Abstract: | Antiphage sera were produced in rabbits against the HM-phages of Clostridium saccharoperbutylacetonicum; on the basis of cross-neutralization experiments with homologous and heterologous antisera, the twelve HM-phages were classified into three serological groups, termed I, II and III. Group I contained seven phages, i.e., HM 1, HM 2, HM 8, HM 9, HM 10, HM 11 and HM 12. Group II contained four phages, i.e., HM 3, HM 4, HM 5 and HM 6, and group III one phage, i.e., HM 7. This classification was in accord with morphological one that was reported in the preceding paper. By using the K value of antisera, the degree of serological relatedness among the phages within groups I and II was demonstrated. On the bases of serological similarities and of dissimilarities in host-rang specificity, the phages of groups I and II are considered as host range mutants derived from an identical ancestor, HM 1 and HM 3, respectively. |
