Lipopolysaccharide (LPS) structure impacts the bactericidal action of cationic peptides, such as polymyxin B (PMB), and sensitivity to killing by normal human serum (NHS). Cultivation of different subspecies strains of Yersinia pestis isolated from unrelated geographic origins at various temperatures (mammals, 37 degrees C; fleas, 25 degrees C; or winter hibernation, 6 degrees C) affects LPS composition and structure. We tested the susceptibilities of various strains of Y. pestis grown at these… CONTINUE READING
