WASHINGTON Robert Huth 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, 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 13,526 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, 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, 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.

HOUSTON, Jan. 13 (Xinhua) -- U.S. oil and gas services company Halliburton on Tuesday announced job cuts in Houston, Taxas as part of its bid to confront the weakening market conditions.

The multinational company's move came after it announced last month that it would cut 1,000 jobs across the company. But the company did not say exactly how many employees it had laid off this time.

In a statement to local media, Halliburton spokeswoman Emily Mir said that the company had made some workforce reductions in Houston. While these reductions were difficult, the company believed they were necessary to work through this challenging market.

"We will continue to monitor closely the business environment and will make adjustments to the cost structure of their business as needed," she said.

In November last year, the Houston-based company announced that it would buy its rival Baker Hughes for 34.6 billion U.S. dollars in a cash and stock transaction, marking one of the biggest mergers in the oilfield services ever.

Halliburton and Baker Hughes, the second and third biggest oilfield service companies in the world behind Slumberger, have 136,000 employees around the world. They said the combination would result in 2 billion dollars in cost savings and revenue increases.

In addition, OFS Energy Fund, a Houston-based investment firm,also announced on Monday layoffs of 150 employees from the oilfield companies it owned in the states of Texas, Louisiana, Oklahoma and elsewhere.

World oil prices have fallen nearly 50 percent from last year, hovering at 45 U.S. dollars a barrel, and that is nearly a six-year low. As a result, some energy giants like ConocoPhillips and Continental Resources Inc. have sharply reduced their annual spending budgets.

PARIS, Aug. 26 (Xinhua) -- For the first time, Video refereeing will be trialled in a friendly match between Italy and France in Bari on Sept. 1, FIFA announced on Friday.

IFAB, the body who govern the rules of the game, support the tests. And an extra assistant referee will communicate with the on-pitch referee during the game.

Video tests have been used in the third tier of the United States since July.

BEIJING, Oct. 18 (Xinhua) -- Xi Jinping said Wednesday that "achieving national rejuvenation will be no walk in the park, and it will take more than drum beating and gong clanging to get there."

Xi made the remarks in a report to the 19th National Congress of the Communist Party of China (CPC) at the Great Hall of the People in central Beijing.

Citing a Chinese saying that "the last leg of a journey just marks the halfway point," Xi demands every Party member "be prepared to work even harder toward this goal."

"Today, we are closer, more confident, and more capable than ever before of making the goal of national rejuvenation a reality," Xi said.

"Realizing our great dream demands a great struggle," Xi said.

"All thinking a.
