Late killing of Plasmodium berghei in the liver by an anti-circumsporozoite protein monoclonal antibody

Manuela C. Aguirre-Botero, Olga Pacios, Susanna Celli, Eduardo Aliprandini, Anisha Gladston, Jean-Michel Thiberge, Pauline Formaglio, Rogério Amino

The paper shows that the 3D11 anti-CSP monoclonal antibody neutralizes Plasmodium berghei sporozoites in the liver after several hours, inhibiting motility and leading to parasite killing.

Molecular characteristics of phages located in Carbapenemase-Producing Escherichia coli clinical isolates: New Phage-Like Plasmids

María Cecilia López, Inés Bleriot, Olga Pacios, Laura Fernández-García, Lucía Blasco, Antón Ambroa, Concha Ortiz-Cartagena, Neil Woodford, Matthew J. Ellington, María Tomás

The paper analyzes 50 temperate bacteriophages from carbapenemase-producing E. coli isolates, classifying them into viral families and identifying functional features and potential plasmid-like properties.
