BioNumerics
BioNumerics is a bioinformatics desktop software application that manages microbiological data. It is developed by Applied Maths NV, a bioMérieux company. History BioNumerics was first released in 1998. PulseNet, a network run by the Centers for Disease Control and Prevention (CDC), uses BioNumerics to compare pulsed field gel electrophoresis (PFGE) patterns and whole genome sequences from different bacterial strains. CaliciNet, an outbreak surveillance network for noroviruses, is another example of a network which uses BioNumerics to submit norovirus sequences and basic epidemiologic information to a central database. Features The basis of BioNumerics is a database consisting of entries. The entries correspond to the individual organisms or samples under study and are characterized by a unique key and by a number of user-defined information fields. Each entry in a database may be characterized by one or more experiments that can be linked easily ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Applied Maths
Applied Maths NV, a bioMérieux company headquartered in Sint-Martens-Latem, Belgium, is a bioinformatics company developing software for the biosciences. History Applied Maths was founded in 1992 and gained worldwide recognition with the software GelCompar, used as a standard tool for the normalization and comparative analysis of electrophoresis patterns (PFGE, AFLP, RAPD, REP-PCR and variants, etc.). GelCompar II was released in 1998 to deal with the ever growing amounts of information following the success and expansion of electrophoresis and other fingerprinting techniques in various application fields in microbiology, virology and mycology. Following the introduction of the concepts of polyphasic taxonomy and the growing need to combine genotypic, phenotypic, electrophoresis and sequence information, Applied Maths released in 1996 the software package BIONUMERICS which still today is a platform for the management, storage and (statistical) analysis of all types of bi ...

Pulsed Field Gel Electrophoresis
Pulsed field gel electrophoresis is a technique used for the separation of large DNA molecules by applying to a gel matrix an electric field that periodically changes direction. Historical background Standard gel electrophoresis techniques for separation of DNA molecules provided huge advantages for molecular biology research. However, it was unable to separate very large molecules of DNA effectively. DNA molecules larger than 15–20 kb migrating through a gel will essentially move together in a size-independent manner. At Columbia University in 1984, David C. Schwartz and Charles Cantor developed a variation on the standard protocol by introducing an alternating voltage gradient to improve the resolution of larger molecules. This technique became known as pulsed-field gel electrophoresis (PFGE). The development of PFGE expanded the range of resolution for DNA fragments by as much as two orders of magnitude. Procedure The procedure for this technique is relatively similar to p ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Multilocus Sequence Typing
Multilocus sequence typing (MLST) is a technique in molecular biology for the typing of multiple loci, using DNA sequences of internal fragments of multiple housekeeping genes to characterize isolates of microbial species. The first MLST scheme to be developed was for ''Neisseria meningitidis'', the causative agent of meningococcal meningitis and septicaemia. Since its introduction for the research of evolutionary history, MLST has been used not only for human pathogens but also for plant pathogens. Principle MLST directly measures the DNA sequence variations in a set of housekeeping genes and characterizes strains by their unique allelic profiles. The principle of MLST is simple: the technique involves PCR amplification followed by DNA sequencing. Nucleotide differences between strains can be checked at a variable number of genes depending on the degree of discrimination desired. The workflow of MLST involves: 1) data collection, 2) data analysis and 3) multilocus sequence ana ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Amplified Fragment Length Polymorphism
AFLP-PCR or just AFLP is a PCR-based tool used in genetics research, DNA fingerprinting, and in the practice of genetic engineering. Developed in the early 1990s by KeyGene, AFLP uses restriction enzymes to digest genomic DNA, followed by ligation of adaptors to the sticky ends of the restriction fragments. A subset of the restriction fragments is then selected to be amplified. This selection is achieved by using primers complementary to the adaptor sequence, the restriction site sequence and a few nucleotides inside the restriction site fragments (as described in detail below). The amplified fragments are separated and visualized on denaturing on agarose gel electrophoresis , either through autoradiography or fluorescence methodologies, or via automated capillary sequencing instruments. Although AFLP should not be used as an acronym, it is commonly referred to as "Amplified fragment length polymorphism". However, the resulting data are not scored as length polymorphisms, but ...

Bioinformatics
Bioinformatics () is an interdisciplinary field that develops methods and software tools for understanding biological data, in particular when the data sets are large and complex. As an interdisciplinary field of science, bioinformatics combines biology, chemistry, physics, computer science, information engineering, mathematics and statistics to analyze and interpret the biological data. Bioinformatics has been used for '' in silico'' analyses of biological queries using computational and statistical techniques. Bioinformatics includes biological studies that use computer programming as part of their methodology, as well as specific analysis "pipelines" that are repeatedly used, particularly in the field of genomics. Common uses of bioinformatics include the identification of candidates genes and single nucleotide polymorphisms (SNPs). Often, such identification is made with the aim to better understand the genetic basis of disease, unique adaptations, desirable properties (e ...

Microbiology
Microbiology () is the scientific study of microorganisms, those being unicellular (single cell), multicellular (cell colony), or acellular (lacking cells). Microbiology encompasses numerous sub-disciplines including virology, bacteriology, protistology, mycology, immunology, and parasitology. Eukaryotic microorganisms possess membrane-bound organelles and include fungi and protists, whereas prokaryotic organisms—all of which are microorganisms—are conventionally classified as lacking membrane-bound organelles and include Bacteria and Archaea. Microbiologists traditionally relied on culture, staining, and microscopy. However, less than 1% of the microorganisms present in common environments can be cultured in isolation using current means. Microbiologists often rely on molecular biology tools such as DNA sequence based identification, for example the 16S rRNA gene sequence used for bacteria identification. Viruses have been variably classified as organisms, as they have ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Python (programming Language)
Python is a high-level, general-purpose programming language. Its design philosophy emphasizes code readability with the use of significant indentation. Python is dynamically-typed and garbage-collected. It supports multiple programming paradigms, including structured (particularly procedural), object-oriented and functional programming. It is often described as a "batteries included" language due to its comprehensive standard library. Guido van Rossum began working on Python in the late 1980s as a successor to the ABC programming language and first released it in 1991 as Python 0.9.0. Python 2.0 was released in 2000 and introduced new features such as list comprehensions, cycle-detecting garbage collection, reference counting, and Unicode support. Python 3.0, released in 2008, was a major revision that is not completely backward-compatible with earlier versions. Python 2 was discontinued with version 2.7.18 in 2020. Python consistently ranks as ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
