primary cutaneous aspergillosis in six leukemic children.we report a cluster of primary cutaneous aspergillosis in six children with hematologic malignancy. when first seen, they had hemorrhagic bullae caused by aspergillus flavus, aspergillus fumigatus, and aspergillus niger at the sites of insertion of intravenous cannulas or where arm boards had been taped to the extremities. rapid diagnosis of cutaneous aspergillosis was made by direct examination of the blister roof with potassium hydroxide before it progressed to a necrotic ulcer. intravenous am ...19853855880
symposium on infections in the compromised host. the leukemias.the treatment of acute leukemia in the adult causes prolonged and profound granulocytopenia. when the patient has less than 100 granulocytes per microliter, the risk of life-threatening infection is extremely high. major infections include bacteremia, pneumonia, pharyngitis, esophagitis, colitis, perianal or perirectal lesions, and cellulitis. the major organisms are gram-negative bacilli (especially pseudomonas aeruginosa, escherichia coli, and klebsiella pneumoniae), gram-positive organisms (s ...19853919366
interaction between streptococcus lactis and aspergillus flavus on production of aflatoxin.the inoculation of aspergillus flavus spores into a culture of streptococcus lactis in lablemco tryptone broth medium resulted in little or no aflatoxin accumulation even though the growth of the fungus was not hindered. the drop in ph and reduced nutrient levels in the medium as a result of the s. lactis growth were not the cause of the observed inhibition. the inhibition was not eliminated by the addition of carbohydrate equal to the amount used by the bacterium before the inoculation with the ...19853919639
possible implications of reciprocity between ethylene and aflatoxin biogenesis in aspergillus flavus and aspergillus parasiticus.aspergillus flavus and aspergillus parasiticus produced ethylene during early growth. however, the onset of toxin biosynthesis was marked by the absence of ethylene evolution. 2-chloroethyl phosphonic acid, an ethylene-generating compound, inhibited aflatoxin biosynthesis in vivo. the reciprocal relationship between the production of aflatoxin and ethylene by the organism may indicate the involvement of the latter in the regulation of aflatoxin biogenesis.19853919643
presence of cyclopiazonic acid in kodo millet (paspalum scrobiculatum) causing 'kodua poisoning' in man and its production by associated fungi.cyclopiazonic acid was isolated and identified from a sample of kodo millet seed that caused symptoms of 'kodua poisoning' in man. the extract of the toxic grain when injected intraperitoneally into mice produced symptoms of depression and complete loss of mobility. the seed was infected by aspergillus flavus and a. tamarii and both fungi produced cyclopiazonic acid. this is the first report of the association of a mycotoxin with kodua poisoning and of a. tamarii with mycotoxicoses.19853921845
