title: Chronic bronchitis. IV--Antibody titres to bacterial antigens during acute exacerbations.
abstract: In 49 patients of chronic bronchitis with acute exacerbation, serum antibody titres were estimated against the respective pathogen isolated and cultured from sputum of individual patients. Antibody titres to Klebsiella and Staphylococcus coagulase positive organisms were found in 28 and 25 patients respectively. Paired serum samples from 21 patients showed rising antibody titres in 17 of them, whereas the antibody titres fell in the remaining 4 patients. Notably, only 2 patients demonstrated a four fold rise or fall in the antibody titres. The significance of these findings is discussed.
