Meningitis is an infection of the fluid of a person's spinal cord and the fluid that surrounds the brain. People sometimes refer to it as spinal meningitis. Meningitis is usually caused by a viral or bacterial infection. Knowing whether meningitis is caused by a virus or bacterium is important because the severity of illness and the treatment differ. Viral meningitis is generally less severe and resolves without specific treatment, while bacterial meningitis can be quite severe and may result in brain damage, hearing loss, or learning disability. For bacterial meningitis, it is also important to know which type of bacteria is causing the meningitis because antibiotics can prevent some types from spreading and infecting other people. Before the 1990s, Haemophilus influenzae type b (Hib) was the leading cause of bacterial meningitis, but new vaccines being given to all children as part of their routine immunizations have reduced the occurrence of invasive disease due to H. influenzae. Today, Streptococcus pneumoniae and Neisseria meningitidis are the leading causes of bacterial meningitis.
What is Meningitis?
Meningitis is an infection of the meninges that are membranes that cover the brain and the spinal cord.
Queensland researchers have discovered that a mutation allows some E. coli bacteria to cause severe disease in people while other bacteria are harmless, a finding that could help to combat antibiotic resistance.
A group of international mycology experts led by Professor Dr Oliver A. Cornely at the University of Cologne has jointly drafted a guideline for the diagnosis and treatment of cryptococcosis, which aims at improving infection management and thus the survival rate of patients.
One in three children who suffer from bacterial meningitis live with permanent neurological disabilities due to the infection.
Researchers investigate the mechanism responsible for amphotericin B tolerance of Cryptococcus neoformans.
Metabolite-drug-fungal interactions in the fungal meningitis pathogen Cryptococcus neoformans.

Researchers from Binghamton University, State University of New York are unraveling the workings of Group B Strep (GBS) infections in pregnant women, which could someday lead to a vaccine.
Study in BioRisk explores the use of Raman spectroscopy for rapid identification of Pseudomonas aeruginosa, a bacteria causing serious human diseases, demonstrating its potential as a quick and efficient diagnostic tool.
This study in Scientific Reports reveals that symptoms of community-acquired bacterial meningitis (CABM) vary between children and adults, emphasizing the need for tailored approaches in early diagnosis and treatment to improve outcomes.
The global impact of the coronavirus pandemic has ignited a renewed focus on emerging and re-emerging infectious diseases.
A team of scientists from the Institut Pasteur has used the database of the National Reference Center for Meningococci to trace the evolution of invasive meningococcal disease cases in France between 2015 and 2022, revealing an unprecedented resurgence in the disease after the easing of control measures imposed during the COVID-19 epidemic.
The Pediatrics study analyzes trends in antiviral usage among U.S. children and adolescents with influenza, revealing significant variations in dispensing rates and costs, and low usage among children under six years, emphasizing the need for improved treatment strategies.
Scientists have found that specially processed samples of willow bark extract have an antiviral effect which isn’t seen in already known medical compounds from willow bark, such as salicylic acid, the precursor to modern aspirin.
This research paper delves into the risks of contamination in ready-to-eat fruits and vegetables by enteric pathogens like E. coli, Salmonella, and Listeria, which can lead to foodborne illnesses. It also explores the contamination sources and plant-pathogen interactions, emphasizing the importance of improved safety measures in the food supply chain.
A study in The Lancet Regional Health exposes significant gaps in the effectiveness of WHO-recommended antibiotic regimens for serious infections in Southeast Asian and Pacific children, underscoring the urgent need for region-specific treatment guidelines to combat rising antimicrobial resistance.
Drugs to treat common infections in children and babies are no longer effective in large parts of the world, due to high rates of antibiotic resistance.
