Infection trials (see Table 1) showed that Daphnia magna clone Kela-39-09 is susceptible to Pasteuria ramosa clone C1 but resistant to C19. Kela-18-10 is resistant to C1, but susceptible to C19. LF = low food condition; HF = high food condition; single = Daphnia raised single in a 100 mL jar; crowded = Daphnia randomly picked from crowded cultures (high density). The bold characters highlights results where P. ramosa were attached to the D. magna oesophagus
