Fungal antigens as a source of sensitization and respiratory disease in Scottish maltworkers.

Mycological and serological studies were carried out as part of a survey of respiratory disease in Scottish maltworkers. 70% of stained sputum smears from 574 workers showed the presence of higher plant cells and/or myclelia, and the spores of common environmental fungi. Penicillium spp. (90%), Rhizopus stolonifer (48%) and yeasts (53%) were the dominant fungi in 699 sputum cultures, and showed a similar proportional distribution in 327 samples of grain, malt, culms and dusts from fifty-six maltings. 57% of 711 men were serologically positive for fungi, 22% for Aspergillus fumigatus, 20% for A. clavatus, 10% for A. niger, 16% for Cladosporium herbarum and over 3% for Rhizopus stolonifer, 6% of 132 men were positive for Penicillium cyclopium. No precipitating antibodies to antigens from Alternaria tenuis, Aureobasidium pullulans, Candida albicans, Geotrichum candidum, Rhodotorula glutinis or Trichoderma viride were detected in tests of forty sera. Sera from the 5.2% of men with symptoms of extrinsic allergic alveolitis showed increased reactivity to mycelial antigens from Aspergillus clavatus. The fungus was cultured from 21% of maltings, 7% of all environmental samples and from the sputa of 8% of maltworkers.

Extrinsic allergic alveolitis in Scottish maltworkers.

In a survey of respiratory disease in the Scottish malting industry 5.2% of employees were found to have symptoms of extrinsic allergic alveolitis. In most cases the disease was mild and not associated with any serious respiratory disability. It was significantly less common where modern mechanical methods of malting were used. Mycological and serological studies suggested that it was usually caused by a type 3 allergic reaction to Aspergillus clavatus.

Occupational absorption of tellurium: a report of two cases.

Industrial uses of tellurium are limited, and reported cases of tellurium absorption of occupational origin are rare. Two such cases are reported here. Both showed typical signs and symptoms of intoxication; in particular, the stench of sour garlic was noted on breath and from excreta. An unusual feature was the bluish-black discoloration of the webs of the fingers and streaks on the face and neck. Full hospital investigation was negative. No permanent damage resulted and each patient made a spontaneous recovery without treatment.
