You can not even imagine how many different kinds of bacteria exist. Physicians for convenience decided to distribute them all into two large groups: gram-negative and gram-positive bacteria. Differentiated harmful microorganisms according to the method of Gram. The principle of this method is based on the staining of bacteria with a special substance.
The main varieties of Gram-positive bacteria
Gram-positive are those bacteria that, after staining according to the Gram method, become dark-¬ violet. They live and reproduce in the environment, the organisms of animals and humans. Like many other bacteria, the representatives of the gram-positive group can very well co-exist with the person, without harming him, as long as their reproduction is impeded by strong immunity. As soon as the harmful organisms can find the opportunity to multiply, they will certainly use it.
Gram-positive bacteria include such species:
- staphylococci;
- mycobacteria;
- Listeria;
- peptococci;
- actinomycetes;
- bacilli;
- clostridia;
- streptococci ;
- lactobacilli and others.
Some of them in smears are classified as gram-positive anaerobic bacteria. These microorganisms are distinguished by the fact that they have the ability to survive where no oxygen is supplied. But in the fresh air they die almost instantly. Some members of the group of anaerobic Gram-positive microorganisms are able to form spores (for example, clostridia).
Treatment of infections caused by Gram-positive bacteria
The sooner the fight against bacteria is started, the faster, painlessly and effectively it will pass. As practice shows, truly effective can be considered only a medical method of treatment, including antibiotics. Only these drugs help to destroy all bacteria and restore the body after their effects.
Ordinary and aerobic gram-positive bacteria can be cured by such means:
- beta-lactams;
- macrolides ;
- oxazolidinones and others.
The main problem is that the bacteria have learned to adapt to most medications. And accordingly, antibiotics for some of the microorganisms to act ceased. Today, active development of new drugs is underway. Among the most effective modern tools:
- Daptomycin;
- Quinupristin;
- Tajciclin.
