In this study, the role of intercellular adhesion molecule 1 (ICAM-1) in the pathogenesis of Pseudomonas aeruginosa keratitis was examined by using inbred ICAM-1-deficient knockout mice. These mice had significantly less (P </= 0.02) ocular disease than wild-type mice, suggesting that ICAM-1 contributes to a more severe disease response following P.(More)
Eleven isolates obtained from a laboratory sewage treatment plant, most of them presumptively assigned to the coryneform genera Curtobacterium and Aureobacterium were studied for the presence of intracellular polyphosphates and polyphosphate dependent enzymes. All isolates stored polyphosphates and showed adenylate kinase activities ranging from 64 to 815(More)
