Factsheet about pneumococcal disease. Pneumococcal diseases are symptomatic infections caused by the bacterium Streptococcus pneumoniae (S. pneumoniae), commonly referred to as pneumococci. The term invasive pneumococcal disease (IPD) is used for more severe and invasive pneumococcal infections, such as bacteraemia, …What is an invasive Streptococcus pneumoniae infection?. Streptococcus pneumoniae are bacteria that are commonly found in the nose and throat of children and adults. S. pneumoniae can infect the lungs (pneumonia) or ears (otitis media), but it is considered "invasive" when it is found in the blood, spinal fluid (e.g., meningitis), or other site that normally does not have bacteria present.1. Introduction. Streptococcus pneumoniae is a major cause of community-acquired pneumonia and meningitis worldwide, particularly in low- and middle-income countries ().Although all age groups are affected, the highest incidence rates of pneumococcal disease occur in young children and older adults (1, 2).Pneumococcal bacteria also frequently colonize the respiratory tract of asymptomactic ...Many conditions increase disease risk.

Asymptomatic nasopharyngeal carriage of pneumococcus and Hib was determined for healthy children in Shanghai in 2009.Background. Pneumococcal endocarditis (PE) has become uncommon since the advent of penicillin; it now develops in less than 1% of native heart valves 1.However, an increase in the number of prosthetic heart valves as a predisposing factor for PE has recently been observed, accounting for 22-31% of all cases of valve endocarditis 2.Furthermore, many cases of penicillin‐resistant ...A sore throat can be a real pain.

Among the S. pneumoniae isolates, a statistically significant connection was found between regional consumption ...Streptococcus pneumoniae (the pneumococcus) is a Gram-positive bacterium and the predominant cause of bacterial meningitis. Meningitis is thought to occur as the result of pneumococci crossing the blood-brain barrier to invade the Central Nervous System (CNS); yet little is known about the steps preceding immediate disease development.

Pneumococcal disease can affect many different systems in your body. It may result in conditions with mild symptoms like a sinus infection (sinusitis). But it can also lead to pneumonia, blood infection (sepsis) or bacterial meningitis — and may be life-threatening at any age.
