Leptospira bacteria can survive and thrive for up to 180 days given the right conditions; namely, warm, damp environments and stagnant water. Annual vaccination can prevent leptospirosis caused by serovars included in the vaccine and is recommended for dogs at risk of infection. Stages With Scary Consequences. Finally, some infected dogs may not show any symptoms, while still shedding leptospires! Leptospirosis is spread by infected dogs, mice, rats and cows but can also be caught from infected water. When titers to a particular serovar reach high levels, e.g., 1:3200 to 1:6400, it is not unusual to see elevated titers to other serovars, which is likely due to cross reactions. Dog social behavior traits for a perfect companion, Old dog vestibular disease recurrence: odds are low, dog is already under antibiotic treatment, dog is suspected, owners (and nursing staff) should therefore take precautions when handling the animal, and particularly its urine, by wearing gloves, washing their hands after any handling and disinfection of areas where the dog has hung around, Can Periodontal Disease Kill My Dog?

The results of all diagnostic tests should be interpreted in light of the animal's vaccination history, clinical signs, and clinicopathologic findings. It appears to be infrequently associated with experimental canine leptospirosis; however, rare case reports exist. Previously vaccinated older dogs who, later, become naturally infected with a field strain homologous to a vaccine serovar generally have minimal clinical signs. Leptospirosis essentially results in kidney damage (sharp increase in urea and creatinine leading to depression, vomiting, etc. The trusted provider of veterinary information since 1955, Last review/revision Feb 2022 | Modified Oct 2022.

Leptospires which have localized in the kidney tubules (Fig. The kidneys (and the liver to a lesser extent), are often seriously affected, sometimes irreversibly destroyed. Renal replacement therapy with intermittent hemodialysis or continuous renal replacement therapy should be considered for dogs that are anuric or oliguric despite appropriate supportive therapy. 1). Humans are also vulnerable to leptospirosis. Conjunctivitis. Of all the diseases we do dialysis for, leptospirosis has one of the best outcomes, said Foster. Three more dogs passed away due to kidney or liver damage in the months following their release. Leptospirosis should also be considered in any dog with previously diagnosed chronic kidney disease that develops acute-on-chronic kidney injury. Urine shedding may last for prolonged periods, but antibody levels eventually decline since the leptospires, protected in the renal tubules, do not stimulate antibody production. Despite the availability of vaccines for several decades, the duration of vaccine induced immunity is not known since data from long-term challenge studies are not available. J Am Vet Med Assoc 2000; 216:371-375. Yes, dogs can survive leptospirosis. Dogs can get leptospirosis from puddles or bodies of water that carry urine from infected wildlife.

The liver is often friable with an accentuated lobular pattern and might have a yellowish-brown discoloration. J Feline Med Surg. In the most serious cases, the dog no longer emits urine at all (anuria during acute renal failure), but in less severe cases, on the contrary, we may observe increased thirst and more frequent urination. Normal kidney (left), diseased kidney (right). The bacteria (Leptospira) that cause leptospirosis, commonly called leptospires, thrive in water. Also, dogs in fenced yards may be exposed to urine from wildlife, including rodents; dogs which are exercised by walks in parks and those who roam in the countryside or swim in ponds and slow running streams are at greatest risk to exposure to leptospires. Dogs may vomit (Fig. The treatment of the disease, as a whole, is much more complicated. Combination of the following findings: acute azotemia, cholestatic liver disease, mild to moderate thrombocytopenia, and glucosuria with normal blood glucose, Serologic testing to detect antibodies, combined with PCR assay to detect organisms. 5) and/or have diarrhea resulting in rapid dehydration and excessive thirst. Dogs affected by leptospirosis might show clinical signs that include lethargy, anorexia, vomiting, abdominal pain, and polyuria, oliguria, or anuria. The localization of leptospires in the proximal tubules of the kidney, and survival in cerebrospinal fluid (CSF) and vitreous humor of the eye in some infected animals, reflects the inability of antibodies to penetrate into those sites without causing inflammation.

Because many aspects of the infection are poorly understood, there is the possibility that the disease in dogs may go undiagnosed. There are 17 species of these bacteria, (and more than 230 serovars), more or less dangerous, and more or less specific to a species of mammal. Responses to infection in previously vaccinated dogs generally result in anamnestic responses only to the homologus serovars. Sykes JE, Hartmann K, Lunn KF, Moore GE, Stoddard RA, Goldstein RE. Infection of dogs with the host adapted, commonly results in chronic interstitial nephritis (, .

Because of increased building and development into areas that were previously rural, pets may be exposed to more wildlife, such as raccoons, skunks, squirrels, opossums, or deer that are infected with leptospirosis. Current vaccine research is concerned with subunit products and is aimed at determining which fraction(s) of the leptospiral cell wall are immunogenic and protective without being toxic to the animal. However, this is a challenge as there are a lot of types of leptospires, so volume of tests required is massive. Please contact your veterinary medical service provider if you have questions regarding this or any other veterinary medical issue. Leptospirosis occurs worldwide; however, it is not uncommon to find endemic disease in a particular geographic region caused by infections with only one, or several, serovars.
