A total of 84% of the levineae were infected by at least one of the phages, and 21 phage-host patterns were obtained. Only 9% of the C. freundii isolates were infected. One phage, DM-21, only infected L. malonatica whereas the other phages showed no species specificity. Most of the infectivity patterns were specific for either L. amalonatica or L. malonatica, but some patterns showed no host specificity. A correlation was found between dulcitol fermentation and infectivity with DM-21. There was no evidence of a relationship between infectivity and source of isolation. The recommendation that the proposed genus Levinea be accepted rather than the inclusion of these organisms within the genus Citrobacter is discussed.", }
