Streptococcus pneumoniae
Test code:
B0001
- Qualitative detection of
Streptococcus pneumoniae
by polymerase chain reaction.
Streptococcus pneumoniae
is gram-positive, alpha-hemolytic, bile-soluble aerotolerant
anaerobe. Besides pneumonia, this organism causes many other
types of infection, such as acute sinusitis, otitis media,
meningitis, bacteremia, sepsis, osteomyelitis, septic arthritis,
endocarditis, peritonitis, pericarditis, cellulitis, and brain
abscess.
S. pneumoniae
is the most common cause of bacterial meningitis in humans, and
is one of the two most prevalent isolates found in ear
infection, otitis media. Several animal species, including
rodents, dogs and monkeys, can also be infected with these
bacteria.
Culture detection of S.
pneumoniae is not very sensitive compared to
molecular detection by PCR. In addition, PCR is much more
specific and rapid than culture (Virolainen et al., 1994).
Utilities:
-
Help confirm
the disease causing agent
-
Shorten
the time required to confirm a clinical diagnosis of
S. pneumoniae
infection.
-
Help ensure
that colonies are free of
S. pneumoniae
-
Early
prevention of spread of this bacterium
-
Minimize
personnel exposure to this bacterium
-
Safety
monitoring of biological products that derive from primates

Specimen requirements:
0.2 ml whole blood in EDTA (purple top) tube, or
serum, pleural fluid, CSF or bacterial culture; or 0.1 ml fresh,
frozen or fixed tissue.
Contact Zoologix if advice is needed to determine an appropriate specimen type for a specific diagnostic application. For specimen types not listed here, please contact Zoologix to confirm specimen acceptability and shipping instructions.
For all
specimen types, if there will be a delay in shipping, or during
very warm weather, refrigerate specimens until shipped and ship
with a cold pack unless more stringent shipping requirements are
specified. Frozen specimens should be shipped so as to remain
frozen in transit. See shipping
instructions for more information.
