toxigenic aspergillus flavus and aflatoxins in sri lankan medicinal plant material.the fungal flora of 6 asian medicinal plants, aerva lanata (linn.) juss. alyssicarpus vaginalis d.c., tribulus terrestris linn. adhatoda vasica nees., centella asciatica (l.) urb., cardiospermum halicacabum linn. was determined. after surface disinfection aspergillus spp. were most frequently observed. aspergillus flavus, isolated from alyssicarpus vaginalis and aerva lanata produced aflatoxins in culture. aflatoxin b1 was also detected in a sample of aerra lanata at a level of 0.5 micrograms/g. ...19911906136
fungi associated with dried fish in sri lanka.the mycoflora of dried-salted fish from markets in kandy, sri lanka was studied with emphasis on visibly spoiled dried fish. a total of 61 fungal isolates from 25 dried-fish were isolated and identified. the most prevalent fungus was aspergillus niger. species of aspergillus flavus, a. fumigatus, a. glaucus, a. restrictus, aureobasidium spp. basipetospora halophila (a genuinely halophilic fungus) cladosporium herbarum, gliomastix, spp., penicillium chalybeum and penicillium expansum were present ...19902233981
survey of mycotic and bacterial keratitis in sri lanka.over a two-year period (1976-1977 and 1980-1981), 66 cases of bacterial and mycotic cases of keratitis were diagnosed in the eye clinic of the general hospital in kandy, sri lanka. the clinical and microbiologic aspects of these cases are described. noteworthy was the first known human case caused by paecilomyces farinosus, a geophilic species, commonly encountered as an insect parasite throughout the world. the bacterial and the other fungal etiologic agents isolated and identified were: pseudo ...19947984216
microbiological quality of desiccated coconut.a microbial survey of sri lankan desiccated coconut has been made on material purchased in supermarkets in sheffield or on material obtained directly from the processing company. the total viable count (tvc) was reduced by spoilage and pasteurization from 10(4)/g to 10(3)/g. most samples contained low levels of coagulase-positive staphylococcus aureus suggesting that this commodity had been handled during production. one focus of contamination with aspergillus flavus was found for each 8.34 g of ...19863081627
a mycological and bacteriological survey on feed ingredients and mixed poultry feeds in reunion island.a survey was carried out in reunion island to obtain data on the occurrence of fungi, aflatoxigenic strains of aspergillus flavus, aflatoxins, total aerobic bacteria and salmonellae of 150 samples of mixed poultry feeds and raw materials. these were collected at five farms over a 3-month period during the warm rainy season. white corn and braizlian soybean meal seemed to present a better microbiological quality than yellow corn and us soybean meal. mixed poultry feeds presented a high total mold ...19902112690
effect of parboiling and bran removal on aflatoxin levels in sri lankan rice.commercial parboiling of rice in sri lanka and many south asian countries provides ideal conditions for the occurrence of aflatoxins because the rice is steeped (allowing fermentation) thus providing ideal conditions for growth of toxigenic aspergillus species. however the traditional 'cottage' method of parboiling rice, which does not involve steeping, appears to reduce aspergillus growth even after long storage periods. preferential infection of parboiled rice by aspergillus flavus was observe ...19911922267
