    Causes of meningitis

    Causes and mechanism for the development of meningitisUnder the word ourselves «meningitis» The inflammation of the shells of the brain is implied, and the cause of this inflammation can be a huge number of microorganisms - bacteria, viruses, fungi. Infectiousons not without confidence state that under certain conditions, any microorganism can cause meningitis in a person of any age. From here it is clear that meningitis are different - different and the speed of development, and in terms of the severity of the state, and in the frequency of occurrence, and, that is especially important, according to methods of treatment. Combines all meningitis one - the real threat to life and the high probability of complications.

    For the development of meningitis, a specific causative agent should get into the cavity of the skull and cause inflammation of the shells of the brain. Sometimes it happens when the foci of infection occurs in the immediate vicinity of the brain shells - with purulent otitis (inflammation of the middle ear), for example, or during hymorites. Often, the cause of meningitis is the brain injury. But most often in the cavity of the skull of the microbes fall with blood flow. Obviously, the very fact of microbe hitting in blood, the possibility of his «Skore» and subsequent reproduction on the brain shell due to the state of immunity.

    Meningita varieties

    Depending on the type of causative agent, meningitis are viral, bacterial, fungal. Some simplest (for example, amoeba and toxoplasm) can also cause meningitis.

    The development of viral meningitis can accompany the current of well-known infections - wind sieves, measles, rubella, epidemic vapotitis, the defeat of the brain shells occurs during influenza, in infections caused by herpes viruses. In weakened patients, in old people, the babies have meningitis caused by fungi (it is clear that in these situations it is the insufficiency of immunity plays a leading role in the occurrence of illness).

    Meningitis bacterial. Any purulent focus in the body - pneumonia, infected burn, angina, a variety of uluses and T.NS. - May be caused by meningitis, provided that the pathogen will fall into the blood and with a blood current will reach the brain shells. It is clear that all the well-known pathogens of purulent processes (staphylococci, streptococci, cinema sticks and t.D.) and in this case the causative agent of meningitis. One of the most terrible meningitis tuberculosis, almost forgotten, he is now meeting increasingly and more.

    At the same time, there is a microorganism that causes meningitis most often (60-70% of all bacterial meningitis). It is not surprising that he is called - Meningokokok. Infection occurs by air-droplet, meningococcus settles on the mucous membranes of the nasopharynx and can cause a state very similar to the usual respiratory viral infection - a small runny nose, redness of the throat - Meningococcal NazoFaring. But, meanwhile, the hitting of meningococcus in the body quite rarely leads to the occurrence of the disease - the leading role here belongs to completely special individual shifts in immunite.

    Development of meningitis

    The inability of the body to delay the microbe in the nasopharynk, is accompanied by penetration of meningococcus through the mucous membrane in blood. With blood current, it enters the brain shells, eyes, ears, joints, light, adrenal glands and in each of these organs may have a very dangerous inflammatory process. Accordingly, the defeat of the brain shells is accompanied by the development of meningococcal meningitis.

    Sometimes meningococcus falls into the blood quickly and in huge quantities. Meningococcal sepsis or meningococcusia arises - the most, perhaps, terrible of all children's infectious diseases. The microbe distinguishes toxins, under their impact there are multiple blockage of small vessels, blood clotting is broken, multiple hemorrhages appear on the body. Sometimes after a few hours after the start of the disease, blood pressure drops sharply and the person dies.
