Antibiotics to be used for Rabbits

Antibiotics are used to treat bacterial infections. When needed for treatment of an infection in arabbit, these drugs should be prescribed only by a veterinarian well-versed in rabbit medicine.Infections caused by bacteria can occur anywhere in the body. The best way to determine which

type of antibiotic will be most effective against a particular infection is to take a sample of infectedtissue (for example, a small section of the wall of an abscess, or a surface swab of the affected area),and send it to a laboratory for culture and sensitivity testing. It is advisable to have both an aerobicand an anaerobic bacterial tests performed to best determine what medications will be most

effective.

In some cases, the infection may occur in an difficult-to-access place, such as inside the respiratorytract, urinary tract, inside of the eye, intestinal tract or bone. In this case, the veterinarian may need

to make a "best guess" about which antibiotic is best to treat the problem.

A review of rabbit physiology helps us to understand why antibiotic use in rabbits is associated withrisk. Rabbits have an unusual digestive system, inhabited by a variety of essential microorganismsthat work together to digest food. The balance (i.e., relative population numbers) of microorganismsin the digestive system is influenced by many factors, including diet and, sometimes, medications.

Some antibiotics can adversely affect the intestinal flora, killing beneficial bacterial and allowingresident pathogenic bacteria, once held in check by competition from the normal intestinal

inhabitants, to overgrow. If the pathogenic bacteria are of certain strains, they will produce toxinsthat can kill the rabbit. This two-step process can take as long as 10 days after treatment has endedto manifest its deadly conclusion, which can obscure the original cause of the problem to

veterinarians not familiar with rabbits. Your bunny may act normal up to one to two days before adisaster strikes, at which point he or she will develop reduced activity, loss of appetite, waterydiarrhea, rapid dehydration, and ultimately can die. Profuse, watery diarrhea (where there are NO

normal or even slightly formed stools) in a rabbit is an extreme emergency (link to Medical FAQs ondiarrhea) and death can occur in 24 to 48 hours after it first appears.

The choice of antibiotic and route of administration are important factors your veterinarianconsiders when treating your rabbit. Table 1 contains a summary of some commonly availableantibiotics, routes of administration, and the risk of antibiotic-associated diarrhea due to disruptionof the normal intestinal flora. These data were compiled from studies performed or veterinary

experience gained with rabbits
