We assessed soil fungal diversity and community structure at two sampling times (t1 = 47 days and t2 = 104 days of plant age) in pots associated with four maize cultivars, including two genetically modified (GM) cultivars by high-throughput pyrosequencing of the 18S rRNA gene using DNA and RNA templates. We detected no significant differences in soil fungal diversity and community structure ass...

BACKGROUND AND OBJECTIVES Fungal endophthalmitis is a devastating form of ocular infection and postoperative endophthalmitis following cataract surgery is the commonest form of such infection. Early diagnosis is very important for effective management of these patients. As conventional techniques take longer time and lacks sensitivity, polymerase chain reaction (PCR) for detection of fungal DNA...

OBJECTIVES/HYPOTHESIS The role of fungi in chronic rhinosinusitis (CRS) is still controversial. The present study was conducted to detect and identify fungal species from the nasal polyp tissues of eosinophilic and noneosinophilic CRS, and to determine the role of fungal antigens in cytokine production. STUDY DESIGN Prospective study. METHODS Thirty-five specimens of nasal polyps were colle...

purpose: to compare the value of conventional laboratory methods and polymerase chain reaction (pcr) in the diagnosis of fungal keratitis. methods: this cross sectional study was conducted at khalili hospital, shiraz, iran. samples were taken from thirty-eight patients with findings suspicious for fungal keratitis. corneal scrapings were used for gram, giemsa and koh stains, culture and pcr ana...

DNA isolation is a crucial step of conducting genetic studies in any organism. However, this process is quite difficult when studying fungi because of the need to damage the fungal cell walls of specific structures. In this study, we developed a method for the rapid and efficient isolation of fungal DNA based on simultaneous mechanical and enzymatic cell wall degradation. There are several typi...

The demand for bioenergy caused an increased use of logging residues, branches and treetops that were previously left on the ground after harvesting. Residues are stored outdoors in piles and it is unclear to what extent fungi transform this material. Our objective was to quantify the amount of wood degrading fungi during storage using quantitative real-time PCR (qPCR) to detect basidiomycetous...

Nucleic acid amplification techniques permitting sensitive and rapid screening in patients at risk for invasive fungal infections are an important addition to conventional fungal diagnostic methods. However, contamination with fungal DNA may be a serious threat to the validity of fungal amplification-based assays. Besides rigorous handling procedures to avoid false-positive test results from ex...

The aim of this study was to compare the efficiency of DNA extraction from water as well as from blood samples spiked with A. fumigatus spores, using selected commercial kits. Extraction of DNA according to manufacturer's protocols was preceded by blood cells lysis and disruption of fungal cells by enzymatic digestion or bead beating. The efficiency of DNA extraction was measured by PCR using A...
