Killing of NTS by whole blood and serum from Malawian children.
In vitro killing of S. Typhimurium isolate D23580 (initial concentration 106 salmonellae/ml) at 180 minutes by (A) whole blood compared with serum and (B) whole blood with test aliquot lysed or unlysed prior to determination of viable salmonellae. Paired blood and serum are from 65 healthy Malawian children. Each point corresponds to blood and serum from 1 child. Lines of equivalence are shown.
