Heterotrophic growth from well and drinking water and ATD microorganisms in BVFH. Heterotrophic plate count analysis was performed on ATD (a-b), well water (c-d), and drinking water (e-f) control wells without F. tularensis after incubation in BVFH medium. Heart infusion agar plates shown here illustrate growth of background organisms after 0 (a, c, and e) and 48 h (b, d, and f) of incubation at the indicated dilutions. Images are representative of three replicates
