allergic bronchopulmonary aspergillosis in a cane-sugar mill.allergic bronchopulmonary aspergillosis is reported in two (1.5%) of 131 workers occupationally exposed to aspergillus fumigatus at the u.d. sugar mills, shamli. twelve of the workers revealed type i (9.2%) and three (2.8%) type iii skin hypersensitivity against with fungus. serum preciptins were demonstrated in two out of 44 workers and positive sputum cultures in 26 out of 58 workers. it is suggested that constitutional predisposition of the host may be a more important factor than the extent ...1977329408
mycotoxins produced by aspergillus fumigatus species isolated from molded silage. 1977328548
maize silage: incidence of moulds during conservation.the basic principle of silage making--preservation under anaerobiosis--is recognized. with this environment the substrate can harbour a spontaneous and active microflora that can be divided into two sequential phases; a bacterial phase followed by a yeast phase. the imperfections of the techniques used in making silage, however, frequently result in invasion by fungi. the moulds that are responsible for serious changes (loss of nutrients, mycotoxins) are classified into a dozen characteristic di ...1977328359
[incorporation of glycine and serine in sideramines of the ferrichrome type with fungi of the genus aspergillus in vivo and in vitro (author's transl)].a 1.6-11.8% incorporation of labelled glycine and serine into ferrichrome, ferricrocin and ferrichrysin has been achieved with four strains of aspergillus in vivo. cell-free extracts of aspergillus fumigatus and a. quadricinctus capable of cyclohexa-peptide biosynthesis have been prepared.1977327964
surgical treatment of pulmonary aspergilloma.fourteen patients with aspergilloma (fungus ball) were reviewed. hemoptysis was the major symptom (93%). chest roentgenograms disclosed a "fungus ball" in every patient, and the mycelia of aspergillus fumigatus were recovered from all resected specimens. one of three patients treated by pneumonectomy died post-operatively. a lobectomy was performed in ten patients, and segmental resection in one without mortality or significant morbidity. there has been no evidence of recurrence in a follow up o ...1977327952
paranasal aspergilloma caused by an albino variant of aspergillus fumigatus.an unusual case of aspergilloma in the maxillary sinus caused by an albino variant of aspergillus fumigatus var ellipticus is presented. removal of the fungus ball by a left caldwell-luc procedure resulted in complete recovery for the patient. this case is the 17th culturally proven case of paranasal aspergilloma caused by a fumigatus, the third case reported from the united states, the first case due to aspergillosis caused by an albino strain of a fumigatus.1977327569
