This protocol describes the rapid non-enzymatic dissociation of fresh human tissue fragments for qualitative and quantitative assessment of CD45+ cells (lymphocytes/leukocytes) present in various normal and malignant human tissues. Additionally, the supernatant obtained from the primary tissue homogenate can be collected and stored for further analysis or experimentation.
FAQs
Defined antimicrobial concentrations provide controlled conditions for observing whether a bacterial isolate continues growing or shows inhibition. The resulting response supports classification as susceptible or resistant to the selected antibiotics. Because the concentrations and readouts are standardized, the protocol can produce interpretable evidence for treatment decisions rather than relying only on general assumptions about the organism.
Phenotypic readouts assess the organism’s observable growth or inhibition after antimicrobial exposure, while instrument-based readouts use an analytical system to detect that response. Both approaches connect antimicrobial exposure with a susceptibility result. Their value is speed: they can shorten the interval between bacterial isolation and actionable susceptibility information when used within a standardized workflow.
Quality controls help establish that the testing workflow and its readouts are performing appropriately before results guide clinical interpretation. Without appropriate controls, an apparent susceptibility or resistance result may be harder to assess confidently. Including these controls strengthens the reliability of results used for therapy selection, antimicrobial stewardship, infection control, and resistance research.
The protocol accelerates the path from bacterial isolation to a susceptibility result by streamlining antimicrobial exposure and the measurement of growth or inhibition. Its workflow still retains defined test conditions, standardized readouts, and appropriate quality controls. This combination reduces delay while preserving the information needed to distinguish effective from ineffective selected antibiotics.
Results can help clinicians select an antibiotic to which the bacterial isolate is reported susceptible, rather than continuing unnecessary empiric reliance on broader therapy. This is especially relevant when timely treatment decisions matter for serious bacterial infections. The result should be interpreted alongside appropriate quality controls and the clinical context rather than viewed in isolation.
By providing susceptibility information sooner, rapid AST can support more targeted antibiotic decisions and reduce unnecessary use of broad-spectrum agents. The approach therefore connects laboratory testing with stewardship: clinicians receive evidence about the isolate’s response to selected drugs and can use that information when refining therapy, while still considering the complete clinical situation.
Rapid AST also contributes to infection-control decisions and research on emerging antimicrobial resistance. Susceptibility patterns can provide useful information for recognizing resistance concerns and supporting responses within medical settings. In research, the protocol offers a structured way to examine isolate responses to selected antibiotics, provided that results are interpreted with appropriate quality controls.
