Potentially Deadly Superbug Rising In Chicago Hospitals
Overview of hospitals and clinics in the Chicago area in the U.S. showed a 30 percent increase in reported infections between 2009 and 2010, potentially dangerous groups of bacteria that are resistant to commonly used antibiotics.
KPC-bacteria were first identified on the U.S. east coast in 1999, since when they were gradually making their way across the country.
Researchers at Rush University Medical Center in Chicago and Cook County Department of Public Health, which conducted a survey-area medical institutions of Chicago, said that the incidence of KPC-growing bacteria.
They presented their findings on Friday 22 October, 48 th annual meeting of the Infectious Diseases Society of America in Vancouver.
Although the number of infections remain low, soaring still worried, given that determined if the first was Chicago in December 2007, researchers say.
PDA stands for Klebsiella pneumonia carbapenemase, an enzyme produced by the options common Klebsiella pneumonia bacteria that live on the skin in the mouth and the courage of people and can lead to pneumonia and urinary tract infections.
Dr Mary Hayden, director of clinical microbiology and associate professor of infectious diseases and pathology at Rush University Medical Center, told the press that:
"KPC-bacteria are a common type of bacterium that has become a dangerous source of infection and the main challenge for infection control."
"Infections caused by these bacteria are difficult to treat because most strains are resistant to most of our conventional antibiotics," she added, pointing to the alarming fact that "some strains resistant to all drugs, including those that are used when all other treatments fail.
"Because antibiotics are virtually ineffective against these bacteria, prevention is key," said Hayden, explaining that the infection is often associated with high mortality. She noted a study in which researchers found patients infected with the KPC-positive bacteria are three times more likely to die as patients infected with similar bacteria that do not offer the KPC.
In their survey, Hayden and his colleagues found that between 2009 and 2010 the number of medical institutions in Chicago, who reported KPC-infection of bacteria increased from 26 from 54 to 37 of 57, an increase of 30 percent, and average number of patients who tested positive for Superbug at each facility is nearly three times from 3,8 to 10,2.
They also found that three-quarters or more of patients were found to Superbug in a nursing home or other long-term care facility.
Hayden said the way to control the spread of Superbug is the coordination between long-term care facilities and acute-care hospitals, as patients infected with it are often transferred between them. Contact isolation is key to stopping the spread of bacteria.
As soon as he gets support, Superbug could spread rapidly to other parts of the geographic region. It took only a few years for a major outbreak occur in Israel after the first case was identified.
According to the U.S. Centers for Disease Control and Prevention (CDC), Klebsiella can be spread through contact person to person and from patient to patient on the hands of health professionals: it is suspended in the air.
Bacteria must get into the respiratory tract to cause pneumonia or blood cause blood infections. Hospital patients may get infected when they are on ventilators or intravenous catheter or wound (due to trauma or surgery).
Klebsiella rarely infects healthy people.
