Extrinsic allergic alveolitis induced by the yeast Debaryomyces hansenii.
A 65-yr-old female developed cough, fever and dyspnoea following repeated exposure to a home ultrasonic humidifier. High-resolution computed tomography showed ground-glass opacity in both lung fields. Arterial blood gas analysis gave an oxygen tension of 8.38 kPa (63 Torr). Pulmonary function testing revealed restrictive ventilatory impairment with a reduction in the diffusing capacity. The dia...
متن کامل[Extrinsic allergic alveolitis].
Extrinsic allergic alveolitis (EAA) or hypersensitivity pneumonitis is an interstitial lung disease associated with repeated exposure to a wide range of inhaled organic dusts and related occupational allergens, especially bird and fungal proteins. We focus on the diagnostic and prognostic findings related to the use of BAL in the management of EAA patients. The presentation of EAA varies from p...
متن کاملElectron microscopy of ascus formation in the yeast debaryomyces hansenii.
Ascus formation in Debaryomyces hansenii includes fusion of two cells, usually mother and daughter while still attached to each other, through short protuberances developed from the cross wall between them. Nuclear fusion takes place in the channel connecting the two cells; meiosis apparently occurs in the mother cell. Generally, only one lobe of the meiotic nucleus is surrounded by a prospore ...
متن کاملExtrinsic allergic alveolitis in the tobacco industry.
A total of 57 subjects who had been exposed to mould dust in the tobacco industry were studied. Their working environment showed exposure to spores of different moulds, and 29 subjects (51%) showed antibodies against one or more of the microbes. Fifteen (26%) had work related respiratory symptoms. Eight (14%) showed slight radiographic pulmonary fibrosis. Spirometry showed a tendency toward res...
متن کاملCopper-zinc superoxide dismutase from the marine yeast Debaryomyces hansenii.
We have isolated the cytosolic form of Cu-Zn superoxide dismutase (SOD) from the marine yeast Debaryomyces hansenii. This enzyme has a subunit mass of 18 kDa. The preparation was found to be heterogeneous by IF electrophoresis with two pI ranges: 5.14-4.0 and 1.6-1.8. The enzyme preparation had a remarkably strong stability at pH 6.0-7.0, surviving boiling for 10 min without losing more than 60...
