Phytoplankton cells and resting cysts of the species Scrippsiella trochoidea are regular and dominant components of the dinoflagellate flora of coastal marine waters and sediments around the world. This species is a common harmful bloom forming species in coastal waters. In this study, for the first time cyst of S. trochoidea were isolated from the sediments of southeast coast of Iran. Five str...

background: acanthamoeba spp. is the causative agent of blindness keratitis and fatal encephalaitis. presence of acanthamoeba spp. in a wide variety of niches such as different water types can lead to exposure of high risk people such as contact lens wearers. the main aim of the present study was to explore the occurrence of acanthamoeba genotypes in the recreational water sources using both mo...

Species of Phyllosticta are important group of pathogenic and endophytic fungi that are reported from various crop plants, ornamental and non-fruiting plants. These fungi cause several diseases such as leaf and fruit spots and fruit rot. In order to identify Phyllosticta species in Guilan province, several collections were examined around the region. Altogether 14 taxa were isolated from differ...

In bryophytes a morphological species concept is still most commonly employed, but delimitation of closely related species based on morphological characters is often difficult. Here we test morphological species circumscriptions in a species complex of the moss genus Racomitrium, the R. canescens complex, based on variable DNA sequence markers from the plastid (rps4-trnT-trnL region) and nuclea...

Background and Objective: Salmonellosis is an important infectious zoonotic disease that makes it even more significant to identify and control the causative strains. Molecular methods, especially polymerase chain reaction (PCR), for virulence genes can help to quickly and accurately identify Salmonella strains. Accordingly, the purpose of this study was molecular identification based on sivH, ...

opportunistic fungal infections including candidiasis have increased dramatically in recent years. most medically important fungi are candida species. rapid identification od candida isolates to the species level in the clinical laboratory is necessary for more rapid and effective antifungal therapy and to facilitate hospital infection control measures. conventional morphological methods for id...
