    • Genetic variability of human metapneumovirus isolated from Chilean children, 2003-2004 
      Escobar, Carola; Luchsinger, Vivian; De Oliveira, Danielle Bruna; Durigon, Edison; Chnaiderman, Jonás; Avendaño, Luis F. (2009)
      Human metapneumovirus (hMPV) is a significant cause of acute lower respiratory tract infection in all age groups, particularly in children. Two genetic groups and four subgroups of hMPV have been described. They co-circulate ...
    • Genome type analysis of chilean adenovirus strains isolated in a children's hospital between 1988 and 1990 
      Kajon, Adriana E.; Larrañaga, Carmen; Suárez, Mónica; Wadell, Göran; Avendaño, Luis F. (1994)
      In a study designed to evaluate the genetic variability of adenovirus strains associated with infantile cases of respiratory disease requiring hospitalization, a collection of 136 adenovirus isolates obtained in the Roberto ...
    • Identification of P1 types and variants of Mycoplasma pneumoniae during an epidemic in Chile 
      Martínez, María A.; Ruiz, Mauricio; Zunino, Enna; Luchsinger, Vivian; Aguirre, Raúl; Avendaño, Luis F. (2010)
      This study was conducted to determine the types of M. pneumoniae prevalent in adults presenting with community-acquired pneumonia during an epidemic period, and to scrutinize a variable region of the RepMP4 element for the ...
    • Impaired immune response in severe human lower tract respiratory infection by respiratory syncytial virus 
      Larrañaga, Carmen L.; Ampuero, Sandra L.; Luchsinger, Vivian F.; Carrión, Flavio A.; Aguilar, Nelson V.; Morales, Pamela R.; Palomino Montenegro, María Angélica; Tapia, Lorena F.; Avendaño, Luis F. (Lippincott Williams and Wilkins, 2009)
      Background: Respiratory syncytial virus (RSV) is a major cause of acute lower respiratory infection in infants. The immune response plays a leading role in the severity of the disease. We hypothesized that severe RSV disease ...
    • Molecular epidemiology of adenovirus acute lower respiratory infections of children in the South Cone of ... 
      Kajon, Adriana E.; Mistchenko, Alicia S.; Videla, Cristina; Hortal, Maria; Wadell, Göran; Avendaño, Luis F. (1996)
      A collection of 165 adenovirus strains isolated from nasopharyngeal aspirates of children hospitalized for acute lower respiratory infection in Argentina, Chile, and Uruguay between 1991 and 1994 was studied by restriction ...
    • Prevalence of astrovirus infection among Chilean children with acute gastroenteritis 
      Gaggero Brillouet, Aldo; O'Ryan Gallardo, Miguel; Noel, Jacqueline S.; Glass, Roger I.; Monroe, Stephan S.; Mamani, Nora; Prado Jiménez, Valeria; Avendaño, Luis F. (1998)
      The frequency of astrovirus infection in 456 Chilean children with diarrhea was determined by enzyme-linked immunosorbent assay, reverse transcriptase PCR, and cell culture. Astrovirus was detected in 16.5% of rotavirus-negative ...
    • Respiratory syncytial virus infection in infants is associated with predominant Th-2-1ike response 
      Román, Mariana; Calhoun, William J.; Hinton, Kim L.; Avendaño, Luis F.; Simon, Valeska; Escobar, Ana M.; Gaggero Brillouet, Aldo; Díaz, Patricia V. (American Thoracic Society, 1997)
      Viral infections have been associated with cellular immune responses and production of Th-1 cytokines. Respiratory syncytial virus (RSV), however, induces virus-specific IgE, which might be a consequence of a Th-2-like ...
    • Treatment of respiratory syncytial virus infection with vitamin A: A randomized, placebo-controlled trial ... 
      Dowell, Scott F.; Papic, Zdenka; Bresee, Joseph S.; Larrañaga, Carmen; Mendez, Miguel; Sowell, Anne L.; Gary, Howard E.; Anderson, Larry J.; Avendaño, Luis F. (1996)
      Background. Treatment with high dose vitamin A reduces complications and duration of hospitalization for children with measles. In respiratory syncytial virus (RSV) infection, as with measles, low serum vitamin A concentrations ...
