Figure 7. Killing of K. pneumoniae by Neutrophils.

Casein-elicited peritoneal neutrophils were purified as described in the Methods. Cells and bacteria were mixed in a 1:1 ratio and incubated at 37°C for the indicated times when cell pellets were washed and supernatants pooled. Data in A is displayed as percent of input bacteria recovered ± standard deviation and represents an n= 3 repeated on separate days (total of n=6). A, wild type; B, TLR4^−/− mice. Pel; pellet, supe; supernatant. *, p<0.01.
