On the phagocytosis in vitro of strains of Yersinia pseudotuberculosis after treatment with certain detergents and lipid solvents

Abstract

Reproduced from SciFinder with permission from the Chemical Abstracts Service. The addn. of Na lauryl sulfate [151-21-3] or petroleum ether to Y. pseudotuberculosis grown in a medium contg. 10% glycerol at 28° (conditions under which V and W antigens are not synthesized) significantly increased the phagocytosis of the bacterial cells by rabbit blood. The addn. of Na periodate or trypsin [9002-07-7] produced variable degrees of phagocytosis dependent on the virulence of the strains tested. The role of lipid synthesis in the restoration of phagocytosis at 28° is discussed.
