Pneumonia is a disease of the lung that is caused by a variety of bacteria including Streptococcus, Staphylococcus, Pseudomonas, Haemophilus, Chlamydia and Mycoplasma, several viruses, and certain fungi and protozoans.
Lobar pneumonia involves all of a single lobe of the lungs (although more than one lobe may be involved), wherein the entire area of involvement tends to become a consolidated mass, in contrast to the spongy texture of normal lung tissue.
Streptococcus pneumoniae is known in medical microbiology as the pneumococcus, referring to its morphology and its consistent involvement in pneumonia This article deals with pneumonia caused by Streptococcus pneumoniae,or pneumococcal pneumonia.

Streptococcus pneumoniae is a species of Streptococcus that is a major human pathogen.
It was renamed Streptococcus pneumoniae in 1974 because of its growth in chains in liquid media.
In 1936, a pneumococcal capsular polysaccharide vaccine was used to abort an epidemic of pneumococcal pneumonia.

Streptococcus pneumoniae (pneumococcus): A type of bacterium that comes in pairs and is shaped like a lancet (a surgical knife with a short wide two-edged blade).
Pneumococcus is the leading cause of bacterial pneumonia and otitis media (middle ear infections) and an important contributor to bacterial meningitis.

 Penicillin Resistant Streptococcus Pneumoniae   (Site not responding. Last check: )
Pneumoniae is defined by the National Comittee for Clinical Laboratory Standards in America as those isolates that are only inhibited by penicillin concentrations greater than 2.0 µg/ml.
Pneumoniae is often carried asymptomatically in the nose and throat, however it may opportunistically cause a variety of infections.
Pneumoniae cause infections when the high natural resistance to them is reduced by abnormalities of the respiratory tract, intoxication with alcohol or drugs, abnormal circulation (such as heart failure or pulmonary congestion) or by various other mechanisms.

As S pneumoniae colonies age, viability is lost during fermentative growth in the absence of catalase and peroxidase because of the accumulation of peroxide.
Early-onset neonatal disease (associated with sepsis, meningitis and pneumonia at 6d life) is thought to be transmitted vertically from the mother; late-onset (from 7d to 3 mos age) meningitis is acquired horizontally, in some instances as a nosocomial infection.
Although antibiotic resistance among S pneumoniae was infrequent in the United States, a major shift occurred from 1988 to 1990, resulting in the present situation of 15-25% of S pneumoniae intermediately or completely resistant to penicillin.

 Streptococcus Pneumoniae-Pneumonia
Pneumoniae is a type of bacteria that can cause a wide rage of diseases.
If you develop pneumonia, your chances of a fast recovery are greatest under certain conditions: "if you're young, if your pneumonia is caught early, if your defenses against disease are working well, if the infection hasn't spread, and if you're not suffering from other illnesses".
Because pneumonia is a common complication of influenza (flu), getting a flu shot every fall is good pneumonia prevention.

Streptococcus pneumoniae, or pneumococcus, is a bacteria that causes many different kinds of infections in people, ranging from ear infections and sinus infections to pneumonia, meningitis, and sepsis.
Although the names (and bacterial genuses) are similar, S. pneumoniae is quite different from group A streptococcus (the bacteria that causes strep throat and rheumatic fever).
And it's a pretty common bug to be infected with: pneumococci are the most common cause of ear infections and sinus infections, as well as the most common bacteria found in the blood of children under 2 years old with fevers, many of whom have no obvious site of infection.

The capsule of Streptococcus pyogenes is chemically similar to that of it's host's connective tissue, and therefore, is nonantigenic, and it's cytoplasmic membrane has antigens similar to human cardiac skeletal and smooth muscle.
Pneumonia can be caused by a barrage of different things including viruses and fungi, but is most commonly caused by Streptococcus pneumoniae (mentioned above in the genome section) also called pneumococcus, which is the only type of pneumonia for which there is a vaccine.
pneumoniae are often present in healthy throats and only develop into a serious infection when the host's defenses are depleted due to such factors as old age, illness (i.e.

 Streptococcus pneumoniae
It is by far the most common cause of bacterial pneumonia and meningitis.
Due to Choline-Binding Proteins (CBP's), the pneumococcal cells are extremely resistant to phagocytosis, thus the growing colonies create an inflammatory response in the lungs. As the cells lyse in response to intercellular defense mechanisms and antibiotics, they release additional proteins that further increase tissue inflammation.
Symptoms of bacterial pneumonia include fever, chills, general feeling of malaise, cough, and chest pain.

Although S. pneumoniae infections involving other normally sterile sites such as joint, pleural, or peritoneal fluid are sometimes considered invasive, these infections are not intended for inclusion under this surveillance system.
Confirmed: A clinically compatible case caused by laboratory-confirmed S. pneumoniae identified as "non-susceptible" according to MIC interpretive breakpoints as outlined in NCCLS guidelines for susceptibility testing to any antimicrobial agent currently approved for use in treating pneumococcal infection*.
Comment: NCCLS recommends that all invasive S. pneumoniae isolates that are found to be "possibly resistant" to beta-lactams (i.e., an oxacillin zone size of <20mm) by oxacillin screening should undergo further susceptibility testing using a quantitative MIC method acceptable for penicillin, extended spectrum cephalosporins, and other drugs as clinically indicated.
