antibiotic

It is called antibiotic to the substance that has the ability to eliminate or interrupt the growth and proliferation of various pathogenic microorganisms. This is because antibiotics can act like bactericidal or develop a action bacteriostatic.

Antibiotics can be synthesized in a laboratory or produced by a living organism. They have a level of toxicity that affects pathogens, but not host organisms, beyond eventual adverse reactions. That is why antibiotics are used to treat infections caused by bacteria in humans, animals and plants.

The usual thing is that antibiotics, when ingested by the being suffering from the infection, help to defend their body from the actions of the bacteria. As the days go by, the local organic response manages to strengthen until it is in a position to reverse the infectious process.

It is important to mention that, when the infection is viral (produced by a virus), antibiotics are not effective. On the other hand, if antibiotics are used in a way that is not correct in terms of dose or frequency, the bacteria can become resistant, exacerbating the problem. That is why it is essential to consult a doctor and not self-medicate.

The phenomenon known as bacterial resistance it occurs when bacteria become resistant to certain antibiotics, so that they are unable to kill them or prevent them from growing. One of the reasons why this can happen, as mentioned in the previous paragraph, is that the consumption of the antibiotic is carried out too frequently; on the other hand, it may also be due to the patient not taking all the medications that have been prescribed, believing that the cheapest ones are enough, for example.

When this happens, there are different ways to effectively counteract the action of bacteria. One of them, perhaps the most common, consists of opting for an antibiotic to which the bacteria have not had the opportunity to create resistance. In some cases, it becomes necessary to administer the drug intravenously. It is worth mentioning that it is not always possible to fight bacteria that have become resistant.

With regard to self-medication and inappropriate use of antibiotics, it is important first to distinguish between the diseases serious and temporary, which can disappear if we allow our natural defenses to act. We must not forget that we are the only living beings "dependent" on medicine, and that many times we come to believe that all the answers are in this science because we do not listen to our own body.

Faced with problems such as the flu and the common cold, it is best to let our body fight them naturally; in fact, since they are viral diseases, we should not take antibiotics in these cases. Of course, we may well strengthen our defenses with a good diet of fruits and vegetables rich in vitamins and essential nutrients.

Other diseases generally caused by viruses, which is why they should not be treated with antibiotics, are bronchitis, sore throat, some ear infections and nasal congestion. However, bronchitis can be related to the presence of bacteria in the lungs, as well as the pain throat can be due to pharyngitis caused by streptococcus bacteria and certain ear infections can arise from the action of a bacteria; When in doubt, it is always recommended to consult a health professional.

The penicillin it is one of the best known antibiotics. It allows to fight the bacteria of the genera Staphylococcus Y Streptococcus Yet the Escherichia coli, among other pathogens that affect the Health of the human being. The gentamicin, the meropenem and the cephalothin they are other widely used antibiotics.
