  author={D. R. Olvera and F. Sanchez and Carlos Cabello Guti{\'e}rrez and M. E. M. Zavala},
Acute respiratory infections are among the most frequent human pathologies and 70% of these infections are generated by viruses. Most of them cause acute respiratory infection (ARI) that are lo 
Etiología de las neumonías adquiridas en comunidad en la población infantil
The etiological diagnosis of CAP in pediatric patients is supported by laboratory tests that generate direct or indirect evidence of the causal germ, and the variety of diagnostic techniques used in clinical trials and interpretation of the results in the absence of results is questioned. Expand

Immunological determinants of disease caused by respiratory syncytial virus.

  • 1996
Various disease syndromes caused by respiratory syncytial virus may have a common mechanism of pathogenesis mediated by cytokines produced by type 2 T helper cells, and vaccination can influence the types of cytokine produced. Expand
Respiratory syncytial virus.
RSV is now understood to be the most significant viral respiratory pathogen of infants and is capable of causing both bronchiolitis and pneumonia. It is a particular risk to hospitalized infants asExpand

The interactive role of viruses and bacteria is not clear but may play a role in increased severity of respiratory infections, and crowding, inhaled pollutants, and malnutrition are likely candidates. Expand
Epidemiological aspects of antibiotic resistance in respiratory pathogens
Respiratory infections are the most frequent reason for primary health care consultation and the most common types are upper respiratory tract infections: common cold, pharyngitis, otitis media and sinusitis. Expand
Murine coronavirus infection: a paradigm for virus-induced demyelinating disease
The murine coronavirus-induced demyelinating disease in rodents is one such model for demyeling disease in humans and provides insights into potential mechanism(s) involved in the disease process. Expand
Association of Rhinovirus Infections with Asthma
Current information on immune responses to rhinovirus infection and potential connections between antiviral responses and preexisting allergic inflammation are outlined and current and future strategies for treating rhinvirus infections and virus-induced exacerbations of asthma are discussed.

The appearance of cell-bound IgE in respiratory-tract epithelium after respiratory-syncytial-virus infection.
Persistence of IgE in the respiratory tract may explain the recurrent episodes of wheezing that occur in many patients after RSV-induced bronchiolitis and the subsequent release of chemical mediators of bronchospasm. Expand
Respiratory syncytial virus induces selective production of the chemokine RANTES by upper airway epithelial cells.
RANTES (regulated upon activation, normal T cell-expressed and -secreted), which was present in negligible concentrations in uninfected cultures, was strongly induced by RSV infection, in a dose- and time-dependent manner. Expand
Respiratory infections and asthma.
The possible mechanisms of virus-associated airway hyperresponsiveness are reviewed, including the complex interplay of IgE-dependent reactions, changes in autonomic nervous system function and inflammation, epithelial damage, effects of viruses on the cellular immune response, and enhanced late-phase response.
