Figure 1

Acanthamoeba castellanii exhibited reduced association with Enterobacter aerogenes compared with Aeromonas hydrophila . Association assays were performed to determine bacterial association with A. castellanii as described in “Methods”. (A) represents ratio of bacteria per amoeba, while (B) represents bacteria associated with amoeba (% of the original inoculum). Results are represented as the mean ± standard error of three independent experiments performed in duplicate.
