MOLECULAR BASIS OF SPIRITUALITY SCIENCE


MOLECULAR BASIS OF SPIRITUALITY SCIENCE

MOLECULAR BASIS OF SPIRITUALITY SCIENCE – IMMUNOLOGY PROVIDES UNDERSTANDING OF SELF AND NON-SELF. PROTEIN MOLECULES CALLED ANTIGENS ELICIT IMMUNE RESPONSE.

To account for human existence, to face challenges to human survival, man has to identify molecules that operate various living functions. Man defends his life deploying protein molecules that recognize and respond to invasion of human body by pathogens consisting of foreign protein molecules. While learned experience provides cortical awareness of human immunological responses to attacks by pathogens, human mind is blissfully unaware of presence of pathogens. Recognition of non-self proteins and molecules called antigens is not a mental function. If Spirit or Soul functions as guiding mechanism, Spirit or Soul will have awareness of invasion of body by foreign antigens and body’s immunological response to such invasion. If Reticular Formation of Brain Stem, the site at which contents of Consciousness are composed, is viewed as seat of human Spirit or Soul, it has awareness of body’s invasion and response to attacks by pathogens. Immunological responses to infections trigger a stress response mediated by Hypothalamus – Pituitary – Adrenal Cortex Pathway.

The discovery of antibiotic-resistant Superbugs may eventually lead to better understanding of Spirit or Soul in shaping human survival while warding off invasion by pathogens.

Behind the scenes of a U.S. superbug discovery that made headlines around the world

Molecular Basis of Spirituality Science. Immunology provides the understanding of Self and Non-Self and the distinction demands recognition of Protein Molecules. Superbugs are antibiotic-resistant and pose challenge to human existence.

The Post’s Lena Sun visited Walter Reed Army Institute of Research in Silver Spring, Md., where scientists identified a strain of bacteria resistant to the last-resort antibiotic, Colistin.

 Microbiologist Patrick McGann knew he had identified a dangerous germ. He just didn’t know how dangerous.
In mid-May, a colleague had found a strain of E. coli bacteria from a 49-year-old Pennsylvania woman that tested positive for resistance to a drug called colistin. That’s the antibiotic used when all others fail.

McGann, whose job is to prevent outbreaks of new pathogens in the U.S. military’s sprawling health-care system, wasn’t yet alarmed. Sometimes mutations occur spontaneously that make bacteria resistant to an antibiotic. It would be a completely different problem, though, if the bacteria turned out to carry a certain ­colistin-resistant gene called mcr-1.

But that required deeper molecular testing. McGann asked his research team at the Walter Reed Army Institute of Research in Silver Spring, Md., to do an initial test for the presence of the resistant gene. And on May 18, he got the result as he rode Metro’s Red Line back to the lab from a meeting.

Research technician Ana Ong texted him to say the strain of E. coli had tested positive for the mcr-1 gene.
Stunned, McGann texted back: “You’re s—-ing me??” And then, realizing what the discovery meant, he didn’t wait for her reply.
“Onto the sequencer ASAP,” he wrote back, referring to the labor-intensive, round-the-clock effort required to read the entire genetic code of the bacteria and determine how easily the gene might spread.
“We had to drop everything else to get this done,” he explained later. “When [the test] came back positive, all hell broke loose.”

U.S. health officials and experts had been bracing for this moment since the gene’s discovery late last year in China. They’d hunted for mcr-1 in tens of thousands of samples from meat sources, animals and people.

And now that it’s definitively here, officials expect to find more cases — provoking even greater alarm. Immediately, the discovery in Pennsylvania gave new urgency to measures throughout the military and the federal government to determine where else the gene might be lurking and how to control its spread.

For infectious-disease experts, the nightmare scenario is for the gene to spread to bacteria that are now susceptible only to colistin. That would make them invincible to any antibiotic, unstoppable by the most lifesaving drugs of modern medicine.

‘This one popped up’

The gene mcr-1 was found first in pigs and people in China and then spread across Asia and Europe. By March, there were even more reports from France, Switzerland, Malaysia, Brazil and Argentina.

Still, the gene remains relatively rare. After the initial report from China, McGann’s team tested more than 3,000 antibiotic-resistant bacteria that had been collected from military facilities around the world. None contained the mcr-1 gene.

The Centers for Disease Control and Prevention estimates that drug-resistant bacteria cause 2 million illnesses and 23,000 deaths each year in the United States. Many service members wounded during the Iraq War contracted a strain of bacteria that the media later dubbed “Iraqibacter.” The normally harmless bacteria, found in soil and on skin, got into wounds and caused stubborn bloodstream infections, many of them resistant to many types of antibiotics. After about 2007, colistin was often one of the most effective treatment options available, McGann said.

That’s one reason the Army created the Multidrug-resistant Organism Repository and Surveillance Network (MRSN) in 2009; McGann is its chief of molecular research and diagnostics. Researchers say the detection of colistin-resistant bacteria in the Pennsylvania woman was a result of this strong surveillance system — but also sheer luck.

McGann got the initial call about a resistant E. coli sample from Kurt Schaecher, chief of the infectious-diseases laboratory at Walter Reed National Military Medical Center in Bethesda, Md. The hospital has the reference lab for about 100 military facilities, which regularly send it drug-resistant organisms.

Schaecher, who had just started in the job, was troubled by the number of reports coming in from around the world about the mcr-1 gene. Testing for colistin resistance was not routinely done in the lab, but he thought it would be prudent to start.

On May 12, he pulled out six of the lab’s most recent samples to test for resistance to colistin. The next day, the results were back. “And lo and behold, this one popped up,” he recalled, referring to the Pennsylvania sample.

He immediately alerted McGann. Both men were very surprised, Schaecher said.
They didn’t know why the bacteria weren’t killed by colistin — it could have been a spontaneous mutation rather than the mcr-1 gene. McGann’s team went straight to Bethesda to collect the sample for more testing.
Once McGann’s lab detected the gene on May 18, he alerted Schaecher and began fully sequencing the bacterium’s genome.

‘A NEEDLE IN A STACK OF NEEDLES’‘

Sequencing would tell everyone where the gene was located. Was it on the bacterium’s single chromosome? Or in a much more troubling spot, on something called a plasmid, a mobile piece of DNA that exists outside the chromosome?

If the gene were on the chromosome, that wouldn’t be so bad. The bacterium could pass the resistance only to its progeny, limiting the spread. But finding the gene on the plasmid would be much, much worse. Plasmids can transfer their genes to other bacteria, McGann said, even strains that aren’t closely related. The technical term for this ability is “promiscuity.”

The sequencing process took several days. The researchers had to extract the DNA from the bacteria and set up the sequencing machines that would read the entire genome and determine not only what genes were in the organism, but also if there were plasmids and what kind.

By 9 p.m. on May 20, they were ready to proceed. They ran the same test on two machines. One sequencer is less accurate but takes about eight hours. The other, larger sequencer is more accurate but takes 72 hours.
By the following day, early results confirmed that the gene was fully present and was most likely on a plasmid. Barely 24 hours later, another researcher had confirmed that the mcr-1 gene was present “on a promiscuous plasmid,” McGann said. The final verification took until May 23.
“It was like finding a needle in a stack of needles in another stack of needles,” Schaecher recalled.

McGann likened plasmids to cars that can carry a gene and transport it to other bacteria. Some plasmids can transfer those genes more readily than others. “This one moved pretty well,” he said. “Not quite a Fiat, more like a BMW.”

Even as the patient was being treated — her bacteria, while resistant to colistin, were sensitive to other drugs — researchers began to notify colleagues in the Defense Department and other government agencies. They alerted the CDC as well as the Health and Human Services and Agriculture departments that a superbug capable of spreading colistin resistance far and wide had finally surfaced in a person in the United States.

Some officials have complained that they should have been informed sooner. McGann said it would have been imprudent to send an alert before results were completely confirmed. Around the same time, he, Schaecher and the research team submitted a paper about their findings to a medical journal. The editor, Yohei Doi, an infectious-disease doctor at the University of Pittsburgh, raced to get it reviewed.

The paper was published May 26, and the discovery made headlines around the world.

These are the top superbug threats in the U.S.

Molecular Basis of Spirituality Science. Human body defends itself from attacks by pathogens deploying unique Protein Molecules called Antibodies. Superbugs synthesize Protein Molecules that can overcome body’s immune response. Neisseria gonorrhoeae causes infection called Gonorrhoea.

THE WHITE HOUSE HAS MADE THE GERMS ARE SERIOUS PRIORITY

Urgent threat. According to the White House plan to combat antibiotic-resistant bacteria, carbapenem-resistant Enterobacteriacea, CRE, is one of the country’s most urgent threats. Forty-four states have had at least one type of confirmed CREcase, which are resistant to nearly all antibiotics including last-resort drugs. CDC

Meanwhile, another surveillance system that includes the CDC, the USDA and the Food and Drug Administration has also been searching for the gene in bacteria collected from food animals, meat sources and people. Scientists have scoured more than 44,000 samples of salmonella bacteria and 9,000 samples of E. coli and Shigella bacteria.

That search is how the USDA scientists recently found the gene in a sample from a pig intestine. It also was in a strain of E. coli, and also on a plasmid. The USDA is working to determine the sample’s origin.

The strains and plasmids appear to be different, McGann said. That suggests that the gene is circulating through at least two — and possibly more — routes within the United States.

McGann said he learned about the mcr-1 gene in the pig sample only when his team notified government officials about its own finding. U.S. officials haven’t provided details about when the animal sample was found or why information about it wasn’t disclosed earlier.

Public health officials are most worried about the colistin-resistant gene spreading to a family of superbugs known as CRE, for carbapenem-resistant enterobacteriaceae, which the CDC has called one of the country’s most urgent public health threats. In some instances, CRE kills up to 50 percent of patients who become infected. Colistin is increasingly the last-resort drug to treat patients with such infections.

Already, doctors have been forced to rely on colistin as a last-line defense for many drug-resistant infections. Colistin, more than half a century old, is otherwise rarely used in human medicine because it can cause severe kidney damage.

The drug is not used in animals in the United States, but in Europe it has been widely used in veterinary medicine for decades to treat and prevent infection. In May, the European Medicines Agency recommended limiting its use in animals to halt the spread of resistance. It’s also widely used in farm animals in China.

The Army’s MRSN system receives 400 to 500 samples of multidrug-resistant organisms each month, primarily from its facilities around the world. About half are MRSA, or methicillin-resistant Staphylococcus aureus, bacteria resistant to many antibiotics that can cause a variety of problems, including skin infections and bloodstream infections. Another third are E. coli, and less than 1 percent are CRE.

The new information about the Pennsylvania woman’s colistin-resistant bacteria means McGann and his team can do more targeted searching in the repository of organisms. They’ve already scoured an additional 6,000 samples without again finding the gene.

This summer, all military services will be expected to begin providing the repository system with multidrug-resistant organisms.
By contrast, the national antibiotic resistance surveillance system that the CDC, USDA and FDA operate collectively serves all civilian hospitals in the country. It covers a far larger patient population and collects thousands of pathogen samples for each of the 15 antibiotic-resistant bacteria that the CDC has deemed to be urgent or serious threats.

Until now, the resistance testing has taken place at the CDC. But late last year, Congress approved $160 million in additional funding to boost the Obama administration’s antibiotic-resistance detection efforts. As a result, the agency plans to start funding state health departments this fall to do improved testing for antimicrobial resistance. That will include colistin.
