The first beta-lactam antibiotic, penicillin, was discovered by accident.

Some are made through a series of chemical reactions that produce the substance used in the medication. Other antibiotics are at least partially made through a natural but controlled process. This process is often enhanced with certain chemical reactions that can alter the original substance to create a different medication.
Antibiotics are powerful medications that work very well for certain types of illnesses. However, some antibiotics are now less useful than they once were due to an increase in antibiotic resistance. Antibiotic resistance occurs when bacteria can no longer be controlled or killed by certain antibiotics. In some cases, this can mean there are no effective treatments for certain conditions.
Each year, 2 million people are infected with bacteria that are resistant to antibiotics, resulting in at least 23, deaths. When you take an antibiotic, the sensitive bacteria are eliminated. The bacteria that survive during antibiotic treatment are often resistant to that antibiotic.
These bacteria often have unique characteristics that prevent antibiotics from working on them. The overgrowth of this type of bacteria causes infection in both your small and large intestines. These bacteria often infect your bloodstream, urinary tract, or surgical wounds. This infection typically occurs in people who are hospitalized.

What are resistant bacteria? Bacteria can develop resistance to certain medicines: Medicine resistance happens when bacteria develop ways to survive the use of medicines meant to kill or weaken them.
When are antibiotics needed? Reactions to antibiotics can be serious and sometimes fatal. They are called anaphylactic reactions.
People with reduced liver or kidney function should be cautious when using antibiotics. This may affect the types of antibiotics they can use or the dose they receive. Likewise, women who are pregnant or breast-feeding should speak with a doctor about the best antibiotics to take.

Complete the whole course of medication to prevent the return of the infection. Stopping the medication before the course has finished increases the risk that the bacteria will become resistant to future treatments.
The ones that survive will have had some exposure to the antibiotic and may consequently develop resistance to it. An individual needs to complete the course of antibiotic treatment even after they see an improvement in symptoms. Do not take some antibiotics with certain foods and drinks. Take others on an empty stomach, about an hour before meals, or 2 hours after. Follow the instructions correctly for the medication to be effective. People taking metronidazole should not drink alcohol.
Avoid dairy products when taking tetracyclines, as these might disrupt the absorption of the medication. Read the article in Spanish. A recent study brings us a few steps closer to treating certain bacterial infections with bacteria-killing viruses called bacteriophages.
