title: Detection and genotyping of human respiratory viruses in clinical specimens from children with acute respiratory tract infections.
abstract: Respiratory virus infections are a major health concern and represent the primary cause of testing consultation and hospitalization for young children. The application of nucleic acid amplification technology, particularly multiplex PCR coupled with fluidic or fixed microarrays, provides an important new approach for the detection of multiple respiratory viruses in a single test. The aim of this study was to analyze respiratory samples from children with acute respiratory tract infection (ARTI) using a commercial array-based method (CLART(®) PneumoVir Genomica, Coslada, Spain). These tests were used to identify viruses in 281 nasopharyngeal samples obtained from children affected by ARTI. Samples were obtained form October 2008 to April 2009. Viruses were identified in 80% of the studied ARTI providing useful information on clinical features and epidemiology of specific agents affecting children in cold months. Multiple viral infections were found in 33.45% of the specimens.
