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.

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.

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.

Current hospital cleaning protocol may be inadequate to rid MDR A. baumannii

Current hospital cleaning protocol may be inadequate to rid patient rooms of multidrug-resistant (MDR) Acinetobacter baumannii, according to a study in the December issue of the American Journal of Infection Control, the official publication of the Association for Professionals in Infection Control and Epidemiology (APIC).

Researchers study antimicrobial peptides in fish gills to find solution for blocking human infections

Living in an environment teaming with bacteria and fungi, fish have evolved powerful defenses against waterborne pathogens, including antimicrobial peptides located in their gills. Undergraduate researchers at Worcester Polytechnic Institute are studying the biology and the mechanics of one of those peptides with the hope they can use that knowledge to create engineered surfaces that kill bacteria responsible for foodborne illnesses and hospital-acquired infections.

Broad range of human activities affects spread of vector-borne zoonotic diseases, experts say

West Nile virus, Lyme disease, dengue fever, and plague are examples of "vector-borne zoonotic diseases," caused by pathogens that naturally infect wildlife and are transmitted to humans by vectors such as mosquitoes or ticks.

SLU study to use various assays for new TB vaccine development

A pilot study at Saint Louis University Center for Vaccine Development could shape the future of tuberculosis vaccine research by developing tests to identify the most promising vaccine candidates to address this global health crisis.

New antifungal drugs could be developed based on substance bacteria use to decompose mushrooms

Soft rot diseases cause a great deal of damage in agriculture, and turn fruits, vegetables, and mushrooms to mush. By using imaging mass spectrometry together with genetic and bioinformatic techniques (genome mining), German researchers have now discovered the substance the bacteria use to decompose mushrooms.

Parainfluenza virus 5 may serve as foundation for next breakthrough in human vaccine development

Researchers at the University of Georgia have discovered that a virus commonly found in dogs may serve as the foundation for the next great breakthrough in human vaccine development.

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.

Research reveals surprisingly complex protein-coding capacity of human cytomegalovirus

New findings reveal the surprisingly complex protein-coding capacity of the human cytomegalovirus, or HCMV, and provide the first steps toward understanding how the virus manipulates human cells during infection. The genome of the HCMV was first sequenced over 20 years ago, but researchers have now investigated the proteome-the complete set of expressed proteins-of this common pathogen as well.

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.

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.

Emory University, Georgia Tech to establish Malaria Host-Pathogen Interaction Center

The National Institute of Allergy and Infectious Diseases, part of the National Institutes of Health, has awarded a five-year contract of up to $19.4 million, depending on contract options exercised, to establish the Malaria Host-Pathogen Interaction Center (MaHPIC).

Flu virus suppresses body's ability to defend against bacteria

When infected with influenza, the body becomes an easy target for bacteria. The flu virus alters the host's immune system and compromises its capacity to effectively fight off bacterial infections. Now, a team of immunologists at the Helmholtz Centre for Infection Research (HZI) and cooperation partners has discovered that an immune system molecule called TLR7 is partly to blame. The molecule recognizes the viral genome - and then signals scavenger cells of the immune system to ingest fewer bacteria.

Tuberculosis pathogen has an ingenious defence mechanism against oxygen

Flemish biologists lead by Joris Messens (VIB / Vrije Universiteit Brussel) have discovered that Mycobacterium tuberculosis - the bacterium that causes tuberculosis - has an ingenious defence mechanism against oxygen. This knowledge is important in the search for a treatment for tuberculosis. 9.4 million people are infected with tuberculosis annually and 1.7 million people die as a result.
