IDRI’s 6th annual Geek Gift Guide

The clock is ticking; the pressure is on. It’s time to buy holiday gifts! The question is: what are you going to get your favorite geek? As a scientific organization, IDRI is full of self-proclaimed geeks who have a few ideas to share in IDRI’s 6th annual “Gifts for Geeks” guide. Many of this year’s suggestions follow a food-related theme -- perfect for the wanna-be chef in your life! Bryan Berube suggests The Food Lab by J. Kenji Lopez-Alt. “If you are a scientist who doesn’t know how to cook, this book is for you,” said Berube, a postdoctoral scientist in IDRI’s Tuberculosis Discovery Research group. “The author performs scientifically controlled experiments to substantiate or debunk traditional kitchen lore. This cookbook goes into great detail about the science behind cooking and allows you to truly understand what you’re doing in the kitchen.” For the chemist in your crowd, Eduard Melief, [...]

TB and Antimicrobial Resistance Go Hand-in-Hand

Every year the World Health Organization releases its global report on tuberculosis. For the past few years, this has provided sobering reading. Tuberculosis is the biggest killer among infectious diseases, surpassing both AIDS and malaria. In 2016, there were 1.7 million deaths from TB, including 250,000 children. Although deaths from TB are slowly decreasing, the number of new cases was still reported at a staggering 10.4 million, which does not include patients still being treated or people with latent infection. Another major problem is drug resistance. The World Health Organization estimated 600,000 cases with multiple drug resistance, of which only one-fifth receive proper treatment. Much attention is now being paid to antimicrobial resistance (AMR); in fact, Nov. 13-19, 2017, is being observed as World Antibiotic Week with a focus on the responsible use of antibiotics that can help reduce the threat of resistance. But, keep in mind, TB is the major [...]

Hurricane Harvey Highlights Need for Vaccines

When a natural disaster – like Hurricane Harvey – hits, one of the immediate effects is often flooding. As waters rise, people and animals are in danger and become displaced. With the onslaught of rain during Harvey, contact with water is unavoidable. However, it’s the aftermath of the disaster that often poses a massive threat in the form of a host of infectious diseases – and also highlights the great need for continued vaccine development to protect or treat disease. The lack of safe water and sanitation facilities, coupled with the close proximity of people crowded into shelters, proves to be a breeding ground for disease outbreaks. If drinking water becomes contaminated after a disaster, it raises the likelihood of outbreaks of diarrheal diseases, cholera, Hepatitis A and typhoid fever. Crowded conditions also make it easier for infectious diseases – especially those that are airborne -- to move rapidly from [...]

Chagas Disease: The Kiss of Death?

It’s sometimes called “the kiss of death.” American trypanosomiasis, more commonly known as Chagas disease, is classified as one of the 10 most important neglected tropical diseases by the World Health Organization (WHO). It’s caused by the bite of a bug from the Triatominae family, commonly referred to as “kissing bugs”, that directly transmit the parasite T. cruzi to mammals, including humans, through their feces after they have bitten and taken a blood meal from their host. How do they do this? By biting humans around their lips and faces as they sleep – hence the nickname “kissing bugs.” Endemic in Mexico, Central and South America, an estimated 8 million people are infected by the protozoan parasite Trypanosoma cruzi (T. cruzi infection), resulting in at least 10,000 directly attributable deaths per year. Given that surveillance and diagnostic testing for Chagas disease is limited, the true disease and mortality burden are [...]

True Detective: Diagnosing the Hard to Detect

Over the years, IDRI has developed expertise in diagnosing the hard to detect – from leprosy, which was determined based on hard-to-recognize clinical symptoms, to leishmaniasis, which previously utilized painful procedures including aspirating liver or spleen tissue. Malaria also has a somewhat complicated process for detection. It relies on reviewing clinical symptoms and looking for malaria parasites in the blood under a microscope, which is not simple or easy to do. And, it doesn’t provide information related to whether or not transmission of infection is ongoing or is eliminated. Recently, I was invited to by the Bill & Melinda Gates Foundation and the Institut Pasteur to attend a malaria serology workshop in Paris. Following the same pattern as many other diseases, there is current desire within the malaria field to generate simple tests that can be used to detect infected individuals and objectively quantify the extent of disease burden within [...]
