Bacteriophages may play an important role in competition among bacterial strains

Unique viruses called bacteriophages may play an important role in competition among bacterial strains, influencing the overall ecosystem of the human intestine, scientists at The University of Texas at Arlington and UT Southwestern Medical Center say.

New coronavirus can infect cells from humans and bats alike

The SARS epidemic of 2002-2003 was short-lived, but a novel type of human coronavirus that is alarming public health authorities can infect cells from humans and bats alike, a fact that could make the animals a continuing source of infection, according to a study to be published in in mBio-, the online open-access journal of the American Society for Microbiology, on December 11.

Researchers track emergence and global spread of healthcare-associated C. difficile

Researchers show that the global epidemic of Clostridium difficile 027/NAP1/BI in the early to mid-2000s was caused by the spread of two different but highly related strains of the bacterium rather than one as was previously thought. The spread and persistence of both epidemics were driven by the acquisition of resistance to a frontline antibiotic.

Targeting RAD52 protein can block the process by which leukemia stem cells repair themselves

Despite treatment with imatinib, a successful drug that targets chronic myeloid leukemia (CML), a deadly type of cancer, some patients may continue to be at risk for relapse because a tiny pool of stem cells is resistant to treatment and may even accumulate additional genetic aberrations, eventually leading to disease progression and relapse. These leukemia stem cells are full of genetic errors, loaded with potentially lethal breaks in DNA, and are in a state of constant self-repair.

C5aRA treatment could be effective against periodontitis

Periodontitis, a form of chronic gum disease that affects nearly half of the U.S. adult population, results when the bacterial community in the mouth becomes unbalanced, leading to inflammation and eventually bone loss. In its most severe form, which affects 8.5 percent of U.S. adults, periodontitis can impact systemic health.

Breast milk banks: an interview with Dr. Pieter Koorts

The available literature clearly demonstrates that in almost all circumstances a mother’s own breast milk is the ideal food for her infant. This is particularly important for preterm infants. Preterm infants are babies born before 37 completed weeks of pregnancy.

New method can generate stable human mesenchymal stem cells for bone engineering

Human mesenchymal stem cells (hMSCs) can develop into bone cells and are useful for tissue engineering and regeneration. However, when grown in the laboratory they quickly lose their ability to continue dividing and they die.

New clues about B. burgdorferi could lead to novel strategy to reduce Lyme disease

New clues about the bacteria that cause Lyme disease could lead to a novel strategy to reduce infections, according to a study to be published in mBio-, the online open-access journal of the American Society for Microbiology, on December 4.

Hebrew University researchers pave way for development of new approaches to cure malaria

More than a million people die each year of malaria caused by different strains of the Plasmodium parasite transmitted by the Anopheles mosquito. The medical world has yet to find an effective vaccine against the deadly parasite, which mainly affects pregnant women and children under the age of five. By figuring out how the most dangerous strain evades the watchful eye of the immune system, researchers from the Hebrew University of Jerusalem have now paved the way for the development of new approaches to cure this acute infection.

Specific transporters could be exploited to deliver toxic substances into cancer cells

Whitehead Institute scientists report that certain molecules present in high concentrations on the surfaces of many cancer cells could be exploited to funnel lethal toxic molecules into the malignant cells. In such an approach, the overexpression of specific transporters could be exploited to deliver toxic substances into cancer cells.

Loss of either T-bet or Eomes protein reduces immune system's ability to fight viral infection

When you get an acute infection, such as influenza, the body generally responds with a coordinated response of immune-cell proliferation and attack that rapidly clears the pathogen. Then, their mission done, the immune system stands down, leaving a population of sentinel memory cells to rapidly redeploy the immune system in the event of reinfection.

Study: Tdap vaccination safe for seniors

A new study of the safety of the tetanus-diphtheria-acellular pertussis (Tdap) vaccine supports the recommendation that those 65 and older get the vaccine to protect themselves and others, particularly young babies, from pertussis.

GW professor receives federal grant to study effects of microsporidia in HIV patients

Imtiaz A. Khan, M.D., professor of microbiology, immunology, and tropical medicine at the George Washington University School of Medicine and Health Sciences, received a $1.6 million federal grant from the National Institute of Allergy and Infectious Diseases to study the effects of microsporidia-opportunistic inter-cellular pathogens-that cause morbidity and mortality in HIV patients.

Chronic suppurative lung disease: an interview with Dr Robyn Marsh

Chronic suppurative lung disease, or CSLD, is used to describe a range of lung diseases characterised by a chronic wet cough and progressive lung damage. We are interested in the non-cystic fibrosis forms of the disease with a focus on bronchiectasis – the severe form of CSLD.

Avermectin family of drugs shows promise against TB

A well-established family of drugs used to treat parasitic diseases is showing surprising potential as a therapy for tuberculosis (TB), according to new research from University of British Columbia microbiologists.

Many microorganisms have ability to combat nitrous oxide

The environment has a more formidable opponent than carbon dioxide. Another greenhouse gas, nitrous oxide, is 300 times more potent and also destroys the ozone layer each time it is released into the atmosphere through agricultural practices, sewage treatment and fossil fuel combustion.

Microbiologists discover how the spread of antibiotic resistance works in pneumococcus

Antibiotic resistance results from bacteria's uncanny ability to morph and adapt, outwitting pharmaceuticals that are supposed to kill them. But exactly how the bacteria acquire and spread that resistance inside individuals carrying them is not well-established for most bacterial organisms.

Human Food Project, University of Colorado Boulder launch American Gut

Ever wondered who is living in your gut, and what they're doing? The trillions of microbial partners in and on our bodies outnumber our own cells by as many as 10 to 1 and do all sorts of important jobs, from helping digest the food we eat this Thanksgiving to building up our immune systems.

Genetic study: Novel coronavirus most closely related to viruses in bats

The virus that is causing alarm among global public health authorities after it killed a man in Jeddah, Saudi Arabia earlier this year and is now linked to two other cases of disease is a novel type of coronavirus most closely related to viruses found in bats, according to a genetic analysis to be published in mBio-, the online open-access journal of the American Society for Microbiology, on November 20.
