Abstract

Frequency and kind of species of atypical mycobacteria isolated from patients hospitalized in thirteen participating hospitals in June, September, and December 1977, and March 1978 were studied using p-nitrobenzoic acid-Ogawa egg medium as a screening medium. Data were taken from the results of monthly sputum examinations in the above months. Futhermore, patients with lung disease due to atypical mycobacteria hospitalized in the study year, April 1977 to March 1978, were the sub jects of the present study.<BR>1) Atypical mycobacteria were found at a rate of 9.5% among all mycobacteria including M. tuberculosis (Table 1). The kind of species of the atypical mycobacteria isolated are shown in Table 2.<BR>2) A total of 159 patients with lung disease due to atipical mycobacteria were found in the study year (Table 4). Frequency of the patients were considered to be high in the Tokyo, Kanagawa, and Kinki (Osaka) hospitals (Table 5).<BR>3) Frequency of isolation of atypical mycobacteria from sputum specimens of the patients in the participating hospitals has appeared to be increasing (Table 7). However, no significant changes were found in the kind of the species of atypical mycobacteria isolated in various years (Table 8).<BR>4) In contrast to that the number of tuberculous patients is decreasing, the number of patients with lung disease due to atypical mycobacteria is increasing (Table 9). The kinds of species of atypical mycobacteria which cause the diseases in patients were similar in various study years (Table 10).
