While DNA fingerprinting of M. tuberculosis isolates is being used increasingly in epidemiologic studies, the interpretation of fingerprint data is becoming increasingly complex, depending on the setting of the studies and the particular methods used for fingerprinting (4, 14). The present study was the first to investigate the implication of IS6110 clustering resulting from computerized RFLP analyses of isolates obtained from different geographic regions. This report provides an assessment of the standardized IS6110 fingerprinting method relative to other secondary fingerprinting methods and sets out information useful for studying the long-term clonal expansion and tracing of M. tuberculosis transmission in different settings, e.g., in a given geographic region and across geographic regions.. The establishment of an internationally standardized methodology for DNA fingerprinting of M. tuberculosis permits the analysis and comparison of DNA fingerprint patterns produced in many different ...

In forensic DNA profiling, the occurrence of complex mixed profiles is currently a common issue. Cases involving intimate swabs or skin flake tape liftings are prone to mixed profiles, because of more than one donor contributing to a DNA sample. By DNA profiling of single spermatozoa and skin flakes, problems associated with mixed profile could ideally be overcome. However, PCR is not a sensitive enough method to generate DNA profiles by STRs on single cells. Moreover, high quality intact DNA is required, but is not always available in skin flakes due to degradation. Additionally, single skin flakes are difficult to discriminate from other similar looking particles on tape liftings used to secure DNA samples from evidence. The main purpose of this study was to develop a method that enables DNA profiling of single sperm cells and skin flakes. After studying multiple whole genome amplification (WGA) protocols, REPLI-g Single Cell WGA was selected due to its suitability in the pre-amplification ...
The genetic identification consists to establish the unique and unforgeable DNA fingerprint of a dog, by analysing its DNA.. The DNA fingerprint is made of 22 genetic markers : 21 markers and 1 marker for gender. The genetic markers are coded in letters. The markers combinaison is different from a dog to another , even if they are related ( except true twins).. During parentage verifiation, ANTAGENE compares the DNA fingerprint of the father, the mother and the puppy. The compatible DNA fingerprints betwwen the puppy and the declared parents certify the lineage and brings a DNA certification of the parentage..

The ISAG 2006 norm is recognised by the FCI (Fédération Cynologique Internationale) and used by almost all Laboratories in Europe.. ANTAGENE is a member of ISAG and scored 100% in the ...
Quelle: Annals of Improbable Research 1(5): 26-27 (1995). by Mark Benecke. Zoologisches Institut der Universitaet, Koeln, Germany. We developed a method to obtain fingerprint patterns of microscopic animals which have neither arms nor fingers. Two species are discussed here.. The Usefulness of Fingerprinting. Fingerless organisms can be as deadly as any human criminal. When loosed upona law-abiding public, they have been known to cause malaria and other tropical diseases. Criminologists have good reason to identify and catch the individual organisms responsible for such crimes. We often hear and read about criminal cases being solved by fingerprints. Nowadays, so-called "genetic fingerprints" are also used, especially in forensic medicine. The classical and the genetic fingerprinting methods are both powerful but limited. !t is hard to carry out the classical fingerprint technique in organisms without fingers, and the genetic method is quite expensive. Our method is cheap and simple.. How we do ...
Each individual inherits two alleles of each STR marker, one from their mother and one from their father. If the two alleles are the same, the individual is homozygous for that particular marker and only one band will appear on the gel. If two different bands appear on the gel, then the individual has inherited two different alleles for that marker and is heterozygous. The gel electrophoresis images you have been examining represent four genetic markers, which could result in a maximum of eight bands (at most two for each marker) on a gel. The pattern of bands is the individuals genetic profile, or DNA fingerprint.. The more markers used to build the profile, the less likely it is that two individuals will have the same profile by chance. (You will learn why in the "Frequency Primer.") This means that if two samples have exactly the same profile, its almost certain that they are from the same individual! Typically, to positively identify humans, scientists use 13 markers; to identify ...

The retention of DNA samples is a second concern for privacy advocates. This is a real issue which should be addressed by maximizing protections of stored samples or by choosing to discard samples. Other concerns are aimed at the application of DNA databases in criminal prosecution. These criticisms exist regardless of the databases size/scope, but there is reason to believe that the increased attention to the caveats of DNA evidence that a universal database provides would improve these conditions. Along those lines, there are a number of benefits which come from universal coverage: ...

Brief Description: The HAPMAPPT05 plate of 91 individual samples, includes 46 Japanese in Tokyo and 45 Han Chinese in Beijing. In addition, there are 4 duplicated samples and 1 buffer control. The concentration of each DNA sample to be plated is normalized and then this concentration is verified. The DNA concentration is 250 ng/µl and there are 50 µg of DNA per well. Once all samples are in place, a DNA fingerprint is determined for each sample to verify the identity on the plate. The specific position on the plates has been optimized by NHGRI to reduce any possible errors in sample identity during the genotyping process. The positions of the 4 duplicated samples and 1 buffer control are indicated by gray shading. ...

Streptococcus thermophilus and Lactobacillus delbrueckii subsp. bulgaricus are involved in the manufacture of yogurt, and Bifidobacterium spp. can be supplemented if probiotic properties are expected. In such products, enumeration of each bacterial component is a hard task since they have similar nutritional requirements. For this reason, there is still no official and reliable methodology for this purpose. The objectives of the present study were to evaluate the most appropriate culture medium for the enumeration of four different Bifidobacterium species in the presence of S. thermophilus and L. delbrueckii subsp. bulgaricus isolated from commercial cultures and investigate the influence of different strains of S. thermophilus on the choice of medium. Among 11 isolates of S. thermophilus obtained from these cultures, and which were submitted to repetitive element sequence-based PCR (rep-PCR), nine were found to be distinct strains. For selective enumeration of the Bifidobacterium species, results
Summary Different PCR-based DNA fingerprinting techniques were evaluated for typing 26 clinical isolates belonging to the Acinetobacter calcoaceticus-A. baumannii complex. Seven isolates belonged to a previously defined outbreak while 19 isolates were unrelated epidemiologically. The PCR-based DNA fingerprinting techniques used were: (i) repetitive extragenic palindromic (REP) PCR; (ii) enterobacterial repetitive intergenic consensus (ERIC) PCR; (iii) randomly amplified polymorphic DNA with M13 forward primer; (iv) restriction analysis of the amplified 16S rRNA gene (ARDRA-16S); and (v) restriction analysis of an amplified region containing the 16S-23S rRNA spacer region and part of the 23S rRNA gene (ARDRA 23S + spacer). The discrimination index for the PCR-based DNA fingerprinting techniques was: 0.99 for REP; 0.94 for ERIC; 0.87 for M13; 0.60 for ARDRA-16S digested with Hpa II and |0.50 for ARDRA 23S + spacer. It was concluded that REP-PCR possessed high discriminatory power and reproducibility in

Interpretive Summary: Abstract - no summary required Technical Abstract: Bacillus mojavensis, RRC101 is an endophytic bacterium patented for control of fungal diseases in maize and other plants. DNA fingerprint analysis of the rep-PCR fragments of 35 B. mojavensis and 4 B. subtilis strains using the Diversilab genotyping system revealed genotypic distinctive strains along geographical origins. Culture extracts from these strains, RRC 101 were antagonistic to the pathogenic and mycotoxic fungus, Fusarium verticillioides. The identity of the inhibitory substance was recently determined to be the biosurfactant, surfactin. The absolute structure of this cyclic lipopeptide was determined from collisional ion dissociation (CID) analysis to be a cyclic heptapeptide linked to a ß-hydroxy fatty acid. Further, CID ...

The researchers, from the University of Cambridge and Addenbrookes Hospital in Cambridge, found unique molecular fingerprints for 11 types of childrens tumors, which could be used to develop blood tests to diagnose these cancers.. This may eventually lead to a quicker, more accurate way to diagnose tumors, and could also reduce the need for children to undergo surgery to get a diagnosis one day.. The research was funded by Sparks, the childrens medical research charity, and Cancer Research UK.. Each year almost 1,600 children are diagnosed with cancer in the UK. These cancers tend to behave differently to cancers in adults and therefore require different treatments.. The researchers uncovered the fingerprints left by the tumors by analyzing blood samples from children when they were diagnosed with cancer. They were looking for molecules that turn genes on and off, called microRNAs, to find common changes linked to different tumors.. In particular they found a very specific fingerprint which ...
Background:. Pseudomonas aeruginosa (PA) is a leading pathogen in intensive care units (ICUs). Surveillance for PA may improve empiric antimicrobial therapy, since colonizing strains may subsequently cause infections. The source of colonization may be endogenous or exogenous (from the environment or other patients). The PA source determines the measures needed for infection control. In this prospective study we aimed to investigate the sources of PA and to correlate colonizing and infecting strains. Methods:. ICU patients were screened on admission and weekly from the pharynx, endotracheal aspirate (EA), rectum and urine. Molecular typing of screening and clinical cultures isolates was performed using Enterobacterial Repetitive Intergenic Consensus (ERIC)-PCR. Results:. Between Nov2014-Jan2015, 34 patients were included in the study. Thirteen (38%) were colonized with PA upon admission. The rectum was the most common site for PA colonization (identifying 77% of the colonized patients upon ...
Dispersal is often associated with what we refer to as emigration and immigration. That is, movement from one population to another population. It is usually (not always) unidirectional. Knowing the dynamics of moose population dispersal, especially of the level of genetic exchange between different populations is also important for moose management. Since moose harvests typically set different bag-limits according to sex, identifying the sex cohort and the direction which gene flow occurs among adjacent populations can assist in developing responsible sex-biased management which assure animal numbers are kept at levels which maintain a high level of dispersal. It can also lead to the implementation of protected corridors between populations to help increase genetic exchange. This is very important for the rehabilitation of moose populations experiencing low recovery rates located adjacent to moose populations of sustainable size ...

The cell is the fundamental unit of all living organisms. Hence, in order to understand essential biological processes and the perturbations that give rise to disease, one must first dissect the functions of cells and the mechanisms that regulate them. Modern high-throughput protein and nucleic-acid sequencing techniques have become an indispensable component of this endeavor. In particular, single-cell RNA sequencing (scRNA-seq) permits one to determine the levels of RNA molecules - the gene copies - that are expressed in a given cell, and several versions of the methodology have been described in recent years. The spectrum of genes expressed in a given cell amounts to a molecular fingerprint, which yields a detailed picture of its current functional state. "For this reason, the technology has become an extraordinarily valuable tool, not only for basic research but also for the development of new approaches to treat diseases," says LMU biologist Wolfgang Enard. Enard and his team have now ...

A fingerprint sensor in accordance with the invention includes a non-conductive substrate providing a first surface onto which a user can apply a fingerprint to be sensed. A sensor circuit is applied to a second surface of the non-conductive substrate opposite the first surface to sense a fingerprint when juxtaposed proximally thereto. An electrostatic discharge conductor is applied to the non-conductive surface and is located between an area where a fingerprint is swiped and the sensor circuit. The electrostatic discharge conductor discharges electrostatic charge resulting from a user swiping a fingerprint across the first surface.
