Despite the success of widespread vaccination campaigns, outbreaks are still reported globally, particularly in densely populated environments such as kennels, shelters, and breeding centers. For veterinary epidemiologists, one of the biggest challenges …
Optimization of Carbol Fuchsin Kinyoun Staining for Environmental and Clinical Microbiology Samples
When (and when not) to use Kinyoun Use Kinyoun when heating is impractical (field work, busy benches), phenolic primary stain is available, and you need rapid same-day reads. The method relies on high phenol/basic fuchsin to drive dye across the mycolate-rich wall without heating. assets.thermofisher.com Know its ceiling. Fluorochrome stains …
