The name of the bacteria is shigella bacillus, which is the most common cause of dysentery. 米国では, signs and symptoms are typically mild and usually disappear within a few days. ほとんどの場合, people do not need to see a doctor.
If a person seeks medical help for dysentery in the U.S, it is the law that local authorities are informed and notified that this disease could affect the public.
Each year there are between 120 million to 165 million cases of shigella bacillus infection with or 1 million cases being fatal. オーバー 70 percent of the facilities are children under the age of 5 and are typically in developing countries.
Facts about Dysentery
- Dysentery refers to any cases where there is bloody diarrhea caused by an infection. Dysentery is also called bloody flux, flux, Montezuma’s Revenge and travelers dysentery.
- Dysentery kills over 700,000 people every year across the globe. Most victims are children and are typically poor, and lacking sufficient sanitation
- Every year bacillary dysentery kills approximately six times as many people as amoebic dysentery.
- Large outbreaks typically occur when bacillary dysentery have developed in communities where sewage mixes with drinking water. Amoebic dysentery is transmitted by contained water and is well known to travelers because of its prevalence in developing nations. しかしながら, there are cases of this occur in the industrialized countries.
- 推定 18,000 cases of shigellosis occur actually within the United States, affecting mostly the elderly, infirm, infants and those who are susceptible, as well as rural parts of Canada. In Western
- Europe and the U.S, this can also be generally found in people who recently visited the tropics or developing nations.
Causes of Dysentery
The causative organism is commonly found in water contaminated with human feces and is transferred via the fecal-oral route, Consuming contaminated water or consuming foods produced in containment water. Other causes include viral infection, parasitic worm infection or chemical irritation.
Dysentery symptoms occur in part due to the body’s response to the bacteria. The possible causative agents include parasitic ameba, known as Entamoeba histolytica as we all as salmonella and the most common shigella. An infection for E . histolytica is referred to as amoebiasis and can result in bloody diarrhea also called amoebic dysentery. Particular shigella bacillus (細菌) called shigellosis can trigger bacillary dysentery.) This amoebas group together to form cysts, and these cysts emerge from the body of human waste.
The E. histolytica ameba and the Shigella bacteria often grow in food and water contaminated by human feces. His bacteria can be carried on peoples hand after using the bathroom. Good hygiene practices reduce the risk of spreading infection.
Symptoms from dysentery range from mild to severe, mostly depending on the quality of the sanitation in their areas where the disease spread.
In developing countries, signs and systems of dysentery tend to be milder than in developing nations or tropical areas.
Mild symptoms include;
A slight stomach-ache
cramping – 下痢.
These typically appear from 1 -3 days following an infection, a and the patient may recover within the week.
Some Individuals may also develop lactose intolerance, which can last for a long time, occasionally years.
Symptoms of bacillary dysentery
Symptoms tend to occur within 1-3 days of infection. There is usually an ache and teacher, but no mucus or blood in waste, Diarrhea may be frequent to start off with.
Less commonly, 多分:
- Blood or mucus in feces
- Intense abdominal pain
しばしば, symptoms are so mild that a doctor’s visit is not required, and the problem resolves in a few days.
Symptoms of amoebic dysentery
A person with amoebic dysentery can have the following:
- Painful passing of stools
- Watery diarrhea, which may contain pus, 血液, and mucus.
- Intermittent constipation
- Fever and chills
- If ameba burrows through the intestinal wall, they can spread into the blood stream – infecting other organs.
- Ulcers can develop. These may bleed, causing blood in stools
Symptoms may persist for several weeks.
The ameba may continue living within the human host after symptoms have passed. The symptoms may come back when the person’s immune system is vulnerable.
Treatment diminishes the risk of the amoebae surviving.
The physician will ask the patient about signs and symptoms they are having can carry out a physical examination.
A stool sample may be recommended by the doctor if the patient has recently traveled to a tropical or developing location
If symptoms are critical, diagnostic imaging may be recommended. This could be an ultrasound scan or an endoscopy.
Laboratory results will expose whether the infection is due to Shigella or Entamoeba histolytica infection.
If treatment is necessary, then the options will depend on the test results. If a patient has diarrhea or vomiting, he or she should drink plenty of fluids to prevent dehydration.
If you are not able to drink liquids , or diarrhea and vomiting are profuse, intravenous (4) fluid replacement may be needed. The patient will be put on a drip and monitored.
Treatment for mild bacillary dysentery.
Mild bacillary dysentery, the kind frequently found in developed countries with high-grade sanitation, will normally resolve without treatment.
しかしながら, the patient should drink plenty of fluids
重症例では, antibiotics may be prescribed.
Treatment for amoebic dysentery
Amoebicidal medication used to treat Entamoeba histolytica. These drugs will be used to ensure that the ameba does not survive within the body when the symptoms are resolved.
Flagyl or metronidazole, is often utilized to treat dysentery. It treats both parasites and bacteria.
If the lab results are not clear, the patient may be given a combination of amoebicidal and antibiotic medications, depending on symptom severity.
Complications of dysentery are a few, but they can be severe.
脱水, frequent diarrhea and vomiting can quickly lead to dehydration in infants and young children; this can become life threatening
Liver abscess: If amoebae reached the liver, and an abscess can form there.
Postinfectious arthritis: Joint pain may occur following the infection,
溶血性尿毒症症候群: Shigella dysentery can cause the red blood cells to block the entrance to the kidneys, leading to anemia, low platelet count and kidney failure.
Patients can also risk seizures from infections.
Dysentery primarily is from poor hygiene.
To limit the risk of spreading the infection, people should regularly wash their hands with soap and hot water, particularly before and after using the bathroom and preparing food.
This can decrease the chance of spreading the Shigella infections and other types of diarrhea by up to 35 パーセント.
Other measures to take when the risk is higher, 例えば, when traveling, 含めます:
Only drink properly sourced water, such as bottled water. Water you can confirm is clean.
Be aware if the bottle is opened and how it is opened, and clean the top of the rim before drinking
Make sure food is fully cooked.
