    • DNA, Cell Wall and General Oxidative Damage Underlie the Tellurite/Cefotaxime Synergistic Effect in Escherichia ... 
      Molina Quiroz, Roberto C.; Loyola, David E.; Muñoz Villagrán, Claudia; Quatrini, Raquel; Vásquez, Claudio C.; Pérez Donoso, José (PLoS ONE 8(11): e79499, 2013)
      The constant emergence of antibiotic multi-resistant pathogens is a concern worldwide. An alternative for bacterial treatment using nM concentrations of tellurite was recently proposed to boost antibiotic-toxicity and a ...
    • Enhancing the antibiotic antibacterial effect by sub lethal tellurite concentrations: Tellurite and cefotaxime ... 
      Molina Quiroz, Roberto C.; Muñoz Villagrán, Claudia; de la Torre, Erick; Tantaleán, Juan C.; Vásquez, Claudio C.; Pérez Donoso, José (2012)
      The emergence of antibiotic-resistant pathogenic bacteria during the last decades has become a public health concern worldwide. Aiming to explore new alternatives to treat antibiotic-resistant bacteria and given that the ...
    • Exposure to sub-inhibitory concentrations of cefotaxime enhances the systemic colonization of Salmonella ... 
      Molina Quiroz, Roberto C.; Silva, Cecilia A.; Molina, Cristian F.; Leiva, Lorenzo E.; Reyes Cerpa, Sebastián; Contreras, Inés; Santiviago Cid, Carlos (Royal Soc., 2015)
      It has been proposed that sub-inhibitory concentrations of antibiotics play a role in virulence modulation. In this study, we evaluated the ability of Salmonella enterica serovar Typhimurium (hereafter S. Typhimurium) to ...
    • Microarray analysis of the Escherichia coli response to CdTe-GSH Quantum Dots: Understanding the bacterial ... 
      Monrás, Juan P.; Collao, Bernardo; Molina Quiroz, Roberto C.; Pradenas, Gonzalo A.; Saona, Luis A.; Durán Toro, Vicente; Órdenes Aenishanslins, Nicolás; Venegas, Felipe A.; Loyola, David E.; Bravo, Denisse; Calderón, Paulina F.; Calderón, Iván L.; Vásquez, Claudio C.; Chasteen, Thomas G.; López, Desiré A.; Pérez Donoso, José M. (BioMed Central, 2014)
      Background: Most semiconductor nanoparticles used in biomedical applications are made of heavy metals and involve synthetic methods that require organic solvents and high temperatures. This issue makes the development of ...
