Effect of Bacteria and Their Products on Migration of Leukocytes.

Abstract
[long dash]The bacterial endotoxins of Salmonella typhosa, Pseudomonas aeruginosa and Serratia marcescens inhibited the migration of human leukocytes. The same effect was noted with filtrates of Neisseria intracellularis and whole bacteria of S. typhosa and P. aeruginosa. No inhibition was noted with Micrococcus aureus, Diploccus pneumonia or the polysaccharide of Type III.
