Is E. coli in water harmful? How to improve the excessive E. coli in the water?

Diseases caused by E. coli:

1. Extraintestinal infection.

Most of them are endogenous ** infections, mainly urinary tract infections, such as urethritis, cystitis, and pyelonephritis. It can also cause peritonitis, cholecystitis, appendicitis, etc. In infants, the elderly, the frail, chronic wasting disease, and patients with extensive burns, E. coli can invade the bloodstream and cause sepsis.

Premature infants, especially those born within the first 30 days of life, are susceptible to E. coli meningitis;

2. Acute diarrhea. Some serotypes of E. coli can cause diarrhea in humans. Among them, enterotoxigenic E. coli can cause diarrhea in infants and young children, with mild watery diarrhea and severe cholera-like symptoms.

Diarrhea is often self-limiting, generally cured in 2 to 3 days, malnutrition can be up to several weeks, and it can also be reversed. Enteropathogenic Escherichia coli is the main pathogen of infant diarrhea, which is highly contagious and can be fatal in severe cases. After the bacteria invade the intestine, they multiply mainly in the duodenum, jejunum, and upper ileum.

In addition, enterohaemorrhagic E. coli can cause sporadic or fulminant hemorrhagic colitis, which can produce Shigella toxin-like cytotoxins.

Mode of transmission: The disease can be transmitted by drinking contaminated water or eating undercooked food, especially beef immediate, hamburger steak and roast beef. Cases of infection from drinking or consuming unpasteurised milk, cheese, vegetables, fruit juices and yoghurt have also been detected. In addition, poor personal hygiene may also lead to infection through human-to-human transmission or through consumption of faecally contaminated food.

If the E. coli in the water exceeds the standard, how to deal with it to effectively kill the coliform bacteria? As the last barrier in the water treatment process, the disinfection process is mainly used to kill pathogenic microorganisms and ensure the safety of water quality. In order to prevent the occurrence and epidemic of water-borne infectious diseases and ensure human health, drinking water must be disinfected before it can be consumed.

Hydrogen peroxide silver ion composite disinfection products are the best products for water disinfection, and hydrogen peroxide silver ion composite disinfectants can replace chlorine-containing disinfectants, just as hydrogen peroxide pre-oxidation can replace chlorine-containing products for pre-chlorination, which has the significance of scientific and technological research. After hydrogen peroxide pre-oxidation, and then injected with hydrogen peroxide silver ion composite disinfectant, because of its high removal of organic pollutants and ammonia nitrogen in the source water, coupled with blocking the addition of free chlorine, the formation of carcinogen chloroform is eliminated from the root, so as to relieve the hidden concern of drinking water to human injury, and further improve.

If the E. coli in domestic water exceeds the standard, it cannot be used directly. Because E. coli is very harmful to the elderly, children and people with weak constitution. Even if it is boiled, it is best not to eat it.

If there is really no way, it is necessary to drink the infected water, which should be sterilized at high temperature, or under the guidance of professionals, it should be sterilized, filtered, and treated before use.

Answer: Escherichia coli, commonly known as Escherichia coli, was discovered by Theodor Escherich in 1885, widely distributed in nature, most of them are non-pathogenic, mainly epiphytic in the intestines of humans or animals, for normal flora, a small number of E. coli are toxic and can cause diseases.

It is not easy to eliminate E. coli in well water, because it is impossible to eliminate E. coli in and near the well because of its widespread existence.

If the water in the well is only for drinking, it can be boiled after each fetch to destroy E. coli in the water. Disinfectants can also be added to the well, such as sodium hypochlorite, calcium hypochlorite, etc., which can reduce the total number of E. coli, but it is impossible to completely eliminate them, and disinfectants should be added regularly every once in a while.

If the E. coli in the group is exceeded, the water should be disinfected to the large intestine, and the water can be heated at the same time, so the E. coli can be mixed with some alcohol.

Summary. Escherichia coli, also known as Escherichia coli, is part of the normal intestinal flora and is harmful to the following ways:

The first can cause extraintestinal infections, such as urethritis, cystitis, peritonitis, bloodstream infections and other infections. When these infections occur, they should be examined in the hospital in time, take corresponding specimens, isolate and culture bacteria, and conduct drug susceptibility tests, and select effective antibiotics for ** and treatment according to the results of the drug to eliminate the infection caused by E. coli in the body.

Second, because E. coli can be divided into 6 different types of Escherichia coli, such as intestinal pathogenicity and intestinal invasiveness, it can cause severe diarrhea, lead to loss of electrolytes, nausea, abdominal pain, etc., and should be treated in a timely manner, supplemented with electrolytes, infusions, and the application of appropriate antibiotics.

Harm of E. coli to the human body.

Escherichia coli, also known as Escherichia coli, is part of the normal intestinal flora, and the harm is as follows: First, it can cause infections outside the intestine, such as urethritis, cystitis, peritonitis, bloodstream infections and other infections. When these infections occur, they should be examined in the hospital in time, take corresponding specimens, isolate and culture bacteria, and conduct drug susceptibility tests, and select effective antibiotics for ** and treatment according to the results of the drug to eliminate the infection caused by E. coli in the body.

Second, because E. coli can be divided into 6 different types of Escherichia coli, such as intestinal pathogenicity and intestinal invasiveness, it can cause severe diarrhea, lead to loss of electrolytes, nausea, abdominal pain, etc., and should be treated in a timely manner, supplemented with electrolytes, infusions, and the application of appropriate antibiotics.

Can an E. coli infection heal on its own.

E. coli infections may or may not resolve on their own, depending on the severity of the condition.

Is there any medicine that can be used**.

Escherichia coli is a conditionally pathogenic bacteria in the intestine, which can cause infections inside and outside the intestine under certain conditions, and infection can be controlled with antibiotics. What medicine to use should consult the advice of a professional doctor, do a drug susceptibility test through blood, urine, feces, etc., and choose a sensitive antibiotic according to the test results. Do not self-medicate or increase the dosage without authorization, so as to avoid other discomforts caused by irrational medication.

E. coli is transmitted in three ways: first, through food, second, through water, and third, through close contact. E. coli is transmitted in three ways: first, through food, second, through water, and third, through close contact.

You are very long-winded.

This is a network issue that caused the error.

I know I can't get a result.

The detailed questions must be found out by going to the hospital for examination, and the doctor will give you advice according to your situation. This kind of problem related to physical health is better to go to the hospital for consultation, which is more secure.

1. Enteropathogenic Escherichia coli, causing watery or egg drop soup stool in infants and young children;

2. Enterotogenic Escherichia coli, most patients have no obvious abdominal pain, and have more than a dozen watery stools a day;

3. Enteroinvasive E. coli, causing fever, abdominal pain, diarrhea, mucus and blood in the feces;

4. Enterohemorrhagic E. coli, the patient has watery stool in the early stage, and then bloody stool;

5. Intestinal agglomeration of Escherichia coli is related to intractable diarrhea in children.

Escherichia coli mainly epiphytes in the intestinal tract of humans or animals, and most of them not only do not cause harm to the body, but can inhibit the reproduction of intestinal pathogens and other pathogens. Some types of E. coli can cause symptoms such as diarrhea and hemorrhagic colitis, and are collectively known as pathogenic E. coli.

Legal Analysis: 1 Total number of bacteria in 1 ml of water does not exceed 100.

2 Number of E. coli in 1 l water, no more than 3.

3 If the source water is only chlorinated and used as water for domestic drinking, the average number of coliform bacteria shall not exceed 1000 per litre; The average number of coliform bacteria per liter of the source water used for drinking water after purification and chlorination shall not exceed 10,000.
