introduction: nocardia is saprophytic soil bacterium of the actinomycetes families. nocardia has high diversity of species and due to species diversity of nocardia, phenotypic tests are essential for early identification of nocardia species. methods: 155 soil samples from different regions of north khorasan province in iran were collected, including: urban and rural areas. isolation of nocardia...
Amirmijani, A. M. 2019. Important characters in identification of Cladosporium spp. Plant Pathology Science 8(1):50-59. DOI: 10.2982/PPS.8.1.50. The genus Cladosporium is one of the largest genera of fungi. Its species live in different ways: as plant pathogens, as saprobes in the soil or on decaying plant materials, or as hyperparasitic on other fungi. Morphological characteristics of con...
Pleuronectiforme fishes of the Persian Gulf coastlines along Khuzestan, Bushehr and Hormozgan provinces were morphometrically and meristically studied from April 2003 to September 2005, in order to identify species. In this experiment, 1551 fish samples were caught by trawl or collected from fish markets. The sampling was carried out in 27 regions seasonally. Thirty six traits and parameters in...
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 ...
Introduction & Objective: Candida species can cause opportunistic infections in human. Although Candida albicans is major pathogenic species, non-albicans species of Candida such as C. glabrata , C. tropicalis and C. krusei have been increasingly reported. Identification of Candida species is essential for effective antifungal therapy and for infection control purposes. In the present study the...
background dermatophytes are a group of keratinophilic fungi worldwide, which can infect the skin, hair and nails of humans and animals. this genus includes several species that present different features of dermatophytosis. although, laboratory diagnosis of dermatophytes is based on direct microscopy, biochemical tests and culture, these manners are expensive, time consuming and need skilled s...
objective: fungal nail infection (onychomycosis) is a common disease in all communities consisting about 50 percent of nail disorders. yeasts are one of the important causative agents of onychomycosis. identification of the yeast species is important in the epidemiological and therapeutical point of views. the aim of the present study is the precise species identification of the pathogenic yeas...
background: classical bacteriological detection of brucella species from food, and environment is routinely carried out based on morphological and biochemical characteristics. however, for increasing specificity and sensitivity of species identification methods, development of a molecular assay is necessary that was main aim of this study. methods: panel of some reference strains belonging to t...
30 milled rice samples were collected from retailers in four states of Malaysia. These samples were evaluated for Eurotium spp. contaminations by direct plating on malt extract salt agar (MESA). All Eurotium were isolated and identified based on morphology and nucleotide sequences of internal transcribed spacer 1 (ITS1) and ITS2 of the rDNA. Four Eurotium species (E. rubrum, E. amstelodami, E....
