objective(s): the nosocomial infections by aspergillus species are associated with constructions and increased dust loads in hospital indoors. our main object was to find the environmental sources of aspergillus species causing hospital acquired infections. materials and methods: the clinical and environmental samplings were performed during 18 months from spring 2010 to summer 2011 in imam edu...

some fungal species were isolated from scab or scab-like symptoms on leaves of various plant hosts in iran. some of them isolated from apple and pear leaves were investigated in the present study. the isolates were identified based on the morphological and cultural characteristics. on the other hand, for molecular identification and phylogenetic analyses were carried out based on the sequence o...

desert truffles, hypogeous pezizales (ascomycota), are difficult to identify due to evolutionary convergence of morphological characters among taxa that share a similar habitat and mode of spore dispersal. in this paper we document the presence of picoa lefebvrei (pat.) maire (=phaeangium lefebvrei) in iran and use phylogenetic analysis of the its and 28s rdna to show that this species belongs ...

aspergillus spp. are ubiquitous saprophytic fungi that cause a variety of diseases, ranging from hypersensitivity reactions to flulike pneumonia and life-threatening invasive aspergillosis. as the lung is the primary site of initial infection with airborne conidia, we investigated the innate immune responses of bronchial epithelial cells against different forms of aspergillus spp.

the genus phaeoacremonium is associated with decline disease of woody plants and with human infections. members of this genus have broad host range and wide geographical distribution. during 2010, ten isolates of phaeoacremonium were recovered from vascular tissues of persimmon (diospyros kaki) trees, showing decline symptoms in shiraz city. anamorphic characteristics such as, conidiophore morp...

The Phomopsis is a genus of imperfect plant pathogenic fungus whose hosts comprise several species in different regions of the world, such as grapes, soybean, acacia, hollyhock, velvetleaf, and several other plants. In this study, samples collected from hollyhock, velvetleaf, purple bauhinia, and acacia plants suspected to be infected with Phomopsis fungi. Samples were culture...

objective :cryptosporidiosis is one of the most important parasitic infections in iran which causes diarrhea in humans and animals. the identification of the cryptosporidium species among humans is necessary. this study aims to identify species of cryptosporidium isolated from patients that referred to three hospitals in tehran based on the 18s rrna gene by nested pcr-rflp assay. ‎methods :in t...

polymerase chain reaction and restriction fragment length polymorphism (pcr-rflp) and phylogenetic analysis were used for molecular identification of lactic acid bacteria (labs) isolated from apis mellifera. eighteen honeybee workers were collected from three different apiaries in west azerbaijan. labs from the gut of honeybees were isolated and cultured using routine biochemical procedures. ge...
