title: [Antiviral antibodies in acute laryngotracheobronchitis].
abstract: Antibodies to influenza A2, influenza B, parainfluenza 2 and 3, adenovirus and respiratory syncytial viruses were determined in thirty nine children with acute laryngotracheobronchitis; nine cases were not included in the analysis because of the presence of anticomplementary sera; 40% of cases were positive, 20% to influenza A2, 10% to influenza B (one case of double infection with influenza B and parainfluenza 2 viruses), 6.7% to respiratory syncytial virus and 3.3% to parainfluenza 2. Results are compared with previous studies done in Mexico.
