botrytis cinerea is an important pathogen that causes diseases in ornamental crops. in presentresearch several greenhouses of roses located in central region of iran were surveyed toidentify the botrytis cinerea. a total of 80 isolates were collected from rose greenhouses incentral region of iran. morphological identification was based on characters such asconidiophore and conidial length. acco...
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...
based on the latest records of typhlops vermicularis merrem, 1820 from iran, this species is distributed in the northern and southern regions of the country. in this study, new records of typhlops vermicularis are presented and it is shown that distribution range of this species is extended towards the eastern and western iran, and according to the new distribution map, it can be assumed that t...
In this study molecular identification of four species of Gastropoda have been studied based on mitochondrial genes, COI and 16S rRNA in the present work for the first time in the northern rocky coastal zones of Persian Gulf during years 2013 and 2014. Planaxis sulcatus، Cerithidea cingulata، Siphonaria savignyi and Onchidium peronii Identified. After morphological identification, DNA extractio...
In this study, Dunaliella has been isolated in Jun. 2014 from Hoz-e Soltan and Aran-va-Bidgol salt Lakes (Iran). The isolates have been identified morphologically with the aid of simple light and invert microscope after isolation and purification on their specific medium (Moh202). By using molecular techniques such as polymerase chain reaction (PCR) and amplification of 18S rDNA gene primers, f...
introduction acetic acid bacteria are large group of obligate aerobic gram negative bacteria with the ability to oxidize ethanol to acetic acid (1). they are widely distributed in natural habitats and classified in family acetobacteraceae. members of this family are useful in industrial production of vinegar(2). acetic acid bacteria (aab) can use substrates as glucose, ethanol, lactate or glyc...
BACKGROUNDS: Gyrodactylus is a small monogenean ectoparasite that lives on the skin and fins of most of the world's fish species. Gyrodactylus appears to be one of the most prevalent parasites found in ornamental fish, especially in Cyprinids. Goldfish (Carassius auratus) are a popular ornamental fish that are highly contaminated by Gyrodcatylus. OBJECTIVES: The present study is aimed to identi...
چکیده: بررسی مقایسه ای گونه های مختلف مالاسزیا در پوست و گوش گوساله های نوزاد با مادرانشان با استفاده از روشهای مورفولوژیکی، بیوشیمیایی و فیزیولوژیکی مخمرهای لیپوفیلیک جنس مالاسزیا جزء فلور نرمال جلدی انسان و حیوانات می باشند که تحت شرایطی بیماریزا می شوند. از آنجایی که نه تنها گونه غیر وابسته به چربی بلکه سایر گونه های مالاسزیا از حیوانات مختلف جداسازی می شود لذا بررسی اپیدمیولوژی و انتشار ج...
Background: Aspergillus species are opportunistic pathogens among immunocompromised patients. In terms of pathogenesis and mycotoxin production, they are in great value. The aim of the this study was to evaluate of beta-tubulin gene for identification of clinical Aspergillus species by PCR-sequencing method compared to morphological features of clinical isolates (such as conidial shape in direc...
aphids are among important agricultural pests. the pest's evolutionary tendency towards a loss of taxonomically useful characteristics, as well as morphological plasticity due to host type and as a result of environmental factors, make a morphological identification of aphids difficult, whereas exact identification is indispensable for managment of these pests. thus, modern identification ...
