| Popis: | Dra. Teresa Morales M.Viral participation in lower respiratory tract infectionsThis study viral on participation in low acute respiratory tract infections (ARI) in 344 infants under 2 year ofage was carried between years 1983 through 1985, by means of antigen detection and serological tests. A globalpositive isolation, was confirmed in 59.6% of cases (n = 205) with respiratory syncytial virus (RSV: n = 134;65.4%), adenovirus (Ad: n = 41; 20.0%) and parainfluenza viruses (PI: n = 25; 12.7%) as the most commonlyfound agents. Mixed viral infections were detected in 16.6% of cases (n = 34). RSV showed the highest prevalencein all groups, mainly in patients under six months of age. PI increased with patient's age and similar but less notice-able raise ocurred in Ad infections. RSV was the only pathogen detected in infants with bronchial obstructivedisease and was the prevalent organism in patients with all the other forms of disease. Ad and PI were equally foundin all clinical syndrome without striking differences among each other. Influenza and citomegalovirus were alsodetected, but not clear evidence of pathogenic role was obtained for the later. Immunofluorescence was the besttechnique for RSV identification while isolation was better for Ad, The relevance of these viruses as causative agentsof low ARI is confirmed and the need to further investigate other non viral etiologic agents is stressed.(Key words: respiratory tract infections, viral, acute, lower, respiratory syncytial virus, parainfluenza virus, adeno-virus).Las infecciones respiratorias agudas son causa epidemiologicos en nuestro pai's; en el lactanteextraordinariamente frecuente de morbilidad y entre 28 dias y 11 meses de edad constituyenmortalidad en el lactante en todo el mundo |
