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.
Heat 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.
