Leptospirosis is a zoonotic bacteria that can cause great harm to your pet’s health. Due to its zoonotic potential, it’s important to understand this bacteria, and how to best prevent the infection.

What is Leptospirosis?

Leptospirosis is a bacterial spirochete that burrows into the skin with the help of it’s corkscrew shape. Once it has made it’s way into the skin, it spreads through the system by the bloodstream. Once in the body, leptospires will spread throughout the entire body, reproducing in the kidneys, liver, central nervous system, eyes, and reproductive system. Infection of the liver and kidneys can be especially dangerous, as this can lead to organ failure if left untreated.leptospirosis in dogs I Love Veterinary

How can you diagnose Leptospirosis in Dogs?

Definitive testing for Leptospirosis will require a blood and urine sample. These samples can be sent to a local lab for a DNA-PCR test, that tests for the DNA in the Leptospira bacteria. Other diagnostics that often lead up to the need for PCR testing are CBC’s, biochemistries, and urinalysis testing.

How worried should we be about it’s zoonotic potential?

If a dog is a Leptospirosis suspect or being treated for the disease, precautions should be taken. Any dog with Lepto should be handled with gloves, and any contaminated objects should be disposed of immediately. Leptospirosis in humans is usually contracted by being involved in water activities, but this does not mean that it’s impossible to contract the bacteria from a pet. To be safe, it’s best to monitor anyone who has been in contact with the infected dog closely. Better yet, a visit to your primary doctor to discuss potential exposure is recommended.dog in a muddy place I Love Veterinary
