Shape. As mentioned, For Streptococcus pneumoniae, as is the case with the other diplococci bacteria, division occurs in the parallel plane perpendicular to the long axis. During cell division, the site of division is first marked by the equatorial ring (also known as the wall band). The shape of Stretococcus pneumoniae is also diplococci, but it has also been called "lancet shaped", which means longer cocci with an outer curvature. Streptococcus pneumoniae and Neisseria meningitidis are two very similar bacteria; evidence of this would be their shape … Streptococcus Pneumoniae Pneumococci are gram-positive lancet-shaped cocci arranged in pairs S. Pneumoniae also have Pneumolysin which is a pore-forming toxin that causes We have 1 representative from each gram reaction and shape that is a respiratory organism (four in total): 1. 2003-03-01 Pneumococcal Disease Wenger et al., J Infect Dis, 1990 Pathogenic agents in bacterial meningitis in persons aged 60 years in the USA Others 26% Streptococcus pneumoniae 49% Group B streptococcus 3% Haemophilus influenzae 4% Neisseria meningitidis 4% Listeria monocytogenes 14% 14.

Streptococcus Bacteria Classification, Shape, Infection & Gram Stain Overview. Streptococcus bacteria is Gram-positive and are generally spherical in shape. They are commonly found in the mucous membrane of the mouth and respiratory tract etc where they have been associated with a number of diseases and infections including sepsis, pneumonia, and pharyngitis. Laboratory diagnosis.

Streptococcus pneumoniae are lancet-shaped, gram-positive, facultative anaerobic bacteria with 100 known serotypes. Most S. pneumoniae serotypes can cause disease, but only a minority of serotypes produce the majority of pneumococcal infections.

In throat swabs Streptococcus pneumoniae can occur in its avirulent form (oropharyngeal carriage of pneumococci is common and they are considered to be part of normal flora).

Shape – Streptococcus pneumoniae is an elongated round shape (coccus) bacterium with one end broad or rounded and the other end is pointed (flame shape or lanceolate appearance). Size – The size of Streptococcus pneumoniae is about 1 mm (micrometer).
