Considerations. The most common organisms in the normal bacterial flora that inhabits the large intestine are anaerobes (Bacteroides, gram-positive rods, and gram-positive cocci), gram-negative enteric organisms, and Enterococcus faecalis. Using differential selective media and enrichment cultures, normal flora can be differentiated.
Rabbits by nature are cold weather animals. They can easily tolerate temperatures at 32 degrees Fahrenheit or lower providing they have shelter from the wind and wet conditions. They have trouble tolerating temperatures above 85 degrees Fahrenheit and must be kept out of direct sun light during the summer months.
For example, at 104 degrees Fahrenheit, rabbits are much hotter than humans and other mammals are a bit colder. One downside of a higher body temperature is of the amount of food it takes to keep the fire burning. Still, maintaining a warmer body could have provided the critical edge mammals needed to outlast the dinosaurs. The asteroid reset things by killing off dinosaurs and large animals, Casadevall said.
