Modified C. novyi-NT bacterium produces precisely targeted anti-tumor response

A modified version of the Clostridium novyi (C. novyi-NT) bacterium can produce a strong and precisely targeted anti-tumor response in rats, dogs and now humans, according to a new report from Johns Hopkins Kimmel Cancer Center researchers.

Rectal and groin areas are frequent sites of colonization of community-associated MRSA

Colonization of methicillin-resistant Staphylococcus aureus (MRSA) allows people in the community to unknowingly harbor and spread this life-threatening bacteria.

Injections of anaerobic bacteria can shrink tumors in rats, dogs and human

Deep within most tumors lie areas that remain untouched by chemotherapy and radiation. These troublesome spots lack the blood and oxygen needed for traditional therapies to work, but provide the perfect target for a new cancer treatment using bacteria that thrive in oxygen-poor conditions.

Bacteria in critically ill patients may be growing increasingly resistant to common antiseptic

Bacteria that cause life-threatening bloodstream infections in critically ill patients may be growing increasingly resistant to a common hospital antiseptic, according to a recent study led by investigators at Johns Hopkins.

Researchers discover new clue to understanding how TB medication attacks dormant TB bacteria

Researchers at the Johns Hopkins Bloomberg School of Public Health say they have discovered a new clue to understanding how the most important medication for tuberculosis (TB) works to attack dormant TB bacteria in order to shorten treatment.

Review of fracking fluids raises concerns about several ingredients

As the oil and gas drilling technique called hydraulic fracturing (or "fracking") proliferates, a new study on the contents of the fluids involved in the process raises concerns about several ingredients.

Prevalence of bacterial meningitis drops in the United States

Advances in the prevention and treatment of an often fatal condition called bacterial meningitis appear to be paying dividends in the United States, report infectious disease experts at The University of Texas Health Science Center at Houston (UTHealth) in the journal The Lancet Infectious Diseases.

Lung-damaging bacterium turns body's antibody response in its favor

A lung-damaging bacterium turns the body's antibody response in its favor, according to a study published in The Journal of Experimental Medicine.

Natural gut bacterial community may affect intestinal function

Bacteria in the gut help the body to digest food, and stimulate the immune system. A PhD project at the National Food Institute, Technical University of Denmark, examines whether modulations of the gut bacterial composition affect intestinal integrity, i.e. the ability of the body to maintain a well-regulated barrier function that hinders bacteria from entering the body unintentionally.

Bacteria may depend more on gastrointestinal age than on environmental factors in babies

Scientists believe babies are born with digestive systems containing few or no bacteria. Their guts then quickly become colonized by microbes — good and bad — as they nurse or take bottles, receive medication and even as they are passed from one adoring relative to another.

Studies detect integrons that cause resistance to various antibiotics

In Mexico the sale of antibiotics for human consumption is controlled to prevent misuse, although in the veterinary sector failure in the implementation of the Official Mexican Standard NOM-064-ZOO-2000, "Guidelines for veterinarian products prescription", has prompted common bacteria such as Escherichia coli and Salmonella spp to become resistant to regular drugs such as streptomycin, trimethoprim, ampicillin, gentamicin, and tetracycline as a result of excess drug use.

New approach to knocking out parasite's genes

Plasmodium falciparum, the parasite that causes malaria, has proven notoriously resistant to scientists' efforts to study its genetics.

Gut microbiome analysis has potential to be a new tool for noninvasive colorectal cancer screening

Analysis of the gut microbiome more successfully distinguished healthy individuals from those with precancerous adenomatous polyps and those with invasive colorectal cancer compared with assessment of clinical risk factors and fecal occult blood testing, according to data published in Cancer Prevention Research, a journal of the American Association for Cancer Research.

Discovery lays groundwork for new class of antibiotics for Staphylococcus aureus infections

St. Jude Children's Research Hospital scientists have discovered an enzyme that regulates production of the toxins that contribute to potentially life-threatening Staphylococcus aureus infections. The study recently appeared in the scientific journal the Proceedings of the National Academy of Sciences.

MIT researchers generate liver tumors in adult mice

Sequencing the genomes of tumor cells has revealed thousands of mutations associated with cancer. One way to discover the role of these mutations is to breed a strain of mice that carry the genetic flaw — but breeding such mice is an expensive, time-consuming process.
