FOCUS ON EVOLUTION
In patients infected with nonresistant strains of the tuberculosis bacterium, antibiotics can relieve symptoms in a few weeks. However, it takes much longer to halt the infection, and patients may discontinue treatment while bacteria are still present. How might this result in the evolution of drug-resistant pathogens?

Some advocate stockpiling the drug Tamiflu in the event of an influenza pandemic. Others point out that wealthy, Western nations would have an unfair advantage because developing nations (where the pandemic is most likely to start) would not have access to this expensive antiviral. Furthermore, some fear that indiscriminate use of the drug would promote the evolution of resistant flu strains. Given these caveats, do you think developed nations should stockpile Tamiflu for the protection and treatment of their citizens? Explain your answer
Which of the following does not apply to superbugs?
O
It is estimated that 70% of antibiotics used in the USA are
sold to animal farms.
O
The CDC reported that 1 million people in the U.S. may
contract a superbug every year in the USA.
O
The CDC predicts that 35,000 people will die yearly from
superbugs in the USA.
By the year 2050, antibiotic resistant bacteria may kill as
many as 10 million people in the world.
Select all the statements that are true regarding the drug treatments available for infectious diseases.□ Antiviral drugs are harder to develop than antibiotics because viruses must use our cellular machinery replicate. □ Very few anti-parasitic drugs exist because diseases caused by Eukaryotes are extremely rare all over the world.□ Fewer drugs are available to treat Eukaryotic pathogens because their physiology and functions are very similar to our own.□ Development of antiparasitic drugs are a low priority because the diseases they treat tend to occur in poor countries, and drug companies can't make money.□ Antivirals may quit working because rates of viral mutation are very high.□ There are more antiviral drugs than atibiotics because antiviral drugs are very easy and cheap to make.

- As humanity advances, many improvements have been made with the medical field. We now have the ability to: • Help correct bad vision (Glasses, contact lenses, laser surgery). • Allow diabetics a second chance (insulin shots). • Increase the life of cancer patients. (Chemo) • Correct bad teeth (orthodontic braces) • And much more. What is to be noted is that these diseases are genetic and long ago were enough to kill people with them (A near-sighted person would not be able to see dangers in front of them.) These people would not live long enough to pass on their genes. BUT now, genetic diseases like vison problems and diabetes are being passed on because their victims remain alive because of our medical advances. QUESTION: Are we interfering with our own evolution as a species? • If yes, why should we let these diseased people stay alive? What can they contribute to our evolution? • If no, has our evolution focused on a different selection pressure? What trait are we further evolving…arrow_forwardThere are concerns about overuse and misuse of antibacterial drugs, and the association of these with increased antibiotic resisstance in bacteria. Of the following, which best explains this? Antibiotic exposure directly causes many of bacterial in a population to mutate and develop new antibiotic resistance traits. If antibiotic use occurs repeatedly in a person, the dosage of the drug needs to be increased to work in a patient’s system because he/she will develop physiological tolerance to the antibiotic. Exposure to an antibiotic causes bacteria to die or become stronger; stronger bacteria will be better able to cope with additional exposures to any antibiotic drug, eventually becoming immune to all antibiotics. Antibiotics kill susceptible cells and even a small number of existing resistant bacteria that survive will become the majority of the population that remains, leading to populations that are resistant to this drug.arrow_forwardA malaria vaccine has proved to be 77% effective in early trials and could be a major breakthrough against the disease, says the University of Oxford team behind it. Malaria kills more than 400,000 people a year, mostly children in sub-Saharan Africa. But despite many vaccines being trialled over the years, this is the first to meet the required target. The researchers say this vaccine could have a major public health impact. When trialled in 450 children in Burkina Faso, the vaccine was found to be safe, and showed "high-level efficacy" over 12 months of follow-up. Larger trials in nearly 5,000 children between the ages of five months and three years will now be carried out across four African countries to confirm the findings. Malaria is a life-threatening disease caused by parasites that are transmitted to people through mosquito bites. Although preventable and curable, the World Health Organization estimates there were 229 million cases worldwide in 2019 and 409,000 deaths.…arrow_forward
- Why does the Ebola virus generate such severe symptoms in a human host? (Hint: What is the evolutionary explanation for why Ebola kills humans so quickly? I'm not asking "how" it kills its human host so quickly; I am asking "why" it kills its human host so quickly.)arrow_forwardWhy do scientists worry more about new strains of viruses like influenza and coronviruses as potential causes of deadly human pandemics, but they never talk about the next big Herpesvirus strain deadly pandemic? Which of the statements below helps partially answer that? We already have effective vaccines for Herpes. Influenza and CoV have more genes, more complex gene expression, and can undergo genetic recombination or reassortment, while Herpesviruses are more limited. Only humans get Herpesviruses, while animals can get Influenza viruses and Coronaviruses. dsDNA viruses aren't very transmissible and even when they are, they're not deadly. Influenza and CoV are RNA viruses which results in having higher mutation rates -- they can more easily jump between host species. Herpesviruses are dsDNA viruses and usually very host specific.

- An outbreak of Ebola between 2014 and 2016 resulted in 28,616 cases and 11,310 deaths in Guinea, Liberia and Sierra Leone. An additional 36 cases and 15 deaths were reported outside these 3 countries. This deadly disease urged the need for extensive research on Ebola to better understand and treat the disease and prevent future outbreaks. Ebola is a - SSRNA virus. What does this mean for how it is converted into proteins? Does this virus require additional machinery to be infectious? Can you hypothesize based on how it replicates in the cell what scientists might hope to target for treatment or prevention of Ebola?arrow_forwardIn 1887 a strange nerve disease attacked the people in the Dutch East Indies. The disease was beriberi. Symptoms of the disease included weakness and loss of appetite, victims often died of heart failure. Scientists thought the disease might be caused by bacteria. They injected chickens with bacteria from the blood of patients with beriberi. The injected chickens became sick. However, so did a group of chickens that were not injected with bacteria. One of the scientists, Dr. Eijkman, designed a new experiment based on his own observations. Before the experiment, all the chickens had eaten whole-grain rice, but during the experiment, the chickens were fed polished rice. Dr. Eijkman researched this interesting case and found that polished rice lacked thiamine, a vitamin necessary for good health. State the question or problem that Dr. Eijkman investigated. What was the original hypothesis? What was the manipulated (independent) variable and the responding (dependent) variable?

- Because of overuse of antibiotics and/or weakened governmental surveillance of infectious disease, several diseasesthat had been thought to be no longer a threat to humanhealth (e.g., pneumonia and tuberculosis) are rapidly becoming unmanageable. In several instances, so-called superbugs(microorganisms that are resistant to almost all known antibiotics) have been detected. How did this circumstancearise? What will happen if this process continues?arrow_forwardWhich of the following is NOT among the general strategies that bacteria, insect vectors, andtumor cells all use to evolve resistance to drug treatments include the following, except: a.
