Leptospirosis: Bacterial Infection in Dogs

Leptospirosis: Bacterial Infection (Spirochetes) in Dogs

Leptospirosis is an infection of bacterial spirochetes, which dogs acquire when subspecies of the Leptospira interrogans penetrate the skin and spread through the body by way of the blood stream. Two of the most typically seen members of this subspecies are the L. grippotyphosa and L. Pomona bacteria. Spirochetes are spiral, or corkscrew-shaped bacteria which penetrate the system by burrowing into the skin.

Bacterial spirochetes spread throughout the entire body, reproducing in the liver, kidneys, main nervous system, eyes, and reproductive system. Soon after preliminary infection, fever and bacterial infection of the blood develop, but these symptoms quickly solve with the reactive boost of antibodies, which clear the spirochetes from most of the system. The extent to which this bacteria impacts the organs will depend on your dog’s body immune system and its ability to eradicate the infection completely. Even then, Leptospira spirochetes can stay in the kidneys, recreating there and contaminating the urine. Infection of the liver or kidneys can be fatal for animals if the infection progresses, causing severe damage to these organs. Younger animals with less industrialized immune systems are at the greatest risk for severe complications.

The Leptospira spirochete bacteria is zoonotic, implying that it can be sent to humans and other animals. Children are most at risk of obtaining the bacteria from an infected pet.

Symptoms and Types of Bacterial Spirochetes in Dogs

Causes Bacterial Spirochetes in Dogs

The Leptospira spirochete infection generally occurs in subtropical, tropical, and damp environments. Leptospira spirochetes are more prevalent in marshy/muddy areas which have stagnant surface water and are frequented by wildlife. Heavily irrigated pastures are likewise typical sources of infection. The infection rate for domestic pets has been increasing in the U.S. And Canada, with infections happening most frequently in the fall season. Dogs will normally enter into contact with the leptospira bacteria in infected water, soil, or mud, while swimming, going through, or drinking contaminated water, or from entering contact with urine from an infected animal. This last approach of contact might take place in the wild. Hunting and sporting dogs, dogs that live near wooded areas, and dogs that live on or near farms are at an increased risk of acuiring this bacteria.

Your veterinarian will buy a chemical blood profile, a complete blood count, a urinalysis, an electrolyte panel, and a fluorescent antibody urine test. Urine and blood cultures will also be ordered for analyzing the occurrence of the bacteria. A tiny agglutination test, or titer test, will also be performed to determine the body’s immune reaction to the infection, by determining the presence of antibodies in the bloodstream. This will assist to definitively determine leptospira spirochetes and the level of systemic infection.

Gloves need to be used during the cleaning process and disposed of correctly after.

Finally, if you do have other pets or children in the home, they may have been infected with the leptospira bacteria and are not yet revealing symptoms. It might be beneficial to have them (and yourself) tested for the existence of the bacteria.
