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.
According to a research work published in the Genome Medicine journal, travelers abroad may contract bacteria and other vectors with genes that confer antibiotic resistance, which linger in the travelers’ gut when they return home.
Professor Frédéric Veyrier of the Institut national de la recherche scientifique (INRS) has received $711,450 from the Canadian Institutes of Health Research (CIHR) for a project on bacteria of the nasopharynx, including Neisseria.
Synthetic cannabidiol, commonly called CBD, has been demonstrated to destroy the bacteria that cause meningitis, gonorrhea, and Legionnaires’ disease.
Researchers at the University of Maryland School of Medicine published one of the most comprehensive analyses of how genes get expressed during infection (known as a transcriptome).
Researchers have designed a laboratory test that can detect the microbial miscreant affecting patients hospitalized with serious infections in just six hours.
Recently, researchers explained that infection by certain enteroviruses could possibly activate diabetes.
For the first time, researchers have discovered how antibiotic resistance genes are spreading, at a continental scale, via bacterial plasmids in the hospital superbug, Klebsiella pneumoniae.
Antibiotics are among the most important discoveries of modern medicine and have saved millions of lives since the discovery of penicillin almost 100 years ago.
Meningococci are bacteria that can cause life-threatening meningitis and sepsis. These pathogens use a small protein with a large impact: The RNA-binding protein ProQ is involved in the activation of more than 250 bacterial genes.
