Ook de formule wordt een traditie: een plenair symposium op dinsdagochtend, dit jaar met als thema ‘Communication’, gevolgd door overwegend thematisch in- gedeelde parallelsessies. De multidisciplinaire, interactieve sessie van vorig jaar was dermate succesvol, dat deze sessievorm dit voorjaar wordt verdubbeld: één over mycobacteriële infecties bij kinderen en de ander over Chlamydia trachomatis en infertiliteit. AIO’s blijven zeer welkom op de Voorjaarsvergadering: zij worden vrijgesteld van inschrijfkosten, mid- dels de ‘Young Investigators Grant’, op voorwaarde dat zij een presentatie houden. Uiteraard is alleen de presenterende auteur van een voordracht of poster vrijgesteld. ‘Communication’ is het onderwerp van het plenaire symposium op dinsdagochtend: communicatie tus- sen micro-organismen onderling en tussen micro-organismen en gastheer. We hopen dat dit thema de hele Voorjaarsvergadering zal beheersen en dat communicatie tussen de verschillende geledingen die in de Voorjaarsvergadering participeren optimaal zal zijn.

  • Evaluation of Six Methods for Extraction and Purification of Viral DNA from Urine and Serum Samples
    NEW MICROBIOLOGICA, 29, 111-119, 2006 Evaluation of six methods for extraction and purification of viral DNA from urine and serum samples Massimiliano Bergallo, Cristina Costa, Giorgio Gribaudo, Sonia Tarallo, Sara Baro, Alessandro Negro Ponzi, Rossana Cavallo Department of Public Health and Microbiology, Virology Unit, University of Turin, Italy SUMMARY The sensitivity and reliability of PCR for diagnostic and research purposes require efficient unbiased procedures of extraction and purification of nucleic acids. One of the major limitations of PCR-based tests is the inhibition of the amplification process by substances present in clinical samples. This study used specimens spiked with a known amount of plasmid pBKV (ATCC 33-1) to compare six methods for extraction and purification of viral DNA from urine and serum samples based on recovery efficiency in terms of yield of DNA and percentage of plasmid pBKV recovered, purity of extracted DNA, and percentage of inhibition. The most effective extraction methods were the phenol/chloroform technique and the silica gel extraction procedure for urine and serum samples, respectively. Considering DNA purity, the silica gel extraction procedure and the phenol/chloroform method produced the most satisfactory results in urine and serum samples, respectively. The presence of inhibitors was overcome by all DNA extraction techniques in urine samples, as evidenced by semiquantitative PCR amplification. In serum samples, the lysis method and the proteinase K procedure did not completely overcome the presence of inhibitors.

  • Advancing Gene Fusion Detection Towards Personalized Cancer Nanodiagnostics Kevin Maisheng Koo Bachelor of Science (Hons I)
    Advancing Gene Fusion Detection towards Personalized Cancer Nanodiagnostics Kevin Maisheng Koo Bachelor of Science (Hons I) A thesis submitted for the degree of Doctor of Philosophy at The University of Queensland in 2017 Australian Institute for Bioengineering and Nanotechnology Abstract Prostate cancer (PCa) is one of the most prevalent non-cutaneous cancers in men, and is also one of the most lethal oncogenic diseases that accounts for a vast majority of male cancer-related deaths. Currently, widespread PCa screening is reliant on the prevailing usage of the FDA-approved blood- based prostate specific antigen (PSA) biomarker. Yet, landmark clinical trials in recent years have indicated that serum PSA screening holds a substantial risk of over-diagnosing low grade indolent PCa which are unlikely to result in mortality. Consequently, this paucity of accurate disease risk stratification during PCa screening has led to a variety of health burden associated with unnecessary biopsies, and over-treatment in a considerable fraction of patient population. Given that the screening shortcoming of the PSA test is outweighing its benefit, there is a clear need for better strategies to improve PCa risk stratification and accurately detect high-grade aggressive PCa molecular subtypes at an early stage for timely personalized treatment. To address this PCa screening conundrum, the research work described in this thesis primarily embodies a bipartite strategy which pairs together the use of next-generation PCa-specific molecular biomarkers, and the development of innovative nanodiagnostic technologies to target these superior biomarkers. In recent years, massive advances in next-generation sequencing techniques have led to the discoveries of novel PCa molecular targets which possess excellent PCa- specificity (i.e.

  • Amplication of 0.7Kb Fragment Katg Gene from Clinical Multi Drug Resistant Tuberculosis Isolate in Bali
    Indonesian Journal of Biomedical Sciences Volume 7, Number 2, July-December 2013: 69-72 Print-ISSN: 2085-4773, E-ISSN: 2302-2906. AMPLICATION OF 0.7KB FRAGMENT KATG GENE FROM CLINICAL MULTI DRUG RESISTANT TUBERCULOSIS ISOLATE IN BALI 1Dwiputri, A. W., 2Ratnayani, K., 1Yowani, S. C. 1Department of Pharmacy, Faculty of Mathematics and Natural Sciences, Udayana University, Bali-Indonesia 2Department of Chemistry, Faculty of Mathematics and Natural Sciences, Udayana University, Bali-Indonesia ABSTRACT During last decade has seen a particular increase in the occurrence of drug-resistant of tuberculosis (DR-TB) and multi-DR strains, such as Isoniazid (INH) resistant strains of M. tuberculosis. INH resistance is more frequently associated with mutations in the katG gene. Detection of katG gene mutations can be performed by PCR technique, followed by sequences. The aim of this study is to amplify katG gene region (0,7 Kb) from clinical isolate of MDR-TB in Bali. DNA isolation for PCR was done by Boom method and katG gene amplification was performed under the following conditions: predenaturation at 950C for 15 min; fourty cycles of denaturation at 940C for 1 min, annealing at 560C for 1 min, extension at 720C for 2 min; final extension at 720C for 10 min. The amplicons were detected by 1.5% agarose gel electrophoresis and showed a specific band size at 0.7 kb. This suggests that the fragment of katG gene has been successfully amplified in these areas. Keywords: amplification, katG gene, MDR-TB, 0.7 Kb INTRODUCTION we designed new primers with a longer area of Tuberculosis, caused by M.

Submitted: April 09, 2007; Returned to authors for corrections: January 23, 2008; Approved: July 04, 2008. ABSTRACT Since Mycoplasma hyopneumoniae isolation in appropriate media is a difficult task and impractical for daily routine diagnostics, Nested-PCR (N-PCR) techniques are currently used to improve the direct diagnostic sensitivity of Swine Enzootic Pneumonia. In a first experiment, this paper describes a N-PCR technique optimization based on three variables: different sampling sites, sample transport media, and DNA extraction methods, using eight pigs. Based on the optimization results, a second experiment was conducted for testing validity using 40 animals. In conclusion, the obtained results of the N-PCR optimization and validation allow us to recommend this test as a routine monitoring diagnostic method for Mycoplasma hyopneumoniae infection in swine herds. Key-words: Swine Enzootic Pneumonia, Mycoplasma hyopneumoniae, diagnosis, Nested- PCR. INTRODUÇÃO Nowadays, fastidious microorganisms have been detected by molecular biology techniques, such as DNA or RNA Mycoplasma hyopneumoniae (M. hyopneumoniae) is the hybridization and Polymerase Chain Reaction (PCR). These primary etiological agent of the Swine Enzootic Pneumonia (SEP), techniques are faster and more specific for microorganism that leads to a non-productive cough, mild fever, weight gain detection (6); and since mycoplasmas isolation is impractical in loss, high morbidity, and low mortality (12,17).

  • Design & Fabrication of Microfluidic DNA Extraction Device for Water
    DESIGN & FABRICATION OF MICROFLUIDIC DNA EXTRACTION DEVICE FOR WATER QUALITY MONITORING DESIGN & FABRICATION OF MICROFLUIDIC DNA EXTRACTION DEVICE FOR WATER QUALITY MONITORING By Bo Dang, B.ENG. B. Eng. (McMaster University, Ontario, Canada) A Thesis Submitted to the School of Graduate Studies In Partial Fulfillment of the Requirements For the Degree Master of Applied Science McMaster University © Copyright by Bo Dang, September 2012 MASTER OF APPLIED SCIENCE (2012) McMaster University (Mechanical Engineering) Hamilton, Ontario, Canada TITLE DESIGN & FABRICATION OF A MICROFLUIDIC DNA EXTRACTION DEVICE FOR WATER QUALITY MONITORING AUTHOR Bo Dang, B.Eng. SUPERVISOR Professor P. R. Selvaganapathy Department of Mechanical Engineering NUMBER OF PAGES XIX, 119 i ABSTRACT Continuous monitoring of pathogens that may be present in water is one of the key preventive measures that can be used in rural areas of developed countries and developing countries to reduce chances of the water borne diseases outbreak. Off-site testing of microbiological contamination of water is conventionally done for monitoring water quality. However, such a process is time consuming and involves using a variety of hazardous reagents. To address these issues, a portable device for rapid detection of unsafe water is needed. One of the key components in this system is to extract DNA from the pathogens. The primary consideration for DNA extraction is to separate DNA from proteins and other cell debris in the lysate solution. The pure population of DNA molecules are then sent downstream for subsequent processing such as real-time PCR (Polymerase Chain Reaction) and BioFET sensors for further identification and analysis. The focus of the thesis will be on the fabrication of a microfluidic DNA extraction system that can achieve high DNA extraction efficiency and a good repeatability.

  • Tularemia – Epidemiology
    This first edition of theWHO guidelines on tularaemia is the WHO GUIDELINES ON TULARAEMIA result of an international collaboration, initiated at a WHO meeting WHO GUIDELINES ON in Bath, UK in 2003. The target audience includes clinicians, laboratory personnel, public health workers, veterinarians, and any other person with an interest in zoonoses. Tularaemia Tularaemia is a bacterial zoonotic disease of the northern hemisphere. The bacterium (Francisella tularensis) is highly virulent for humans and a range of animals such as rodents, hares and rabbits. Humans can infect themselves by direct contact with infected animals, by arthropod bites, by ingestion of contaminated water or food, or by inhalation of infective aerosols. There is no human-to-human transmission. In addition to its natural occurrence, F. tularensis evokes great concern as a potential bioterrorism agent. F. tularensis subspecies tularensis is one of the most infectious pathogens known in human medicine. In order to avoid laboratory-associated infection, safety measures are needed and consequently, clinical laboratories do not generally accept specimens for culture. However, since clinical management of cases depends on early recognition, there is an urgent need for diagnostic services. The book provides background information on the disease, describes the current best practices for its diagnosis and treatment in humans, suggests measures to be taken in case of epidemics and provides guidance on how to handle F. tularensis in the laboratory.

  • Branched Dna Nanostructures for Molecular Diagnostics
    BRANCHED DNA NANOSTRUCTURES FOR MOLECULAR DIAGNOSTICS A Dissertation Presented to the Faculty of the Graduate School of Cornell University in Partial Fulfillment of the Requirements for the Degree of Doctor of Philosophy by Mark Richard Hartman August 2013 © 2013 Mark Richard Hartman ALL RIGHTS RESERVED ii BRANCHED DNA NANOSTRUCTURES FOR MOLECULAR DIAGNOSTICS Mark Richard Hartman, Ph.D. Cornell University 2013 DNA nanotechnology has been enormously successful in using DNA as a nanoscale construction material, and consistent progress in using increasingly complex DNA- mediated assemblies and designs has been reported in the literature. However, the field of DNA nanostructures has sometimes been lacking for concrete applications. Meanwhile, DNA has also been widely used as probes and primers for nucleic acid diagnostics applications, and this provides an extremely critical application with potential for great medical benefits, and these DNA probes and primers are readily interfaced with DNA nanotechnology. Thus, in this Dissertation, I discuss the combination of (1) DNA in its role as a recognition element for nucleic acid detection, and (2) DNA as a structural material for nanoscale self-assembly. This combination represents a fusion of “structure” and “function”, and will ultimately lead to great advancements in the field of nucleic acid diagnostics. iii BIOGRAPHICAL SKETCH I received my B.S. degree in Chemical and Biomolecular Engineering from Cornell University in 2007. As an undergraduate with a minor in Biological Engineering, I worked with Prof. Dan Luo in the Biological and Environmental Engineering on the design and synthesis of DNA nanostructures and portable detection using DNA nanobarcodes. Upon graduation, I remained at Cornell and entered the Masters of Engineering program (2007 – 2008), where I worked on DNA-mediated self-assembly of gold nanoparticles.

  • CHAPTER 10: PCR for Detection and Characterization of Bacterial
    CHAPTER 10 PCR for Detection and Characterization of Bacterial Meningitis Pathogens: Neisseria meningitidis, Haemophilus influenzae, and Streptococcus pneumoniae I. Overview of PCR technologies In developing countries, the most commonly used approaches for detection and characterization of bacterial meningitis pathogens include culture, Gram stain, and latex agglutination. Although culture is considered the gold standard for case confirmation in clinics, the positive rate is relatively low due to suboptimal storage and transportation conditions, culture practice, and/or antibiotic treatment administered before the specimen is collected. While Gram staining is important, inexpensive, and should be performed whenever possible, it merely gives a clue as to the genus and species of the etiological agent. The reading of latex agglutination results is subjective and can be difficult to interpret, especially when a specimen’s bacterial load is low. It is also not feasible to do quality control on latex agglutination. Culture should be kept as the gold standard as cultured bacteria are sources of data for antibiotic susceptibility, complete subtyping, the expression of antigens that are to be included in future vaccines, and pathophysiology of isolates. Specimens that do not yield any culture can still be analyzed by molecular methods (see below) that can be applied on DNA extracted from clinical specimens (typically, blood and CSF). A. Polymerase chain reaction (PCR) PCR was developed in the mid- to late 1980s (36, 42) and is considered one of the most important methodological inventions in molecular biology. It is designed to permit selective amplification of a specific target DNA sequence(s) within a heterogeneous collection of DNA sequences (e.g., total genomic DNA).

Some phytoplankton can produce toxic blooms which are harmful to aquatic ecosystems and human health. Kariena brevis is responsible for Harmful Algal Blooms and produces brevetoxin which can lead to gastrointestinal and neurological problems in mammals. Traditional methods for Harmful Algal Bloom monitoring require sample collection and preservation for later study in laboratories where they are generally processed using microscopy which can take many hours or days. Laboratory equipment for this application has been adapted for ship-board use.
