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.
However, completely developed adult fleas can live for several months without eating, so long as they do not emerge from their puparia. Optimum temperatures for the flea's life cycle are 21 Â°C to 30 Â°C (70 Â°F to 85 Â°F) and optimum humidity is 70%. Adult female rabbit fleas, Spilopsyllus cuniculi, can detect the changing levels of cortisol and corticosterone hormones in the rabbit's blood that indicate it is getting close to giving birth.
