FIG. 1.

A. castellanii promotes the survival of V. parahaemolyticus. V. parahaemolyticus (V. para) POR1 (A) and E. coli K-12 (B) were cultured in the absence (open circles) or presence (open squares) of A. castellanii for 35 (A) and 31 (B) days. The number of bacteria was determined by plating serial dilutions on media selective for V. parahaemolyticus or E. coli as described in Materials and Methods. Results are reported as the number of bacteria recovered per ml; the limit of detection is 10 CFU. Data points represent the means ± standard deviations (SD) from triplicate cultures and are representative of at least three independent experiments.
