- Symptoms of the disease include sudden chill, fever, cough, pleuritic pain, or sputum with a red/brown rusty color. Microbiological characteristics. Streptococcus pneumoniae is a gram-positive coccus. Usually they are found in pairs of cocci, or diplococci, but they may also occur in short chains or singly. When cultured on blood agar they demonstrate alpha hemolysis.

Coccus Written By: Streptococcus (genus Streptococcus), group of spheroidal bacteria belonging to the family Streptococcaceae. The term streptococcus (“twisted berry”) refers to the bacteria’s characteristic grouping in chains that resemble a string of beads. Streptococci are microbiologically characterized as gram-positive and nonmotile.

Coccus (def) The cocci are spherical or oval bacteria having one of several distinct arrangements (see Fig. 1) based on their planes of division. a. Division in one plane produces either a diplococcus or streptococcus arrangement.

- bacteria: Diversity of structure of bacteria. Individual bacteria can assume one of three basic shapes: spherical (coccus), rodlike (bacillus), or curved (vibrio, spirillum, or spirochete). Considerable variation is seen in the actual shapes of bacteria, and cells can be stretched or compressed in one dimension.

Examples of bacilli include Bacillus anthracis, the bacterium that causes anthrax, and the well known E. coli.

Cocci Bacteria: Spherical Shaped Bacteria Two joined cocci are known a diplococci, while four arranged in a square shape are called a tetrad. The Sarcina genus arrange themselves in groups of eight, in a cube shape. The other common arrangements include a chain of bacteria (known as streptococci) or irregular clusters of bacteria (known as staphylococci). The average size of a coccus bacterium is 0.5 - 1 micrometer.

Bacterial cellular morphologies A coccobacillus (plural coccobacilli) is a type of rod-shaped bacteria. The word coccobacillus reflects an intermediate shape between coccus (spherical) and bacillus (elongated).Coccobacilli rods are so short and wide that they resemble cocci. Haemophilus influenzae and Chlamydia trachomatis are coccobacilli. coccus (plural cocci, from the Latin coccinus (scarlet) and derived from the Greek kokkos (berry)) is any microorganism (usually bacteria) whose overall shape is spherical or nearly spherical. Describing a bacterium as a coccus, or sphere, distinguishes it from bacillus, or rod.

Eubacteria The bacteria come in a number of distinct shapes as well. Common shapes include spherical (coccus), cylindrical (rod), and spiral forms (spirilla). While bacteria are generally regarded as unicellular organisms, there are also examples of bacteria that exist as multicellular colonies, aggregates, or filaments.

Streptococcus pneumoniae 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. Pneumococcus is the leading cause of bacterial pneumonia and otitis media (middle ear infections) and an important contributor to bacterial meningitis.

Bacterial Cell Morphology and Classification: Definition, Shapes & Arrangements 'Strepto-' refers to long chains and '-coccus' refers to a spherical cell. So the strep throat bacteria Streptococcus forms long chains of cocci. If the dividing bacteria form an irregular, grape-like cluster, the prefix staphylo-is added. So members of the Staphylococcus form clusters of cocci.

Staph Infection (Staphylococcus Infection) Staphylococcus bacteria (also termed staph) are responsible for a number of common infections. Staphylococcus is a genus of bacteria that is characterized by a round shape (coccus or spheroid shaped), Gram-stain positive, and found as either single cells, in pairs, or more frequently, in clusters that resemble a bunch of grapes.
