"Ward's Science"

Predatory. Feeds on Paramecium caudatum. Hay medium.

Characterized by cilia; nearly all possess two types of nuclei.

The body of this ciliate is transparent, making the large cilia clearly visible.

Live Cultures are supplied with media in 16 x 125 mm tubes, 2 oz. jars, or 8 oz. jars. Fast delivery is available directly from our laboratory. Please specify a delivery date.

Each culture shipment is prepared in our laboratories and includes the "Working with Protozoans" manual which contains detailed instructions for subculturing and use.

Canadian Customers:
CFIA and PHAC regulations require customers to submit a completed inspection checklist and signed statement of facilities compliance before receiving certain cultures. A customer service representative will contact you if documentation is required.

Our cultures undergo strict biochemical screening and are unconditionally guaranteed for species and purity. Each culture is labeled with scientific name, media on which it was cultivated and optimum growth temperature. Although our cultures are considered non-pathogenic, standard bacteriological laboratory procedures should be used at all times. Cultures are available either live for immediate use or freeze-dried for convenient storage until needed. (Please note: We are not responsible for any infection resulting from the use of our cultures.)

With stiff 'arms' radiating in all directions, these microscopic organisms look like sea urchins

Volvox aureus is a species of colonial green algae that forms spherical colonies of cells.

Freshwater. Filamentous; two stellate chloroplasts per cell. Basic culture solution.

Characterized by green plastids and cell walls composed of cellulose.

Freshwater, Unicellular; pennate, with bilateral symmetry. Diatom or basic medium.

Characterized by shells (tests) made of silica, in two parts.

Freshwater; elongated, biflagellate cells that form globular colonies; gelatinous sheath absent.

Marine; Small Motile Cells with the Transverse Furrow Located Near the Apex.

Freshwater. Unicellular. Soil-water medium. Characterized by two flagella (one inside a groove at right angles to the other); most also have tests made of cellulose and are encrusted with silica.

Usually found in freshwater and mosses, this organism has a hard umbrella shaped shell or "test", out of which finger-like pseudopodia project.

Marine. Filamentous; freely branched. Erdschreiber’s medium.

Characterized by green plastids and cell walls composed of cellulose.

Very large ciliate. Feeds on colpidium. Hay medium.
Characterized by cilia; nearly all possess two types of nuclei.

Paramecium caudatum is a common protist that inhabits a variety of aquatic ecosystems.

This organism is easily recognized by its trumpet-shape, and can commonly be found in freshwater ponds and streams. It reproduces by budding.

Freshwater. Colonial; with spherical, biflagellated cells. Basic culture solution.

Characterized by green plastids and cell walls composed of cellulose.

Freshwater; forms a colony of four, eight, 16 or 32 cells.
