AI Article Synopsis
- Preventing canine Leishmania infantum infections is essential for controlling cases of visceral leishmaniasis in Brazil.
- A proposed bill (PL 1738/11) suggests implementing a national vaccination policy for dogs against this disease.
- However, there is insufficient scientific evidence that such a vaccination would effectively reduce human infection risks, so insecticide-impregnated collars should be prioritized, with vaccines used selectively for individual dog protection.
Article Abstract
Prevention of canine Leishmania infantum infection is critical to management of visceral leishmaniasis in people living in endemic areas of Brazil. A bill (PL 1738/11), currently under consideration, proposes to establish a national vaccination policy against canine leishmaniasis in Brazil. However, there is no solid scientific evidence supporting the idea that this could reduce transmission from infected vaccinated dogs to sand flies to a level that would significantly reduce the risk of L. infantum infection or visceral leishmaniasis in humans. Thus, we advocate that insecticide-impregnated collars should the first line protective measure for public health purposes and that vaccines are applied on a case-by-case, optional basis for individual dog protection.

The analysis of the volatile compounds released by biological samples represents a promising approach for the non-invasive diagnosis of a disease. The present study, focused on a population of dogs infected with canine leishmaniasis, aimed to decipher the volatolomic profile associated with this disease in dogs, which represent the main animal reservoir for Leishmania pathogen transmission to humans. The volatiles emitted by the breath and hair of dogs were analysed employing the gas chromatography-mass spectrometry (GC-MS) technique.

Background: Meglumine antimoniate is used to treat canine leishmaniosis. In humans, it has been associated with pancreatitis. Although a few case reports have described acute pancreatitis secondary to antimonial treatment in dogs, some studies have concluded that pancreatitis is not an adverse effect of this medication.

Programmed cell death plays a relevant role in the pathogenesis of visceral Leishmaniasis. Apoptosis selects suitable parasites, regulating parasite density, whereas autophagy eliminates pathogens. This study aimed to assess the inflammation and apoptosis in inflammatory cells and presents a unique description of the presence of autophagic and apoptotic Leishmania amastigotes in naturally Leishmania-infected dogs.

In Colombia, human leishmaniasis is endemic in rural areas, with increasing reports of outbreaks and cases in urban areas. Cartagena, an urban city in the Colombian Caribbean with a wildland-urban interface, faced its first local cases between 2011 and 2015. Despite reports, visceral leishmaniasis (VL) remains neglected and understudied and almost devoid of active surveillance.
