Fig 3. The effect of transferrin on A. pleuropneumoniae growth in CDM).

Fig 3

A. pleuropneumoniae was cultured in TSB medium overnight and then sub-cultured into CDM at an inoculation dose of 104 CFU/ml. Optical densities of bacterial cultures (OD600nm) were recorded at selected time points. Various concentrations of apo-transferrin (ATF) (A) or holo-transferrin (HTF) (B) were added into CDM. (C). ATF at 400μg/ml was added into CDM (ATF) and FeCl3 at different concentrations were supplemented into the medium containing ATF (ATF + Fe). A. pleuropneumoniae cultured in CDM without any supplementation was used as a control (CDM). Data are shown as means ± SD from four independent replications.
