title: NDV-O agglutinins in Mycoplasma pneumoniae infections: association with pneumonia.
abstract: Agglutinins against human O erythrocytes modified by the B1 strain of Newcastle disease virus were studied in paired sera of 148 patients with a 4-fold or greater rise in complement-fixing M. pneumoniae antibodies. The proportion of cases with a significant rise in NDV-O agglutinins was higher agmong the patients with pneumonia than among those with neurological or other clinical manifestations.
