I recently received the following question on cat health from a visitor to my website: My cat has a slight watery discharge from her right eye and it sometimes âcatchesâ dirt as it slides down her nose. I was just wondering if she has an upper respiratory infection and if so, what can I do â¦
The endospore stain is a differential stain used to visualize bacterial endospores. Endospores are formed by a few genera of bacteria, such as Bacillus.By forming spores, bacteria can survive in hostile conditions. Spores are resistant to heat, dessication, chemicals, and radiation.he endospore stain is a differential stain used to visualize bacterial endospores. Endospores are formed by a few genera of bacteria, such as Bacillus.
Endospore staining is a technique used in bacteriology to identify the presence of endospores in a bacterial sample, which can be useful for classifying bacteria. good stain to use for spore staining is malachite green. It takes a long time for the spores to stain due to their density, so time acts as the mordant when doing this differential stain; the slide with the bacterium should be soaked in malachite green for at least 30 minutes.
