Food Science & Technology: Personnel

Michael Doyle

Description of Research Interests

• Dr. Doyle's research is in the area of food microbiology and focuses on bacterial foodborne pathogens.
• Pathogens under study include Escherichia coli O157:H7 and other serotypes of enterohemorrhagic E. coli, Salmonella spp., Campylobacter jejuni, Listeria monocytogenes, Staphylococcus aureus, and Clostridium botulinum.
• Development of probiotic/competitive exclusion bacteria to reduce/eliminate carriage of E. coli O157:H7 by cattle and Campylobacter jejuni by poultry.
• Development of treatments using approved chemicals to kill foodborne pathogens on produce, meat and poultry.
• Development of methods to isolate Helicobacter pylori from foods.
• Studies on the infectious dose of Listeria monocytogens
• Studies on the ecology of Salmonella typhimurium DT₁₀₄
