Immunological responses to phospholipase-A of Salmonella typhi.
A 39 kD phospholipase-A was purified from Salmonella typhi. The enzyme was efficiently concentrated by precipitation with ammonium sulphate and purified by sequential use of column chromatography on DEAE-Sephacel and Sephadex G-100. Humoral and cellular immune responses were determined against both crude and purified phospholipase-A. Crude fraction was found to be more immunogenic than purified fraction.
