Brucella-Salmonella lipopolysaccharide chimeras are less permeable to hydrophobic probes and more sensitive to cationic peptides and EDTA than are their native Brucella sp. counterparts
Freer, Enrique; Moriyón, Ignacio; Pizarro Cerda, Javier; Weintraub, Andrej; Gorvel, Jean Pierre; Moreno, Edgardo (American Society for Microbiology, 1996-08-12)A rough (R) Brucella abortus 45/20 mutant was more sensitive to the bactericidal activity of polymyxin B and lactoferricin B than was its smooth (S) counterpart but considerably more resistant than Salmonella montevideo. ... -
R-Ras Glucosylation and Transient RhoA Activation Determine the Cytopathic Effect Produced by Toxin B Variants from Toxin A-negative Strains of Clostridium difficile
Chaves-Olarte, Esteban; Freer, Enrique; Parra, Andrea; Guzman-Verri, Caterina; Thelestam, Monica; Moreno, Edgardo (Universidad Nacional, Costa Rica, 2003-03)Clostridium difficile induces antibiotic-associated di-arrhea through the production of toxin A and toxin B;the former toxin has been assumed to be responsible forthe symptoms of the disease. Several toxin ... -
