Tuberculosis outbreaks in prison housing units for HIV-infected inmates--California, 1995-1996. (1/3442)

During 1995-1996, staff from the California departments of corrections and health services and local health departments investigated two outbreaks of drug-susceptible tuberculosis (TB). The outbreaks occurred in two state correctional institutions with dedicated HIV housing units. In each outbreak, all cases were linked by IS6110-based DNA fingerprinting of Mycobacterium tuberculosis isolates. This report describes the investigations of both outbreaks; the findings indicated that M. tuberculosis can spread rapidly among HIV-infected inmates and be transmitted to their visitors and prison employees, with secondary spread to the community.  (+info)

Influence of sampling on estimates of clustering and recent transmission of Mycobacterium tuberculosis derived from DNA fingerprinting techniques. (2/3442)

The availability of DNA fingerprinting techniques for Mycobacterium tuberculosis has led to attempts to estimate the extent of recent transmission in populations, using the assumption that groups of tuberculosis patients with identical isolates ("clusters") are likely to reflect recently acquired infections. It is never possible to include all cases of tuberculosis in a given population in a study, and the proportion of isolates found to be clustered will depend on the completeness of the sampling. Using stochastic simulation models based on real and hypothetical populations, the authors demonstrate the influence of incomplete sampling on the estimates of clustering obtained. The results show that as the sampling fraction increases, the proportion of isolates identified as clustered also increases and the variance of the estimated proportion clustered decreases. Cluster size is also important: the underestimation of clustering for any given sampling fraction is greater, and the variability in the results obtained is larger, for populations with small clusters than for those with the same number of individuals arranged in large clusters. A considerable amount of caution should be used in interpreting the results of studies on clustering of M. tuberculosis isolates, particularly when sampling fractions are small.  (+info)

Evaluation of pulsed-field gel electrophoresis of genomic restriction fragments in the discrimination of Yersinia enterocolitica O:3. (3/3442)

One hundred and six Yersinia enterocolitica serogroup O:3, biotype 4 isolated from human and porcine samples in 1984 and in the years 1993 5 were examined by pulsed-field gel electrophoresis (PFGE). The genomic profiles produced by the enzymes NotI and XbaI were studied. Sixteen (A-P) and 8 (1-8) different pulsotypes were obtained, respectively. By combining the pulsotypes produced by both NotI and XbaI 24 different types were distinguished. The two major types, designated as A1 and B1, comprised 36% of all strains tested. The proportions of pulsotypes A1 and B1 were, 35.9 and 25.6%, respectively, among strains isolated in 1984. The corresponding figures among the strains isolated in 1993-5 were 35.8 and 41.8%. Nine pulsotypes were found only in 1984 and nine only in 1993-5. The proportions of the major pulsotypes, A1 and B1, in human isolates were 42.9 and 35.7% and in porcine isolates 22.2 and 36.1% respectively. Six types were found among both human and porcine isolates, 8 only among human strains and 10 only among porcine strains.  (+info)

Effect of phenylurea herbicides on soil microbial communities estimated by analysis of 16S rRNA gene fingerprints and community-level physiological profiles. (4/3442)

The effect of three phenyl urea herbicides (diuron, linuron, and chlorotoluron) on soil microbial communities was studied by using soil samples with a 10-year history of treatment. Denaturing gradient gel electrophoresis (DGGE) was used for the analysis of 16S rRNA genes (16S rDNA). The degree of similarity between the 16S rDNA profiles of the communities was quantified by numerically analysing the DGGE band patterns. Similarity dendrograms showed that the microbial community structures of the herbicide-treated and nontreated soils were significantly different. Moreover, the bacterial diversity seemed to decrease in soils treated with urea herbicides, and sequence determination of several DGGE fragments showed that the most affected species in the soils treated with diuron and linuron belonged to an uncultivated bacterial group. As well as the 16S rDNA fingerprints, the substrate utilization patterns of the microbial communities were compared. Principal-component analysis performed on BIOLOG data showed that the functional abilities of the soil microbial communities were altered by the application of the herbicides. In addition, enrichment cultures of the different soils in medium with the urea herbicides as the sole carbon and nitrogen source showed that there was no difference between treated and nontreated soil in the rate of transformation of diuron and chlorotoluron but that there was a strong difference in the case of linuron. In the enrichment cultures with linuron-treated soil, linuron disappeared completely after 1 week whereas no significant transformation was observed in cultures inoculated with nontreated soil even after 4 weeks. In conclusion, this study showed that both the structure and metabolic potential of soil microbial communities were clearly affected by a long-term application of urea herbicides.  (+info)

Arbitrarily primed PCR to type Vibrio spp. pathogenic for shrimp. (5/3442)

A molecular typing study on Vibrio strains implicated in shrimp disease outbreaks in New Caledonia and Japan was conducted by using AP-PCR (arbitrarily primed PCR). It allowed rapid identification of isolates at the genospecies level and studies of infraspecific population structures of epidemiological interest. Clusters identified within the species Vibrio penaeicida were related to their area of origin, allowing discrimination between Japanese and New Caledonian isolates, as well as between those from two different bays in New Caledonia separated by only 50 km. Other subclusters of New Caledonian V. penaeicida isolates could be identified, but it was not possible to link those differences to accurate epidemiological features. This contribution of AP-PCR to the study of vibriosis in penaeid shrimps demonstrates its high discriminating power and the relevance of the epidemiological information provided. This approach would contribute to better knowledge of the ecology of Vibrio spp. and their implication in shrimp disease in aquaculture.  (+info)

Organization of the gene cluster for biosynthesis of penicillin in Penicillium nalgiovense and antibiotic production in cured dry sausages. (6/3442)

Several fungal isolates obtained from two cured meat products from Spain were identified as Penicillium nalgiovense by their morphological features and by DNA fingerprinting. All P. nalgiovense isolates showed antibiotic activity in agar diffusion assays, and their penicillin production in liquid complex medium ranged from 6 to 38 microgram. ml-1. We constructed a restriction map of the penicillin gene cluster of P. nalgiovense and found that the organization of the penicillin biosynthetic genes (pcbAB, pcbC, and penDE) is the same as in Penicillium chrysogenum and Aspergillus nidulans. The pcbAB gene is located in an orientation opposite that of the pcbC and penDE genes in all three species. Significant amounts of penicillin were found in situ in the casing and the outer layer of salami meat during early stages of the curing process, coinciding with fungal colonization, but no penicillin was detected in the cured salami. The antibiotic produced in situ was sensitive to penicillinase.  (+info)

Identification of Epichloe endophytes in planta by a microsatellite-based PCR fingerprinting assay with automated analysis. (7/3442)

Epichloe endophytes are a group of filamentous fungi that include both sexual (Epichloe) and asexual (Neotyphodium) species. As a group they are genetically diverse and form both antagonistic and mutualistic associations with temperate grasses. We report here on the development of a microsatellite-based PCR system for fingerprinting this group of fungi with template isolated from either culture or infected plant material. M13mp19 partial genomic libraries were constructed for size-fractionated genomic DNA from two endophyte strains. These libraries were screened with a mixture of DIG-labeled dinucleotide and trinucleotide repeat probes. Positive clones were sequenced, and nine unique microsatellite loci were identified. An additional microsatellite was serendipitously identified in the 3' untranscribed region of the 3-hydroxy-3-methylglutaryl coenzyme A (HMG CoA) reductase gene from N. lolii Lp19. Primers were designed for each locus and a panel of endophytes, from different taxonomic groupings, was screened to determine the degree of polymorphism. On the basis of these results a multiplex assay was developed for strain identification with fluorescently labeled primers for five of these loci. Using this system the size of the products amplified can be precisely determined by automated analysis, and an allele profile for each strain can be readily generated. The assay was shown to resolve endophyte groupings to the level of known isozyme phenotype groupings. In a blind test the assay was used successfully to identify a set of endophytes in planta. A reference database of allele sizes has been established for the panel of endophytes examined, and this will be expanded as new strains are analyzed.  (+info)

A method for estimating nucleotide diversity from AFLP data. (8/3442)

A method for estimating the nucleotide diversity from AFLP data is developed by using the relationship between the number of nucleotide changes and the proportion of shared bands. The estimation equation is based on the assumption that GC-content is 0.5. Computer simulations, however, show that this method gives a reasonably accurate estimate even when GC-content deviates from 0.5, as long as the number of nucleotide changes per site (nucleotide diversity) is small. As an example, the nucleotide diversity of the wild yam, Dioscorea tokoro, was estimated. The estimated nucleotide diversity is 0.0055, which is larger than estimations from nucleotide sequence data for Adh and Pgi.  (+info)

Minisatellite DNA probes which can detect a large number of autosomal loci dispersed throughout the human genome were used to examine the constitutional and tumour DNA of 35 patients with a variety of cancers of which eight were of gastrointestinal origin. Somatic changes were seen in the tumour DNA in ten of the 35 cases. The changes included alterations in the relative intensities of hybridising DNA fragments, and, in three cases of cancers of gastrointestinal origin, the appearance of novel minisatellite fragments not seen in the corresponding constitutional DNA. The results of this preliminary study suggests that DNA fingerprint analysis provides a useful technique for identifying somatic changes in cancers.
Several recent studies have used proportions of tuberculosis cases sharing identical DNA fingerprint patterns (i.e., isolate clustering) to estimate the extent of disease attributable to recent transmission. Using a model of introduction and transmission of strains with different DNA fingerprint patterns, we show that the properties and interpretation of clustering statistics may differ substantially between settings. For some unindustrialized countries, where the annual risk for infection has changed little over time, 70% to 80% of all age groups may be clustered during a 3-year period, which underestimates the proportion of disease attributable to recent transmission. In contrast, for a typical industrialized setting (the Netherlands), clustering declines with increasing age (from 75% to 15% among young and old patients, respectively) and underestimates the extent of recent transmission only for young patients. We conclude that, in some settings, clustering is an unreliable indicator of the extent of

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 ...

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 ...

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

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 ...

  • Wellcome Genome Campus: "What is a DNA Fingerprint/What is gel electrophoresis? (
  • The teacher was able to take a sample of that blood and do some DNA analysis on it and came up with the results as shown in the far left well of the gel electrophoresis chamber. (
  • 4) To actually make a fingerprint of the DNA we must put all our fragments into a single well in a gel electrophoresis chamber. (
  • The DNA will be digested with a fixed set of restriction enzymes, separated on a gel by gel electrophoresis, and then analyzed for patterns of similarity with the crime scene sample. (
  • Perform agarose gel electrophoresis on DNA samples. (
  • 2. DNA is cut with restriction enzymes into fragments which are then separated into bands by electrophoresis on an agarose gel. (
  • The DNA pieces are sorted according to size by a sieving technique called electrophoresis. (
  • The great sensitivity and specificity of this multiplex (which is better than the available commercial kits) was presented on the Second European Symposium on Human Identification in June 1998 in Innsbruck ( DNA typing of fingerprints on skin debris: Sensitivity of Capillary Electrophoresis in forensic applications using multiplex PCR ). (
  • Running a gel electrophoresis is a cost-effective tool for DNA fingerprinting. (
  • In DNA fingerprinting, a gel electrophoresis can be done to separate the fragments. (

  • DNA fingerprinting is done by analyzing repeating patterns of base pairs in DNA sequences that are known to vary greatly among individuals. (
  • Restriction enzymes, also known as endonucleases, recognize specific sequences of DNA base pairs and cut, or chemically separate, DNA at that specific arrangement of base pairs. (
  • Bacterial cells protect their own DNA from being self-digested by modifying certain nitrogen bases along their genome, this prevents their restriction enzymes from recognizing and digesting their own sequences. (
  • In 1984, Alec Jefferys , a British scientist, found DNA sequences he called minisatellites that don't contribute to how the gene works but are repeated in the gene. (
  • Definition- a method of isolating and then making images of sequences of DNA. (
  • 4. A radioactive DNA probe is added which will bind to specific DNA sequences or minisatellites on the nylon membrane. (
  • Living organisms that look different or have different characteristics also have different DNA sequences. (
  • The more varied the organisms, the more varied the DNA sequences. (
  • DNA fingerprinting is a very quick way to compare the DNA sequences of any two living organisms. (
  • Each minisatellite is composed of DNA sequences of 2 to 9 pairs of bases like GGTTG, GGTTG, GGTTG, GGTTG, GGTTG which is a case repeated five times. (
  • Fluorophore-labeled oligonucleotide primers complementary to defined interspersed repetitive sequences conserved in diverse bacteria were used in the polymerase chain reaction to generate DNA fingerprint patterns from selected pathogenic bacteria. (
  • One Monday at 9:05 a.m., they produced the first genetic fingerprints, maps of sequences within the strands of DNA that varied from person to person. (
  • Dispersed repetitive DNA sequences have been described recently in eubacteria. (
  • Oligonucleotides matching Repetitive Extragenic Palindromic [REP] elements and Enterobacterial Repetitive Intergenic Consensus [ERIC] sequences were synthesized and tested as opposing PCR primers in the amplification of eubacterial genomic DNA. (
  • So the basic idea of RFLP is that you're using those restriction enzymes, specialized enzymes that cut DNA at highly specific sequences to cut up DNA into different lengths. (
  • STR sequences can also be directly sequenced using DNA sequencing machines, but this method has yet to move into mainstream usage and is used primarily within the research community. (
  • DNA fingerprinting is primarily concerned with the length of a DNA strand, whereas DNA profiling focuses on the relative positions of DNA sequences. (
  • The polymerase chain reaction, or PCR, is a powerful genetic technique that allows researchers to amplify DNA sequences of interest. (
  • A method used to identify multilocus DNA banding patterns that are specific to an individual by exposing a sample of the person's DNA to molecular probes and various analytical techniques such as Southern blot analysis. (
  • The ability to identify patterns within DNA that are unique to each individual - except identical twins, who share the same pattern - has been used to convict murderers and clear those wrongly accused, to identify the victims of war and settle paternity disputes. (
  • These band patterns provided unambiguous DNA fingerprints of different eubacterial species and strains. (
  • In some cases, the restriction patterns differed by only a few fragment bands, and two isolates differed only in the location of a single DNA fragment. (
  • Some clusters of patients who have Mycobacterium tuberculosis isolates with identical DNA fingerprint patterns grow faster than others. (
  • The capacity to differentiate Mycobacterium tuberculosis strain patterns by DNA fingerprinting has shown promise in tuberculosis (TB) control since this tool was first applied to outbreak investigations ( 1 - 3 ) and population-based studies ( 4 , 5 ) in the early 1990s. (
  • Thus, a large proportion of disease in older patients is attributable to reactivation of infections acquired many years ago, and, given the short half-life of DNA fingerprint patterns (5), only a small proportion of old patients share identical isolates with other patients. (
  • The laboratory databases included computerized images of DNA fingerprint patterns from all M. (
  • We conducted this study to determine the epidemiologic evidence of transmission among patients whose isolates have similar DNA fingerprint patterns (i.e., differing by a single band). (
  • Mycobacterium tuberculosis transmission between cluster members with similar fingerprint patterns. (
  • For their study, the research team took DNA samples from breast, colon, lung, thyroid and pancreas tumors, and from healthy tissue, and analyzed methylation patterns on the DNA. (
  • Most of the studies characterizing DNA methylation patterns have been restricted to particular genomic loci in a limited number of human samples and pathological conditions. (
  • The DNA methylation patterns revealed show this epigenetic mark to be critical in tissue-type definition and stemness, particularly around transcription start sites that are not within a CpG island. (
  • Thus, the DNA methylation patterns identified across the largest spectrum of samples, tissues, and diseases reported to date constitute a baseline for developing higher-resolution DNA methylation maps and provide important clues concerning the contribution of CpG methylation to tissue identity and its changes in the most prevalent human diseases. (
  • The sorted double-stranded DNA fragments were then subjected to a blotting technique in which they were split into single strands and transferred to a nylon sheet. (
  • The fragments underwent autoradiography in which they were exposed to DNA probes-pieces of synthetic DNA that were made radioactive and that bound to the minisatellites. (
  • 3) Next, take a pair of scissors (the enzyme) and cut the DNA into fragments along each of the lines. (
  • Because our DNA fragments are slightly polar (have an electric charge), they are carried with the current as it moves through the chamber. (
  • The longer fragments don't move as far (because they are heavier) and therefore, end up closer to where the DNA was loaded into the chamber. (
  • Evaluate who cannot be excluded from the investigation by constructing a standard curve and determining the size of the DNA fragments from the gel using Logger Pro . (
  • Hypothesis: If DNA samples are collected from different mother and fathers, then it can be determined which DNA samples have common genes fragments. (
  • Students load harmless predigested DNA samples onto agarose gels and separate the fragments to produce fingerprints. (
  • However, in some instances the DNA fragments can melt due to the current. (
  • We investigated the usefulness of a novel DNA fingerprinting technique, AFLP, which is based on the selective amplification of genomic restriction fragments by PCR, to differentiate bacterial strains at the subgeneric level. (
  • Depending on the genus, total genomic DNA of each bacterium was digested with a particular combination of two restriction endonucleases and the resulting fragments were ligated to restriction halfsite-specific adaptors. (
  • Well there's something about fragments and the lengths, now a restriction fragment is something that is created when a special kind of cutting enzyme called a restriction enzyme cuts the DNA poly is a root word that many of you know it means many, morph means shape or form and so a polymorphism means that you see different sizes or shapes in the length of people's DNA fragments. (
  • In the presence of specific DNA repair enzymes, DNA fragments will reanneal or stick themselves to other fragments with cut ends that are complimentary to their own end sequence. (
  • Following staining to locate the DNA, the gel is observed and the fragments appear as a pattern of bands. (
  • This amplification allows better and easier genetic characterization and can be used for a variety of tasks including those in the context of genetic disease diagnosis, maternity/paternity tests, DNA forensics, or simply in the production of large amounts of DNA fragments for further study. (
  • Ligase was all about dealing with those small Okazaki fragments, a result of only being able to open your helical DNA at very localized spots (with the helicase). (
  • The incidence of 121 HaeIII DNA fragments among 33 cell lines derived from unrelated individuals was used to estimate allelic and genotypic frequencies for each fragment and for composite individual DNA fingerprints. (
  • This technique involves the use of restriction fragment length polymorphisms (RFLP): fragments of DNA of differing molecular mass between individuals resulting from digestion of the genome by restriction enzymes. (
