Experience in setting up an inexpensive microbiology laboratory in the Bangladesh National Society for the Blind Eye Hospital and Training Complex at Chittagong is presented, together with the results of a pilot study to identify organisms responsible in 33 consecutive cases of suppurative keratitis in the Chittagong area of Bangladesh. Of the 33 cases 21 were positively identified by means of ...
Plant-microbial interactive relations with respect to determine mycoflora of the Sorbus domestica L.--fruits, crust, leaves and pollen were studied in 2 Slovak regions. On the fruit samples the genera Alternaria, Botrytis, Cladosporium, Mucor and Penicillium occurred, on the leaves the genera Alternaria, Cladosporium and Penicillium prevailed and on crust the genera Alternaria, Cladosporium, Pe...
A total of 84 medicinal plant samples and spices were examined for the contamination of molds and mycotoxins. Ten fungal genera of different taxonomic groups were detected. Aspergillus flavus, A. parasiticus, A. niger, Fusarium oxysporum, and Penicillium viridicatum occurred most often on the medicinal plant samples. Direct determination of mycotoxins in medicinal plant samples revealed aflatox...
Background: Aspergillus species are occasionally associated with human infections. It is essential to find a rapid and reliable method to identify these fungi and can be useful for screening the disease and also epidemiological aims. Materials and Methods: Our subjects included Aspergillus species isolated from clinical and environmental sources of four Iranian educational hospitals. Aspergilli...
Microbial transformations of racemic 7-hydroxyflavanone using strains of genus Aspergillus (A. niger KB, A. niger 13/5, A. ochraceus 456) and the species Penicillium chermesinum 113 were studied. The products of O-methylation, O-methylation along with hydroxylation at C-3' and C-4', reduction of the carbonyl group, reduction of the carbonyl group along with hydroxylation at C-5, and dehydrogena...
