Author information: (1)Department of Biology, Indiana University Bloomington, Jordan Hall, Room 142, Bloomington, IN 47405, USA. Privacy & Trust Info Pneumococcus (Streptococcus pneumoniae): Are Gram-positive bacteria in the shape of a slightly pointed cocci. They are usually found in pairs (diplococci), but are also found singly and in short chains. 2020-01-14 Colin C. Kietzman, Jason W. Rosch, in Streptococcus Pneumoniae, 2015 Copper. Pneumococci also encode an operon dedicated to the efflux of copper from the bacterial cytoplasm.

Most people carry these bacteria in their nasopharynx, and the harboring of S. pneumoniae within a human is called carriage. 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.

Laboratory diagnosis of Streptococcus pneumoniae infection is based on finding characteristics shape of the organism in the sputum, characteristic colony morphology, biochemical reactions, susceptibility to certain diagnostic discs and latex agglutination test. Streptococcus pneumoniae is a Gram positive cocci, typically lancet shaped and occurs singly, in pairs (diplococci) or in short chains. Streptococcus pneumoniae in Gram Staining.

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.

Scientific Name: Streptococcus Pyogenes Common Name: Strep Throat Description: A ball shaped bacterium that causes Strep Throat. The organisms are Both staphylococci and streptococci have round, spherical cell shape, but the Streptococcus pneumoniae: Inhibited by Optochin (ethyl hydrocupreine). STREPTOCOCCUS PNEUMONIAE (PNEUMOCOCCUS). • Gram-positive, nonmotile, encapsulated cocci.

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). It is usually Streptococcus pneumoniae resides asymptomatically in healthy carriers typically colonizing the respiratory tract, sinuses, and nasal cavity.However, in susceptible individuals with weaker immune systems, such as the elderly and young children, the bacterium may become pathogenic and spread to other locations to cause disease. Morphology of Streptococcus pneumoniae They are gram positive bacteria. May lose gram +ve character in older cultures and appear gram –ve. They are non-sporing and non-motile bacteria. Streptococcus pneumoniae (pneumococcus): A type of bacterium that comes in pairs and is shaped like a lancet (a surgical knife with a short wide two-edged blade).

Streptococcus pneumoniae in Gram Staining. Main diseases caused by Streptococcus pneumoniae: Bacterial pneumonia: Most common bacterial cause, especially in … Streptococcus pneumoniae are aerotolerant (can exist in an environment with O 2) and features an anaerobic metabolism (therefore, it does not require O 2). As these colonies age, the organism loses it’s ability to obtain catalyze and peroxidase because of its accumulation of hydrogen peroxide over time (Patterson, 1996). 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.

22.2: Bacterial Infections of the Respiratory Tract Moraxella catarrhalis 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. Pneumococci are common inhabitants of the respiratory tract. Streptococcus pneumoniae, or pneumococcus, is a Gram-positive, spherical bacteria, alpha-hemolytic (under aerobic conditions) or beta-hemolytic (under anaerobic conditions), facultative anaerobic member of the genus Streptococcus. They are usually found in pairs (diplococci) and do not form spores and are non motile.

Streptococcus pneumoniaehas a complex cell wall that plays key roles in cell shape maintenance, growth and cell division, and interactions with components of the human host. The peptidoglycan has a heterogeneous composition with more than 50 subunits (muropeptides)-products of several peptidoglycan-modifying enzymes.

Transmission of Streptococcus pneumoniae occurs through. Direct person-to-person contact via respiratory droplets; Autoinoculation in persons carrying the bacteria in their upper respiratory tract; The pneumococcal serotypes most often responsible for causing infection are those most frequently found in carriers.

This seemingly innocuous state of colonisation is a dynamic and competitive process in which the pathogen attempts to engage the host, proliferate, and invade the lower airways. Biochemical Test and Identification of Streptococcus pneumoniae. They are gram +ve, catalase -ve, oxidase -ve, non-sporing, diplococci bacteria. Streptococcus agalactiae, or group B streptococcus bacteria, can cause infections of the bladder and uterus in pregnant women; in newborn infants infection with the bacterium may result in sepsis (blood poisoning), meningitis (inflammation of the membranes covering the brain and spinal cord), or pneumonia.
