“…Stallybrass concluded that workers in such industries suffer no additional risk of contracting aspergillosis. Duinner, Hardy, Nakielny, Robinson, and Smart (1958), reporting on necropsy findings in five men out of a total of 31 employed in handling grain and flour, found no evidence of pulmonary aspergillosis.…”

“…It seems that this disease does not result from inhalation of an atmosphere associated with a catch-rate for aspergilli of 3-0 per minute or less. It may have been for this reason that Dunner et al (1958) failed to associate fungi of any genus with 30 out of 31 grain workers who had had chest symptoms. In the single case in which fungi were demonstrated in the lungs at autopsy identification was not complete, and the fungus was not an aspergillus.…”

“…Similarly, Dunner, Hermon, and Bagnall (1946), who studied the lung changes in the grain dockers of Hull, found no aspergillosis. Dunner, Hardy, Nakielny, Robinson, and Smart (1958) examined 31 men who habitually handled grains of all sorts and in none of these was there evidence of pulmonary mycosis. There is no doubt that moulds flourish in grain, and that persons exposed to grain sometimes develop pulmonary aspergillosis; nevertheless, such an event seems to be rare, and there is only one recorded case of compensation being awarded to a man who developed aspergillosis after working with hay, grain, and corn for more than 20 years (Ford v. Union Stock Yards, 1942).…”

A Study of Aspergillus Spores in the Atmosphere of a Modern Mill

A study has been made of the atmospheric pollution by aspergillus spores of a large animal provender mill in which various grains are unloaded, stored, and processed, and a comparison has been made with the degree of pollution of the urban atmosphere in the neighbourhood. The catch-rate of the spores in the normal working atmosphere of the mill has been found to be 30 times higher than that obtained in the urban atmosphere, and for this reason the health record of a group of operatives has been considered with particular reference to the occurrence of pulmonary aspergillosis. Despite the risk of exposure within the mill no evidence has been found of an increased liability to develop the disease.The particular groups of aspergilli isolated by culture during this study have all been reported to have been associated with aspergillosis in man, and the relevant papers give evidence of a pathogenic rather than a saprophytic role. The study therefore provides quantitative data relating atmospheric spore content and the risk of pulmonary infection in man, a subject which as yet has received little attention.In this study it has been found that of all the grains handled in the mill, maize is associated with the highest degree of contamination, so that the aspergillus spores in the atmosphere of the mill may have originated chiefly from this source.

“…However, Macartney (1964) reviewed the original work performed in Paris 1890-1897 and was not convinced that there was any real evidence linking pulmonary aspergillosis and certain occupations. Stallybrass (196 I) and Dunner et al (1958) studied men working with flour and grain and found no evidence of pulmonary aspergillosis, though atmospheric pollution with Aspergillus spores was very high.…”

Mycotic infections continue to play an increasingly important role in the practice of medicine and particula rly in pulmonary disease.The histo ry of Aspergillus infection of the lung has been tr aced from the first recognised case to modern conc epts regarding the va rying ways in which the fungu s can manifest itself.The evidence for the possible aetiologies of the tumour-like form of pulmonary aspergillosis-the aspergilloma -has been presented . This has dem o nstrated the saprophytic nature of the infection with under lying pre -existing lung disease in the vast major ity of cases.T he role of corticosteroids. immunosuppressive drug s a nd anti biotic s is con sidered to be of importance
