children between four and 12 years of age have all tested positive for the
same Escherichia coli O157:H7 bacteria. Officials are still unclear as
to the connection and source of the outbreak. The children live or have
visited the Evergreen area of Denver,
but they do not attend the same school. Two children remain
State and County health officials are investigating deer or elk droppings,
along with other behaviors in the area where the children might have all come
in contact. The first case was reported in July and the last case was
reported late last month on October 22, health officials said.
E. coli are a group of bacteria found in animal intestines and feces.
While some E. coli strains are necessary for digestion; some are harmful,
deadly, and toxin-producing and part of a group of E. coli called Verocytotoxigenic E. coli, or VTECs,
also known as Shiga-producing E. coli. Of particular concern is the
virulent, sometimes deadly E. coli O157:H7 strain that is part of this group
and that is generally found to be the culprit in E. coli-related food-borne
illness outbreak. Strain O157:H7 has been confirmed to be to blame in
this outbreak in Colorado and is also to
blame for a variety of other outbreaks occurring in North
E. coli may cause fatal blood poisoning, cystitis, deadly septicemia, and
death. In the US,
E. coli is the leading cause of food-borne illness, sickening about 73,000
and killing 61; last year, over 22 million pounds of beef and vegetables were
recalled due to E. coli outbreaks.
A diarrheal illness caused by several types of bacteria, E. coli is spread
most easily when people eat or drink food or water contaminated with human or
animal feces or from infected symptomatic individuals. Initial symptoms
include sudden onset of watery, often bloody, diarrhea; abdominal cramping;
and, occasionally, vomiting. One-third of infected people develop
More and more, E. coli is turning up in produce and water and seems to be
sweeping North America in recent months with outbreaks popping up in a
variety of states in the U.S.
as well as in Canada.
E. coli taints meat through improper butchering and processing practices and,
once released in the body, produces a type of toxin that has been associated
with kidney damage in young children, and can also lead to kidney failure and
death. Infections generally last between five and 10 days and are
usually not treated with antibiotics because antibiotics can increase the
risk of more severe symptoms, such as hemolytic uremic syndrome (HUS), which
can result in acute kidney failure. Experts suggest hand washing,
especially after using the bathroom and those people suffering from nausea,
vomiting, diarrhea, or any other stomach ailment should drink plenty of water
or other liquids with electrolytes and should not prepare food for others.
There is growing concern in the scientific community—not just because of the
seeming prevalence of all manner of foodborne
illnesses—but because instances of drug resistant E. coli are being reported
world-wide and are similar in path to a mutated staph called MRSA, Methicillin-resistant Staphylococcus aureus
that, when not treated early, is resistant to all but the one antibiotic of
