LA CROSSE, WI (WXOW)—Despite the news of Carbapenem-Resistant Enterobacteriaceae,CRE, a drug resistant bacteria, Gundersen Lutheran said they haven't had any cases locally.
But it has found some drug resistant bacteria in the same family.
CRE has been spreading over the past decade.
It's resistant to the strongest antibiotics and it can kill up to half of patients who get it.
Dr. David McNamara said part of the problem is pharmaceutical companies haven't been developing many new antibiotics.
"There aren't a lot of incentives for pharmaceutical companies to do that because it tends to be a less profitable area of pharmaceuticals than some other areas," Dr. McNamara said.
To solve the problem, Dr. McNamara said we need to use antibiotics carefully, make sure local hospital labs can identify CRE and practice superb infection control to prevent spread of bacteria from patient to patient.
Right now, these infections are limited to hospitals, but we know from history that bacteria that start in hospitals often find a way out into the community," said ABC News chief health and medical editor Dr. Richard Besser, who for seven years ran a CDC program aimed at promoting proper antibiotic use to curb antibiotic resistance. "That would be a nightmare scenario."
One in 25 acute-care facilities reported at least one case of hospital-acquired CRE last year, according to the CDC. Most of the infected patients, who tended to have multiple medical problems and weakened immune systems, were treated with colistin, an older antibiotic that can have toxic effects on the kidneys.
"For many patients, that's their only choice," Besser said. "And even with treatment, almost half of all patients who get this infection in their bloodstream die from it."
The CDC has urged hospitals, health care providers and patients to take steps to curb the spread of the dangerous superbug that include frequent hand-washing. The agency also recommends removing intravenous lines and catheters as early as possible to reduce the risk of infection.
"The goal of the campaign is to get this under control right now, before CRE has a chance to spread to more hospitals and out into the community," said Besser.
CRE isn't the only scary superbug. ABC News asked infectious disease experts which antibiotic-resistant bacteria pose the biggest threats at home and abroad.
The Original Superbug: Staphylococcus Aureus
Almost everyone's heard of MRSA, or methicillin-resistant Staphylococcus aureus. But few people understand just how pervasive the original superbug has become.
Roughly one in 50 people carries a strain of staph resistant to common antibiotics, according to the National Institutes of Health. If the bug invades a wound, it can cause an infection that's minor and localized, as in a pimple, or serious and widespread, involving the heart, lungs, blood and bones.
"MRSA continues to be the biggest threat because it could become more widespread," said Dr. William Schaffner, chairman of prevention at Vanderbilt University Medical Center in Nashville, Tenn.
MRSA infections usually strike elderly hospital inpatients or nursing home residents. But the number of MRSA cases out in the community is on the rise, according to the NIH. It can spread between people working out at the gym through contaminated towels or equipment, and has even been passed between children at day care facilities.
The Hospital Lurkers: Clostridium Difficile and Acinetobacter
Doctors have long been battling a group of six hospital-borne pathogens dubbed ESKAPE: Enterococcus, Staphylococcus, Klebsiella, Acinetobacter, Pseudomonas and Enterobacter. Now those six bugs are escaping antibiotics.
"These organisms were present in hospitals 20 years ago," said Dr. John Bartlett, chief of infectious diseases at Johns Hopkins University School of Medicine in Baltimore. "Now we've used so many antibiotics to treat them, they've been trained to become resistant."
The bacteria invade vulnerable bodies through hospital equipment, like surgical implants and central lines.
"When people come into the hospital, they often get metal put in them, or plastic lines. All of those foreign bodies [make someone] susceptible to infection," said Bartlett. "We can't help it. It's nobody's fault."
The Food Borne Bugs: Escherichia Coli and Salmonella
The bacteria behind food poisoning are becoming drug resistant, partly because farm animals are fed antibiotics to promote growth.
"Eighty percent of antibiotics in the U.S. are given to animals, not people," said Bartlett. "Now we're tracing some of these antibiotic resistant infections back to the farm."
In 2012, the U.S. Centers for Disease Control and Prevention reported that drug-resistant strains of E. coli causing urinary tract infections in women could be traced back to chickens fed antibiotics.
"E. coli is the most common cause of simple urinary tract infections, which we can very quickly and easily today. But as it becomes resistant, what was once simple [to treat] will become complicated," said Schaffner.
The European Union has banned antibiotics as growth-promoters. But the U.S. continues to lag behind, only last year restricting the use of antibiotics called cephalosporins in livestock.
"Quite frankly, I think that's embarrassing," said Bartlett. "Nobody's talking about the U.S. being very aggressive or successful in dealing with this problem."
The Sexually-Transmitted Infections: Gonorrhea and Chlamydia
Super gonorrhea may sound funny, but it's no joke. Antibiotic resistance means sexually-transmitted infections once cured with a few pills could require treatments that are more invasive.
"We might have to rely on intravenous or intramuscular treatments, meaning the patient would have to come in or someone would have to go to their home," said Schaffner. "These people don't want to be recognized in their home environment as having one of these infections, which a visit would kind of announce. So people will begin avoiding treatment. You have a spiraling series of problems."
The Global Threat: Tuberculosis
Tuberculosis kills 1.34 million people each year worldwide. And now the disease, once curable with antibiotics, is becoming resistant to multiple drugs.
"Among the world's 12 million cases of tuberculosis in 2010, WHO estimates that 650,000 involved multidrug-resistant TB strains," said Dr. Margaret Chan, director general of the World Health Organization.
Chan added that treating multidrug-resistant TB is extremely complicated, "typically requiring two years of medication with toxic and expensive medicines, some of which are in constant short supply. Even with the best of care, only slightly more than 50 percent of these patients will be cured," she said.
Although most cases of multidrug resistant TB are in developing countries, there were 92 U.S. cases reported in 2011, according to WHO data.
"We live in a very small world today," said Schaffner, explaining how travelers can import antibiotic resistant bacteria from developing countries. "It's a very small word and the bacteria do not need passports."
