[leishmaniasis in domestic dogs: epidemiological aspects].in barra de guaratiba, an endemic area for american visceral leishmaniasis (avl) in rio de janeiro, brazil, control campaigns were unable to reduce canine infection rates. this difficulty prompted an in-depth study of dogs as a reservoir for leishmania chagasi in the peri-urban environment through clinical and serological follow-up using the immunofluorescence and western blot techniques. recognition of 29 kda and 32 kda peptides by sera from dogs with proven l. chagasi infection was observed. f ...200515692667
identification of leishmania (leishmania) chagasi isolated from healthy skin of symptomatic and asymptomatic dogs seropositive for leishmaniasis in the municipality of rio de janeiro, brazil.euthanasia of seropositive dogs has been one of the principal measures adopted by the program for the control of leishmaniasis in brazil for many years. however, its efficacy is currently being questioned. we obtained intact skin samples from 20 leishmania-reactive dogs from the municipality of rio de janeiro that had been referred for euthanasia. the promastigote forms of leishmania were isolated in culture from 18 of these animals. fourteen of these isolates were identified as leishmania (leis ...200415880235
first report of natural infection of a bush dog (speothos venaticus) with leishmania (leishmania) chagasi in brazil.we report here the first known case of natural infection of a bush dog with leishmania (leishmania) chagasi in brazil. the specimen was captured in the wild in the state of mato grosso and is currently being held in captivity at fundação jardim zoológico, rio de janeiro, brazil. the leishmaniasis was diagnosed by culture of promastigote forms in intact skin fragments and their characterization by isoenzyme electrophoresis. this report calls attention to the parasitological and etiological contro ...200818036627
[canine visceral leishmaniasis in maricá, state of rio de janeiro: first report of an autochthonous case].visceral leishmaniasis is a zoonosis of public health importance, and dogs represent one of the main problems. this paper describes the first autochthonous case of canine visceral leishmaniasis in the municipality of maricá. it provides new facts regarding the geographical distribution of leishmania (leishmania) chagasi in the state of rio de janeiro.200919287941
[report on an autochthonous case of canine visceral leishmaniasis in the southern zone of the municipality of rio de janeiro].brazil is facing expansion and urbanization of american visceral leishmaniasis, with human and canine cases in several large-sized cities. this report describes an autochthonous case of canine visceral leishmaniasis in a nonendemic area in the municipality of rio de janeiro.201020305979
first report of cutaneous leishmaniasis caused by leishmania (leishmania) infantum chagasi in an urban area of rio de janeiro, brazil.american tegumentary leishmaniasis (atl) is an infectious disease caused by protozoa of the genus leishmania, and transmitted by sandflies. in the state of rio de janeiro, almost all of the cases of american tegumentary leishmaniasis (atl) are caused by leishmania (viannia) braziliensis, while cases of visceral leishmaniasis (vl) are caused by leishmania (leishmania) infantum chagasi. the resurgence of autochthonous vl cases in rio de janeiro is related to the geographic expansion of the vector ...026603237
geographical expansion of canine visceral leishmaniasis in rio de janeiro state, brazil.visceral leishmaniasis (vl) is a vector-borne disease that affects humans, and domestic and wild animals. it is caused by the protozoan leishmania (leishmania) infantum (syn = leishmania chagasi). the domestic dog (canis familiaris) is considered the main reservoir of the etiologic agent of vl in domestic and peridomestic environments. in the past three years, although control actions involving domestic dogs are routinely performed in endemic areas of the rio de janeiro state, new cases of canin ...026603233
natural infection of didelphis aurita (mammalia: marsupialia) with leishmania infantum in brazil.the opossum didelphis have been considered as natural hosts of leishmania parasites in the new world, suggesting an important role in the epidemiology of visceral leishmaniasis (vl). among six extant species that belong to the genus didelphis, only two (d. marsupialis and d. albiventris), have been mentioned as natural hosts of leishmania infantum in brazil and colombia. in the present paper, it is reported for the first time, the observation of intracellular parasites (amastigotes) in tissues o ...201222676324
first case of autochthonous human visceral leishmaniasis in the urban center of rio de janeiro: case report.visceral leishmaniasis is an anthropozoonosis that is caused by protozoa of the genus leishmania, especially leishmania (leishmania) infantum, and is transmitted to humans by the bite of sandflies of the genus lutzomyia, such as lutzomyia longipalpis. there are many reservoirs, including canis familiaris. it is a chronic infectious disease with systemic involvement that is characterized by three phases: the initial period, the state period and the final period. the main symptoms are fever, malnu ...024553614
identification of canine visceral leishmaniasis in a previously unaffected area by conventional diagnostic techniques and cell-block fixation.after the report of a second case of canine visceral leishmaniasis (cvl) in são bento da lagoa, itaipuaçu, in the municipality of maricá, rio de janeiro state, an epidemiological survey was carried out, through active search, totaling 145 dogs. indirect immunofluorescence assay (ifa), enzyme-linked immunosorbent assay (elisa), and rapid chromatographic immunoassay based on dual-path platform (dpp) were used to perform the serological examinations. the parasitological diagnosis of cutaneous fragm ...201626910449
canine cutaneous leishmaniasis caused by neotropical leishmania infantum despite of systemic disease: a case report.visceral leishmaniasis is an anthropozoonosis caused by a protozoan leishmania infantum (syn. leishmania chagasi). here, we report a typical case of canine cutaneous leishmaniasis due to l. infantum infection without any other systemic symptom in one dog in the city of rio de janeiro, brazil. a mongrel female dog was admitted in a veterinary clinic with reports of chronic wounds in the body. physical examination revealed erosive lesions in the limbs, nasal ulcers, presence of ectoparasites and s ...201222583758
