Everything you need to safetly collect and culture bacteria and fungi from your environment

Ward's® Live Escherichia coli, Lactose Negative Culture

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

Isolated from human nasopharynx. Presumably not related to N. sicca; some relation to N. gonorrhoeae. Often agglutinates in saline. 

Produces streptomycin. Branching mycelium and coenocytic hyphae. 

E. coli with JM101 can be transformed with pUC8 plasmid to become resistant to Ampicillin and to metabolize lactose

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

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

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

Normal flora of respiratory tract. Beta-lactamase positive. Also known by the name Branhamella catarrhalis

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

A collection of some of the strains of Escherichia coli needed to grow various coliphages (available separately).

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

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.

Freshwater. Filamentous. True branching, dimorphic structure. Basic culture solution.

Shipped in a form that provides the best quality specimen. Most are supplied in 16 x 125 mm tubes, 2 oz. jars, or 8 oz. jars..
