Canine cutaneous leishmaniasis by Leishmania (Viannia) braziliensis in an agricultural settlement, endemic area for leishmaniasis

Abstract

Cutaneous leishmaniasis has several species of Leishmania as agents, and a wide variety of wild and domestic animals as hosts and different species of phlebotomines as vectors. A case of cutaneous leishmaniasis in a dog coming from an agricultural settlement is described. This is the first report of parasitism in a dog by Le. (Viannia) braziliensis in Mato Grosso do Sul State. Attention is called to the importance of including this protozoonosis in the differential diagnosis of dermopathies in dogs as also the need to assess the importance of the domestic dog as a possible reservoir of Le. braziliensis.Keywords: domestic dog, human cases, reservoir RESUMO As leishmanioses tegumentares são antropozoonoses metaxênicas de importância em saúde pública.

Leishmania (Viannia) braziliensis type 2 as probable etiological agent of canine cutaneous leishmaniasis in Brazilian Amazon

“…Apart from this, one also observed that in the study area, the animals live close to the forest, with the presence of reservoirs, in addition to, proven and suspected Leishmania vectors. Thus, these populations, both human and canine, are exposed to two cycles of transmission of Leishmania , a sylvatic one due to predatory activities, and a peridomestic one, because the residences are close to forest environments and frequented by vectors from the sylvatic cycle, making it possible for these dogs to acquire leishmaniosis, these transmission profiles in dogs have also been reported in other regions of Brazil [35, 40, 41].…”

“…High rates of infection in dogs by Leishmania , generally attributed to L . braziliensis , in areas where human ACL occurs, have been reported in several parts of Brazil [6–8, 35] and also in other Latin American countries [36, 37]. However, some discussion has begun with the major emphasis on elucidating the role of the dog as a possible reservoir of this etiological agent [3, 38, 39].…”

Leishmania V. braziliensis infection in asymptomatic domestic animals within an endemic region in the Northeast of Brazil

“…Brazil is one of the top five countries with the highest incidence of ACL worldwide 3,4 . ACL displays specific transmission patterns in Brazil, due to the variety of vectors and reservoir hosts 5,6 . Domestic and wild animals such as canines (Canis familiaris), felines (Felis catus), horses (Equus caballus), donkeys (Equus asinus), and rodents (Necromys lasirus, Nectomys squamipes, Rattus rattus) are considered the main reservoir hosts of the disease 7,8 .…”

Epidemiologia da leishmaniose tegumentar americana (LTA) no município de Xapuri, Estado do Acre, Brasil: estudo em população humana, cães domésticos e vetores

“…Com relação aos reservatórios, este parasito já foi isolado de diferentes animais, tais como roedores e marsupiais, sugerindo estes como possíveis reservatórios primários (ARIAS et al, 1981;DE LIMA et al 2002;BRANDÃO-FILHO et al, 2003). Alguns animais domésticos como cães têm sido encontrados parasitados com L. (V.) braziliensis (MADEIRA et al, 2005;CASTRO et al, 2007;BRILHANTE et al, 2016), porém, ainda não está esclarecido o papel destes animais no ciclo de transmissão desse parasito, se são hospedeiros acidentais ou reservatórios secundários. Alguns estudos indicam que cães infectados por L.…”
