E. coli, an infection that struck Europe

Of E.coli , the infection that struck Europe
infected with E. coli E. coli vegetables have killed at least 19 people, 2.2 thousand. Considered victims.

Fresh cucumbers, tomatoes and lettuce were deadly poison for 19 people in Germany.In total, we have suffered more than two thousand fans of fresh vegetables from Sweden, Denmark, Austria, the UK and the Netherlands.

According to experts, an acute intestinal disease was caused by the bacterium Escherichia coli (E. coli), which had been infected with vegetables imported from Spain.

whether Spaniards blame - is hard to say, because trade between EU countries are so intertwined that the source and the spread of infection is very difficult to establish.

As it turned out, invisible to the naked eye E. coli E. coli not only causes serious diseases with a fatal outcome, but an international scandal with serious economic damage.

E. coli: a very useful

coli E. coli (Escherichia coli, Latin escherichia coli; standard abbreviations E. coli.) - Type of Gram-negative rod-shaped bacteria that are part of

the normal microflora of the human gastrointestinal tract.

It already appears in newborns and lives in the intestines of all human life, fulfilling very important functions.There are many varieties of E. coli, including more than 100 pathogens (ie disease-causing) types.E. coli inhibits the growth of harmful bacteria involved in the synthesis of vitamins B1, B2, B3, B5, B6, B9, B12;in cholesterol metabolism, bilirubin, choline, fatty acids and bile, it has an effect on the absorption of iron and calcium.

E. coli E. coli taken from the intestinal lumen oxygen is fatal to the beneficial bifidobacteria and lactobacilli.

... and very tenacious

E. coli more resistant in the environment compared to other Enterobacteriaceae, stored for a long time in the soil, water and faeces.But

and drying wand also well tolerated.It is able to multiply in foods, particularly in milk.Getting rid of it can be boiling or exposure to disinfectants (bleach, formaldehyde, phenol, mercuric chloride, sodium hydroxide, etc.).

Many Faces of E. coli

ehsherihioza - Infectious diseases accompanied by intoxication and fever.Pathogenic or pathogenic serotypes E. coli, "being in the wrong place," that is coming through the intestinal mucosa into the abdominal cavity (in violation of the integrity of the intestinal wall), bladder or blood - in those tissues and organs that are normally sterilecause diseases of these organs, or even sepsis.

Intestinal infections caused by E. coli

When a tourist from developed country gets in areas with unusual or poor sanitary conditions, to his external impressions are usually added to travelers' diarrhea - bacterial gastroenteritis caused by all of the same E. coli.

Infection with enterotoxigenic strains of E. coli usually occurs in the use of raw water and raw unwashed vegetables.

transmission mechanism - fecal-oral.The amount of agent must be sufficient to withstand the ravages of hydrochloric acid in the stomach.Full or partial absence of free hydrochloric acid in gastric juice - a condition called achlorhydria predisposes to disease.

As a result, increases the volume of fluid secreted by the intestine, and in a day or two after infection appear intestinal cramps and frequent rapid gastric emptying.Symptoms are held three to four days.

hospital outbreaks of gastroenteritis, according to the clinical picture is very similar to dysentery (fever, bloody diarrhea) cause enteropathogenic strains of E. coli.Enterohaemorrhagic E. coli strains are the cause of hemorrhagic colitis - severe bloody diarrhea.

urinary tract infections caused by E. coli

development of hemolytic uremic syndrome - the causes of acute renal failure in young children - provokes diarrhea caused by E. coli (70-85% of cases).The disease accompanied by a central nervous system until coma.

main agent of infection in the genitourinary system, called E. coli experts - it is responsible for almost 80% of community-acquired urinary tract infections and urinary organs.

Very often such an infection common in women, and infection occurs directly from the gastrointestinal tract with insufficient hygiene and because of the anatomical structure, as well as a consequence of the application of specific sexual practices.

about inflammation in the urinary tract, the bladder and kidneys, caused by E. coli bacteriuria is evidence - the presence of E. coli in urine.

abdominal infections caused by E. coli

E. coli is the most common cause of septic peritonitis.Penetrating into the abdominal cavity through the intestinal wall, causing coli E. The abdominal abscesses, cholecystitis (acute or chronic inflammatory disease of the gallbladder), including blackleg, which is characterized by a high incidence of complications and mortality.

Patients with diabetes and atherosclerosis are at greatest risk of such complications when infected with E. coli.


Once in the bloodstream, causing coli E. The most severe disease - septicemia, dangerous septic shock, in which the developing dysfunction of multiple organs and even in intensive care mortality rate is very high.

Another consequence of sepsis - multiple organ failure, in which the organ or system is so damaged that it is not able to maintain the livelihood of the body, leading to death.


modern industrial microbiology and biological engineering can not do without E. coli, for them it - magic wand, which science has an important role.

E. coli is considered a universal body for the synthesis of foreign proteins and the development of vaccines.Various specially selected strains of E. coli are part of some drugs.
