      Ulloa Flores, María Teresa; Castillo D., Loriana; Solís F., Fresia; Arévalo P., Gabriela; Rojas Z., Jorge (SOC CHILENA INFECTOLOGIA, 2012-02)
      Bacterial colonization in patients with burns skin without infection and outpatient management has been poorly studied. Objective: To quantify and identify the type of bacteria that colonize healthy body areas homologous ...
    • Community-acquired pneumonia in Chile: the clinical relevance in the detection of viruses and atypical bacteria 

      Luchsinger Farías, Vivian; Ruiz Carmona, Mauricio; Zunino, Enna; Martínez, María Angélica; Machado, Clarisse; Piedra, Pedro A.; Fasce, Rodrigo; Ulloa Flores, María Teresa; Fink, María Cristina; Lara, Pamela; Gebauer, Mónica; Chávez, Fernando; Avendaño, Luis F. (group.bmj.com, 2013)
      Background Adult community-acquired pneumonia (CAP) is a relevant worldwide cause of morbidity and mortality, however the aetiology often remains uncertain and the therapy is empirical. We applied conventional and ...
    • Effect of hydrothermally synthesized titanium nanotubes on the behaviour of polypropylene for antimicrobial applications 

      Zenteno, Andrés; Guerrero, Sichem; Ulloa Flores, María Teresa; Palza Cordero, Humberto; Zapata, Paula A. (Wiley & Sons, 2015)
      TiO2 nanotubes (TiO2-Ntbs) synthesized by a hydrothermal method were used as filler to prepare polypropylene (PP) composites by melt blending. Their structural properties as well as their biocidal potential were studied. ...
    • Gastroenteritis aguda causada por Vibrio cholerae no-O1, no-O139 que porta una región homóloga a la isla de patogenicidad VpaI-7 

      Ulloa Flores, María Teresa; Porte T., Lorena; Braun J., Stephanie; Dabanch P., Jeannette; Fica C., Alberto; Henríquez A., Tania; Osorio Abarzúa, Carlos Gonzalo (Sociedad Chilena de Infectología, 2011)
      Pathogenic Vibrio cholerae isolates, the etiologic agents of cholera, generally express one of two O antigens (O1 or O139). Most environmental isolates are nonpathogenic and are referred to as “non-O1, non-O139”. However some ...
    • Isla de patogenicidad de Vibrio parahaemolyticus en cepas chilenas clínicas y ambientales 

      Núñez, Harold; Ulloa Flores, María Teresa; Guerra, Fabiola; Osorio Abarzúa, Carlos Gonzalo (Sociedad Médica de Santiago, 2009)
      Background: Most clinical isolates of Vibrio parahaemolyticus produce a major virulence factor known as the thermostable direct hemolysin (TDH). TDH is encoded by the tdh gene which is located in a genomic pathogenicity ...
    • Photocatalytic inhibition of bacteria by TiO2nanotubes-dopedpolyethylene composites 

      Yáñez, Daniela; Guerrero, Sichem; Lieberwirth, Ingo; Ulloa Flores, María Teresa; Gómez, Tatiana; Rabagliati, Franco M.; Zapata, Paula A. (Elsevier, 2015)
      Polyethylene (PE) and polyethylene-octadecene (LLDPE) composites containing titanium dioxide nano-tubes were synthesized and applied to the inhibition of selected bacteria. It was found that polymerizationrate of the ...
    • Poly(lactic acid)/TiO2 nanocomposites as alternative biocidal and antifungal materials 

      Fonseca, Carmen; Ochoa, Almudena; Ulloa Flores, María Teresa; Álvarez Duarte, Eduardo; Canales, Daniel; Zapata, Paul A. (Elsevier, 2015)
      Poly(lactic acid) (PLA) composites with titanium oxide (TiO2) similar to 10-nm nanoparticles were produced by the melting process and their main properties were evaluated. The nanoparticles are homogeneously dispersed in ...
    • Role of Neutralizing Antibodies in Adults With Community-Acquired Pneumonia by Respiratory Syncytial Virus
