In this presentation, we will introduce the mechanisms involved in the tolerance of biofilms to antibiotics. In continuation of this, we will talk about specific tolerance mechanism, oxidative stress and the development of mutational resistance.
Scientists who are working to discover new medicines often use robots to prepare samples of cells, allowing them to test chemicals to identify those that might be used to treat diseases. Students will meet a scientist who works to identify new medicines. She created free software that ''looks'' at images of cells and determines which images show cells that have responded to the potential medicines. Students will learn about how this technology is currently enabling research to identify new antibiotics to treat tuberculosis. Students will complete hands-on activities that demonstrate how new medicines can be discovered using robots and computer software, starring the student as ''the computer.'' In the process, the students learn about experimental design, including positive and negative controls.
This lesson describes the major components and functions of the immune system and the role of engineers in keeping the body healthy (e.g., vaccinations and antibiotics, among other things). This lesson also discusses how an astronaut's immune system is suppressed during spaceflight due to stress and other environmental factors.

The discovery of antibiotics less than 100 years ago revolutionized health care, making former deadly diseases treatable. Still many people especially in low-income countries do not have access to these life-saving drugs, while att he same time, in many other arts of the world over-consumption of antibiotics is driving antimicrobial resistance, threatening to throw us back 100 years in time.

Welcome to the Teachers' Corner of Small Things Considered. In this section, we include the posts we deem most adequate for teaching purposes. We have reorganized them into subject areas geared for a typical microbiology course. To date, this material has been used for various forms of intellectual enrichment, e.g., suggested readings, class presentations, a source of topics for term papers. You can also find here our Talmudic Questions, which we characterize as those whose answers cannot be found in Google. We are told that some of these questions have been used in exams ranging from tests for undergraduate courses to qualifying/prelims for graduate students.
Learn about the challenging research work of several of the outstanding fellowship students at Scripps Institution of Oceanography. Explore topics such as antibiotics from the sea, the declining health of our oceans, mapping the seafloor, and factors affecting climate change. (57 minutes)
Overprescription and misuse of antibiotics has fueled the rise of antibiotic-resistant bacteria. That's why researchers are looking to the past for future alternatives. You'll hear about one possibility in this Science Update.
Rapamycin is a small molecule originally isolated from nature. It has antibiotic and immunosuppressive properties. It also allows two proteins which do not normally interact to bind together in the cell, which causes problems in the nutrient-sensing pathway.
MRSA stands for methicillin-resistant Staphylococcus aureus, a type of bacteria that is resistant to several antibiotics.
This month, the World Health Organization announced that tuberculosis cases are on the decline for the first time in at least 20 years. We seem finally to be winning what has been a very long battle. Tuberculosis bacteria have been attacking us since modern humans began to migrate out of Africa around 40,000 years ago. If you enjoy classic literature, you'll be familiar with the cough, fever, and weight loss of consumption (the old-fashioned term for tuberculosis), which used to be a near certain death sentence. That changed when the aminoglycoside antibiotic streptomycin was discovered in 1943.
