Frequent human isolate. Causes gastroenteritis.

Ames test strain for detecting carcinogens. Causes infection in humans. 

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

From sewage and human intestine. Causes dysentery. 

isolated from human intestine. Lactose positive and sucrose positive after a few days’ growth. Causes a mild form of dysentery.

Beta hemolysis on blood. Causes wound infections and septicemia. 

Grows on dead tissues. Novobiocin resistant (S. epidermidis and S. aureus novobiocin sensitive). 

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.

Found on dental plaque, implicated in cavities. No Lancefield group shown, gamma hemolysis. 

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

Normal flora of the mouth and throat. Lancefield group K, gamma hemolysis. 

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

This organism is normal flora of human intestine and may be pathogenic in humans. This organism will grow in Sodium chloride solution.

The presence of A. viscolactis in milk is a common cause for sliminess or "ropiness".

This pathogenic organism is sometimes isolated from hay and grass.

This organism is occasionally isolated from soil, but most frequently from smegma- a secretion from male and female genitalia.
