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.

1 Apply stain while keeping the slide and perhaps some paper on top of the slide wet for 10 minutes (add more stain to keep it wet). 2  If using Steam: 3  Place the slide(s) on a slide holder over steaming water. 4  Optional, you may cover the slide with a piece of bibulous paper or other paper cut to fit the slide.eat or steam is used to get Malachite Green into the endospores (and the vegetative cells as well. All but one species that produce endospores have vegetative bacilli.) The slide is them washed with water. As Malachite Green is a water soluble stain, it washes out of vegetative cells, but not out of the endospores.
