How do antibiotics fight infections?

essentially, antibiotics are selective poisons used to kill bacterial cells. The term freely is reflected in "against life". In some senses there are all things that kill cells, antibiotic; This includes poisons and toxins. Chemotherapy is antibiotics because it kills cancer cells and unfortunately some human cells. In most definitions, however, antibiotics are medicines that people use when they have bacterial infections. The former type is called bactericidal and the second bacteriostatic . The aim of antibiotics that can be made from naturally occurring fungi or chemical compounds is to harm bacterial cells that cause sick people without damaging human cells.

Scientists classify antibiotics by how they work or bacteria against which they are most effective. When bacteria can be killed, antibiotics of the diaphragm of bacterial cell membrane usually do this. They can also inhibit bacterial growth by bacterial cells from creating forTeins and acids that need to survive and reproduction.

In order for antibiotics to be effective, it is important to understand the structure of bacterial cells, which fortunately differ significantly from most animal and plant cells. Proteins or enzymes and DNA structure of bacterial cells are targeted through natural or chemically produced antibiotics, and at the same time scientists are looking for compounds that will only choose bacteria for attack and not plant and animal cells. It should be noted that these drugs only fight with infections caused by bacteria. They are completely ineffective against infections caused by viruses or mushrooms.

Some antibiotics are called a wide spectrum because they can be used to kill many different types of bacteria. Others are a narrow spectrum and only have a use against several specific types of bacteria. Most common infections such as Strep or Staph, with relayAt the same time, it is easy to treat with broad -spectrum drugs. Other, more resistant bacteria may require narrow spectral treatment.

Unfortunately, people host many types of bacteria and some types are quite beneficial. Wide -spectrum antibiotics leave the human cells themselves, but often affect good bacteria that people carry. This can lead to complications from drug use such as yeast infection or diarrhea.

trends in medicine include verification that people have bacterial infection before antibiotics prescribing. This method is more used because certain bacteria have developed, which are much more resistant to many therapeutic. Infections caused by Staphylococcus aureus resistant to methicillin (MRSA) are extremely difficult to treat regular wide-level antibiotics.

Over time, some strains of staff bacteria have become resistant to the treatment of penicillin-bacteria-based antibiotics, as well as all life forms, evolving. People with MRSA infections must alreadyto soak specialized medicines that are much harder on the body to kill bacteria. Excessive use of any type of antibiotic can create resistant bacteria that is very difficult to fight. Therefore, doctors are trying to ensure that they use these drugs only if they are really necessary to slow down the development of antibiotics resistant bacteria.
