Bacteria - Living Material

Isolated from human nasopharynx, saliva, and sputum. Spontaneously agglutinates in saline.

All microbial cultures undergo an extensive quality control program prior to releasing for sale, so they are guaranteed for purity as well as for species.

Nitrogen fixation, produces nodules on legume roots. Bacteroids from nodules can be X, Y, and club shapes.

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

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

Isolated from the alimentary tract of cows. Lancefield group D, gamma hemolysis. May be pathogenic in humans. 

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

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

Produces streptomycin. Branching mycelium and coenocytic hyphae. 

A Common Intestinal Flora Isolate, Demonstrates Alpha Hemolysis on Blood Agar Growth Medium

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

This organism can be isolated from soil, wounds, and intestinal tracts of humans. It digests protein and is known for its strong, distinctive odor.

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

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