More common in emphysema, bronchiectasis, tuberculosis and other lung diseases, recently also common in Pneumocystis carinii pneumonia, cytomegalovirus pneumonia and AIDS. According to Japanese studies, the incidence of atypical acid-fast bacilli in every 100,000 in 1971 was 0.89, 1.92 in 1978 and 1.62 in 1983. Acid-fast bacteria clinical symptoms resemble tuberculosis, difficult
