[An optimal blood culture technic].

For blood cultures in septicemic patients it is advisable to use two broth culture bottles. One bottle should be incubated with air, the other without (for anaerobes). Supplemented Peptone Broth II (Becton-Dickinson) and BHI Roche were superior for culturing aerobic and anaerob bacteria in comparison to other blood culture media. They are commercially available, and with these media it is not necessary to inoculate two bottles with blood from one patient. Supplemented Peptone Broth II is also suitable very well for the isolation of Campylobacter fetus and has a redoxpotential which is especially favourable for the isolation of anaerobes.
