The plates containing the sample and growth medium are incubated (e.g., 32°C,-40° C) for 24 hr to 5 days, depending upon the assay. After incubation, colonies of microorganisms that have grown in the agar are counted. While optical methods have been successfully used to classify microorganisms in clinical samples, the solid substances of the test samples disposed in an aqueous media usually cause optical interference for a detection system. The present invention therefore employs fluorescing indicator substances to enhance the measurement sensitivity of the group of detected microorganisms.
Controlling biological fluids for wound healing and more
US Patent 8535709
Publication date: Sept. 17, 2013
Assignee: Southeastern Medical Technologies, LLC
Disclosed here are therapeutic formulations adapted for positive-pressure application to control biological fluids at a desired site. The disclosed formulations comprise from 25% to 99% w/w liquid-crystal forming compound, and 0% to 75% w/w solvent. In addition, applications described include controlling blood loss, promoting wound healing, providing barriers to seal tissues and prevent adhesions, promoting tissue growth, mimicking soft tissues, and inhibiting microbial infections. Furthermore, it has been discovered that certain fatty acids, when added to these formulations, increase the viscosity or firmness of the highly viscous liquid crystal phase, once formed. The described formulations provide excellent toxicity, sensitization and irritation profiles and may be designed to be biodegradable.
