The hallmark of immunity to meningococcal disease is a bactericidal titer in serum of > or =1:4 measured with human complement, but this threshold titer may underestimate the extent of protection. We used the infant rat model of meningococcal bacteremia to measure group C passive protective activity in serum samples from 91 unimmunized adults living in California. A total of 35 sera (38.5%) had...
Azlocillin was relatively ineffective against actively growing cultures of Pseudomonas aeruginosa in tests of bacteriolytic and bactericidal activity in which ticarcillin demonstrated pronounced bactericidal effects over a wide range of concentrations. Microscopic observation showed that azlocillin generally induced the formation of filamentous cells of P. aeruginosa which lysed only slowly, bu...
Kill-kinetic methods were used to provide data on the bactericidal activity of subinhibitory (0.5x MIC), inhibitory (1x MIC), and suprainhibitory (4x MIC) concentrations of LY146032 against methicillin-susceptible and -resistant Staphylococcus aureus and Staphylococcus epidermidis. These bactericidal activities were compared with those of methicillin, cefazolin, cefamandole, cefuroxime, ciprofl...
Crushed seeds of the Moringa oleifera tree have been used traditionally as natural flocculants to clarify drinking water. We previously showed that one of the seed peptides mediates both the sedimentation of suspended particles such as bacterial cells and a direct bactericidal activity, raising the possibility that the two activities might be related. In this study, the conformational modeling ...
The catalytic inactivation of Escherichia coli in water by a cerium (Ce)-promoted silver-loaded aluminum phosphate (Ag/ AlPO4) catalyst using molecular oxygen was investigated. With optimum Ce content, the Ag(Ce)/AlPO4 catalyst exhibited strong bactericidal activity. The process of decomposition of the cell wall and cell membrane was directly observed by TEM. The different morphological changes...
