Dust was collected over a period of several weeks in 2007 from HEPA filters in the U.S. Laboratory Module of the International Space Station (ISS). The dust was returned on the Space Shuttle Atlantis, mixed, sieved and the DNA was extracted. Using a DNA-based method called mold-specific quantitative PCR (MSQPCR), 39 molds were measured in the dust. Potential opportunistic pathogens Aspergillus ...
Isolates of Aspergillus chevalieri, A. flavus, A. ochraceus, A. repens, and Penicillium funiculosum and complexes of P. citrinum-P. implicatum isolated from moldy pecan meats were toxic to chicks.
Aflatoxins are highly toxic cancer causing fungal metabolites known to cause immune-system suppression, growth retardation, liver disease, and death in both humans and domestic animals. Human exposure to aflatoxins is limited by regulations that prohibit the use of crops containing excess quantities of aflatoxins for foods and feeds. Aflatoxins are regulated in part per billion (ppb) ranges wit...
سیچلاید اوراتوس (Melanochromis auratus) از پرطرفدارترین ماهیان زینتی میباشد. این گونه همانند سایر ماهیان در معرض انواع بیماریها بوده و بیماریهای قارچی از متداولترین بیماریهای این گونه هستند. این مطالعه با هدف بررسی و شناسایی قارچهای پوستی در مزارع پرورش ماهیان زینتی استان مازندران (ساری، آمل و بهشهر) انجام شد. از هر کارگاه تعداد 15 عدد ماهی بهصورت تصادفی نمونهگیری شد. نمونههای پوست در ...
Understanding the nature of species" boundaries is a fundamental question in evolutionary biology. The availability of genomes from several species of the genus Aspergillus allows us for the first time to examine the demarcation of fungal species at the whole-genome level. Here, we examine four case studies, two of which involve intraspecific comparisons, whereas the other two deal with intersp...
Fungal species of the genus Aspergillus play significant roles as model organisms in basic research, as "cell factories" for the production of organic acids, pharmaceuticals or industrially important enzymes and as pathogens causing superficial and invasive infections in animals and humans. The release of the genome sequences of several Aspergillus sp. has paved the way for global analyses of p...
Conidia of domesticated yellow-green aspergilli from strains of Aspergillus oryzae (Ahlburg) Cohn and Aspergillus sojae Sakaguchi and Yamada ex Murakami, used in the preparation of koji inoculum, germinate approximately 3 h sooner than conidia produced by related wild species, Aspergillus flavus Link ex Fr. and Aspergillus parasiticus Speare. There was no consistent relationship between average...
To find out the prevalence of Aspergillus spp. in Bronchoalveolar Lavages (BALs) of pulmonary tuberculosis patients, to study the anti-Aspergillus antibodies in patient’s sera and to study the anti-fungal susceptibility of the isolated Aspergillus strains. BALs obtained from sixty-five patients of pulmonary tuberculosis and 10 healthy volunteers were studied. Direct microscopy was performed by ...
A case of Enterococcus raffinosus nosocomial sinusitis which appeared to complicate a previous Aspergillus flavus paranasal infection is presented. This uncommon enterococcal species is rarely responsible for human diseases, and has never previously been associated with sinusitis.
Aflatoxins are secondary metabolites produced by Aspergillus flavus, A. parasiticus, A. tamari, A. bombycis and A. nomius species. Relative humidity (RH) is one of the most important parameters influencing the development of aflatoxins in pistachio orchards by Aspergillus species. The type of irrigation system affects density and frequency of the Aspergillus species in the soil. In the current ...
