Micoorganisms That Are Spherelike & Flowerlike

Streptococcus Pneumoniae

• Streptococcus pneumoniae are spherical bacteria that divide in one plane, producing a linked, streptococcus arrangement. This type of bacteria strain is responsible for causing several illnesses, such as pneumonia, otitis media, meningitis, sinusitis, peritonitis and arthritis. There are more than 90 different strains of this bacteria.

Streptococcus Pyogenes

• Streptococcus pyogenes is another spherical bacteria that divides in one plane to produce a streptococcus arrangement. This bacteria is the cause of rheumatic fever. Acute rheumatic fever causes heart disease in children of Third World countries.

Neisseria

• Neisseria is bacteria that divides into pairs in one plane, creating a diplococcus arrangement. These bacteria inhabit mucosal surfaces of the human body, particularly the genital areas. Neisseria gonorrhoeae causes the sexually transmitted disease gonorrhea. Neisseria meningitidis is the diplococcus bacteria responsible for the central nervous system disease meningitis.

Staphylococcus

• Staphylococcus are spherical bacteria that are arranged in irregular clusters. Some describe this type of bacteria as grapelike or flowerlike clusters. Staphylococcus aureus is one such bacterium that produces a toxin that causes food poisoning in humans.

Sarcina and Tetrad Species

• Sarcina bacteria are spherical bacteria that do not separate after they divide and form in cubes of eight. Tetrad bacteria are spherical bacteria that also do not separate after division and form in cubes of four. Both types of bacteria normally inhabit the human body. They don't cause illness unless there are too many of them or they inhabit atypical parts of the body.
