A total of 80 surgical scrub garments, tops and bottoms were collected from multiple healthcare facilities across the US. There were 10 sets of scrubs in each category: single-use; home-laundered; facility-laundered and third-party laundered.

"According to these results, a healthcare professional beginning his or her shift in home-laundered scrubs would essentially be wearing scrubs with the same quantity of bacteria as the scrubs of a healthcare professional finishing a shift in worn scrubs," said Heather Beitz, director of clinical research for Molnlycke Health Care.

Triclosan Exposure Levels Increasing in Humans http://bio-protect.net/triclosan-exposure-levels-increasing-in-humans/?utm_source=rss&utm_medium=rss&utm_campaign=triclosan-exposure-levels-increasing-in-humans http://bio-protect.net/triclosan-exposure-levels-increasing-in-humans/#comments Sat, 18 Jun 2011 22:49:07 +0000 admin http://bio-protect.net/?p=112 Levels of the chemical triclosan have increased in humans by an average of 50 percent since 2004, according to newly updated data from the Centers for Disease Control and Prevention (CDC). Meanwhile, a new study out of the University of Toledo has found that both triclosan and triclocarban can enter the food chain through of the use of contaminated wastewater or fertilizer in agricultural fields. Each of these findings on its own is troubling, but together they make the case for banning the two chemicals even stronger, according to health experts at the Natural Resources Defense Council (NRDC), a national, nonprofit organization of scientists, lawyers and environmental specialists dedicated to protecting public health and the environment.

Triclosan and triclocarban are found in consumer and personal care products, such as hand soap, labeled antibacterial or antimicrobial. But the two chemicals are suspected endocrine disruptors that can interfere with hormones needed for the brain and reproductive system to develop properly. The NRDC says that the Food and Drug Administration (FDA) has admitted that using hand soap containing these chemicals actually does not work any better than regular soap. Last week, the NRDC sued the FDA to force the agency to issue a final rule on the safety and effectiveness of the two chemicals that has been three decades in the making.

Silver Nanoparticles Stop Sperm Stem Cell Growth http://bio-protect.net/silver-nanoparticles-stop-sperm-stem-cell-growth/?utm_source=rss&utm_medium=rss&utm_campaign=silver-nanoparticles-stop-sperm-stem-cell-growth http://bio-protect.net/silver-nanoparticles-stop-sperm-stem-cell-growth/#comments Sun, 10 Apr 2011 22:55:43 +0000 admin http://bio-protect.net/?p=121 A new study has identified exactly how silver nanoparticles cause male reproductive cells to stop growing.

Minute materials used in a number of consumer products such as antimicrobial agents can interrupt important cell signaling within male reproductive sperm cells, causing them to stop growing, according to a new study that builds on previous work by the same research group.

In prior studies, the scientists reported how smaller-sized silver nanoparticles – in the 10 – 25 nanometer range – decreased the growth of male stem cells when they were exposed at concentrations greater than 10 micrograms per milliliter (ug/ml).

The new study is the first to identify how the silver nanoparticles stop the sperm stem cells from growing. The biggest effects were caused by the smallest-sized nanoparticles tested.

EPA Acts on Petition to Regulate Nano-Silver Products http://bio-protect.net/epa-acts-on-petition-to-regulate-nano-silver-products/?utm_source=rss&utm_medium=rss&utm_campaign=epa-acts-on-petition-to-regulate-nano-silver-products http://bio-protect.net/epa-acts-on-petition-to-regulate-nano-silver-products/#comments Sun, 10 Apr 2011 22:54:57 +0000 admin http://bio-protect.net/?p=119 Acknowledging the critical need for in-depth review of products utilizing nanotechnology pesticides, the Environmental Protection Agency (EPA) opened a 60-day public comment period in response to a petition filed by the International Center for Technology Assessment (ICTA), which demands the agency stop the sale of numerous consumer products with nano-silver.

In the Federal Registry notice released yesterday, EPA determined that ICTA's petition "raises serious issues that potentially affect private and public sector stakeholders" and is instituting a 60-day period for public comment. EPA will review the petition and any comments received "before deciding how best to respond to the petition."

Antibacterial Household Products: Cause for Concern http://bio-protect.net/antibacterial-household-products-cause-for-concern/?utm_source=rss&utm_medium=rss&utm_campaign=antibacterial-household-products-cause-for-concern http://bio-protect.net/antibacterial-household-products-cause-for-concern/#comments Thu, 30 Sep 2010 22:57:48 +0000 admin http://bio-protect.net/?p=130 Presentation from the 2000 Emerging Infectious Diseases Conference in Atlanta, Georgia

Stuart B. Levy

Tufts University School of Medicine, Boston, Massachusetts, USA

The recent entry of products containing antibacterial agents into healthy households has escalated from a few dozen products in the mid-1990s to more than 700 today. Antibacterial products were developed and have been successfully used to prevent transmission of disease-causing microorganisms among patients, particularly in hospitals. They are now being added to products used in healthy households, even though an added health benefit has not been demonstrated. Scientists are concerned that the antibacterial agents will select bacteria resistant to them and cross-resistant to antibiotics. Moreover, if they alter a person's microflora, they may negatively affect the normal maturation of the T helper cell response of the immune system to commensal flora antigens; this change could lead to a greater chance of allergies in children. As with antibiotics, prudent use of these products is urged. Their designated purpose is to protect vulnerable patients.

Antibiotics are critical to the treatment of bacterial infections. However, after years of overuse and misuse of these drugs, bacteria have developed antibiotic resistance, which has become a global health crisis (1, 2). The relatively recent increase of surface antibacterial agents or biocides into healthy households may contribute to the resistance problem

South Dakota Scientists Invent Germ-Killing Wall Paint http://bio-protect.net/south-dakota-scientists-invent-germ-killing-wall-paint/?utm_source=rss&utm_medium=rss&utm_campaign=south-dakota-scientists-invent-germ-killing-wall-paint http://bio-protect.net/south-dakota-scientists-invent-germ-killing-wall-paint/#comments Mon, 30 Aug 2010 23:06:50 +0000 admin http://bio-protect.net/?p=149 Someday soon, the paint on your wall may be able to kill disease-causing bacteria, as well as mold, fungi, viruses, and other harmful organisms.

Scientists at the University of South Dakota have invented a new germ-killing molecule that can be added to commercial brands of paint to give the paint long-lasting antimicrobial properties.

The molecule includes a bleach-like substance called an N-halamine. N-halamines are already used widely, but the South Dakota researchers were able to develop a new type known as Cl-TMPM.

Some bacteria have developed mechanisms which render them resistant to many of the antibiotics normally used for their treatment (multi-drug resistant bacteria), so pose particular difficulties, as there may be few or no alternative options for therapy. They constitute a growing and global public health problem. WHO suggests that countries should be prepared to implement hospital infection control measures to limit the spread of multi-drug resistant strains and to reinforce national policy on prudent use of antibiotics, reducing the generation of antibiotic resistant bacteria.

Sir Alexander Fleming discovered penicillin 75 years ago. Antibiotics first became widely used in the World War II era. 50 years+ later, antibiotics are no longer as effective as they were perceived to be. Sir Alexander Fleming predicated this would happen 75 years ago.

Drug resistance happens when germs develop ways to survive the use of medicines meant to kill or weaken them. Yes, bacteria has found ways to outwit…
