Title Clinical and epidemiological study of 17 cases of farmer's lung disease
Bibliographic information June 1985, Vol.23, No.6, p.679-690. Illus. 33 ref.
Abstract Clinical characteristics of 17 patients with farmer's lung disease were investigated. All patients were engaged in dairy farming and the average history of dairy labour was 12.6 years. The onset of symptoms was concentrated in winter when they fed stored hay to their cattle. Eleven patients had antibodies against Micropolyspora faeni and 8 had antibodies against Thermoactinomyces vulgaris (5 patients tested were positive for both organisms). Epidemiological studies concerning farmer's lung disease were investigated in the dairy farming population in the northern part of Iwate prefecture. The prevalence of antibodies to farmer's lung antigens was 3.5% and the most prevalent antibody type was against Micropolyspora faeni. Precipitin-positive farmers had greater numbers of cattle than did precipitin-negative farmers.
