قارچ aspergillus parasiticus ، یکی از مهمترین عوامل فساد محصولات کشاورزی و مواد غذایی است و دارای پراکنش وسیع جهانی می باشد. این قارچ از محصولاتی چون پسته، بادام، ذرت، بادام زمینی، گندم و پنبه دانه جداسازی و معرفی شده است. به علاوه یکی از مهمترین دلایل تحقیقات فراوان روی این قارچ توانایی تولید زهرابه آفلاتوکسین است که سرطان زایی آن به اثبات رسیده است. آفلاتوکسین از جنبه بهداشتی و اقتصادی بسیار ...

BACKGROUND Craniopagus parasiticus is rare with an incidence of approximately four to six cases in 10,000,000 births. In our case, the head of the parasitic twin protruded from the temporal area of the normal twin's cranium. The parasitic twin had two deformed lower limbs, of which one was rudimentary, and long bones of the bilateral lower limbs and some pelvic bone. Dissection of the mass of t...

Tolnaftate [2-napthyl-N-methyl-N-(m-tolyl)thionocarbamate], an antifungal drug, is widely used to control superficial fungal infections in humans and other animals. In this study the effect of tolnaftate on aflatoxin biosynthesis by Aspergillus parasiticus NRRL 3240 was investigated. Tolnaftate changed the morphology of A. parasiticus to yeastlike forms and inhibited aflatoxin formation. The fo...

Aflatoxins are toxic and carcinogenic polyketide metabolites produced by certain fungal species, including Aspergillus flavus and A. parasiticus. Many internal and external factors, such as nutrition and environment affect aflatoxin biosynthesis; therefore, we analyzed the transcriptome of A. flavus using expressed sequence tags (ESTs) from a normalized cDNA expression library constructed from ...

Two distinct reservoirs of mycotoxins exist in fungal-infected cereal grains--the fungal spores and the spore-free mycelium-substrate matrix. Many fungal spores are of respirable size and the mycelium-substrate matrix can be pulverized to form particles of respirable size during routine handling of grain. In order to determine the contribution of each source to the level of mycotoxin contaminat...

Aflatoxins are cancer-causing, immuno-suppressive mycotoxins that frequently contaminate important staples in Zambia including maize and groundnut. Several species within Aspergillus section Flavi have been implicated as causal agents of aflatoxin contamination in Africa. However, Aspergillus populations associated with aflatoxin contamination in Zambia have not been adequately detailed. Most o...

objective: aflatoxin is important in the food industry, in animal husbandry and the medical area; there are enormous negative economic impacts due to this toxin. numerous studies have researched extracts and plant compounds with the intent to reduce the growth of aflatoxin-producing organisms, inhibit toxin production and suppress the major toxin encoded genes (i.e., aflr) in these organisms. l...

background : aflatoxins (afs) are secondary hazardous fungal metabolites that are produced by strains of some aspergillus species on food and feedstuffs. aflatoxin b 1 (afb 1 ) is one of the most important af with high toxicity. prevention of af production and their elimination from food products is a matter of importance for many researchers in the last decades. nanomaterials applications in m...
