The Antibiotic Resistance of MRSA is a multi-day activity that exemplifies how science teachers in mainstream high school biology (grade 9–12) classrooms with English learners (ELs) can facilitate students' sense-making of evolution by natural selection through contextualized, real-world issues while...
This lesson provides teachers with a hands-on activity to teach students about natural selection and then uses a video to connect natural selection to antibiotic resistance. Students will practice new terms with a worksheet and then can be assessed with a quiz. Introduction This lesson provides ...
“Natural” (in contrast to clinical) breakpoints consider a bacterial organism as resistant if its MIC is significantly higher than the modal MIC of a collection of strains of the same bacterial species, thus considering resistance as an “abnormally higher” MIC, which indicates some kind of ...
Antibiotic-resistant pathogens are profoundly important to human health, but the environmental reservoirs of resistance determinants are poorly understood. The origins of antibiotic resistance in the environment is relevant to human health because of the increasing importance of zoonotic diseases as well as...
In all cases, antibiotic selection should be based on site of infection and clinical presentation as evaluated by a healthcare professional, culture/sensitivity and other needed laboratory results, local resistance/susceptibility patterns, and patient-specific characteristics. In many instances, the care ...
Once entered into the microbiota, where intensive antibiotic selection exists, the antibiotic resistance gene pool is amplified and may further penetrate into the pathogenic microbiota. Another aspect of extensive antibiotic use is the release of antibiotics and the corresponding resistance genes into the...
Evolutionary trajectories are constrained by trade-offs when mutations that benefit one life history trait incur fitness costs in other traits. As resistance to tetracycline antibiotics by increased efflux can be associated with an increase in length of

Antibiotic resistance is a natural feature of diverse microbial ecosystems. Although recent studies of the antibiotic resistome have highlighted barriers to the horizontal transfer of antibiotic resistance genes between habitats, the rapid global spread of genes that confer resistance to carbapenem, colistin...
