Methods Peritoneal macrophages of guinea pigs were infected in vitro by three different Leptospira strains, the virulent Leptospira interrogans serovar Lai type strain Lai, the avirulent L. interrogans serovar Lai type strain IPAV, and the nonpathogenic L. biflexa serovar Patoc type strain PatocⅠ, respectively, and heat inactivated Staphylococcus epidermidis was added 0.5, 1.5, 3 and 6 h after infection and incubated for 30 min.

Membrane affinity quantified by IAM and liposome/buffer systems was a more efficient predicator of α values than hydrophobicity from n-octanol/buffer system. Consequently, not only hydrophobic force but also attractive polar extra-interactions involved in the binding to IAM and liposomal membranes but not in an n-octanol phase, ascribed to the binding process within AM. The binding to ordered lipid membrane in the larger part determined drugs'binding to AM intracellular compositions, and the ordered phospholipid plasma membrane was a potential site for drugs'binding in AM.
