[The demonstration of antibacteric power in a blood sample taken for blood culture. Preliminary note. (author's transl)].
To identify a possible "false" negative blood culture from a patient not declearing antibiotic treatment, we propose a "Residual Antibiotic Power" test (PAR-test) on the same blood sample to be rum in parallel with the blood culture. Hence we propose using B. stearothermophilus var. calidolactis, which we have found very sensitive to the common antibiotics used in Human Medicine. Suggested technique: agar+germ with an absorbent paper disc soaked with the sample, incubated for 3 hours at 60 degrees C, to give an easy test reading.
