Finding your perfect match – evolving technologies for bacterial strain typing

Brian Cantwell, Ph.D., Scientist, ATCC
September 15, 2016

Abstract: Bacterial strains within the same species can show a wide range of genetic differences, from only a few nucleotides to large chromosomal variations.  Identifying specific strains can provide important clues to antimicrobial resistance or virulence factors, and is central to epidemiological studies of disease outbreaks.  In this webinar, we will look at the variety of typing information used to identify strains in the ATCC catalog.  From traditional serological methods to various electrophoresis-based molecular methods and the latest applications of whole genome sequencing, we will discuss these technologies, their applications in current literature, and how ATCC is working to improve strain typing by providing quality control and reference materials.

Key points:

  • The amount and type of strain difference within a given species of bacteria can differ widely and has given rise to a variety of strain typing technologies
  • Molecular methods have become predominant and have evolved from primarily electrophoresis-based methods, such as Pulse Field Gel Electrophoresis, to sequence-based methods, such as those based on one or more loci
  • Whole genome sequencing offers great promise for future typing as it offers both high resolution and the power of examining many loci, but comes with challenges in terms of quality control and data management
Biography: 

Dr. Cantwell has been with ATCC for three years and is the Microbiology Scientist with the ATCC’s Central Accessioning Unit.  He has a Ph.D. in Microbiology and has worked in the fields of bacterial pathogenesis, bacterial chemotaxis, microbial genetics, and biochemistry using both laboratory and bioinformatics approaches.

ATCC Quantitated Nucleic Acids – Empowering Molecular-based Assay Development

Fang Tian, Ph.D., Lead Scientist, ATCC Cell Systems
and
Cynthia Long, Product Line Business Manager, ATCC Microbiology Systems
September 22, 2016

Abstract: Molecular diagnostics are increasingly relied upon to direct appropriate therapies for the personalized treatment of cancer patients as well as to identify, track, and quantify pathogenic microorganisms. To ensure the reliability and reproducibility of these assays, authenticated controls with confirmed identity, stability, and functionality are required. In this presentation, we will discuss our growing portfolio of quantitative nucleic acids that have been purified or synthetically derived from characterized cell lines and microorganisms. With next-generation sequencing verified gene mutation allelic frequencies and virulence genes, as well as Droplet Digital™ PCR quantified absolute copy numbers, ATCC quantitative nucleic acids provide reliable and sustainable controls for oncology molecular diagnostic assays, infectious disease research, and quality control testing.

Key Points:

  • Human genomic DNAs with known mutational allelic frequency and copy number variation are essential control materials for developing molecular diagnostic tests
  • Quantitative microbial nucleic acids are critical for the development of assays designed for the detection and quantification of pathogenic strains
  • ATCC quantitative nucleic acids are ideal for use in inclusivity/exclusivity testing, establishing limits of detection, and validating or comparing test methods

Improving the Detection of Shiga Toxin-producing Escherichia coli

Cara Wilder, Ph.D., Technical Writer, ATCC
August 18, 2016

Abstract: In the food industry, providing safe products and protecting the company brand is of the utmost importance. To help food manufacturers, processors, and contract testing laboratories ensure the safety of consumable goods, ATCC offers an expanding portfolio of quality control strains to help support the routine verification of raw beef manufacturing trimmings for Shiga toxin-producingEscherichia coli (STEC). In this presentation, we will discuss the growing concern on food-borne illnesses, the importance of quality control strains in food safety, and ATCC STEC reference materials that support this need.

Key points:

  • Food-borne illnesses are a widespread problem that affect tens of millions of people throughout the United States every year
  • ATCC acquires, authenticates, and distributes clinically relevant food-borne pathogens that are essential for use as quality controls in food safety programs
  • Toxigenic, non-toxigenic, and reporter-labeled STEC strains are available from ATCC

Biography: 

Dr. Wilder is the Technical Writer for ATCC Microbial Systems. She has a Ph.D. in Microbiology with background experience working with several pathogenic bacterial species in both in vitro and in vivoenvironments. Dr. Wilder is the author of numerous publications on varying topics of scientific relevance, including quality control, microbial contamination, assay development, proficiency testing, and multidrug resistance.
