Gram stain & morphology [GSM]
This is an add-on test that provides further characterization of cultured bacterial contaminants according to Gram stain reaction and cell morphology. This test may be indicated when heterotrophic plate count (HPC) tests yield positive results. In this event, the laboratory will contact you and determine if you would like to add this level of characterization. […]
Culture Media
A number of environmental sampling methods exist that allow samples to be taken directly on culture media. The most common methods are viable air samplers such as RCS and Andersen samples as well as contact surface slides. If proprietary sampling media are used, ensure that the expiry date is current. In accordance with our internal […]
Bulk & Tape Lift Samples
Samples must be submitted in clearly labeled specimen bags or other suitable packet with one sample only per packet. Multiple sample packets should be sealed together inside an envelope or box with a completed sample submission form attached. Any bulk materials that are damp or moist must be contained in a water-proof packet. Damp materials […]
Phytoplasma [PHYTO]
Phytoplasmas are bacteria-like organisms without cell walls, discovered in 1967 from the phloem of members of the genus Aster manifesting symptoms of “yellows” disease. They belong to the class Mollicutes, along with mycoplasmas, spiroplasmas and other animal parasites, saprophytes, and insect commensals, and affect more than 700 plant species in all continents, many of which […]
