These videos explore microbiological investigation of food- and water-borne pathogens, including epidemiological, immunological, culture-based and nucleic-acid based tools for investigating outbreaks.
Dr. Max Teplitski discusses factors that can reduce sources of infection in the tomato production chain, including levels of irrigation and fertilization, weather conditions, and cultivar selection.
Dr. Max Teplitski describes research on tomato varieties and maturity state as factors in Salmonella proliferation, showing that varieties with delayed ripening traits are more resistant to the pathogen.
In this series, Dr. Max Teplitski describes the steps involved in an outbreak investigation. In this video he explains how to detect an outbreak of a food- or water-borne illness and how to go about identifying its source.
Dr. Max Teplitski describes why and how to culture the pathogen responsible for an outbreak based on hypotheses developed from epidemiological surveys and patient symptoms and demonstrates laboratory techniques of culture-based analyses.
Dr. Max Teplitski describes nucleic acid-based testing as one method for pathogen detection, including avialable extraction kits and PCR procedures.
Dr. Max Teplitski reviews direct and indirect immunological tests for identifying pathogens and determining immunological response.
Dr. Max Teplitski describes what is typically the last step in an outbreak investigation, source tracking and pathogen fingerprinting to establishing that the strains of the pathogen isolated from the source and the patient are the same.
