Catecholamine induced <i>A</i>. <i>pleuropneumoniae</i> growth in CDM containing ATF.

<p><i>A</i>. <i>pleuropneumoniae</i> was cultured in TSB medium overnight and then sub-cultured into CDM using an inoculation dose of 10⁴ CFU/ml. ATF at 400μg/ml was added into CDM (ATF). Epi, NE and DA at 50μM were supplemented into the medium containing ATF (ATF + Epi/NE/DA). <i>A</i>. <i>pleuropneumoniae</i> cultured in CDM without any supplementation was used as a control (CDM). <b>(A)</b>. Optical densities of bacterial cultures (OD_600nm) were recorded at selected time points. <b>(B)</b>. Bacterial viable numbers were recorded at 6 h, 8h and 10h. Data are shown as means ± SD from four independent replications.
