Super Bug Outbreak Alert! 8-19-2011

Scientists Search for Kryptonite to Defeat Drug-Resistant Super Bugs

Many Believe that a Supervirus will be the Doom of Mankind

This theory has been gaining more popularity lately, as many new drug-resistant superbugs have been not only been killing people, but birds, fish and even pigs across the globe.


With birds falling from the sky while people are dying in modern hospitals from mysterious staff infections, its no wonder that people's imaginations are running amok. While religious doomsday sayers preach about biblical plagues many heathen conspiracy theorists believe the diseases were manufactured in government labs to implement some sort of population reduction.

Meanwhile, public health officials are worried about the rising number of new drug resistant superbugs, as well as of the overuse of antibiotics, hand sanitizers and home disinfectants. The overuse of atibiotic drugs and cleaners could make these bacteria resistant to them, so that they would no longer work for even curing minor viral infections, including flu, coughs, colds and sore throats.  

Fortunately, a team of Canadian scientists discovered that specific mixtures of antimicrobial agents presented in lipid (fatty) mixtures can significantly boost the effectiveness of those agents to kill the resistant bacteria.

Thank God these "Super bugs," which can cause wide-spread disease and may be resistant to most, if not all, conventional antibiotics, still have their weaknesses.

According to Richard Epand, Ph.D. from the Department of Biochemistry and Biomedical Science at McMaster University in Hamilton, Ontario, Canada, a researcher involved in the study, "This study may contribute to overcoming the lethal effects of drug resistant bacteria that is becoming an increasing clinical problem, particularly in hospitals."

Their discovery came when Epand and colleagues conducted experiments using groups of mice infected with lethal doses of multidrug-resistant Escherichia coli (E. coli). The rresearchers then treated the mice with conventional drug combinations or drug combinations encapsulated in lipid mixtures. They found that certain lipid mixtures caused the drugs to act together in a synergistic manner. In this mano, the drugs were far more effective in increasing the survival rate of the lab rats, as they overcame the cellular mechanisms used by these bacteria to defeat therapeutic agents.

This study also demonstrated a new use of the premier family of antimicrobial agents called oligo-acyl-lysyls, which have the potential to be combined with other drugs to yield a platform for other specific applications.

Gerald Weissmann, M.D., Editor-in-Chief of The FASEB Journal said, "as we've seen in the recent E. coli outbreak in Germany, bacteria can mutate to become super bugs that resist antibiotics. Thanks to this new, lipid-based antibiotic therapy, multidrug-resistant bacteria may begin to look more like Jimmy Olsen and a lot less like Superman."...

What do you think? Do you think science will outsmart bacteria and viruses? Do you believe we will someday conquer disease? Maybe enable people to live longer? Please leave your comment bellow!

Superbug frightening for frail patients in Los Angeles, Utah and beyond

Published: Monday, March 28, 2011 12:25 p.m. MDT
 
A "superbug" that outsmarts multiple types of antibiotics in the medical arsenal has infected more than 350 patients in Los Angeles-area facilities. And that has health officials nationwide worried. A study of the issue by the LA. County Department of Public Health will be presented in Dallas next week at the annual meeting of the Society for Healthcare Epidemiology of America.
ABC News reported this weekend that carbapenem-resistant Klebsiella pneumoniae, or CRKP, had been seen hundreds of times there between June and December of 2010. Most of the patients were elderly. The report quoted study author Dr. Dawn Terashita, medical epidemiologist, as saying most of the patients were elderly, they were often on ventilators and they are apt to have been staying at a facility for a long time.
The Centers for Disease Control and Prevention began tracking CRKP across the country in 2009. Officials there say it is harder to treat than MRSA, methicillin-resistant Staphylococcus aureus. It has also been confirmed in most of the states, including Utah, according to a map made by the CDC.

The CDC describes Klebsiella as a type of gram-negative bacteria that normally is found living harmlessly in human intestines. It can cause a variety of infections, most of them associated with healthcare settings, including pneumonia, bloodstream infections, wound or surgery-site infections and meningitis. That's determined by how it enters a patient, so infection gained through respiration becomes pneumonia, while that in a wound becomes a bloodstream infection, for example.

So-called "superbugs" occur when bacteria mutate to the point that antibiotics previously effective against them no longer are. "Superbug" and "multiresistant" are sometimes used interchangeably.

The ABC report emphasizes that healthy people are not endangered by the bacteria, but said it can be lethal to those who are ill or frail....

Superbug outbreak declared at Kingston hospital

Aug 17, 2011 – 9:01 AM ET
KINGSTON, Ont. — An Ontario hospital has declared a facility-wide outbreak of the drug-resistant superbug C. difficile, after 12 new cases were reported in the last 30 days.

The Kingston General Hospital said in a statement that staff are working to contain the outbreak and stop further spread of the hospital-acquired infection.

The hospital is urging people not to come to the hospital if they are feeling unwell, and advising visitors to be diligent in washing their hands to prevent spreading the disease.

C. difficile spreads through contact with fecal matter and is especially difficult for the elderly and those with existing health conditions to handle. Symptoms include diarrhea, loss of appetite, nausea and abdominal pain.

Ontario has struggled to contain the superbug, which is responsible for at least 24 deaths since May.

Hospitals in the Niagara area, Guelph and Orangeville have all grappled with outbreaks.

Superbug alert after hospital patient dies

Mary Ann Benitez
Wednesday, August 17, 2011



Infection control measures were rushed in at a ward in Caritas Medical Centre after an elderly man with a hospital-acquired superbug infection died. 
Two other patients were found to be carriers of the superbug and were in fair condition in isolation last night.

The Kowloon hospital said a 74-year-old man with pneumonia and acute renal failure was admitted to a 50-bed medical ward at the hospital in Sham Shui Po on July 29.

The patient was put on a catheter, but there was no information on other treatment he received.

He was confirmed to be suffering from Vancomycin-resistant enterococci (VRE) urinary tract infection on Sunday.

He died of renal failure yesterday morning.

The case is being investigated by the Hospital Authority and the Centre for Health Protection.

The hospital is testing patients who stayed in the same ward with the man over the same period and have found two male patients aged 74 and 76 to be VRE carriers after rectal swabs.

Both men were earlier admitted to hospital for pneumonia.

"This is contact precaution," a hospital spokeswoman said. "They have no infection signs, just carriers."
Both patients are being monitored and are in fair condition in isolation.

The hospital has stepped up handwashing and alerted staff to keep to a high standard of disease control and ensure proper use of antibiotics, including Vancomycin, and management of VRE carriers.

Tests are pending on other patients who may have been infected, the spokeswoman said, adding that no members of hospital staff are being tested for the superbug infection.

A specialist in infectious diseases, Lo Wing-lok, said he is not surprised with the cluster of superbug infections.
This is because Caritas serves "a very aged area and there are so many elderly patients who are chronically ill and staying in hospital for a long time."

VRE is an opportunistic bacteria found in the intestines which usually preys on the elderly and patients with low levels of immunity.

Lo said a urinary catheter usually serves as "a highway for the bacteria to move from the bowels to the urinary tract."

Elderly men "have big prostate glands and do not pass water as well as young people" so are prone to urinary tract infection when they use catheters for too long.

"I understand how such outbreaks can happen where elderly patients are being admitted and stay for a long time, where it is usually crowded and staff are stretched to the limit. We can only blame the system," he said.

New superbug is on the rise in our hospitals

WORRY: More patients hit by CRE


By Clodagh Sheehy
Thursday August 18 2011

Four new cases of a hospital superbug, which can cause dangerous infections in vulnerable patients, have been detected here in the past month.

The bug, which is resistant to some antibiotics, can hit the kidneys, wounds and blood of patients.

The Health Protection Surveillance Centre (HPSC) is to review all critical care units to assess the prevalence of the infection.

The bug CRE (Carbapenem Resistant Enterobacteriaceae) lives in the bowel and five cases were detected in Irish hospitals earlier this year.

The independent European journal Eurosurveillance has now confirmed that "as of July 20, 2011 an additional four cases" of the superbug had been found.

The nine cases are the first reported cases of this strain of CRE in Ireland and the HPSC has described the outbreak as "dramatically changing the epidemiology of CRE in Ireland".

CRE cases have been notifiable in Ireland since March but to date there has been no national compulsory screening programme.

Five cases were detected between March and Junein patients who had all undergone complex stomach surgery.

COMPLICATIONS
One patient later died from "complications of a gastro- intestinal haemorrhage not related to infection".

The four new cases were found in St Vincent's hospital in Dublin and the Mid Western Regional hospital in Limerick, St John's Hospital, Ennis General Hospital and Nenagh General Hospital.

None of the patients had been treated at a healthcare facility outside the country in the previous 12 months and so had not picked up the bug abroad.

The superbug was first found in Turkey three years ago and since then outbreaks have been reported in France, Germany and the UK, Argentina, Lebanon, Israel Morocco and Tunisia.

The HPSC has announced plans for a new study to detect how common the bug is in hospital intensive care units in this country.

Is Swine Flu in Utah?

Questions and answers about swine flu in Utah
The Salt Lake Tribune

Updated: 04/28/2009 07:44:41 AM MDT

Utah has no confirmed or even suspected cases of swine flu as of Monday evening. But health officials, hospitals and others are preparing for possible cases. Here's what you need to know, from the Utah Department of Health and other responders.

How worried should I be about the swine flu breaking out in Utah?

Utahns should be highly alert for symptoms -- particularly if you have recently traveled to Mexico or had contact with someone who has -- but otherwise carry on with their normal lives. "What people don't acknowledge is we have deaths from seasonal influenza every year," said David Sundwall, executive director of the Utah Department of Health.

Is it inevitable that Utah will have cases?

It's "likely," Sundwall said, adding: "I'll be surprised if it doesn't show up here." In Idaho, four reports of people with flulike illnesses were being investigated Monday, according to the state Department of Health and Welfare. One person is from Fremont County, two are from Madison County, and the fourth is from Ada County.

Are the symptoms of swine flu different than the seasonal flu?

Not really. Symptoms of either flu may include fever, body aches, runny nose, sore throat or cough; some patients may also have nausea, vomiting or diarrhea. The U.S. Centers for Disease Control and Prevention has seen more severe diarrhea or vomiting, or both, in some cases of swine flu.

How do I avoid getting the flu?

Avoid close contact with people who are coughing or ill. Wash your hands frequently. If you're not sick, do not seek anti-viral medication from your doctor unless you have symptoms, the Utah Department of Health urges.

Will my seasonal flu shot protect me?

No.

What should I do if I feel ill?

» Stay home from work or school to avoid spreading the infection.

» Cover your cough with your shirt sleeve. Avoid touching your eyes, nose and mouth.

» Seek medical care for severe symptoms; clinicians will collect samples for testing at the Utah Public Health Laboratory.

Do Utah's hog farms make the states' residents more vulnerable to swine flu?

No, because people who have the virus generally have not had contact with pigs, said Tom Hudachko, state health department spokesman.

Leonard Blackham, Utah commissioner of Agriculture and Food, added there is no sign that Utah hogs are infected with the new flu, and a network of state and private veterinarians will continue to monitor the health of farm animals.

Because pigs can catch the flu from humans, he added, producers are being urged to keep ill employees away from animals.

The high rate of international travel to and from Utah may be a more problematic factor, Sundwall said.

Can I catch swine flu from eating pork?

No. Swine flu viruses are not transmitted by food. And cooking pork to an internal temperature of 160 degrees Fahrenheit kills viruses and foodborne pathogens, Blackham said.

What is Utah doing to prepare for possible cases?

» Acquiring about 60,000 doses of anti-viral medication from the Strategic National Stockpile, bringing Utah's arsenal up to more than 100,000. Tamiflu and Relenza appear to affect the symptoms of the swine flu virus.

» Health and hospital officials are urging prevention and planning care for possible swine flu patients, based on existing detailed pandemic flu plans.

» Infectious disease experts and other clinicians at Intermountain Medical Center, Utah's largest Trauma 1 center, met Monday morning to discuss how to respond to the nation's declaration of a public health emergency and to prepare for potential patients.

» As a precaution, patients coming to any Intermountain Healthcare hospitals in the Salt Lake Valley -- LDS Hospital, Alta View Hospital and The Orthopedic Specialty Hospital -- are being asked to wear a mask if they have respiratory illnesses or symptoms, including coughing. Visitors with such symptoms are being asked to stay away.

» University Hospital alerted staff to be on the look out for symptoms, but had not seen an influx of patients with apparent swine flu symptoms. MountainStar hospitals, including St. Mark's Hospital in Salt Lake City, also are preparing to treat possible swine flu patients and are isolating patients with infectious symptoms in the meantime.

Is Salt Lake City International Airport taking precautions?

Airport spokeswoman Barbara Gann said a "very small" number of Customs officials and airline agents in the International terminal are voluntarily wearing masks and gloves to protect themselves.

She said as of Sunday, Delta Airlines stopped its last nonstop flight to Mexico City, because of a seasonal lull in travel. The airport still has 14 weekly nonstop flights to San Jose, Puerto Vallarta and Cancun, Mexico. That is 1,700 seats each week, Gann said.

"Our exposure to direct Mexico flights is minimal," she said.

Is the outbreak having an affect on Utahns' travel plans?

Not yet. Morris Murdock Travel had only four cancellations Monday out of almost 1,000 people who had booked trips to Mexican resorts. A handful of customers switched destinations from Mexico to Hawaii or the Caribbean, said spokesman Jim Barsch. Mexico is the second largest source of foreign tourists to Utah, so industry officials are watching reports closely, but trying not to create a panic. Gov. Jon Huntsman Jr. has not altered plans for a May 11-14 trade mission to Israel.

Is the Church of Jesus Christ of Latter-day Saints taking any precautions for missionaries in Mexico? Are all missionaries well?

Missionaries are safe but church authorities have canceled all meetings until further notice. LDS leaders have also advised missionaries and members in Mexico City to follow basic sanitary precautions as a guard against infections. LDS Church records show 1,121,933 members in Mexico and 21 missions with between 75 and 150 missionaries each.

Where can I learn more?

The Centers for Disease Control and Prevention offer more information at www.cdc.gov/swineflu. Utah has developed its own site at health.utah.gov/epi/SwineFlu/.

Tribune reporters Julia Lyon, Jason Bergreen, Mike Gorrell and Peggy Fletcher Stack contributed to this report.

Death Toll Rises in Mexico

Mexico: suspected swine flu deaths climb to 149
April 27th, 2009 @ 11:02am

MEXICO CITY (AP) - Mexico's government is ordering closed schools nationwide as the suspected death toll from swine flu climbed to 149.

Health Secretary Jose Angel Cordova says only 20 of the deaths have been confirmed to be from swine flu and the government was awaiting tests results on the rest.

He says 1,995 people have been hospitalized with serious cases of pneumonia since the first case of swine flu was reported on April 13. The government does not yet know how many were swine flu.

Of those hospitalized, 1,070 have been released.

Cordova says school at all levels nationwide are suspended until May 6. Schools had already been suspended in Mexico City and five of Mexico's 32 states.

Understanding Swine Flu

Understanding Swine Flu Outbreak: Questions and Answers

By John Lauerman

April 27 (Bloomberg) -- Swine flu, a virus that normally infects pigs, has been detected in people in Mexico, the U.S., New Zealand, Canada, and the U.K. Health officials around the world are checking to see whether infections have occurred in their countries, and readying measures to prevent its spread.

Here are answers to some frequently asked questions about swine flu. The information is drawn from the data released by the World Health Organization in Geneva and the U.S. Centers for Disease Control and Prevention in Atlanta.

Q: What is swine flu? A: Influenza is a virus that infects people, birds, pigs and other animals such as ferrets. Swine flu, or swine influenza, is a form of the virus that normally infects pigs. There are many forms of flu, and the different varieties have the ability to exchange genes with one another. The form of flu that originated in Mexico is a genetic mixture of viruses that have been seen in pigs, birds and people. It’s being called a swine flu because the overall structure of the virus is of the type that affects pigs, said Keiji Fukuda, a WHO official.

Q: How do people catch swine flu? A: Studies are still ongoing on how this particular swine flu is transmitted. Flu is generally transmitted through the respiratory tract. Droplets of infected body fluids can carry flu when people cough or sneeze. Studies indicate that masks called N95 respirators that, when properly used, filter germs from the breath and hamper the spread of flu. Neither contact with pigs nor eating pork has been linked to the spread of the flu, Fukuda said today. Still, health researchers are working to establish that the virus is spreading from person-to-person.

Q: What are the symptoms of swine flu? A: About one to four days usually elapse between the time a person is infected and the onset of symptoms. Influenza normally causes symptoms such as coughing, sneezing, headaches and body aches, fever, chills, and sometimes vomiting and diarrhea. Swine flu causes the same symptoms, and may be difficult to distinguish from other strains of flu and respiratory illnesses. Severe cases of flu that lead to death are normally seen in very young and very old people whose immune systems are too weak to fight off the virus. Adults with severe illness may also have difficulty breathing, dizziness, confusion, or severe vomiting and diarrhea.

Q: How can I tell if my child is sick? A: Children who are breathing abnormally fast or slowly may have respiratory illness. Bluish skin indicates a need for quick attention. Children who are abnormally sluggish and sleepy, irritable, or have fever or rash may also need attention.

Q: Have there been outbreaks of swine flu before? A: Yes. Health officials said in 1976 that an outbreak of swine flu in people might lead to a pandemic. Widespread vaccination was carried out in the U.S. before experts determined that the virus was not dangerous enough to cause a pandemic. Swine flu occasionally infects people in the U.S. without causing large outbreaks. From 2005 through January 2009, there were 12 reported swine flu cases in the U.S. None of them caused deaths.

Q: Why are health officials concerned about the outbreak of swine flu? A: When flu viruses mix their genes with one another, they can take on new forms. New flu viruses are harder for the immune system to defend against. With little or no opposition from the immune system, they can grow quickly and invade many tissues and organs. They may also set off a harmful immune overreaction in the body, called a “cytokine storm,” that may be lethal in itself. The swine flu virus from Mexico may have the ability to spread quickly and kill people, possibly causing a worldwide pandemic, according to the World Health Organization. Researchers are conducting studies right now to determine how easily the virus spreads in people and how dangerous it is.

Q: What’s a flu pandemic? A: Flu pandemics occur when new influenza viruses emerge that spread quickly and few people have immunity to them. While influenza viruses were only discovered about a century ago, researchers believe flu pandemics hit about twice or three times each century. Some pandemics are relatively mild, killing just a few million people globally. The most severe flu pandemic on record was the 1918 Spanish Flu, and researchers estimate it killed about 50 million people around the world.

Q: Are there any similarities between the swine flu and earlier pandemic viruses? A: Flu viruses are classified by two proteins on their surface, called H for hemagglutinin and N for neuraminidase. Both the swine flu found in Mexico and the 1918 Spanish Flu viruses are of the H1N1 subtype. Both viruses appear to have originated in animals; researchers believe the Spanish flu spread to people from birds. The two viruses are not identical, and there are still many genetic differences between them that researchers are studying.

Q: Do all H1N1 viruses cause pandemics? A: Not all H1N1 viruses cause pandemics. H1N1 descendants of the Spanish Flu virus continue to circulate in people and sometimes cause outbreaks of seasonal flu.

Q: Is there a vaccine against the swine flu from Mexico? A: Flu vaccines generally contain a dead or weakened form of a circulating virus. The vaccine prepares the body’s immune system to fend off a true infection. For the vaccine to work, it must match the circulating, “wild-type” virus relatively closely. There is no vaccine currently that exactly matches the swine flu. However, if the virus is sufficiently similar to circulating forms of H1N1 flu that are included in current vaccines, they may offer some limited protection from swine flu. While U.S. health officials are investigating this, the possibilities for this protection are poor, they said yesterday on a telephone call.

In addition, millions of people in the U.S. were vaccinated against swine flu in 1976. While that was not the same strain of flu as the one from Mexico, people who got the 1976 vaccine may get some limited protection from the currently circulating virus. Health officials may do some research on this issue as well.

Vaccine makers have contacted the World Health Organization about obtaining samples of the virus needed to make a vaccine. Making flu vaccine can take three to six months, depending on the type of manufacturing used.

Q: Are there drugs that treat swine flu? A: Roche Holding AG’s Tamiflu and GlaxoSmithKline Plc’s Relenza both have activity against swine flu. The U.S. has released its stockpile of Tamiflu to treat people with swine flu. Flu viruses sometimes develop resistance to antiviral drugs. The human form of H1N1 that’s currently circulating is resistant to Roche’s Tamiflu (not Relenza). If the two viruses were to exchange genes, the swine flu might become resistant, too.

Q: How else can I protect myself from swine flu? A: Personal hygiene measures, such as avoiding people who are coughing or sneezing and frequent hand-washing, may prevent flu infection. Those who aren’t health professionals should avoid contact with sick people, or those who are coughing or sneezing. People who get sick with flu symptoms should stay home. Studies have suggested that closing schools, theaters, and canceling gatherings in the early stages of a pandemic can limit its spread. Such measures would likely take place if health officials determine that the virus is spreading quickly enough and is deadly enough to cause a pandemic.
