Killing Titer: Phage density (titer) determination in terms of the fraction of class="bap-term">bacteria killed.

Discussion

<p>The concept of killing titers, along with decimal reduction time, is useful toward understanding what phage densities are necessary to effect bacterial eradication during phage therapy. See Abedon (2011) for further discussion and references.

To my knowledge, the first publication describing killing titer determinations, however, is that of Luria and Dulbecco (1949); see Table 1 of that paper.
