Leishmaniasis in dogs: what real veterinary cases show
Leishmaniasis in dogs is a disease caused by the Leishmania parasite, which is transmitted through the bite of infected sandflies. It is more common in regions like the Mediterranean, South America, and parts of Asia. This disease can affect various body systems, primarily the immune system, leading to a range of symptoms.
Owners often first notice skin lesions, weight loss, and lethargy in their dogs. Early detection is crucial because the disease can progress to more severe systemic issues, affecting the dog's overall health and quality of life.
What vets typically check for
- Perform a thorough physical examination and review the dog's travel history.
- Conduct blood tests to check for anemia, kidney function, and specific antibodies against Leishmania.
- Take skin biopsies or aspirates from lymph nodes for microscopic examination.
- Use PCR testing to detect Leishmania DNA in blood or tissue samples.
- Initiate treatment with antimonial drugs and allopurinol to manage symptoms and reduce parasite load.

- Scoring clinical signs can help diagnose canine visceral leishmaniasis in a highly endemic area in Brazil
Memorias do Instituto Oswaldo Cruz · BR
A group of 265 dogs in Brazil were tested for canine visceral leishmaniasis (CVL), a serious disease spread by sandflies. The dogs showed various symptoms, including enlarged lymph nodes, skin lesions, and changes in their nails and muzzle color. Researchers developed a scoring system based on these clinical signs to help veterinarians diagnose CVL more effectively, especially

Revista Brasileira de Parasitologia Veterinária · BR
Six dogs in Pedregulho, Brazil, were diagnosed with visceral leishmaniasis, a serious infectious disease spread by sand flies. These dogs showed various symptoms that can be similar to other illnesses, making diagnosis challenging. To confirm the disease, veterinarians used blood tests and a bone marrow test, which is the most reliable method. This case is particularly concerni
- Comparative evaluation of several methods for Canine Visceral Leishmaniasis diagnosis
Revista Brasileira de Parasitologia Veterinária · BR
A group of dogs suspected of having Canine Visceral Leishmaniasis (CVL) underwent various tests to diagnose the disease. The tests included blood tests that looked for antibodies against the Leishmania parasite, with the ELISA test using soluble extract (ELISA-SE) being the most effective, identifying 71.6% of the dogs. The study found that using multiple tests together is nece
- Leishmania (infantum) chagasi in canine urinary sediment
Revista Brasileira de Parasitologia Veterinária · BR
A group of 70 dogs from a veterinary hospital in Brazil was tested for a serious disease called canine visceral leishmaniasis (CVL), which is caused by a parasite. Many dogs showed no symptoms, making it hard to diagnose. The researchers found that 61% of the dogs had the parasite in their bone marrow or lymph nodes, and about 9% had it in their urine. Blood tests also showed a

Pesquisa Veterinária Brasileira · BR
Fifteen dogs in Brazil were diagnosed with sporotrichosis, a rare fungal infection that caused painful, ulcerated skin lesions, primarily on their heads and legs. Some dogs showed more severe symptoms, including respiratory issues like sneezing and nasal discharge, along with weight loss and skin necrosis. Diagnosis was confirmed through tests that examined skin samples. Treatm
