Bacterial Tests

Coliform bacteria are common environmental bacteria, typically associated with the mammalian digestive tract. Although not generally pathogenic themselves, coliforms are a well-known marker of fecal contamination, and their presence is interpreted to suggest that potentially pathogenic bacteria may be present. This test detects both E. coli and coliform bacteria and is adapted from the Health […]

This test determines the presence of airborne culturable thermophilic actinomycetes and expresses the result in Colony Forming Units per Cubic Metre of air (CFU/m³). Actinomycetes are a large and diverse group of Gram-positive bacteria that have growth habits similar to fungi in that they produce branching networks of filaments. Thermophilic actinomycetes occur in a wide […]

This test determines the presence of airborne culturable psychrophilic actinomycetes and expresses the result in Colony Forming Units per Cubic Metre of air (CFU/m³). Actinomycetes are a large and diverse group of Gram-positive bacteria that have growth habits similar to fungi in that they produce branching networks of filaments. Psychrophilic actinomycetes grow optimally at low […]

This test determines the presence of airborne culturable mesophilic actinomycetes and expresses the result in Colony Forming Units per Cubic Metre of air (CFU/m³). Actinomycetes are a large and diverse group of Gram-positive bacteria that have growth habits similar to fungi in that they produce branching networks of filaments. Mesophilic actinomycetes occur in a wide […]

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. […]
