Isolated from sewage, human intestines, and urinary tract infections. Spreading colonies are seen on agar growth medium. 

Lancefield group A, beta hemolysis. Sensitive to bacitracin. Causes strep throat, rheumatic fever, and scarlet fever.

This organism is a common inhabitant of intestinal flora, and can be a major cause of urinary tract infection.

This spore-forming, thermophilic organism is commonly used for germicidal and sporicidal testing due to its ability to withstand higher-than-normal temperatures.

Both of these strains of Serratia marcescens are colorless mutants when plated alone, but when grown together, they produce a red pigment.

No Lancefield group shown, alpha hemolysis. Bile solubility test positive, optochin sensitive. Causes pneumonia. 

This yellow, shiny organism is known to cause wound infections and more famously, toxic shock syndrome.

Kocuria rhizophila is also commonly known by the name Micrococcus luteus. This organism is commonly isolated from soil, and is frequently used to test antimicrobial efficacy in the food industry.

This organism is commonly isolated from soil, and depending upon the temperature of its environment, can produce a distinctive red pigment.

Hemolysis, the rupture of red blood cells, is induced by certain species of streptococcal bacteria that produce extracellular hemolysin.  Observe this phenomenon with this set of 3 non-pathogenic species
