Polytomy identification in microbial phylogenetic reconstruction [PDF]

BMC Systems Biology, 2011
Abstract Background A phylogenetic tree, showing ancestral relations among organisms, is commonly represented as a rooted tree with sets of bifurcating branches (dichotomies) for simplicity, although polytomies (multifurcating branches) may reflect more accurate evolutionary relationships.

Microfluidic-Based Amplification-Free Bacterial DNA Detection by Dielectrophoretic Concentration and Fluorescent Resonance Energy Transfer Assisted in Situ Hybridization (FRET-ISH)

Biosensors, 2012
Although real-time PCR (RT-PCR) has become a diagnostic standard for rapid identification of bacterial species, typical methods remain time-intensive due to sample preparation and amplification cycle times.

Improved microbial gene identification with GLIMMER [PDF]

Nucleic Acids Research, 1999
The GLIMMER system for microbial gene identification finds approximately 97-98% of all genes in a genome when compared with published annotation. This paper reports on two new results: (i) significant technical improvements to GLIMMER that improve its accuracy still further, and (ii) a comprehensive evaluation that demonstrates that the accuracy of the

Zinc removal from highly acidic and sulfate-rich wastewater in horizontal sub-surface constructed wetland

Water Science and Technology, 2021
This study demonstrated the successful use of a laboratory-scale baffled horizontal constructed wetland substituted with mixed organic media for zinc removal from high acidity (∼610 mg L−1 as CaCO3), sulfate-rich (∼1,300 mg L−1) wastewater.

Comparison of automatic methods MALDI-TOF, VITEK2 and manual methods for the identification of intestinal microbial communities on the example of samples from alpacas (Vicugna pacos)

Journal of Veterinary Research, 2023
Universally, in microbiological diagnostics the detection of live bacteria is essential. Rapid identification of pathogens enables appropriate remedial measures to be taken. The identification of many bacteria simultaneously facilitates the determination

Metagenomic Sequencing of Positive Blood Culture Fluid for Accurate Bacterial and Fungal Species Identification: A Pilot Study

Microorganisms, 2023
With blood stream infections (BSIs) representing a major cause of mortality and morbidity worldwide, blood cultures play a crucial role in diagnosis, but their clinical application is dampened by the long turn-around time and the detection of only ...

Microbial Identification

, 2023
For microbial identification, the standard method is to perform comparative gene sequence analysis on rDNA, especially the 16S rRNA gene of bacteria or the ITS of fungi. The comparative gene sequence analysis of rDNA has been proved to have the highest precision microbial identification system technology.
