WASHINGTON Alshon Jeffery Eagles Jersey , July 11 (Xinhua) -- Bacteria carrying the MCR-1 "superbug" gene, which makes the last-resort antibiotic colistin useless against them, have been found in a second U.S. patient, researchers said Monday.
The gene was detected in an isolate of Escherichia coli that was originally recovered in 2015 from a patient in New York, according to the research published in Antimicrobial Agents and Chemotherapy, a journal of the American Society for Microbiology.
Previously, Escherichia coli bacteria carrying the MCR-1 gene was identified in a urine sample from a Pennsylvania woman with no recent travel outside of the U.S. this May.
The mcr-1 gene makes bacteria resistant to the antibiotic colistin Nelson Agholor Eagles Jersey , which is used as a last-resort drug to treat patients with multi-drug-resistant infections, including carbapenem-resistant Enterobacteriaceae (CRE).
U.S. health experts said the discoveries would be concerning because the mcr-1 gene exists on a plasmid, a small piece of DNA that is capable of jumping between different bacterial species, spreading any resistance genes it carries.
In the current study, the researchers, who coordinated the worldwide SENTRY Antimicrobial Surveillance Program, first tested 13 Jay Ajayi Eagles Jersey ,526 Escherichia coli and 7,480 Klebsiella pneumoniae strains that had been collected from hospitals in the Asia-Pacific region, Latin America, Europe, and North America in 2015.
They found that 390, or 1.9 percent, were resistant to colistin Brian Dawkins Eagles Jersey , and that 19 of these isolates tested positive for mcr-1.
The 19 isolates originated in ten countries representing all of the above regions. It involved a New York patient infected with Escherichia coli whose name was not disclosed.
The isolates that tested positive for mcr-1 were susceptible to several commonly used antimicrobial agents, including carbapenems, and recently approved anti-microbial agents that can be used against gram negative bacteria, said corresponding author Mariana Castanheira, Director for Molecular and Microbiology at Iowa-based JMI Laboratories.
That means these and similar isolates are unlikely to cause hard to treat infections at this time, Castanheira noted.
The presence of the mcr-1 gene, however Carson Wentz Eagles Jersey , and its ability to share its colistin resistance with other bacteria such as CRE raised the risk that pan-resistant bacteria could develop, the U.S. Centers for Disease Control and Prevention said earlier.
The mcr-1 gene was first isolated from food animals and humans in China in late 2015. Following that, scientists across the globe began searching for other bacteria containing the mcr-1 gene, and the bacteria have since been discovered in Europe and Canada.
RIYADH, Sept. 26 (Xinhua) -- The death toll in Thursday's stampede in Mina, neighboring the holy city Mecca, has risen to 769 Zach Ertz Black Jersey , Saudi Health Minister Khalid al-Falih said on Saturday.
Until now, the deadly disaster has left 769 pilgrims dead and 934 wounded, the minister said at a news conference.
The accident took place amid a rush of the stoning as part of Hajj rituals. Muslim pilgrims throw stones on a wall representing devil.
The stampede has drawn fierce criticism of the Saudi authorities' handling of safety, particularly from regional rival Iran.
Earlier on Saturday, the Saudi official media reported that the kingdom's top religious leader said the stampede was beyond human control.
"You are not responsible for what happened. As for the things that humans cannot control, you are not blamed for them. Fate and destiny are inevitable," Sheikh Abdul Aziz al-Sheikh told Crown Prince Mohammed bin Nayef Jake Elliott Black Jersey , who is also the minister of interior, the report said.
It was the second major accident involving massive casualties this month in Saudi Arabia. Earlier in September, 111 pilgrims were killed and 331 others injured in a crane crash in the grand mosque of Mecca.

BEIJING Alshon Jeffery Black Jersey , Jan. 31 (Xinhua) -- A red moon will grace the sky in most parts of China for over an hour during a total lunar eclipse on Wednesday night, according to the Beijing Planetarium.
The lunar eclipse, which is expected to begin at 7:48 p.m., will last for about five hours. As the moon passes into Earth's shadow, it will exhibit a reddish tinge as the sunlight is refracted while shining through Earth's atmosphere.
The red moon is expected to be visible between 8:51 p.m. and 10:08 p.m., lasting about one hour and 17 minutes.
The moon will also appear bigger as its orbit is near its closest point to Earth.
The last time a complete lunar eclipse occurred was September 28, 2015. The next lunar eclipse will happen on July 28.
The U.S. "Science" magazine that published on December 21 said that there are six major scientific areas of concern in 2013: the single-cell sequencing Nelson Agholor Black Jersey , the Planck the probing microwave background radiation, human connection group plan, the exploration under the Antarctic ice, cancer immunotherapy therapy and basic plant research. There are the three of them below.
Single cell sequencing: the cell is the basic unit of biology, and the researchers are working to try to make a separation, do some researches and make a comparison. The present biological research of genome sequencing mostly goes on after the extraction of the genetic material of a large number of cells, ignoring the differences between cells. Thus the single-cell sequencing can avoid this situation. Some scientists believe that by studying a single Jay Ajayi Black Jersey , intact cell’s genetic material can understand the working mechani.
