953; Froman et al., 1954, 1959; Takeya et al., 1957, 1959; Doke, 1960; Hikawa, 1959; Segawa et al., 1960; Redmond et al., 1960; Murohashi et al., 1959, 1961) . Almost all of the phages studied were isolated from soil samples, and the studies were carried out independently by researchers of different laboratories according to their own methods. Differences in the biological properties between these phages were not yet sufficiently analysed in comparison. To identify or classify Mycobacteria by the use of phages isolated in various parts of the world, it seems methodologically indispensable to select adequate phage strains by their biological properties.
In the present paper, results of serological studies on the classification of 32 mycophage strains are presented. Among these phages 19 strains were sent by the courtesy of G. Penso, S. Froman, P. Hauduroy, K. Takeya and S. Doke and the remaining 13 were isolated by the present authors (Murohashi et al., 1961) . Further, based on the results obtained, phages were selected temporarily which seemed to be suitable for the typing of Mycobacteria in the present stage of the mycophage studies.
