Chronic granulomatous disease (CGD) is characterized by a defect in phagocytic cells that lead to recurrent bacterial and fungal infections. The etiology of most common fungal infections in CGD are Aspergillus species. Aspergillus nidulans is one of several species of Aspergillus with low pathogenicity. However, it was reported to cause fatal invasive Aspergillosis in patients with CGD. Here we...

Background and Aim:  PCR has high sensitivity and specificity for the determination offungal DNA. It is also useful for rapid identification of the most common species of Aspergillus. The purpose of this study was to compare culture method with nested PCR method to determine Aspergillesion in diabetic foot patient in Imam Khomeini Hospital, Tehran. Material and Methods: Sixty-five case...

Aspergillus section Restricti together with sister section Aspergillus (formerly Eurotium) comprises xerophilic species, that are able to grow on substrates with low water activity and in extreme environments. We adressed the monophyly of both sections within subgenus Aspergillus and applied a multidisciplinary approach for definition of species boundaries in sect. Restricti. The monophyly of s...

A novel species, Aspergillus brasiliensis sp. nov., is described within Aspergillus section Nigri. This species can be distinguished from other black aspergilli based on intergenic transcribed region, beta-tubulin and calmodulin gene sequences, by amplified fragment length polymorphism analysis and by extrolite profiles. A. brasiliensis isolates produced naphtho-gamma-pyrones, tensidol A and B ...

OBJECTIVES Invasive aspergillosis (IA) caused by Aspergillus terreus is a significant cause of morbidity and mortality in patients with haematological malignancy (HM). Very few data are available in this patient population to differentiate IA patients with A. terreus from those with non-terreus species of Aspergillus to compare outcomes. We retrospectively investigated 513 HM patients who were ...

Aflatoxins are the most serious problem in production and export of pistachio of Iran. They are amongst the most toxic mycotoxins and are produced predominantly by Aspergillus flavus and A. parasiticus. Pistachio is susceptible to invasion by aflatoxigenic Aspergillus species and subsequent production of aflatoxins, during preharvesting, processing, transportation or storage. Various methods ha...

Four new species, Aspergillus eucalypticola, A. neoniger, A. fijiensis and A. indologenus are described and illustrated. Aspergillus eucalypticola was isolated from Eucalyptus leaf from Australia, and is related to A. tubingensis and A. costaricaensis, but could clearly be distinguished from them based on either β-tubulin or calmodulin sequence data. Aspergillus eucalypticola produced pyranonig...

Background and Purpose: Keratinophilic fungi are among the important groups of fungi living in the soil. This study aimed to isolate and identify keratinophilic fungi from the soil of three Iranian islands, namely Greater Tunb, Abu Musa, and Sirri, located in the Persian Gulf using morphological and molecular (polymerase chain reaction) methods. Materials and Methods: In this study, a total ...

BACKGROUND AND PURPOSE Pistacia atlantica, which belongs to the Anacardiaceae family, grows in the Zagrossian region of Iran. The aim of this study was to evaluate the antifungal properties of Pistacia atlantica and olive leaf extracts against different fungal species. MATERIALS AND METHODS In this study, we assessed the activities of olive leaf extracts and Pistacia atlantica leaf and fruit ...
