Only a few decades ago, antibiotics were considered to be wonder drugs because they worked so well to cure deadly diseases.
The antibiotic era began in 1929 with Alexander Fleming's observation that bacteria would not grow near colonies of the mold Penicillium. Doctors miss the "good old days," when the antibiotics they prescribed consistently cured their patients. If an infection needs to be controlled with antibiotics, a short-term, high-dosage prescription is preferable.
Just as mild doses can breed resistance, an incomplete regimen of antibiotics can let bacteria survive and adapt. If one particular drug doesn't help with a bacterial infection, you may be dealing with a resistant strain.
Unnecessary use of antibiotics for agricultural and livestock purposes may lead to the evolution of resistant strains.
Ultimately, recognizing bacteria as evolving entities and understanding their evolution should help us to control that evolution, allowing us to prolong the useful lifespan of antibiotics. Antimicrobials describe a broad group of drugs that are used to kill pathogens (germs that are foreign and potentially harmful to an individual) or impair their ability to reproduce. Antiviral agents are drugs that work to interfere with the viruses ability to replicate itself (make copies of itself).
Once the type of bacteria is identified, the lab technologist can report the type of antibiotics that work best against the specific bacteria. When patients are admitted with a serious infection, one of the hospital Infectious Disease Physicians will see the patient daily and participate in the treatment plan. As a number of strains of bacteria are becoming resistant to popular antibiotic medications, health experts and scientists are considering use of herbs for treating bacterial infections.

Ironically, though, many antibiotics have become less effective, precisely because they have worked so well and have been used so often. In the decades that followed this breakthrough discovery, molecules produced by fungi and bacteria have been successfully used to combat bacterial diseases such as tuberculosis and pneumonia. However, evolutionary theory suggests some specific tactics to help slow the rate at which bacteria become resistant to our drugs.
Given time, heredity, and variation, any living organisms (including bacteria) will evolve when a selective pressure (like an antibiotic) is introduced.
If you take antibiotics for a viral infection (like a cold or the flu), you will not kill the viruses, but you will introduce a selective pressure on bacteria in your body, inadvertently selecting for antibiotic-resistant bacteria. This is because you want to kill all of the illness-causing bacteria, leaving no bacterial survivors. If you are going to introduce a selective pressure (antibiotics), make it a really strong one and a long enough one to cause the extinction of the illness-causing bacteria and not their evolution. Giving a stronger dose of the same antibiotic just increases the strength of the same selective pressure — and may even cause the evolution of a "super-resistant" strain. Later, these strains will not be able to be controlled by antibiotics when it really is necessary. Broad spectrum antibiotics are very valuable when we do not know the cause of the infection, especially when patients are very ill. There are numerous herbs with proven antibiotic properties that have been used for centuries for treating bacterial infections.
You accept that you are following any advice at your own risk and will properly research or consult healthcare professional. Import charges previously quoted are subject to change if you increase you maximum bid amount. But evolutionary theory also gives doctors and patients some specific strategies for delaying even more widespread evolution of antibiotic resistance.


Basically, you want your bacteria to be "antibiotic virgins," so that if they someday get out of hand and cause an infection that your immune system can't handle, they can be killed by a readily available antibiotic. Instead, you might want to try an entirely different antibiotic that the bacteria have never encountered before. Preventive use of antibiotics on livestock and crops can also introduce antibiotics into the bodies of the humans who eat them. If the bacteria is sensitive to a specific antibiotic, the antibiotic will be effective in destroying the bacteria. As the herbal antibiotics are safe for health and can be consumed for a prolonged period they are considered as safer alternatives to pharmacological drugs.

Basically, if you are going to introduce a selective pressure (antibiotics), make it so strong that you cause the extinction of the illness-causing bacteria in the host and not their evolution into resistant forms. This new and different selective pressure might do a better job of causing their extinction, not their evolution. If the bacteria is resistant to an antibiotic, it needs to be switched to a more effective agent. Culinary herbs such as oregano, parsley, basil, bay leaf and cumin, in addition to enhancing the flavor of foods, also help in boosting the body’s ability to fight disease causing bacteria.
After a day or more, the culture is examined under a microscope to identify the shape and characteristics of any bacteria. We are careful to avoid over-use of antibiotics due to the risk that bacteria might become resistant to our antibiotics. This allows the physician to choose antibiotics that will work against a particular category of bacteria.
