Extrinsic allergic alveolitis in Scottish maltworkers.

Abstract

W BLYTH, BSC, PHD, lecturer it was usually caused by a type 3 allergic reaction to Aspergillus clavatus.

Respiratory symptoms and pulmonary function of workers exposed to cork dust, toluene diisocyanate and conidia.

“…Those exposed to conidia ran a three times greater risk of symptoms of hypersensitivity pneumonitis. This evidence corroborates the work of Portuguese authors (1)(2)(3) who found that the inhalation of P frequentans reproduced symptoms of suberosis and that exposure to conidia implies a risk of hypersensitivity pneumonitis (41,42). Those workers with symptoms of hypersensitivity pneumonitis and fever , the latter persistent with exposure to conidia, also had precipitins to P frequentans and restrictive ventilatory impairment, which ruled out the organic dust toxic syndrome (43).…”

The Genus Aspergillus

“…Although these more modem systems speed up the process, the high level of moisture availability and the presence of solubilised and partially solubilised nutrients still favour microbial growth, although less so than floor malting (Flannigan et al, 1982). As far as malt worker's lung is concemed, Grant et al, (1976) concluded from a survey of Scottish maltings that the incidence of the disease would dimini sh with mechanisation. The survey revealed that 5.2% of all workers were affected by the disease, with almost as many workers in box maltings (6.2%) as in floor maltings (6.8%) having the disease, but where enclosed systems had been installed only 1.1% (Grant et al, 1976).…”

However, as more recent reports show, floor malting systems are still in use and play host to A. clavatus (Rabie and Lübben, 1984;Shlosberg et al, 1991).…”

Composition, in vitro Cytotoxicity, Anti-mildew and Anti-wood-decay Fungal Activities of the Fruit Essential Oil of Liquidambar formosana from Taiwan

“…These were tested in accordance with the ASTM G21, JIS Z 2911, and ATCC test method [30]. These fungi were either pathogens causing liver cancer, diseases of the genitalia, or which induced bronchitis, allergies and asthma in humans or which degraded cellulosic materials, paper, leather, and wood products [14][15][16]. Among the fungi tested, the growth of A. clavatus, A. niger, Cl.…”
