At 8 am, a freshman boys from Guangdong University of the West University City campus dormitory jumped eight seriously injured, was rushed to hospital, as of press time last night, 11 o'clock, the boys still in hospital. It was suspected that the students jumping out of windows by hanging branches, and a few lines hastily left suicide note, between the lines showing suicidal tendencies. This is the place for two consecutive days school students jump from a building, at present, the specific circumstances of the police is under investigation.
Suspect jumped from the seventh floor
Yesterday evening, reporters rushed to the site, site of the incident in the University City campus of Guangdong University of the West eight dormitory, which is a 7 storey male dormitory building, the suspicion jumped from the 7th floor rooftop. This reporter saw several police were on the lawn of the hostel downstairs investigation, the reporter noticed that the roof of the dormitory was the police pull up the blockade. Lee students, according to a witness, said the incident occurred around 8 pm in the evening, he parked downstairs in the dormitory to see more police cars
entamoeba histolytica transmission

Abstract: Legionella exists in natural water and soil, it is a facultative intracellular parasite, can invade human alveolar macrophages and other macrophages, alveolar epithelial cells and the aquatic environment in and parasitic protozoa ( macrophages and amoeba is related to the two major host cell). In eukaryotic host cells, it destroys the transport vesicles, resulting in cavitation, preventing phagosome-lysosome fusion one, resulting in cell replication, and finally to complete the replication of intracellular bacteria escape from the host cells, leading to host cell death. In recent years, intracellular Legionella infection and virulence of Legionella much progress, this article summarized below.

Infectious or Entamoeba histolytica disease is caused by the amoeba cell Entamoeba histolytica. It may or may not be symptomatic, and can exist a few years of a person infected intestinal infection. It is estimated that the world is wide and led to 70,000 deaths each. Symptoms, when present, may range from mild diarrhea, dysentery with blood and mucus in the stool. Transfer the contents of a

When the symptoms is that it generally known as the invasive amebic disease, and occurs in the presence of two main forms. Invasion of intestinal lining leading to "amoebic dysentery" or "amoebic colitis." If it could spread through the body parasites reach the blood, the most frequently results in liver, it causes "amoebic liver abscess." When the symptoms do not exist, the individual is still infected vector can transmit other parasites through poor hygiene practices. When the symptoms can be similar at the start when the epidemic of bacillary dysentery amoeba not bacteriological in origin, and treatment of different, although the two can be transmitted to prevent the practice of good wholesome.
Transmission
Amoeba infectious diseases from unclean drinking water and food and feces are usually sent, but it may also indirectly through contact with dirty hands or transfer objects and anal oral contact.
Infection by parasites found in the stool was a form of resistance to the uptake of the structure of the cyst was spread. Amoeboid cells may also have the freedom to child nutrition or the formation of cysts that do not, but these leave the body quickly after death and is rarely the only source of new infections. Because amoebic diseases through contaminated food and water is sent, it is often endemic poverty in the world is more highly developed regions due to less waste disposal system and untreated water.
And water contact, for example, by washing or brushing your teeth in the water from a polluted water source or to swallow in such washing dishes, can lead to infection.
Amebic dysentery and "passengers of diarrhea" are often confused or "Montezuma's Revenge" in Mexico, due to the prevalence of the two in developing countries, but in fact the majority of travelers diarrhea is bacterial or viral in origin. Liver abscess may occur without the development of amebic dysentery earlier.
Prevention
To help prevent the amoeba spread of infectious diseases at home and around: washing hands thoroughly with soap and hot water at least 10 seconds after using the toilet or changing baby's diapers and before handling food.
Clean bathrooms and toilets regularly; pay special care and tap toilet seat.
Avoid sharing towels or face washing machine.
To help prevent infection: Avoid raw vegetables, when the local area, they may use human feces to be a fertilizer.
Boil water or treat with iodine tablets.
Nature of the disease
Most infected people, perhaps 90%, are asymptomatic, but the risk of the disease has the potential to make victims of Illinois. It consists of the World Health Organization estimates that about 70,000 people die every year worldwide.
Transmission installed in the tank sometimes lasting many years. Symptoms take from a few days to several weeks to develop and reflect their own, but usually it is about two to four weeks. Symptoms may range from mild diarrhea, dysentery with blood and mucus. Amoeboid blood cells from the invasion of the intestine lining. In about 10% of cases of amoeba cells spread in the body sent to the blood, and may move to other organs. This usually means that the blood from the liver as this is the first place to reach the intestine, but they can be almost anywhere in the results.
Height of the start time variable, and the average period of asymptomatic infection persisted in one year. It is the lack of symptoms or their reasoning intensity may change with factors such as the amoeba cell tension may be the host immune response, and the United bacteria and viruses.
Amoeboid cells in the life of asymptomatic infection by eating and digesting bacteria and food particles in the esophagus, part of the gastrointestinal tract. It is not usually linked with the intestine mucus as a protective layer of the esophagus ranks. When the amoeba cells and cells of the intestine Top contact disease. It uses bacteria to digest, including the substance of it and then hiding the same enzymes that destroy cell membranes and proteins. This process led to the infiltration of people and led to the first flask shape of digestion in the intestine ulcers. Entamoeba histolytica ingested by phagocytosis and destruction of cells and red blood cells are often seen inside. In particular a large number of Latin American granulomatous (in amoeboma known) may be formed in the walls of the colon as a lasting cellular response, and sometimes confused with cancer.
In theory, a viable cyst intake may lead to infection.
Diagnosis of human disease
Asymptomatic human infection by finding cysts shed in the stool is usually diagnosed. A variety of floating or sedimentation procedures have been developed cysts from fecal recovery, and the stain to help visualize the isolated cysts for the microscopic examination. Because cysts are not usually shed, minimum should be reviewed in three stools. In accordance with the symptoms of infection, active form (child nutrition) in fresh feces can often see. Serological tests exist and most individuals (whether the symptom) will test positive for the presence antibodies. Antibody levels are high in individuals with liver abscess. Serology became positive only about two weeks after infection. New developments include the amoeba found in the feces of the identified proteins appear amoeba DNA kit and the other in the feces. These tests are not in widespread use because of their cost.
Microscopy clearly remains the most common method of diagnosis in the world. However, it is not as sensitive or accurate as other tests in the diagnosis can be used. Distinction is important from a nonpathogenic E. histolytica intestinal protozoan cysts such as Entamoeba sp cysts by its appearance. E. histolytica cysts up to four nuclei, and symbiotic bacteria Entamoeba cysts with 8 nuclei. In addition, E. histolytica, endosome and it is often distorted, in the center is located in the backbone of Entamoeba spp. Finally, chromatoidal jagged body in E. histolytica from them, Entamoeba cysts were surrounded by bacteria. However, other species, Entamoeba dispar and E. moshkovskii is symbiotic animals, and can not be distinguished from E. histolytica under the microscope. E. dispar is much more common than E. histolytica which means that much of the world there are many incorrect diagnosis of E. histolytica infection occurred. World Health Organization recommends should not be treated separately microscopy diagnosis of infection, if they are asymptomatic, and no other reason to suspect infection is actually E. histolytica.
Relative frequency of disease
In older textbooks often been stated that 10% of the world's population infected with Entamoeba histolytica. It is now know of at least 90% of these infections due to E. dispar. However, this means that there are 50 million true E. histolytica infection each year and about seventy thousand molds, primarily from the liver abscess or other complication. Although often considered tropical parasites, (1875) reported the first case is actually in St Petersburg in Russia, near the Arctic Circle. Infection is more common in warmer regions, but this is due to poor hygiene and even parasitic cyst long-term survival in the warm wet conditions of the two.
Treatment
E. histolytica infection occurs in the intestines and (in people with symptoms) in the intestine and liver tissue. The results of two different drugs are needed off the body infection, one for each location. Or a related drug such as Metronidazole Tinidazole, Secnidazole or Ornidazole use of aggression destroyed the organization amebae. These were quickly absorbed into the bloodstream and are transported to the infected site. Because they are rapidly absorbed almost no residue in the intestine. Because most of the amebae remain in the intestine, when the Organization of the invasion, but also get rid of those who are important or patients will be developed in the spread of dangerous diseases other cases. Several drugs for the treatment of intestinal infections, the most effective are available, which shows that Paromomycin (also known as Humatin); Diloxanide Furoate (also known as Furamide) for the United States and Iodoquinol (also known as Yodoxin) for some other countries. Must be used for drug treatment organizations and lumenal infection, when the Paromomycin or Diloxanide Metronidazole is usually given first, followed. E. dispar does not require treatment, but many laboratories (to be developed even in the world) there is no facility to distinguish this from E. histolytica.
For amebic dysentery have to use multiple chunks from the start method,: Metronidazole times a week 500-750mg 5-10 days
Tinidazole 2g once a day for 3 days is the choice of metronidazole
In addition to the above, it should be the same or continuously provided one of the following luminal amebicides as an adjunctive therapy, the destruction of E. histolytica in the colon: Paromomycin times a week 500mg 10  
Diloxanide furoate times a week 500mg 10  
Iodoquinol times a week 650mg 20  
For the amoebic liver abscess: Metronidazole 400mg 10   times a week
Tinidazole 2g once a day, 6 days is the choice of metronidazole
After the general meeting must be given every Wednesday Diloxanide furoate 500mg above the other lumenal amebicides 10 days (or one)
Dose calculated by body weight for children, and pharmacists should be consulted to help.
Herbal Treatment
In Mexico, it is common to use herbal tincture chaparro amargo (Castela texana). 30 whereabouts were taken in a small glass of water first thing the morning and 30 before falling at the last day meals, seven days direct. After 7 days of vacation from treatment, it was restored for seven days. Some mild cramps may be felt; it is required which means that amoeboid cells dying and being expelled from the body. Many Mexicans use chaparro amargo treatment usually three times a year. Effectiveness of this treatment is not scientifically proven.
A 1998 study recommended that each week in Africa, 2 tablespoons of papaya seeds in the amoeba may have an infectious disease prevention and assistance antiamoebic action, but remain unconfirmed. Papaya fruit and seeds in the region is often considered beneficial for digestion, the plant is common.
Complex
In most cases, the amoeba cells remain in the host gastrointestinal tract. Severe esophageal mucosal surface in less than 16% of ulcer cases occur. In a few cases of parasite invasion of soft tissues, usually liver. Only rarely is the formation of large (amoebomas) that leads to intestinal obstruction.
With Entamoeba histolytica infection linked to malnutrition and hinder growth. [1]
Population at risk
All that is susceptible to no evidence of infection, and individuals with damaged immune or conduct disorders may suffer more severe forms.
Food Analysis
E. histolytica cysts from contaminated food may be restored by a method similar to those used for the recovery of Giardia lamblia cysts from feces. Filtration is probably the most practical approach to drinking water and liquid food from the remedy. E. histolytica cysts must be distinguished from other parasitic (but nonpathogenic) protozoa cysts and protozoan cysts from free survival as described above. Recovery process is not very accurate; cyst recognized easily lost or damaged beyond, to remedy the negative test results led to many errors. [2]
Outbreak
The United States is the most dramatic events of the outbreak in Chicago in 1933 the world market caused by the contaminated drinking water; defective water pipes allowed contaminated water. 1,000 cases (with 58 deaths). 1998 [outbreak] amebic infectious diseases in Georgia. One hundred and seventy-seven cases reported in May between the 26 September and 3 October 1998, including 71 cases of intestinal infectious disease and amebic liver abscess in 106 possible cases. Recently, a number of food managers are suspected of causing evacuation of infection.
