A spherical, gram-positive bacterium of the genus Streptococcus. Although commonly found benignly in the human mouth and gut, and though many species are non-pathogenic, other species can cause diseases including strep throat and more serious conditions.
A spherical gram-positive parasitic bacterium of the genus Staphylococcus, causing blisters, septicemia, and other infections
A long or short chain of micrococci, more or less curved.
spherical gram-positive parasitic bacteria that tend to form irregular colonies; some cause boils or septicemia or infections
spherical gram-positive bacteria occurring in pairs or chains; cause e.g. scarlet fever and tonsillitis
Staphylococcus is a genus of Gram-positive bacteria in the family Staphylococcaceae from the order Bacillales. Under the microscope, they appear spherical (cocci), and form in grape-like clusters.
Streptococcus is a genus of gram-positive coccus (plural cocci) or spherical bacteria that belongs to the family Streptococcaceae, within the order Lactobacillales (lactic acid bacteria), in the phylum Firmicutes. Cell division in streptococci occurs along a single axis, so as they grow, they tend to form pairs or chains that may appear bent or twisted.
