Infections with Viruses and Mycoplasma pneumoniae during Exacerbations of Chronic Bronchitis 1978-04-17 .txt text/plain 3110 159 42 The association of viral and Mycoplasma pneumoniae infections with acute exacerbations of chronic bronchitis was studied by serologic or isolation techniques in 46 adult men during the five years from 1964 through 1968. Because of the high prevalence and morbidity of chronic bronchitis among patients of Veterans Administration Hospitals, we have conducted surveillance of one of these groups to assess the impact of respiratory tract infections on the natural course of this disease and to investigate further the occurrence and relative importance of viruses and mycoplasmas in exacerbations [3] . Evidence of viral and Mycoplasma pneumoniae infections (obtained mainly by serologic testing and to a lesser extent by isolation of organisms) was correlated with the pattern of clinical disease in patients with chronic bronchitis. pneumoniae were detected in 50 (30.1%) of 166 exacerbations of chronic bronchitis in the 46 adult patients studied (table 2) . ./cache/cord-341548-gazsszs6.txt ./txt/cord-341548-gazsszs6.txt
