Escherichia Coli are harmless can benefit humans by producing vitamin K2, or by preventing other bacteria in the gut.E coli is widely used in genetic engineering technology. Usually used as vectors to insert specific genes are desired to be developed. Escherichia Coli was chosen because it grows very fast and easy handling. Countries in Europe are now very wary of the spread of the bacteria E coli , they even forbid import of vegetables from outside Europe
Europe is currently facing outbreaks of Escherichia Coli bacteria which make the pain more than 1,600 people in Germany and killed 18 people. World Health Organization states, the pathogen causing this outbreak is a new strain that has never been known by scientists.
According to the Beijing Genomics Institute, China in cooperation with German scientists, strains of E. coli is a type of highly deadly and contagious. "This is a unique strain that has not been isolated from a patient before," said Hilde Kruse, food safety experts from the World Health Organization (WHO).
Preliminary research on the genetic analysis showed that this bacterial strain is a mutant form of the two bacteria E coli, Enteroaggregative E. coli (EAEC) and enterohemorrhagic E. coli (EHEC). When both bacteria are joined, would be harmful to humans.
"One of the bacteria will take toxic substances from other bacteria and produce toxins are more dangerous because it causes severe diarrhea, even damage tissue, including kidney," said Dr Paul Wigley, a biologist from the University of Liverpool, as reported by the BBC.
An Escherichia Coli outbreak case this has led to kidney failure is rare and life-threatening. Actually, the normal Escherichia Coli infections are also life-threatening, but generally only in the group of infants and children and people of low body resistance.
In the case in Europe is the most casualties are women and teenagers. The German government found 470 cases of kidney complications. This outbreak is feared more casualties because until now cannot ascertain the source of transmission of plague.
The incubation period of disease was three to eight days. E coli bacteria found in feces and can spread if a person has less clean living habits, such as not washing hands with soap.
Suspected outbreaks are caused by the initial raw vegetables contaminated with E coli. Several studies conducted in Europe also showed a strong association between symptoms of the disease and the consumption of raw vegetables.
WHO said the cases due to E. coli have been reported in nine European countries, including Austria, Denmark, Germany, Netherlands, Norway, Spain, Sweden, Switzerland, and England. The majority of cases of people in Germany or the people who've been traveling to northern Germany.
Outbreaks of Escherichia Coli that occurred in Europe are the third largest event and the cause of most fatalities. Earlier two people reportedly died in an outbreak in Japan in 1996 and made 9,000 people sick. Meanwhile, in 2000 in Canada reported 7 people died from E coli outbreak.
To avoid the dangers of Escherichia Coli or E Coli, should refer to process food guide below:
- Note the appearance, smell and taste of food and drink before going into the body.
- Wash food thoroughly. Rub entire surface with a soft.
- Wash hands, furniture, and kitchen utensils with soap and warm water before use.
- Separate raw food from ready meals.
- Cook food cooked with a minimum temperature of 71 degrees centigrade.
- Store food with good storage techniques in the refrigerator.
- Avoid juices, dairy products, and unpasteurized apple drink.
- Avoid consumption of beverages from water sources polluted.
