FUVEST 2025 Aumenta nos hospitais brasileiros a presença de bactérias resistentes a antibióticos

This EVOLUTION question about ANTIBIOTIC-RESISTANT BACTERIA is important for discussing this dangerous ARTIFICIAL SELECTION topic in the context of PUBLIC HEALTH. In this question, we'll analyze a GRAPH on the effects of three antibiotics administered and analyze each alternative to understand the distractors and find the answer. Grab your materials and let's watch/study! Any questions, leave them in the comments. Kisses and hugs. I'm going! @biolopes CHAPTER 00:00 – Introduction 00:29 – Statement and Contextualization 02:58 – Graph Analysis 04:40 – Question Command and Analysis of Alternatives 08:37 – Important Message 08:54 – Tips for the Fuvest Exam QUESTION (FUVEST 2025) - The Presence of Antibiotic-Resistant Bacteria Is Increasing in Brazilian Hospitals. “The spread of antibiotic-resistant bacteria is a global nightmare. It is advancing rapidly and poses a threat to one of the greatest achievements of modern medicine: the ability to eliminate infections. Without effective antibiotics, it is nearly impossible to perform surgeries, transplants, and other treatments safely. Exposed to the appropriate concentration of antibiotics for a sufficient amount of time, bacteria easily die. If the dosage and duration of treatment are lower than necessary to kill them, some can survive and multiply, accumulating changes in their genetic material that allow them to escape the action of the drugs. Bacteria are everywhere: in water, soil, air, and surfaces, including our bodies. With the intensive use of antibiotics in human health and food production, bacteria are continually exposed to these drugs. This contact favors the selection of resistant strains.” Revista Pesquisa FAPESP – January 2024 (Adapted). The following graph illustrates the growth of a species of bacteria in a culture medium, with and without antibiotics. Three different antibiotics were tested (1, 2, and 3). -- Graph available in the video -- Considering the text and the graph, regarding bacterial resistance to antibiotics, the correct statement is: (A) The combination of more than one antibiotic during treatment reduces the amount of antibiotics released into the sewage system and the chances of mutant bacteria emerging in nature. (B) To reduce the chances of selecting resistant bacteria, it is necessary to increase the concentration of antibiotics present in nature and kill free-living pathogenic bacteria. (C) Random mutations that occur in bacteria, associated with prolonged exposure to antibiotics, contribute to the selection of antibiotic-resistant bacteria. (D) Antibiotic 3 will be effective, at the same concentrations used in the experiment, in treating infections caused by the bacterial strains present on day 16 of culture. (E) Among all the antibiotics tested, antibiotic 2 is the most effective in combating the bacteria in the experiment reported, while antibiotic 1 is the least effective. Answer: Alternative C (understand how to reach this alternative by watching the video until the end).
