2. Pneumococcus
(Streptococcus pneumoniae)
is a type of bacteria from
the genus (Streptococcus),
a stationary lancet
diplococcus 0.5-1.25
microns. Streptococcus
pneumoniae - gram-positive
3. There are at least 91
different capsules of
pneumococcal, but most
(more than 90%) are found
to be in the invasive disease
is caused by 23 serovars
4. Serovars it (serotype)
are a group of
microorganisms of the
same species, united by a
common antigenic
structure, determined by
serological diagnostic
methods
6. Pneumococci are paired
oval coccys, slightly
elongated lancet-shaped,
resembling the flame of a
candle. They can also be
placed in short chains,
resembling streptococcus
7. In the human body and
animals form a capsule; it
is not available when
grown on artificial
environments. Immobile,
the dispute does not form,
grampositive
