Streptococcus Pneumoniae also referred to as pneumococcus is responsible for the maximum types of pneumonia in human beings. The infection that this bacterium causes could be dangerous and could pave way for a variety of life-threatening diseases. 2021-02-04 · Virulence factors, Pathogenesis and Clinical manifestations of Streptococcus pneumoniae. S. pneumoniae colonizes the oropharynx by adhering to the epithelial cells of pharynx. Pneumonia is a leading cause of death, especially in older adults and those whose resistance is impaired.

Usually, they are seen as pairs of cocci (diplococci), but they may also occur singly and in short chains.

Melike Ekizoğlu PhD, in Nanotechnology Methods for Neurological Diseases and Brain Tumors, 2017. Etiology of Bacterial Meningitis. The most common causative organisms of acute bacterial meningitis are Streptococcus pneumoniae (also called Pneumococcus), Streptococcus agalactiae, Neisseria meningitidis (also called Meningococcus), and Listeria monocytogenes. 19,20

Streptococcus pneumoniae are lancet-shaped, gram-positive, facultative anaerobic bacteria with 100 known serotypes. Identification and Characterization of Streptococcus pneumoniae. S. pneumoniae may occur intracellularly or extracellularly as gram-positive lanceolate diplococci, but can also occur as single cocci or in short chains of cocci. S. pneumoniae is a fastidious bacterium, growing best at 35-37°C with ~5% CO 2 (or in a candle-jar).

Ex: TSA supplemented with 5% sheep’s blood. Genus Streptococcus: habitat, morphology, culture and biochemical characteristics The genus streptococcus include a large number of species of Gram +ve, catalase –ve cocci arranged in chain of varying length and also in pairs. Streptococcus pneumoniae (the pneumococcus) is the classic example of a highly invasive, Gram-positive, extracellular bacterial pathogen. It is a major cause of morbidity and mortality globally causing more deaths than any other infectious disease. MORPHOLOGY Small, slightly elongated cocci One end broad or rounded and the other pointed Flame shamed or lanceolate Pairs with broad ends in apposition Capsulated Typical morphology may not occur in culture India ink preperation 2017-09-06 In this study, we report the isolation of colony morphology variants from Streptococcus pneumoniae serotype 3 biofilms.

The colony variants differed in colony size (large, medium, and small) and their mucoid appearance on blood agar.

From 1985 to 1987, Streptococcus pneumoniae isolates were collected from children under 5 years of age in the Asaro Valley, Papua New Guinea as part of a study on bacterial colonization and respiratory tract infections. Data on serogroup and colony morphology were collected to survey serogroups and associated colony morphologies present in the area and to assess whether colony morphology can

Patients usually develop a meningitis via hematogenous dissemination of the bacteria. Streptococcus pneumoniae is also responsible for meningitis via direct spread from the nasopharyngeal niche to the central nervous system (CNS). Direct entry through dural defects is possible. MORPHOLOGY OF STREPTOCOCCUS PNEUMONIAE (PNEUMOCOCCUS) 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). 2021-02-04 · Morphology of Streptococcus pneumoniae They are gram positive bacteria. May lose gram +ve character in older cultures and appear gram –ve.
