Definitions

  • the invention provides a rapid homogeneous immunoassay detection method for microorganisms (e.g., living bacteria).
  • microorganisms e.g., living bacteria.
  • the immunoassay is a simple mix-and-read format that can generate results in ⁇ 20 minutes and can be used for, e.g., food safety testing, water safety testing, and any industry where microbial contamination is a concern (such as hospitals).
  • the immunoassay could be used as a rapid, up-front diagnostic that could later be confirmed by traditional methods; for example, as an initial, quick method to determine if a bacterial infection is Gram-positive or Gram-negative.
  • the sample can be any suitable sample, including one that is suspected of containing microorganisms (e.g., bacteria).
  • the sample can be obtained from any suitable source, including, but not limited to, a patient, a liquid, any kind of food, a drug, or a swab.
  • Typical samples which can be used in the methods of the invention include bodily fluids such as blood, which can be anticoagulated blood as is commonly found in collected blood specimens, plasma, serum, urine, stool, sputum, mucus, semen, saliva, cell cultures, tissue extracts, body swabs, and the like.
  • Other types of samples include solvents, seawater, industrial water samples, food samples, and environmental samples such as soil, water, and plant materials.
  • the microorganisms are bacteria (e.g., living bacteria, spores, etc), such as Gram-positive or Gram-negative bacteria. Any bacteria can be detected including, but not limited to, bacteria of the following genera: Corynebacterium,
  • Staphylococcus e.g., Methicillin-resistant Staphylococcus aureus, i.e., MRSA
  • Streptococcus Clostridia, Neisseria, Campylobacter, Enterobacter, Escherichia, Bacteriodes, Burkholderia, Haemophilus, Klebsiella, Legionella, Proteus, Pseudomonas, Salmonella, Shigella, Vibrio, Yersinia, and/or Mycoplasma.

  • Sbps can be conjugated to one or more molecules of either an activator or a chemiluminescent compound.
  • step (a) chemiluminescent compound
  • enhancers include phenolic compounds and aromatic amines known to enhance other peroxidase reactions as described in U.S. Patent Nos. 5,171,668 and 5,206,149.
