CDC Study: Antibiotics Used as Pesticides Facilitate Antibiotic Resistance

The Centers for Disease Control and Prevention have conducted a study that finds that medically important antibiotics that the EPA wants to re-approve for expanded pesticide use on crops can facilitate antibiotic resistance in bacteria. Those pathogens pose "urgent" and "serious" threats to human health. The results of this study were obtained by the Center for Biological Diversity under the Freedom of Information Act. Those dangerous antibiotic resistant-bacteria include MSA, nightmare bacteria (Cabapenem-resistant Enterobacteriaceae (CRE), and Vancomycin-resistant Enterococcus. Those pathogens cause more than 100,000 infections and 13,000 deaths every year in the United States. Nathan Donley, a senior scientist with the Center for Biological Diversity said in a statement, "It’s … [Read more...]

CDC Investing Millions in Enhanced Antibiotic Resistance Testing

The Centers for Disease Control and Prevention (CDC) is investing $77 million in efforts to track and fight antibiotic resistance. The money is going to public health departments in all 50 states and Puerto Rico. The hope is that officials will develop new ways to combat antibiotic resistant bacteria in food, healthcare facilities, and communities. The funding will open a new surveillance center for TB. And the overall focus is on enhancing testing capabilities in the agency's regional antibiotic resistance labs. Seven regional labs that are part of the CDC's Antibiotic Resistance Lab Network will be able to expand antibiotic susceptibility testing for Candida auras. This bacteria has shown resistance to all three classes of drugs that are usually used to fight these infections. … [Read more...]

Researchers Find One Mechanism for Antibiotic Resistance

A study conducted at Harvard and MIT and published in the journal eLife has discovered one way that bacteria become resistant to drugs. Individual mutations that increase pathogenic bacteria's resistance to multiple antibiotics has not been fully explored. About 23,000 Americans die every year from bacterial and fungal infections that are resistant to antibiotics. That number is expected to increase to 10,000,000 by the year 2050 if new, effective antibiotics are not developed. Scientist cultured the bacteria Mycobacterium smegmatis, a cousin of the bacteria that causes tuberculosis. The scientists grew the bacteria until they formed colonies, and then exposed the colonies to low doses of antibiotics that killed the bacteria slowly. Mutant colonies arose after that … [Read more...]

CDC Tracks Antibiotic Resistance Gene in Bacteria

The Centers for Disease Control and Prevention (CDC) is tracking the mcr-1 gene in bacteria. This gene can make bacteria resistant to colistin, an antibiotic that is the "last resort" drug for some multidrug-resistant pathogens. Colistin is considered an old drug and is rarely used because it can damage the kidneys. The gene was found in China for the first time in November 2015. The map shows where the mcr-1 gene has been reported in the United States as of January 1, 2017. In the states highlighted in yellow, human infections have been reported. The states highlighted in orange have animal infections. The mcr-1 gene is on a plasmid, which is a piece of DNA that can move from one pathogen to another. Because of the ease of this transfer, bacteria that area already resistant to … [Read more...]

CDC Spending $67 Million to Fight Antibiotic Resistance

The Centers for Disease Control and Prevention is going to spend $67,000,000 to help fight the development of antibiotic-resistant bacteria. That money will go to health departments across the country in all 50 states and Puerto Rico, and to local health departments in six major cities. Those six cities include New York City, Houston, Chicago, D.C., Los Angeles, and Philadelphia. The money will be available to jurisdictions starting today, August 1, 2016. That money will help labs test for multidrug-resistant bacteria and will aid in whole genome sequencing (WGS) of Salmonella, Shigella, and other intestinal bacteria. Officials hope that this funding and new testing will help the government respond more quickly to food poisoning outbreaks. That funding will also help support seven … [Read more...]

Minnesota Agencies Reveal Plan to Fight Antibiotic Resistance

Four agencies in Minnesota have launched a five year plan to fight antibiotic resistance. The partners are in public health, health care, agribusiness, and environmental protection. They are the Minnesota Department of Health, Minnesota Department of Agriculture, Board of Animal Health, and Minnesota Pollution Control Agency. They will work together to "promote judicious antibiotic use and stewardship in order to reduce the impact of resistant bacteria." The widespread use of antibiotics over the past few decades has caused an alarming increase in antibiotic-resistant infections. Bacteria are able to develop resistance to antibiotics through natural selection. While the effectiveness of medically important antibiotics has been decreasing, the rate of antibiotic resistant bacteria … [Read more...]

Senators Follow up on Unanswered Antibiotic Resistance Questions

United States Senators Elizabeth Warren (D-MA), Dianne Feinstein (D-CA), and Kirsten Gillibrand (D-NY) sent a letter to the Interagency Task Force for Combating Antibiotic-Resistant Bacteria, asking again for information on how that body plans to address critical gaps in the FDA policies on overuse of antibiotics in food animals. A letter was sent in December 2014, but they have not received a formal response. The letter states, "we are extremely disappointed that we have not received a formal response form your office. Antibiotic-resistant bacteria present a major public health threat and public health experts agree that antibiotic resistance stems not only from antibiotic use in human medicine, but also from use in animals." The senators asked for a response within 30 days. They … [Read more...]

FDA Releases NARMS Report on Antibiotic Resistance

The Food and Drug Administration (FDA) has released its 2012-2013 National Antimicrobial Resistance Monitoring System (NARMS) Integrated Report. The report focuses on major food born pathogens that are resistant to antibiotics important in human medicine, and on multidrug resistant pathogens. NARMS screens for non-typhoidal Salmonella, Campylobacter, E. coli, and Enterococcus. Salmonella and Campylobacter are the leading causes of bacterial food poisoning. The report reveals "mostly encouraging findings, with some areas of concern." About 80% of human Salmonella isolates are not resistant to any of the tested antibiotics. This number has not changed in the past 10 years. In addition, Salmonella multi-drug resistance has not changed, and the number of multi-drug resistant Salmonella … [Read more...]

Antibiotic Resistance Increasing for Some Pathogens, CDC Reports

Some types of Salmonella and other bacteria are increasing their resistance to antibiotics, according to a new report from the National Antimicrobial Resistance Monitoring System (NARMS) which tracks antibiotic resistance in humans, farm animals and deli meat. Each year, about 440,000 Americans develop antibiotic-resistant infections from foodborne germs. Created in 1996, NARMS is an interagency collaboration of the Centers for Disease Control and Prevention (CDC), the U.S. Food and Drug Administration (FDA) and the U.S. Department of Agriculture (USDA). It tracks antibiotic resistance in six pathogens: non-typhoidal Salmonella, typhoidal Salmonella, Shigella, Campylobacter, E. coli O157, and Vibrio. The new report, based on information from 5,000 isolates gathered in 2013, … [Read more...]

White House Releases Report on Combating Antibiotic Resistance

The President's Council of Advisors on Science and Technology (PCAST) has released a report today about combating antibiotic resistance. The White House also released a National Strategy on Combating Antibiotic Resistant Bacteria and a Presidential Executive Order which emphasizes the importance of tackling this challenge. Antibiotic resistant bacteria are evolving at an alarming rate and are growing faster than the development of new antibiotics. The cost of antibiotic infections in the United States every year is more than $20 billion. The cost of lost productivity due to antibiotic-resistant infections is $35 billion every year. The World Health Organization has issued a warning too, about the dangers of not being able to treat resistant infections. PCAST recommends that there be … [Read more...]
