Leptospirosis




What is Leptospirosis?



Leptospirosis is a bacterial disease that can be found in most animals, including livestock (cattle, pigs, and sheep) and wildlife (deer, raccoons, opossums, skunks, rats and other rodents). The bacteria are passed via the urine into water sources, where they reside and reproduce.



Is it a problem where I Live?



Leptospirosis is prevalent in rural, suburban and urbanized areas. The bacteria can be present in any stagnant surface water, moist soil and recreational water sources such as ponds and lakes. Additionally, natural disasters, such as floods and earthquakes present an increased risk of exposure to the disease.



Can my Dog get Leptospirosis?



Your dog can become infected with leptospirosis by drinking, swimming in or walking through contaminated water. Bacteria can enter the bloodstream through a cut in the skin or through mucous membranes (such as eyes, nose, or mouth).



Leptospirosis is a contagious disease and can be transmitted dog to dog. In urban areas, infected dogs can transmit the disease to other-low-risk dogs.



Exposure risk increases during the summer and early fall month, and other periods of high rainfall.



Can Cats Catch this Disease?



Although cats are potentially at risk for leptospirosis, they appear to have natural resistance. For this reason, cats are not vaccinated against leptospirosis.



Can People Catch Leptospirosis?



YES! The U.S. Centers for Disease Control and Prevention estimates that up to 200 human cases of leptospirosis a year are identified in the United States.



While the disease is rarely fatal in humans, it can cause severe illness.



You may reduce disease risk by complying with the following preventive measures:




  1. Vaccinate your dog and livestock.


  2. Avoid water that might be contaminated with the bacteria, especially water that is stagnant.



  3. Practice good sanitation, including washing your hands and your children's hands-especially when handling anything that might have your dog's urine on it.



  4. If your occupation or lifestyle involves routine exposure to wildlife or standing water, wear protective clothing to avoid exposure.


What are the Signs of Leptospirosis?



Look for the following signs that could indicate your dog has been infected with leptospirosis:



Flu-like symptoms are most common, including:





  • Fever



  • loss of appetite



  • Vomiting



  • Diarrhea



  • Dehydration



  • Weakness



  • Depression



  • Lethargy



  • Jaundice, marked by a yellow cast in the gums of the mouth and whites of the eyes.



  • In the most severe cases, the disease can lead to kidney failure or liver failure and may be fatal.


How can I protect My Dog from Leptospirosis?



Remember...Protection = Prevention!!!



To protect your dog from this potentially fatal disease, vaccination is key. By vaccinating your dog before exposure to the disease, you may avoid the emotional and financial trauma of dealing with this disease.



Vaccines are affordable, convenient and safe. Talk to your veterinarian about which vaccine is best and how to incorporate it into your dog's routine vaccination program.



Do Vaccines prevent the most common Canine Leptospira?



The most complete leptospirosis protection is with vaccines containing the four most common strains of leptospira bacteria diagnosed today.



Cornell University recently reported that the vast majority of leptospirosis cases they diagnosed in dogs were caused by two strains.



Vaccination for leptospirosis is routinely administered to dogs in combination with other common canine vaccines.



Your veterinarian will initially recommend a two-shot series. Re vaccination frequency will be based on your dog's risk of exposure.
