Bacteria - Living Material
Live specimens are used for a wide variety of studies including studying the physiological effects of drugs on a specimen’s heartbeat and temperature on metabolism, the locomotion of microscopic organisms, and studying plant respiration, photosynthesis, plosmolysis, and more. Algal cultures form colonies of cells that are extremely easy to visualize for better understanding of cell walls and plastids, and many live specimens reproduce rapidly for quick turnover between successive tests.
Ward's® Live Citrobacter freundii Culture
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.
Corynebacterium diphtheriae
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.
Ward's® Live Corynebacterium pseudodiphtheriticum Culture
This organism is commonly isolated from human nasopharyngeal mucosa
Ward's® Live Corynebacterium xerosis Culture
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.
Ward's® Live Enterobacter cloacae Culture
This organism is commonly isolated from sewage, water, soil and dairy products, as it is a normal part of intestinal flora.
Ward's® Live Geobacillus stearothermophilus Culture
This spore-forming, thermophilic organism is commonly used for germicidal and sporicidal testing due to its ability to withstand higher-than-normal temperatures.
Ward's® Live Klebsiella pneumoniae Culture - PATHOGEN
Noted for capsular swelling. Causes pneumonia and urinary tract infections.
Ward's® Live Lactobacillus casei Culture
Isolated from milk and cheese products. Can be used to ferment milk.
Ward's® Moraxella catarrhalis
Normal flora of respiratory tract. Beta-lactamase positive. Also known by the name Branhamella catarrhalis
Ward's® Live Neisseria sicca Culture
Isolated from human nasopharynx, saliva, and sputum. Spontaneously agglutinates in saline.
Ward's® Live Novosphingobium capsulatum (Flavobacterium capsulatum) Culture
Capsules produced in milk. Psychrophilic (prefers low temperatures), produces yellow pigments.
Ward's® Live Proteus mirabilis Culture - PATHOGEN
Isolated from sewage, human intestines, and urinary tract infections. Spreading colonies are seen on agar growth medium.
Ward's® Live Salmonella enteritidis Culture - PATHOGEN
Frequent human isolate. Causes gastroenteritis.
Ward's® Live Salmonella typhimurium, Ames Test Strain Culture - PATHOGEN
Ames test strain for detecting carcinogens. Causes infection in humans.
Ward's® Live Serratia marcescens Cultures: Strain 933 and Strain WCF
Both of these strains of Serratia marcescens are colorless mutants when plated alone, but when grown together, they produce a red pigment.
