“…Reported estimates of ACL prevalence in dog populations (Table 2) must be treated with caution because many are based on non-random (e.g., clinically positive) sampling of dog populations, 59,74,78,88,91,93,150,151 which are mainly designed to provide parasite isolates for species identification and characterization. 60,62,[63][64][65][66][67]71,79,83,86,87,98 The biting rate of sandfly vectors on dogs.…”

Abstract. Originally associated with forested areas, the transmission cycle of American cutaneous leishmaniasis (ACL) has now adapted to the domestic environment in at least 9 Latin American countries. Several studies have suggested that the domestic dog (Canis familiaris), which is already incriminated as the primary reservoir host of zoonotic visceral leishmaniasis (ZVL), may have a reservoir role in the domestic transmission of human ACL caused by Leishmania braziliensis, L. panamensis, and L. peruviana. This article reviews more than 90 studies reporting ACL infections in dogs, and concludes that as yet there is only circumstantial evidence to support that claim. Almost no data are available on the infectiousness of dogs to sandfly vectors of ACL, and there are few indications that either dog ownership or dog abundance are risk factors for ACL. Nevertheless, it has been proposed that incidence of ACL in humans could be reduced by targeting infected dogs. While this control strategy has been used for many decades against ZVL in Latin America, Europe, and Asia, there is little evidence to demonstrate its effectiveness either in theory or in practice. Particular concerns over the sensitivity and specificity of diagnostic tools, low compliance rates among dog owners, and cost-effectiveness are likely to apply equally to ACL control.The leishmaniases are a group of zoonotic diseases transmitted to humans and animals by the bite of phlebotomine sand flies (Diptera: Psychodidae). Despite their multiple etiologies, the New World leishmaniases can be divided into two broad categories: zoonotic visceral leishmaniasis (ZVL) and American cutaneous leishmaniasis (ACL).1 The latter includes localized cutaneous, mucocutaneous, and diffuse cutaneous leishmaniasis. Whereas ZVL is almost exclusively caused by Leishmania chagasi (L. infantum), ACL is caused by several Leishmania species, of which L. braziliensis is the most widespread. Many sandfly species have been incriminated as vectors of ACL throughout its geographic range, but reservoir hosts have only been identified for L. amazonensis, L. mexicana, L. guyanensis, and L. panamensis, and are unknown or unproven for both L. braziliensis and L. peruviana. 1 Originally associated with forested areas, 2 the transmission cycle of ACL has now adapted to the domestic environment due to deforestation and urbanization. 3,4 The transition from sylvatic to domestic transmission cycle was further encouraged by the lack of a specific leishmaniasis control strategy, and the discontinuation of intervention campaigns designed for other infectious diseases, e.g., malaria. 5,6

“…However, they can also fly into homes, establishing contact with people or contaminating their food, a possibility currently increasing as a result of extensive deforestation, loss of wild vertebrate populations, and immigration into previously forested areas. In addition, vampire bats can spread the parasite as they feed, and the predation of infected mammals may provide another means of infection (Maywald et al 1996). Dogs are exposed to infection from biting insects and bats at night, by ingesting the vectors (especially when puppies; Pineda et al 2011)-which is a highly efficient transmission route-and via hunting infected small mammals such as rodents and marsupials (Herrera et al 2011).…”

The canine visceral leishmaniasis (CVL) and american trypanosomiasis are important zoonoses in public health and dogs are the main domestic reservoir of the parasite for humans. The goal of this study was to estimate the prevalence of circulating antibodies anti-Trypanosoma cruzi and anti-Leishmania sp. in sera of dogs from the rural area of Botucatu, SP, Brazil. During the annual vaccination campaign against canine rabies in rural area, 689 blood samples were taken and processed by indirect immunofluorescent antibody test. The serological tests revealed the absence of antibodies anti-Leishmania spp., but anti-T. cruzi antibodies were detected in 3 (0.4%) dogs.
