Diagnosis of canine visceral leishmaniasis: Biotechnological advances

Veterinary Journal, 2008
Human visceral leishmaniasis (HVL) is endemic in the tropical and sub-tropical regions of Africa, Asia, the Mediterranean, Southern Europe and South and Central America, with approximately 500,000 new cases reported annually. As dogs are considered to be the major reservoirs for HVL, the accurate diagnosis of disease in these animals is important ...

Assessment of serological tests for the diagnosis of canine visceral leishmaniasis

Veterinary Journal, 2013
An immunoenzymatic assay (ELISA), an indirect immunofluorescence antibody test (IFAT) with different antigens (ELISA-Leishmania chagasi, ELISA-L. major-like, IFAT-L. chagasi and IFAT-L. major-like), and an immunochromatographic test were assessed for the diagnosis of canine visceral leishmaniasis (CVL).

An experimental model for canine visceral leishmaniasis

Parasite Immunology, 1991
Summary Seven mixed‐breed dogs were challenged with either promastigotes or amastigotes of Leishmania donovani infantum strains recently isolated from naturally infected dogs. Different routes and numbers of parasites were utilized and each dog was monitored for at least 1 year post‐infection.

Venereal transmission of canine visceral leishmaniasis

Veterinary Parasitology, 2009
Leishmania chagasi, the agent of visceral leishmaniasis in dogs in the Americas has a tropism to the male genital system, particularly the epididymis, prepuce, and glans penis, resulting in shedding of Leishmania in the semen. The goal of this study was to verify the possibility of venereal transmission of L. chagasi.

Cytokine profiles in canine visceral leishmaniasis

Veterinary Immunology and Immunopathology, 2009
Cytokines play a decisive role in the regulation of the immune response directed against Leishmania infantum, determining the prevention or progression of the infection. This review focuses on advances in the canine immune response knowledge over the recent years and examines the principal role of the cytokine pattern elicited after infection with L ...

Canine visceral leishmaniasis biomarkers and their employment in vaccines

Veterinary Parasitology, 2019
The natural history of canine visceral leishmaniasis (CVL) has been well described, particularly with respect to the parasite load in different tissues and immunopathological changes according to the progression of clinical forms. The biomarkers evaluated in these studies provide support for the improvement of the tools used in developing vaccines ...

Canine visceral leishmaniasis at Wadi Hamam, in Israel

Transactions of the Royal Society of Tropical Medicine and Hygiene, 1988
A preliminary survey of canine leishmaniasis was made in Israel by serodiagnosis, using a direct and competitive enzyme-linked immunosorbent assay. Three (4%) of the 75 dogs surveyed were seropositive. The infected dogs came from Wadi Hamam near Tiberias in northern Israel.

Canine visceral leishmaniasis in villages West of Lanchow, China

Transactions of the Royal Society of Tropical Medicine and Hygiene, 1947
Abstract Forty-four dogs naturally infected with visceral leishmaniasis were found among 1,430 examined in villages about 50 km. west of Lanchow. Epilation and seborrhoea were present in all but one of the dogs. Leishmania were found by skin biopsy in thirty-eight of the forty-four dogs and by ilium puncture in thirty-nine of forty-one dogs in which ...

Canine visceral leishmaniasis: a histopathological study of lymph nodes

Acta Tropica, 2004
Canine visceral leishmaniasis (CVL) is a zoonosis and a chronic systemic disease of the dog caused by a protozoan of the genus Leishmania. In the New World, the disease is caused by the species Leishmania (Leishmania) chagasi. There are only a few studies on the histopathology of lymph nodes in canine leishmaniasis.
