The fluorescence method of detecting aflatoxin-producing strains of Aspergillus flavus and related species utilizes the ultraviolet-induced fluorescence of aflatoxin produced in a modified Czapek's solution agar containing corn steep liquor, HgCl(2), and (NH(4))H(2)PO(4) instead of NaNO(3). The presence of aflatoxin is confirmed by thin-layer chromatography(More)
Fifty-two isolates of Penicillium viridicatum Westling were divided into three groups based on ability to produce ochratoxin and/or citrinin, color, growth rate, type of growth, odor, and isolation source. Members of group I resemble one of the representative strains of P. viridicatum described in the literature; those belonging to group II differ from(More)
epidemiology incidence Malignant pleural mesothelioma (MPM) is considered to be a relatively rare tumour. In Great Britain, the incidence in males is 3.4/100 000, in France it is 2.3/100 000 and in the Netherlands it is 3.2/100 000. In the last 10 years, the incidence of MPM has increased slightly, mainly due to the lag time of 30–50 years after exposure to(More)
