What are the effects of tetanus?
The effects of tetanus come from bacterial neurotoxin released in the wound during infection. This substance blocks the ability of skeletal muscles to relax and instead make them contracts and convulsions. Blockjaw or similar muscle rigidity is a common symptom. Tetanus effects can be prevented by vaccination and are often successfully perverted in hospital environments that include respiratory support. In the developing world, Tetanus is a significant cause of death in newborns.
Clostridium tetani is a bacterium found in soil around the world, contaminating wounds in humans and other animals. The effects of tetanus are caused by strong neurotoxin, tetanospasmine, produced by bacteria and relaxing when their cells fall apart. When circulating the bloodstream, the toxin is gradually absorbed into the nerves, first peripherally and then into the spinal cord itself. In just a week, Tetanospasmin blocks the communication of the neurotransmitter, the preventceneurons that control the muscles when receiving commands from the brain. Inhibits muscle relaxation so koThe sterile muscles constantly have contractions.
Muscle contractions all over the body often start Lockjaw, one of the most important effects of tetanus. General muscle rigidity, difficulty in swallowing and paralysis follow. The patient is held by strong recurring convulsions that can tear muscles and ligament, and even broken by the vertebral column. If it reaches neurons in the brain stem, tetanic toxin threatens basic functions such as breathing. The smooth muscles of the heart do not develop tetans and can still relax because Tetanospas is only blocking the nervous control of the skeletal muscle ,.
Because it is rare in vaccinated individuals, tetanus is best prevented by vaccination at regular intervals, at least once every ten years for adults. Treatment includes antibiotics, muscle relaxants and hospitalized care. Because the most common cause of death from the effects of tetanus is respiratory failure, artificial respiration may be necessary, PODUD toxin suppresses normal breathing. The recovery rate is relatively high outside the elderly and some unnail patients. The mortality rate varies greatly from less than a tenth of cases in parts of the developed world to more than half in more poor countries.
In newborns, the effects of tetanus are similar to effects in adults, but follow a faster and often deadly course. Neonatal tetanus is often obtained from cutting the umbilical cord with a knife or scissors that are not properly sterilized, although contact with the soil can be a factor. It is a common cause of early mortality of infants in the developing world, albeit rare elsewhere. If the mother of the infant has been vaccinated, the neonatal chance of getting a decrease in tetanus, regardless of hygiene, because passive immunity can be obtained by the fruit during pregnancy.
