Clues to tuberculosis progression found in gene expression

Researchers at the Francis Crick Institute working with collaborators at the University of Leicester have identified how gene expression changes during different stages of tuberculosis (TB), including early after infection before any symptoms are clinically detectable. These changes provided information about the host immune response which could help the development of therapies against TB. The

Untangling COVID-19 and tuberculosis

As the UK marks one year since the country went into lockdown, we’ve also been looking further afield to countries disproportionately burdened by infectious diseases, including COVID-19. To mark this year’s World TB Day, we spoke to Robert Wilkinson, head of the Crick’s Tuberculosis Laboratory, about his team’s work in Africa, understanding the links between

Coronavirus: Tuberculosis vaccine may help in reducing Covid-19 deaths

A century-old tuberculosis vaccine may play a role in reducing death due to Covid-19 infection, a preliminary study has suggested. Researchers from the US-based the National Institute of Allergy and Infectious Diseases of the National Institutes of Health made the link to Bacille Calmette-Guerin, or BCG, after comparing data on Covid-19 mortality rates across the

New strain of strep a is causing scarlet fever and invasive infections in England and Wales: Scientists warn vigilance is needed to monitor impact of new bacterial strain on public health

Scientists studying scarlet fever have identified a new strain of disease-causing bacteria, which may explain a rise in more serious Strep A infections in England and Wales, according to results from cases in London and across England and Wales from 2014-16 published in The Lancet Infectious Diseases journal. In 2014, England experienced the biggest surge

New vaccine targets killer disease tuberculosis

There is only one existing vaccine for TB and it is not effective in adults. Researchers at the Centenary Institute and University of Sydney will next test their new vaccine in clinical trials with humans. Australian medical researchers from the Centenary Institute and the University of Sydney have successfully developed and tested on mice a

Earlier diagnosis and treatment assessment of tuberculosis achieved with pet/ct

Research presented at the Society of Nuclear Medicine and Molecular Imaging’s 2019 Annual Meeting shows that molecular imaging with 18F-FDG positron emission tomography/computed tomography (PET/CT) can evaluate tuberculosis at the molecular level, effectively identifying diseased areas and guiding treatment for patients. According to the World Health Association, tuberculosis is one of the top 10 causes

How ‘superbug’ E. coli clones take over human gut

A ‘superbug’ clone of E. coli has evolved to prevent itself from becoming so dominant that it could potentially wipe out the bacteria from existence, scientists led by the University of Birmingham have discovered. The researchers investigated how and why a clone of E. coli called ST131 — dubbed a ‘superbug’ because it is resistant

New tools and strategies for tuberculosis diagnosis, care, and elimination: A PLOS Medicine special

This week, publication of a special issue on tuberculosis (TB) begins in PLOS Medicine, advised by guest editors Richard Chaisson of Johns Hopkins University, Claudia Denkinger of the University of Heidelberg, and Mark Hatherill of the South African Tuberculosis Vaccine Institute. An estimated 10 million people developed tuberculosis (TB) and 1.6 million died of TB

Drug-resistant tuberculosis: A new study offers new hope

Tuberculosis (TB) is the leading cause of death in the world from a single infectious disease, causing more deaths than HIV/AIDS. In 2017, 10 million people developed TB disease globally and an estimated 1.6 million died. One of the biggest blocks to beating the epidemic is the growing resistance to drugs that have previously cured

New tuberculosis drug may shorten treatment time for patients

A new experimental antibiotic for tuberculosis has been shown to be more effective against TB than isoniazid, a decades-old drug which is currently one of the standard treatments. In mouse studies, the new drug showed a much lower tendency to develop resistance, and it remains in the tissues where the Mycobacterium tuberculosis bacteria reside for

South Asians at risk for tuberculosis often are not tested

Many South Asian immigrants from countries where tuberculosis (TB) is common do not get tested even though they are at high risk for developing the disease, according to a recent study by Rutgers University and St. Peter’s University Hospital. Tuberculosis, which mainly affects the lungs, kills more people worldwide—about 1.6 million—than any other single infectious

Managing the complexities and risks of HIV and tuberculosis coinfection

A new study identified a significant association between HIV infection and complexities of treating patients with tuberculosis coinfection. Patients with HIV were more likely to have more tuberculosis drug-related adverse events, more hospital readmissions, and longer tuberculosis treatment duration, as reported in AIDS Research and Human Retroviruses, a peer-reviewed journal from Mary Ann Liebert, Inc.,

Governments to discuss tackling tuberculosis at UN summit

Governments from around the world will gather Wednesday to discuss the persistent scourge of tuberculosis, which last year claimed more lives than any other communicable disease. About 1.3 million people worldwide died of TB in 2017. A further 300,000 people with both HIV and TB died in last year, according to World Health Organization figures

How damaging immune cells develop during tuberculosis

Insights into how harmful white blood cells form during tuberculosis infection point to novel targets for pharmacological interventions, according to a study published in the open-access journal PLOS Pathogens by Valentina Guerrini and Maria Laura Gennaro of Rutgers New Jersey Medical School, and colleagues. Foam cells are a type of white blood cell, known as
