"live microorganism"

Noted for capsular swelling. Causes pneumonia and urinary tract infections.

Isolated from human urinary tract and wound infections, this organism is identifiable by its characteristic putrefactive odor. 

Red-pigmented halophile from evaporating salt ponds; requires 25% salt medium, lyses easily in plain water, releasing DNA.

This organism is an aerobic organism that is commonly found as part of normal human intestinal flora. It is pathogenic.

Observe a relationship between two organisms that together produce an effect they could not achieve individually.

Isolated from milk and udders of cows. Lancefield group B, beta hemolysis. Causes infection of the female genital tract, maternal septicemia, neonatal infections. Camp test positive; resistant to bacitracin.

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.

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. 

Lancefield group C, beta hemolysis. Causes strangles in horses. May be pathogenic in humans. Camp test negative; resistant to bacitracin, does not ferment lactose.

This organism is commonly isolated from soil or water, and produces a pink or rose colored pigment.

Isolated from human saliva, sputum, and intestine. No Lancefield group shown, alpha hemolysis.

This organism is often times isolated from food; in large amounts it can cause food poisoning
