The presence of toxin-producing fungi in foodstuffs and other agricultural commodities is well established (1-3). The Alternaria, Aspergilli, Fusaria and Penicillia have been repeatedly implicated as the pnncipal coinhabitants of products in which toxicity has been demonstrated (4,5). Numerous compounds have been isolated that can explain the toxicity of the Aspergilli, Fusaria, and Penicillia....

the aim of this study was identification of fungi in indoor and outdoor of asthmatic patients´ home environment. opened plates (containing of malt extract agar media) were used for isolation of fungi in the air of indoor (n=360) and outdoor (n=180) of 90 asthmatic patients̉ home living in the city of sari at the level of breathing height. plates were incubated in room temperature for 7-14 days. ...

Small-spored Alternaria have been isolated from a wide variety of food crops, causing both economic losses and human health risk due to the metabolites produced. Their taxonomy has been discussed widely, but no scientific consensus has been established in this field to date. Argentina is a major exporter of agricultural products, so it is essential to thoroughly understand the physiological beh...

During the study on endophytic fungi of stone fruits including apricot, peach and nectarine in W Azarbaijan (NW Iran), a large number of isolates with Alternaria characteristics were isolated from different parts of these plants and studied taxonomically. Isolation was made based on endophytic fungal isolation method and following surface sterilization procedure. From 100 different plant sample...

Plant growth-promoting fungi (PGPF) have attracted considerable interest as bio-fertilisers due to their multiple beneficial effects on plant quantity and quality and their positive relationship with the ecological environment. Advancements in the development of PGPF for crops and economic plant cultivation applications have been achieved, but such improvements for the use of PGPF with popular ...

Occurrence of toxigenic molds and mycotoxins on dried fruits is a worldwide problem, but limited information is available in China. A total of 220 dried fruits (raisins, dried apricots, dates and wolfberries) purchased from China were analyzed for 17 mycotoxins (i.e., Alternaria toxins, ochratoxin A (OTA), patulin (PAT) and trichothecenes) by UPLC-MS/MS, combined with a single-step cleanup. The...

The aim of this study was to monitor the mycobiota of wine grapes, occurrence of ochratoxigenic microfungi in wine grapes and occurrence of ochratoxin A and Alternaria mycotoxins in fresh grape juice, must and wine from domestic crops in the year 2004. Thirteen samples of wine grapes (white /nine samples/ and red /four samples/) were collected during harvesting in the Znojmo wine region, SE Mor...

Alternariaster was erected in 2007 to accommodate Alternaria helianthi, a fungal species known to cause leaf spots on Helianthus annuus (sunflower). It was segregated from Alternaria based on conidial morphology. Recently an unknown alternaria-like dematiaceous fungus was found associated with leaf spots on Bidens sulphurea (yellow cosmos) in Brazil. Based on a multi-gene phylogeny of parts of ...

The genus Alternaria Nees ex Fr. (Dematiaceae) contains a number of species pathogenic to econom­ ically important crop plants [1]. Perhaps not unre­ lated to this is the fact that the Alternaria are a rich source of biologically active secondary metabolites [2], several of which are phytotoxic [3]. In fact, with the possible exception of the genus H elm inthosporium Link ex Fries, more phytoto...

BACKGROUND Rhinitis is a very common disease, frequently caused by sensitisation to inhalant allergens. Negative results from skin prick tests (SPT) and in vitro IgE tests generally lead to a diagnosis of non-allergic rhinitis. However, it is possible, as indicated by studies addressed with dust mites or pollens that the production of specific IgE occurs exclusively at nasal level. METHODS We...
