Food Safety 101 (MWV33)

Whether you are making lunch for work, school or a summer picnic, knowing what food to pack and how to prepare it can be the difference between enjoying your day or going home sick. From recent peanut butter and pistachio nut recalls to E. coli outbreaks associated with hamburger patties, people are increasingly concerned about the safety of the food they eat. Many illnesses can be prevented with proper food preparation and a clean kitchen.

Healthy Pet, Healthy You (MWV32)

Animal, human and environmental health are inexorably intertwined. Diseases are making the jump from animals to humans and vice-versa at an increasing pace. The emergence of animal borne diseases such as Avian flu, Ebola, and most recently H1N1 (swine flu), demonstrate the need for an integrated strategy across several scientific, medical and environmental fields for improved public health.



In this episode of MicrobeWorld Video, Dr. Mark Lutschaunig, director of the Governmental Relations Division of the American Veterinary Medical Association discusses the need for a holistic approach to human and animal health. He emphasizes that our ability to better predict when and where disease outbreaks are likely to occur depends on a strong relationship between veterinarians, doctors, and health agencies.

In addition, Dr. Ron Atlas, chair of the One Health Commission, gives an overview of the organization's mission to foster closer professional interactions, collaborations, and educational opportunities across the health sciences professions, together with their related disciplines, to improve the health of people, animals, and our environment.

This episode of MicrobeWorld Video was filmed at the Marian Koshland Science Museum in Washington, D.C., during one of their popular public science events. For more information about the Koshland Museum, upcoming events and online resources visit them online at www.koshland-science.org.

Tiny Conspiracies (MWV31)

Bacteria communicate with chemical languages that allow them to synchronize their behavior and thereby act as multi-cellular organisms. This process, called quorum sensing, enables bacteria to do things they can’t do as a single cell, like successfully infect and cause disease in humans.

Bonnie Bassler, Ph.D., the Squibb Professor of Molecular Biology at Princeton University and President-elect for the American Society for Microbiology, has been researching strategies that can interfere with quorum sensing and will hopefully yield novel antibiotics to prevent disease.



In this episode of MicrobeWorld Video we present the full presentation Dr. Bassler gave at the Marian Koshland Science Museum in Washington, D.C. on June 18, 2009. Not only does Dr. Bassler explain the mechanisms of bacterial communication, but she also puts forth her theories on how we can disrupt this communication for human benefit.

Biofuels in Puerto Rico (MWV30)

Puerto Rico is widely known as the "La Isla del Encanto," which translated means "The Island of Enchantment." And while its beaches, tropical rain forest, and biolumescent bays are wonders of nature, the island is not without its problems. From energy needs to economics, Puerto Rico shares many issues facing the rest of the world.

 

 

In this MicrobeWorld Video episode we talk with Nadathur S. Govind, Ph.D., Professor, Marine Sciences Department at the University of Puerto Rico, Mayaguez, and William Rosado, Marine Sciences Department at the University of Puerto Rico, Mayaguez, about the sustainable biofuel program they are launching in southwestern Puerto Rico.

According to Govind, the island's successful sugarcane industry died in the 1990's. In fact, local rum manufacturers now import their molasses from as far away as Malaysia. As a result, approximately 70 percent of the population in southwestern Puerto Rico is on welfare.

Govind believes he can rebuild the local economy by harnessing bacterial enzymes extracted from the guts of termites and shipworms (mollusks) found in the mangroves off the coast to break down the lignocellulose in sugarcane and hibiscus. The idea is that if he can bring agricultural production back to his community, he can use the crop waste to produce ethanol to supplement Puerto Rico's demand for fuel. And since the byproduct of ethanol is carbon dioxide, he also plans to use algae to capture the gas and produce biodiesel. The waste that he has left over can then be returned to the soil as fertilizer or given to livestock as feed, completing the cycle.

For more information about Govind's program please read the article, "Combining Agriculture with Microbial Genomics to Make Fuels," found in the American Society for Microbiology's Microbe magazine.

Germ Proof Your Kids (MWV26)

 

 

Parents are often presented with conflicting messages about germs and cleanliness. On the one hand, the news headlines warn us about dangerous "superbugs." On the other hand, there is growing concern that over-cleaning and excessive hygiene may weaken children's immune systems. Fortunately, there is real, vetted science available to help us understand how to best protect, without overprotecting, our kids.
