Killing of six strains of <i>Salmonella</i> by anti-LPS IgG from HIV+ve bactericidal sera.

<p>A) <i>S</i>. Typhimurium D23580, (B) <i>S</i>. Typhimurium LT2, (C) <i>S</i>. Enteritidis D24954, (D) <i>S</i>. Senftenberg 20050439, (E) <i>S</i>. Enteritidis SL7488, (F) <i>S</i>. Agona 20071186. Log growth phase <i>Salmonella</i> was added to a mixture of the purified antibodies and 75% BRS as complement source. The log₁₀ proportion of the starting number of bacteria remaining after 180 minutes was determined on LB agar. (G) Flow cytometric determination of anti-LPS IgG, from HIV+ve bactericidal sera, to the <i>Salmonella</i> strains. Each line/point represents one serum (n = 4).
