Pneumococcal Infections. Streptococcus pneumoniae(pneumococci) are gram-positive, alpha-hemolytic, aerobic,encapsulated diplococci. In the US, pneumococcal infection annuallycauses about 7 million cases of otitis media, 500,000 cases ofpneumonia, 50,000 cases of sepsis, 3,000 cases ofmeningitis, and 40,000 deaths.

Furthermore, what are Diplococci bacteria?
A diplococcus (plural diplococci) is around bacterium (a coccus) that typically occurs in the formof two joined cells. Examples of gram-negative diplococciare Neisseria spp., Moraxella catarrhalis, and Acinetobacter spp.Examples of gram-positive diplococci are Streptococcuspneumoniae and Enterococcus spp.
Beside above, how is pneumococcal disease treated? Antibiotic treatment for invasivepneumococcal infections typically includes 'broad-spectrum'antibiotics until results of antibiotic sensitivity testing areavailable. Broad-spectrum antibiotics work against a wide range ofbacteria.
Similarly, what diseases are caused by Streptococcus pneumoniae?
S pneumoniae is the most common cause ofcommunity-acquired pneumonia (CAP), bacterial meningitis,bacteremia, and otitis media, as well as an important causeof sinusitis, septic arthritis, osteomyelitis, peritonitis, andendocarditis. Complications of each of these diagnoses arecommon.
What are intracellular gram negative Diplococci?
Neisseria species are fastidious,Gram-negative cocci that require nutrientsupplementation to grow in laboratory cultures. Neisseria spp. arefacultatively intracellular and typically appear in pairs(diplococci), resembling the shape of coffeebeans.
Related Question AnswersWhat does Diplococci bacteria cause?
S. aureus can cause inflammatory diseasesincluding skin infections, pneumonia, endocarditis, septicarthritis, osteomyelitis, and abscesses. Streptococcus pneumoniaeis a gram-positive, encapsulated, lancet-shaped diplococcimost commonly causing otitis media, pneumonia, sinusitis,and meningitis.Are gram positive bacteria harmful?
As a rule of thumb (which has exceptions),Gram-negative bacteria are more dangerous asdisease organisms, because their outer membrane is often hidden bya capsule or slime layer which hides the antigens of the cell andso acts as "camouflage" - the human body recognises a foreign bodyby its antigens; if they areHow do bacteria reproduce?
Bacteria reproduce by binary fission. In thisprocess the bacterium, which is a single cell, divides into twoidentical daughter cells. Binary fission begins when the DNA of thebacterium divides into two (replicates).How do bacteria multiply?
Bacteria do not grow and multiplythe same way as animals or humans. They take in nutrients andreproduce by dividing – one bacteria splits andbecomes two bacteria, two become four, four become eight andso on. Each type of bacteria has its own preferredconditions for growth.How do we classify bacteria?
Bacteria are classified into 5 groupsaccording to their basic shapes: spherical (cocci), rod (bacilli),spiral (spirilla), comma (vibrios) or corkscrew (spirochaetes).They can exist as single cells, in pairs, chains orclusters.Is E coli cocci or bacilli?
For example, E. coli is a rod-shapedbacterium that can be described as "a bacillus", but itstains Gram-negative and does not belong to the genusBacillus or the class Bacilli. Some microbiologistshave forsaken the general "bacillus" term because of theconfusion it can create.What type of bacteria are rods?
A bacillus (plural bacilli) or bacilliformbacterium is a rod-shaped bacterium orarchaeon. Bacilli are found in many different taxonomicgroups of bacteria. However, the name Bacillus capitalizedand italicized, refers to a specific genus ofbacteria.Where are gram positive cocci found?
Staphylococcus aureus These ubiquitous gram-positive cocci arecommonly found on the skin and nasal mucosa, with 20% to 30%of the population being normal carriers of thisbacterium.Can pneumonia affect the brain?
If left untreated, the patient has severe complicationswith permanent brain damage, hearing loss, and coma.Cerebral abscess is often a complication of chronic sinus ormiddle-ear infections or the distant spread of the infection fromsomewhere else (such as a lung abscess orpneumonia).Where is Streptococcus pneumoniae found in the body?
Streptococcus pneumoniae are most commonlyfound in the human upper respiratory tract, specifically inthe nasopharynx (the nasal passages). Most people carry thesebacteria in their nasopharynx, and the harboring of S.pneumoniae within a human is called carriage.Where is pneumococcal bacteria found?
Pneumococcal infection - including symptoms,treatment and prevention. Pneumococcal infections are causedby the bacterium Streptococcus pneumoniae, also known aspneumococcus (plural 'pneumococci').Pneumococci are commonly found in the upperrespiratory tract of healthy people throughout theworld.How do you get pneumococcal disease?
Pneumococcal (noo-muh-kok-ul) disease isan infection caused by a type of bacteria called Streptococcuspneumoniae. Pneumococcal disease can cause pneumonia,bloodstream infection (sepsis), or meningitis. The bacteria spreadthrough coughing or sneezing, or through direct contact such askissing.Who is at risk for pneumococcal infection?
Children at Risk for PneumococcalDisease Children at increased risk for pneumococcaldisease include those: Younger than 2 years old. Who have certainillnesses (sickle cell disease, HIV infection, diabetes,immune compromising conditions, nephrotic syndrome, or chronicheart, lung, kidney, or liver disease)How does Streptococcus pneumoniae enter the body?
Pneumococcus bacteria are spread through coughing,sneezing, and close contact with an infected person. Symptoms ofpneumococcal disease depend on the part of the bodythat is infected.What is the most common treatment for Streptococcus pyogenes infections?
Penicillin or amoxicillin is the antibiotic ofchoice to treat group A strep pharyngitis. There hasnever been a report of a clinical isolate of group A strepthat is resistant to penicillin. However, resistance toazithromycin and clarithromycin is common in somecommunities.How do you test for streptococcus pneumoniae?
Tests generally appear in the order most useful for commonclinical situations.- Respiratory Culture and Gram Stain 0060122.
