Regulation of bacterial trafficking in the nasopharynx.

Abstract:

:Bacterial 'colonisation' of the nasopharynx by potential bacterial pathogens is frequent in early childhood and is frequent as part of a dynamic process in which the microbiota of the oral and nasopharynx are established. New understanding recognizes this process is evolving and that competition and likely regulation occurs among potential pathogens as well as between pathogens and commensals. Such events elicit host responses that either results in clearance or persistence within the nasal and oral pharynx. Environmental factors such as recent antibiotic usage, smoking and vaccines all impact on the success of specific bacterial species in this competition. Understanding the significant bacterial interactions as well as how bacteria work in concert to regulate density, expression of virulence factors and capacity to produce disease are likely to provide new approaches to disease prevention.

  • Immune and inflammatory response in bronchiolitis due to respiratory Syncytial Virus and Rhinovirus infections in infants.

    abstract::Bronchiolitis is a common disease in infancy, mostly due to Respiratory Syncytial Virus and Rhinovirus. In addition to acute infection, viral bronchiolitis is responsible for sequelae including recurrent wheezing and asthma. The analysis of the viral characteristics and of the pathogenesis of the infection shows diffe...
