There are numerous ways of being exposed to E. coli. Recoveryfrom such infections usually takes a week in adults, but when they occur in childrenthey may lead to a life threatening medical condition which affects the kidneysand is medicinally referred to as hemolytic uremic syndrome.

Escherichia coli causes

The nasty type of E. coli strain described above actuallyproduces a very toxic substance which causes significant damage to the liningof the small intestine and in most cases it leads to the onset of a bloodydiarrhea. Among the most common causes of such infections is exposure tocontaminated water, contaminated food and person to person contact. Animal and human feces may easily pollutesurface and ground water such as lakes, rivers, streams and water commonly usedfor the irrigation of the crops. The public water systems commonly utilizeozone, ultraviolet light and chlorine in order to kill all the harmfulbacteria, but in spite of that there have been certain outbreaks which were associatedwith contaminated municipal water supplies. Private wells may also beassociated with similar problems. Sometimes a person may also get infectedafter swimming in lakes or pools which have been contaminated with animal orhuman feces. E.coli infections are commonly acquired by consuming foods whichwere contaminated with the bacteria. Those foods usually include restaurantmeals, fresh produce, unpasteurized milk or ground beef. Restaurant meals caneasily be contaminated by the bacteria because of servers or cooks who do notwash their hand after using the bathroom. Fresh produce such as lettuce orspinach are very vulnerable to contamination of fields by the runoff fromcattle farms. This harmful bacterium caneasily travel from person to person, especially in the cases when persons donot wash their hands properly. Children are usually at the biggest risk ofacquiring an E. coli infection. There are various risk factors which may causesome people to be more likely to develop problems than some others, even thoughthe infection may occur in anyone who gets exposed to the bacteria. Eating certaintypes of food items such as soft cheeses made from raw milk, cider, applejuice, unpasteurized milk and undercooked hamburgers greatly increases the riskof acquiring E. coli infections. Those who have a weakened immune system are atan increased risk of acquiring an E. coli infection as well. These people areusually those who have AIDS or are under the effects of drugs commonly used forthe treatment of cancers or the prevention of the rejection of organtransplants. Age is another important risk fact. Older adults and youngchildren are at an increased risk of becoming ill with E. coli infections andalso acquiring some serious complications commonly associated with this type ofinfection.
