Streptococcus pneumoniae Ag [Presence] in Cerebral spinal fluid by Latex agglutination

Active

Part Description

LP14410-2 Streptococcus pneumoniae
Streptococcus pneumoniae are gram-positive cocci that are nonmotile and nonsporulating and usually require complex culture media. Older streptococcal cultures, beyond the most active growth period (the logarithmic phase), sometimes lose their gram-positive staining characteristics. S. pneumoniae are part of the normal respiratory tract flora. Disease usually results due to the acquisition of a new strain following a change in the normal flora, often due to a preceding virus. S. pneumonaie causes otitis media, sinusitis and pneumonia in the middle ear, sinuses or lungs, respectively. Meningitis can occur by bloodstream invasion from the lungs or by extension of otitis media or sinusitis to the meninges. Bacteremia can result in osteomyelitis (infection of bones) or arthritis (of joints). Most bacterial pneumonia occurring after the neonatal period is caused by S. pneumoniae. Pneumococcal pneumonia is seen most commonly in elderly or immunosuppressed individuals. In the United States, it is most prevalent in winter. Diagnosis is usually based on a sputum Gram stain and culture although blood or cerebrospinal fluid may be cultured. While penicillin has been the standard treatment, some strains have proven resistant to penicillin and multiple antibiotics. A vaccine exists. [NCBI Books:NBK7611] Source: Regenstrief LOINC
