Endotoxin is a lipopolysaccharide found in the cell membranes of Gram-negative bacteria. Endotoxin is a strongly proinflammatory material because of its interactions with receptors that stimulate the innate immune system. Exposure to endotoxin will initiate a strong inflammatory response in anyone and does not require allergic sensitization or individual sensitivity. Inhalation exposure to endotoxin is […]

This test provides a low-level identification of a single bacterial isolate by sequencing of portions of the 16S ribosomal small subunit gene region. DNA-based sequence identification is the gold-standard for microbial identification, since it is capable of identifying rare or atypical isolates of bacteria irrespective of their responses to diagnostic culture media or biochemical tests. […]

This test determines the presence of culturable thermophilic actinomycetes in bulk and swab samples. Test results are provided semiquantitatively as 1+, 2+, 3+, etc., where the number preceding the “plus sign” indicates the order of magnitude of colonies observed. Actinomycetes are a large and diverse group of Gram-positive bacteria that have growth habits similar to […]

This test determines the presence of culturable psychrophilic actinomycetes in bulk and swab samples. Results of this test are provided semiquantiatively, as 1+, 2+, 3+, etc., where the numeral preceding the “plus sign” indicates the order of magnitude of colonies recovered in culture. Actinomycetes are a large and diverse group of Gram-positive bacteria that have […]

This test determines the presence of culturable mesophilic actinomycetes in bulk and swab samples. Test results are provided semiquantitatively as 1+, 2+, 3+, etc., where the number preceding the “plus sign” indicates the order of magnitude of colonies observed. Actinomycetes are a large and diverse group of Gram-positive bacteria that have growth habits similar to […]
