BACKGROUND Within the root endosphere, fungi are known to be important for plant nutrition and resistance to stresses. However, description and understanding of the rules governing community assembly in the fungal fraction of the plant microbiome remains scarce. METHODS We used an innovative DNA- and RNA-based analysis of co-extracted nucleic acids to reveal the complexity of the fungal commu...

BACKGROUND The signs and symptoms associated with fungal meningitis are similar to those seen with more common bacterial infections. In this study, we investigate whether Aspergillus or Candida DNA can be detected in cerebrospinal fluid (CSF) samples from patients suspected of fungal meningitis using real-time PCR assay. METHODS From April 2007 to November 2009, we evaluated CSF samples and s...

Like bacteria, fungi play an important role in the soil ecosystem. As only a small fraction of the fungi present in soil can be cultured, conventional microbiological techniques yield only limited information on the composition and dynamics of fungal communities in soil. DNA-based methods do not depend on the culturability of microorganisms, and therefore they offer an attractive alternative fo...

We examined the effect of different soil sample sizes obtained from an agricultural field, under a single cropping system uniform in soil properties and aboveground crop responses, on bacterial and fungal community structure and microbial diversity indices. DNA extracted from soil sample sizes of 0.25, 1, 5, and 10 g using MoBIO kits and from 10 and 100 g sizes using a bead-beating method (SARD...

PURPOSE To compare polymerase chain reaction (PCR) to microbial culture for the detection and identification of bacterial and fungal pathogens in microbial keratitis. DESIGN Prospective cohort study. METHODS A total of 108 consecutive corneal ulcers were cultured and analyzed by PCR using pan-bacterial and pan-fungal primers. PCR products were cloned, sequenced, and compared to culture resu...

Next generation fungal amplicon sequencing is being used with increasing frequency to study fungal diversity in various ecosystems; however, the influence of sample preparation on the characterization of fungal community is poorly understood. We investigated the effects of four procedural modifications to library preparation for high-throughput sequencing (HTS). The following treatments were co...

We studied the effects of Fusarium oxysporum f.sp. strigae (Fos), a soil-borne biocontrol agent (BCA) against Striga hermonthica, on total fungal and arbuscular mycorrhizal fungal (AMF) taxa in rhizospheres of maize in both clayey and sandy soil. Effects of Fos-BCA 'Foxy-2' were evaluated against (1) S. hermonthica presence, and (2) organic fertilization with Tithonia diversifolia residues at 1...

Rapid non-culture-dependent assays for identification of fungi quicken diagnosis and prompt treatment of invasive fungal disease. Fungal DNA extracts from pure cultures of the most frequently isolated fungal pathogens belonging to the Genera Aspergillus, Candida and Cryptococcus along with less common pathogenic Genera were amplified with the general fungal primer pair internal transcribed spac...
