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.
In this exercise, you will perform an endospore stain on Bacillus spp. a nonpathogenic, spore forming Gram positive rod. The instructor will provide a sample containing bacteria that have been grown under different conditions: bacteria grown for 4-8 hours, vegetative bacteria; bacteria grown for 24-48 hours, vegetative bacteria containing endospores and bacteria grown for 72 hours; mature free endospores.
