Which bacteria is responsible for bacterial meningitis?
Streptococcus pneumoniae (pneumococcus). This bacterium is the most common cause of bacterial meningitis in infants, young children and adults in the United States. It more commonly causes pneumonia or ear or sinus infections. A vaccine can help prevent this infection.
What types of cells cause meningitis?
The most common types of bacteria that cause bacterial meningitis are: Streptococcus pneumoniae, which is typically found in the respiratory tract, sinuses, and nasal cavity and can cause what’s called “pneumococcal meningitis”
How does meningitis attach to host cells?
The initial interaction between the meningococcus and the host cell is mediated through the meningococcal type IV pilus. The meningococcus then retracts the pilus bringing the bacterium into close contact with the host cell surface [17].
Which bacteria is the cause for meningococcal meningitis?
Meningococcal disease refers to any illness caused by bacteria called Neisseria meningitidis, also known as meningococcus [muh-ning-goh-KOK-us]. These illnesses are often severe and can be deadly.
Which cells are responsible for removing meningitis?
Microglia, which are the brain’s immune system cells, are involved in everything – from brain development to protecting against diseases such as meningitis and Alzheimer’s.
What is bacterial meningitis?
Bacterial meningitis is the most serious type of meningitis. It can lead to death or permanent disability. It is a medical emergency. Meningitis affects the meninges, the membranes that surround the brain and spinal cord and protect the central nervous system (CNS), together with the cerebrospinal fluid.
Where is bacterial meningitis most commonly found?
Meningococcal disease occurs worldwide, with the highest incidence of disease found in the ‘meningitis belt’ of sub-Saharan Africa. In this region, major epidemics occur every 5 to 12 years with attack rates reaching 1,000 cases per 100,000 population.
How is bacterial meningitis transmitted?
People spread meningococcal bacteria to other people by sharing respiratory and throat secretions (saliva or spit). Generally, it takes close (for example, coughing or kissing) or lengthy contact to spread these bacteria. Fortunately, they are not as contagious as germs that cause the common cold or the flu.
Is meningitis bacterial or viral?
Meningitis is usually caused by a viral or bacterial infection. Viral meningitis is the most common and least serious type. Bacterial meningitis is rare, but can be very serious if not treated.
Which organism can cause epidemic meningitis?
Several different bacteria can cause meningitis. Streptococcus pneumoniae, Haemophilus influenzae, Neisseria meningitidis are the most frequent ones. N. meningitidis, causing meningococcal meningitis, is the one with the potential to produce large epidemics.
How does meningitis affect the cells?
Your spinal fluid will have high protein levels and an increased white blood cell count if you have meningitis. This fluid can also help your doctor determine whether bacteria, viruses, or other infectious agents are causing the meningitis.
