Fungi produce a wide range of secondary metabolites such as antibiotics, toxins, alkaloids, fatty acids, ketones and alcohols during active cell growth. The present study was aimed to identify secondary metabolites from some Penicillium species, using GC-MS. Many important compounds such as 3-oxoquinuclidine in Penicillium jenseii, formamidine in Penicillium pusillum, orcinol and 1,3,8-p-mentha...

Background: Isfahan is one of the major foci of cutaneous leishmaniasis in Iran. According to the epidemiological studies, both urban and rural forms have been reported in Isfahan. Accurate identification and characterization of Leishmania is essential for the control of the disease. Several different molecular techniques for Leishmania identification are developed including use of monoclonal a...

sphecidae is a large and important family of hymenoptera. all members of this family are presocial predators of other arthropods and play a role in the control of pest complex. in this study, sphecids were collected from east azerbaijan province using sweep net, malaise traps and yellow pan traps. twenty species of the family sphecidae (hymenoptera), belonging to subfamilies pemphredoninae, ast...

pythium species are cosmopolitan, fungus-like oomycotes which may cause diseases in plants, animals and even human beings. some of the species, however, are saprophytes and also well-proven biological control agents of plant pathogenic fungi. since 1968, when the first pythium species was reported from iran, ca 44 species, two varieties, and five groups of this genus have been reported from dif...

aims: a very common species of leeches has been named as hirudo medicinalis. regarding to the application of leeches in medicine and their fast extinction, this study was performed in aquatic habitats of kashan aimed to determine the distribution of leeches and to provide information about their regional and habitat characteristics. materials & methods: this descriptive study was conducted duri...

background: non- tuberculous mycobacteria are environmental opportunistic pathogens that can be found in various terrestrial and aquatic habitats. there are an epidemiological links between species isolated in tap water and those isolated from patients. hsp65 gene has more variability in its sequences, compared to the some more conserved genes in ntm, for identification of mycobacteria to speci...

Background: Cutaneous Leishmaniasis, is endemically observed in different parts of Iran in two forms of anthroponotic and zoonotic. The identification of both species and the type of disease are beneficial for treatment and prevention. Microscopic identification of Leishmania species has not provided promising efficacy. The aim of this study was to determine the Le...

In the framework of the collection and identification of agaric fungi of Iran, three species of the genus Lepiota, viz. Lepiota brunneoincarnata, L. echinella and L. subincarnata are reported as new records for mycobiota of Iran. Two species, L. brunneoincarnata and L. subincarnata are deadly poisonous taxa. Up to now, two species of Amanita, A. phalloides and A. verna, and one from Galerina, G...
