Pneumonia is a leading cause of death and hospitalization, costing health care systems billions of dollars and an estimated 600,000 adult deaths worldwide each year. Pneumococcal disease is caused by the bacterium Streptococcus pneumoniae and the term describes a group of illnesses, including invasive infections, such as bacteremia/sepsis and meningitis, as well as pneumonia and upper respiratory tract infections. Although all age groups may be affected, the highest rate of pneumococcal disease occurs in young children and older adults. In addition, persons suffering from a wide range of chronic conditions (eg, diabetes, cardiovascular disease) and immune deficiencies are at increased risk.
In nature, the majority of bacteria adhere to a minimalistic lifestyle. When faced with nutrient scarcity or stress, they initiate a controlled shutdown of their metabolism, entering a resting state.
Researchers at the University of São Paulo (USP) in Brazil, partnering with colleagues in Australia, have identified a novel bacterial protein that can keep human cells healthy even when the cells have a heavy bacterial burden.
Some strains of heavily antibiotic-resistant bacteria in Ghana are not successful at spreading outside of the hospital, suggesting that control measures can be focused on clinical settings to help curb treatment-resistant infections.
Scientists at the University of Sheffield have uncovered an evolutionary gateway that enables pneumonia cells to develop resistance to antibiotics.
The first Americans over age 60 just started rolling up their sleeves to get vaccinated against respiratory syncytial virus, or RSV, now that brand-new vaccines have started to arrive at pharmacies and clinics.
According to a recent JAMA study by scientists at the University of Pittsburgh and UPMC, a nasal swab to screen for three types of bacteria can reveal whether or not antibiotics are likely to be beneficial in children with suspected sinusitis.
Two anti-inflammatory drugs, abatacept and infliximab, reduced deaths among patients hospitalized with severe COVID-19, according to a national study led by Washington University School of Medicine in St. Louis.
A population of unconventional white blood cells has recently captured the attention of immunologists and clinicians alike.
A researcher at the University of Central Florida College of Medicine has created a novel, more effective therapy for acute respiratory viral infections, a significant global cause of illness each year.
Alfalfa, also known in Latin as Medicago sativa, is an agricultural crop that is part of the legume family. It is known as a protein-rich food source for dairy cattle that is easily digested and can lead to increased milk production.
Developing and testing new treatments or vaccines for humans almost always requires animal trials, but these experiments can sometimes take years to complete and can raise ethical concerns about the animals' treatment.
Increases in multidrug-resistance in the bacteria Streptococcus pneumoniae have made it the fourth-leading cause of death associated with antibiotic resistance.
Pneumococcal disease leads to over three million hospitalizations and hundreds of thousands of deaths annually.
Experts from the University of Barcelona, the Institute for Advanced Chemistry of Catalonia (IQAC-CSIC), the Institute of Microelectronics of Barcelona (IMB-CNM-CSIC) and the Aragon Nanoscience and Materials Institute of Aragon (INMA) -;a joint institute of the CSIC and the University of Zaragoza-; have developed a new method to detect RNA viruses based on the triplex-forming probe technology.
An international consortium co-led by Vanderbilt University Medical Center immunogeneticist Rubén Martínez-Barricarte, PhD, has discovered a new genetic disorder that causes immunodeficiency and profound susceptibility to opportunistic infections including life-threatening fungal pneumonia.
A new study by the University of Surrey suggests that Parkinson’s disease may begin in the gut and pass on to the brain.
For the first time, researchers demonstrate that monkeys with a more social nature—those that groom or are groomed more frequently and with more grooming partners—have a better gut microbiome.
The overuse of antibiotics has forced microorganisms to evolve defenses against this kind of treatment. Antibiotic resistance is a problem that the WHO now views as one of the major hazards to human health.
Researchers investigating the effects of an organic compound on drug-resistant bacteria found how it can impede and destroy a germ that causes significant illness or even death in some situations.
A naturally occurring substance known as hydroquinine has been discovered by researchers to have bacterial killing ability against a variety of pathogens.
