OBJECTIVES Establishing indirect immunofluorescence (IFAT) and enzyme-inked immunoassay (ELISA) serological tests' ability to detect canine visceral leishmaniasis (CVL) infection. METHODS 211 cross-bred dogs from the south of the Tolima department (a visceral leishmaniasis endemic area) were evaluated by clinical and serological exams, using the Colombian Leishmania infantum (infantum) MHOM/C...

An autochthonous case of visceral leishmaniasis is reported in a dog (Canis familiaris) as an apparently natural infection in a non-endemic area. DNA obtained from spleen and liver samples produced the expected fragment in a Leishmania-specific rDNA-based nested-PCR assay. The PCR product, a 490 bp fragment, was sequenced and the nucleotide sequence was identical to that of Leishmania (Leishman...

The southern habitats of Croatia's gray wolf (Canis lupus) population are found in central and southern parts of Dalmatia. This region is recognized as an endemic region for canine visceral leishmaniosis, caused by Leishmania infantum. In November 2003, a 4-yr-old male gray wolf was found dead in the northwestern border of this endemic region. Pathologic and parasitologic analysis, confirmed by...

Canine visceral leishmaniasis (CVL) is endemic in numerous Brazilian regions. The greatest difficulty in controlling the disease is the diagnostic limitation. In the present study, the most common tests employed for visceral leishmaniasis diagnosis were compared: immunofluorescence antibody test (IFAT), immunoenzymatic assay (ELISA), direct parasitological examination and polymerase chain react...

Visceral fat has long been associated with the development of insulin resistance. Although the mechanism is not well understood, it has been suggested that an increase in this fat depot results in an elevation in portal vein levels of free fatty acids and/or adipokines, adversely affecting hepatic glucose production. Overactivity of the endocannabinoid system is closely related to abdominal obe...

Visceral leishmaniasis (VL) is an important zoonosis caused by Leishmania infantum, which has in the domestic dog its principal vertebrate host in urban environments. VL is usually transmitted by phlebotomine sand flies, however atypical routes of transmission have been described. In this review we discuss the role of sexual and vertical transmissions, and their implications in the maintenance ...

Leishmaniasis is a zoonotic disease caused by predominantly vectorborne Leishmania spp. In the United States, canine visceral leishmaniasis is common among hounds, and L. infantum vertical transmission among hounds has been confirmed. We found that L. infantum from hounds remains infective in sandflies, underscoring the risk for human exposure by vectorborne transmission.
