  • How They Work, Types, and the Rising Risk of Resistance

    How They Work, Types, and the Rising Risk of Resistance

    Antibiotics are essential in treating bacterial infections and have saved countless lives by targeting harmful bacteria in the body. They work by interfering with key processes that bacteria need to survive, helping reduce infection and restore health. Understanding how antibiotics function is important for using them safely and effectively.

    From common infections to serious hospital-acquired conditions, antibiotics play a central role in modern medicine. However, improper use can lead to antibiotic resistance, making infections harder to treat. Learning how these medicines work and how resistance develops helps ensure they remain effective for future generations.

    How Antibiotics Kill Bacterial Infections

    Antibiotics treat bacterial infections by targeting essential structures and processes within bacterial cells. They can be bactericidal, which kills bacteria, or bacteriostatic, which stops them from growing and multiplying. One key mechanism is disrupting the bacterial cell wall, where beta-lactam antibiotics like penicillin and amoxicillin block enzymes needed to build the wall, causing bacteria to weaken and burst. Another action is interfering with protein synthesis, as drugs like tetracyclines and macrolides bind to ribosomes and prevent protein production needed for survival.

    Other antibiotics, such as quinolones and rifampin, target DNA replication and RNA synthesis, stopping bacteria from reproducing. These combined effects reduce bacterial load and often lead to symptom improvement within 48–72 hours when used correctly. However, bacteria can develop resistance through enzymes, efflux pumps, or mutations, making infections harder to treat over time. According to the CDC, antibiotics work by targeting key bacterial functions to stop or kill bacteria.

    Common Antibiotics Types for Bacterial Infections

    Understanding the different types of antibiotics is important for treating bacterial infections effectively. Each type is designed to target specific bacteria or a broad range of organisms depending on the infection. According to the World Health Organization (WHO), choosing the correct antibiotic based on infection type and resistance patterns is essential for effective treatment and reducing antibiotic resistance.

    • Beta-lactam antibiotics: Includes penicillins and cephalosporins, which work by disrupting bacterial cell wall synthesis and are effective against many gram-positive infections.
    • Broad-spectrum antibiotics: These target a wide range of bacteria, including both gram-positive and gram-negative organisms, and are used when the exact infection is not yet identified.
    • Macrolides and fluoroquinolones: Macrolides are commonly used for respiratory infections, while fluoroquinolones treat a variety of infections such as urinary tract and respiratory conditions.
    • Reserve and strong antibiotics: Drugs like carbapenems and vancomycin are typically reserved for resistant infections such as MRSA and are used in more serious cases.

    Antibiotic Resistance Development and Prevention

    Antibiotic resistance develops when bacteria change over time and become less responsive to medicines designed to kill them. This can occur through genetic mutations or by acquiring resistance genes from other bacteria. According to the Centers for Disease Control and Prevention (CDC), responsible antibiotic use and proper stewardship are essential to slow resistance and preserve treatment effectiveness.

    • Genetic adaptation: Bacteria can mutate or acquire genes that help them survive antibiotic exposure, making treatments less effective.
    • Resistance mechanisms: Bacteria may produce enzymes that destroy antibiotics, alter drug targets, or use efflux pumps to remove the drug from their cells.
    • Overuse and misuse: Taking antibiotics unnecessarily or not completing prescribed doses increases the likelihood of resistance developing.
    • Prevention strategies: Using antibiotics only when needed, following prescriptions, maintaining hygiene, and getting vaccinated help reduce the spread of resistant bacteria.

    Stewardship Programs New Drug Development

    Antibiotic stewardship programs play a crucial role in controlling antibiotic resistance and promoting the safe use of antibiotics. These programs focus on ensuring the right antibiotic is prescribed at the right dose and for the correct duration. By reducing unnecessary prescriptions and guiding proper use, hospitals and healthcare systems can improve patient outcomes while limiting the spread of resistant bacteria.

    New drug development is equally important in addressing the growing challenge of resistance. Researchers are exploring innovative approaches such as bacteriophage therapy, which uses viruses to target specific bacteria, and CRISPR-based treatments that can edit bacterial genes. These advancements provide promising alternatives, especially for infections that no longer respond to traditional antibiotics. Continued research, combined with strong stewardship efforts and global cooperation, helps ensure better control of bacterial infections and supports the development of safer, more effective treatments for the future.

    Antibiotics Resistance Prevention Treatment Guide

    Antibiotics remain one of the most important tools in treating bacterial infections, but their effectiveness depends on proper use and responsible practices. Understanding how they work, the different types available, and the risks of antibiotic resistance helps improve treatment outcomes and preserve their effectiveness.

    By following prescribed treatments, avoiding misuse, and supporting stewardship efforts, individuals can help reduce the spread of resistant bacteria. With continued education and advancements in medicine, antibiotics will continue to play a vital role in protecting health and treating infections safely.

    Frequently Asked Questions

    1. What are antibiotics and how do they work?

    Antibiotics are medicines used to treat bacterial infections. They work by killing bacteria or stopping their growth. Some target the bacterial cell wall, while others interfere with protein or DNA processes. This helps the immune system clear the infection more effectively.

    2. What is antibiotic resistance?

    Antibiotic resistance happens when bacteria evolve and survive treatments that once killed them. This makes infections harder to treat and may require stronger or alternative medications. It is often caused by overuse or misuse of antibiotics. Proper usage helps slow down resistance development.

    3. What are broad-spectrum antibiotics?

    Broad-spectrum antibiotics target a wide range of bacteria, including both gram-positive and gram-negative types. They are often used when the exact cause of an infection is unknown. However, they can also affect beneficial bacteria in the body. Doctors usually prescribe them carefully to reduce resistance risks.

    4. Why is it important to finish an antibiotic course?

    Finishing the full course ensures that all bacteria are eliminated from the body. Stopping early can allow some bacteria to survive and develop resistance. This may lead to recurring or harder-to-treat infections. Completing the course helps maintain antibiotic effectiveness.

  • Antibiotic Resistance, Cultivated Meat, and Our Health 

    Antibiotic Resistance, Cultivated Meat, and Our Health 

    Medically important antibiotics are being squandered by animal agriculture to compensate for typical factory farming practices.

    Cultivating muscle meat directly from cells instead of raising and slaughtering animals would reduce the risk of foodborne illnesses “due to fecal contamination during slaughtering and evisceration of carcasses” because there would be no feces, no slaughter, and no carcasses to eviscerate. In addition, cultivating meat would also reduce the threat from antibiotic resistance.

    To compensate for overcrowded, stressful, and unhygienic conditions on factory farms, animals are typically dosed en masse with antibiotics. A lot of antibiotics. About 20 million pounds of medically important antibiotics a year, as you can see here and at 0:57 in my video, The Human Health Effects of Cultivated Meat: Antibiotic Resistance. 

    In the United States, for example, farm animals are given about 2 million pounds of penicillin drugs and 15 million pounds of tetracyclines annually. This is madness. 

    Antibiotic drugs important to human medicine go right into the feed and water of animals like cows, pigs, and chickens, by the ton and by the thousands of tons, as shown below and at 1:02 in my video. And that is all without a prescription.

    Ninety-seven percent of the tens of millions of pounds of antibiotics given to farm animals in the United States are bought over the counter—without a prescription or even an order from a veterinarian, as seen here and a 1:24. To get even a few milligrams of penicillin, we need a doctor’s prescription, because these are miracle wonder drugs that can’t be squandered. Meanwhile, farmers can just back their trucks up to the feedstore. 

    Now, half the Salmonella in retail meat—chicken, turkey, beef, and pork—is resistant to tetracycline, as shown below and at 1:50 in my video. About a quarter of the bugs are now resistant to three or more entire classes of antibiotics, including some resistant to “cephalosporins such as ceftriaxone [which] are critically important drugs we use to treat severe Salmonella infections, especially in children.” 

    Such agricultural applications for antimicrobials are now considered an “urgent threat to human health.” “The link between antibiotic use in animals and antibiotic resistance in humans is unequivocal.”

    As shown here and at 2:20 in my video, it all starts with the poop. 

    Antibiotic-resistant bugs are selected for and then can spread via meat or produce contaminated by poop or they can spread through the wind, the air, or the water, or be carried by insects. There are many pathways by which resistant superbugs can escape. So, even if you don’t eat meat, you can be “put at risk by the pathogens released from stressed, immunocompromised, contaminant-filled livestock” dosed with antibiotics. That’s one of the reasons the American Public Health Association called for a moratorium on factory farms, due in part to all the pollution from concentrated animal feed operations (CAFOs) to the surrounding communities. 

    Every year, more than five tons of animal manure are produced for every man, woman, and child in the United States. Again, it all starts with the poop. But cultivated meat means no guts, no poop, no fecal infections, and no antibiotics necessary. It also means no fecal or antibiotic residues left in “foodstuffs such as milk, egg, and meat” that can potentially cause a variety of side effects beyond just the transfer of antibiotic-resistant bacteria to humans.

    And, as you can see here and at 3:30 in my video, things are getting worse, not better. U.S. animal agriculture is using more antibiotics now than ever.

    This isn’t only because more animals are being raised for food, either. Antibiotic sales in the United States are outpacing meat production. Yes, meat production is going up, but there is a serious rise in antibiotic sales for meat production, as shown below and at 3:46.

    With the combined might of Big Ag and Big Pharma (who profit from selling all the drugs), it’s hard to imagine anything changing on the political side. The only hope may be a change in the production side.

    “The unstoppable rise of super-resistant strains of bacteria is a serious worldwide problem, resulting in 700 000 deaths every year,” and the projections for global antibiotic use in the production of farm animals are “ominous,” estimated to exceed 100,000 tons of antibiotics pumped into animals raised for food by 2030. Quite simply, we may be “on the path to untreatable infections” by using even some of our “last resort antibiotics,” like carbapenems, just to shave a few cents off a pound of meat.

    And it’s not just foodborne bacteria. Mad cow disease, swine flu, and bird flu have the potential to kill millions of people. Skeptical? I’ve got a book for you to read, whose author’s “superb storytelling ability makes every page of the book interesting and fascinating for both specialist and layperson.” (Thanks, Virology Journal, for the wonderful book review and calling my book “a must read.”)

    Given the threat of the chickens coming home to roost, an editorial in the American Journal of Public Health thought that “it is curious, therefore, that changing the way humans treat animals—most basically, ceasing to eat them or, at the very least, radically limiting the quantity of them that are eaten—is largely off the radar as a significant preventative measure. Such a change, if sufficiently adopted or imposed, could still reduce the chances of the much-feared influenza epidemic…Yet humanity does not consider this option.”

    That may be moot, though, because we could cultivate all the chicken we want, without guts or lungs.

    It’s hard to stress the importance of that American Journal of Public Health editorial. As devastating as COVID-19 has been, it may just be a dress rehearsal for an even greater threat waiting in the wings—the wings of chickens.

    According to the Centers for Disease Control and Prevention, the leading candidate for the next pandemic is a bird flu virus known as H7N9, which is a hundred times deadlier than COVID-19. Instead of 1 in 250 patients dying, H7N9 has killed 40 percent of the people it infects.

    The last time a bird flu virus jumped directly to humans and caused a pandemic, it triggered the deadliest plague in human history—the 1918 pandemic that killed 50 million people. That had a 2 percent death rate. What if we had a pandemic infecting billions where death was closer to a flip of a coin?

    The good news is that there is something we can do about it. Just as eliminating the exotic animal trade and live animal markets may go a long way toward preventing the next coronavirus pandemic, reforming the way we raise domestic animals for food may help forestall the next killer flu. The bottom line is that it’s not worth risking the lives of millions of people for the sake of cheaper chicken.

  • Self-Care Is an Act of Resistance

    Self-Care Is an Act of Resistance

    Grass-roots meditation activist Shelly Tygielski offers 3 ways to practice self-care so we can recharge, refresh, and rewire for action.

    This article was originally published in November, 2018.

    The day after the 2018 US midterms, after a bitter election season with hard-fought victories, severely-close losses, and some horrific violence in its wake, I found myself thinking back to a program I put together for the Women’s Convention the previous October in Detroit for thousands of impassioned, powerful women. We were all embarking on a journey we knew would be long and hard.

    I called my talk Self-Care Is an Act of Resistance: Shifting the Fight-or-Flight Response to Empathy-or-Action Response and here’s why.

    The main idea is that neither “fighting” nor “fleeing” are sustainable. More than that, they are responses we can move away from, we can evolve beyond. We often hear that our brains are hard-wired for fight-or-flight, that “we evolved this way,” but we know now that we continue to evolve. Our brains can be rewired.

    How can we evolve beyond fight-or-flight? By choosing to move towards two new responses: empathy and action. And I believe this starts with self-care.

    The Power of Empathy and Action

    I woke up the morning after the election to find over 100 messages in my inbox and via text with such a tone of despair. We had all worked hard, but so much more work remains.

    I started to respond, one by one, to the messages reminding everyone that they have PERMISSION to feel this way. It is okay to cry. To be sad. Disappointed. Tired. And in order to not add a secondary layer of emotion to everything we’re feeling— namely, guilt—we all have permission to pause, to reset, to breathe.

    It may feel inappropriate to take time to rest, or to seek out pleasure, or even indulge in some positivity in the midst of our heated social, political, and environmental climate. But I want you all to know that it’s crucial for us to acknowledge the importance of our own self-care and to act upon it. Self-care is not frivolous; self-care is a radical act of love.

    Yes, there is still work to be done. A lot of work to be done. But we don’t need to do it today. Today we can rest. Tomorrow we can rest. And then the next day and the next. We can pre-game for the holidays and think about all that we have to be grateful for, personally, and collectively. And then, those who are ready can rise up, dust off, unravel and lift up the rest of us.

    Self-care is a movement in and of itself.

    It’s a movement of love amidst defeat, of kindness in the face of loss as well as victory. It’s declaring yourself as self-deserving of emotional agency. Self-care is an act of resistance.

    Here are 3 ways to practice self-care today:

    1. Allow yourself to (finally) unplug from the news and social media for a few days. Turn off your alerts and push motivations, turn off the TV and don’t access social media. If you must access it for work or otherwise, limit your time and do not engage or comment on posts. It’s not forever—it’s a few days of peace and being off the grid. 
    2. Recognize when you are in need of self-care and then respond to that need. Sometimes taking time for self-care may impact the lives of those around you (for example, you need to take the day off from work or ask for someone to watch the kids). Inform those around you that you are responding to a personal need but do not feel the need to ask for permission. 
    3.  Have a self-care checklist ready that has dozens of options tailored just for you.  These self-care options can range from scheduling a mid-day call with a friend to drawing a bubble bath. Having this list ready is important because when you are on the verge of burnout, you may not have the capacity to come up with the options in that moment.
