Dr. Stefan Pukatzki is a Professor of Immunology and Microbiology at the University of Colorado in Denver. Dr. Pukatzki studies Vibrio cholerae, the bacterium that causes the human disease cholera. Cholera is a dangerous water-borne disease that rapidly spreads through human populations in large epidemics.  Dr. Pukatzki discovered that V. cholerae has a stabbing device, the Type Six Secretion system, that it uses to inject poisons into surrounding bacteria to kill them off and gain a competitive advantage.  This stabbing device is wide-spread through many types of bacteria, illuminating the violent interactions that regularly take place among microbes.  Dr. Pukatzki discusses Type Six Secretion, cholera, and serendipity.

Dr. Nathan Schmidt is an Assistant Professor of Microbiology and Immunology at the University of Louisville. Dr. Schmidt studies the parasite that is transmitted by mosquitoes and causes malaria, Plasmodium. Malaria is a prevalent parasitic disease around the globe that is estimated to kill up to 500,000 people every year.  Dr. Schmidt is interested in how the microbiome, which are the bacteria that are naturally found in the gut, influence the ability of a host to resist being infected with malaria.  Dr. Schmidt discusses malaria parasites, mosquitoes, and eradication efforts.

Dr. Girish Kirimanjeswara is an Assistant Professor of Immunology and Infectious Diseases at Pennsylvania State University. Dr. Kirimanjeswara studies bacteria that cause disease in humans, and how the immune system fights against these microbes. Selenium is a trace element that is found naturally in various environments, and Dr. Kirimanjeswara has become interested in the involvement of selenium in infectious disease.  Dr. Kirimanjeswara discusses trace elements, whooping cough, as well as his former life as a veterinarian, and the importance of vaccination.

Jeffrey Stott

Dr. Jeffrey Stott is a Professor of Microbiology and Immunology at the University of California, Davis. Dr. Stott studies the cause of an unusual tick-borne disease localized in cattle in California. Epizootic Bovine Abortion is caused by bacteria that cannot be grown in the laboratory, which has hampered the development of vaccines against this disease that leads to up to 5-10% of all cattle abortions in California. Dr. Stott discusses the search for an effective vaccine, as well as his interest in studying diseases in sea mammals like sea lions and dolphins.
