Inhibition of <i>S</i>. Typhimurium killing by anti-LPS antibodies from HIV-ve bactericidal, HIV+ve bactericidal and HIV+ve inhibitory sera.

<p>Log growth phase <i>S</i>. Typhimurium D23580 was added to a mixture of the purified anti-LPS antibodies (from HIV-ve bactericidal, HIV+ve bactericidal and HIV+ve inhibitory sera) and 50% HIV-uninfected human serum. The log₁₀ proportion of the starting number of bacteria remaining after 180 minutes was determined on LB agar. Each line represents inhibition of killing by anti-LPS antibodies from one serum. Data shown are from a single representative experiment, where each of the three independent experiments was performed in technical triplicates.
