Abstract: a survey for canine tegumentary leishmaniasis (ctl) has been carried out between 1986 and 1993 in seven endemic localities for american cutaneous leishmaniasis in the state of rio de janeiro. 270 dogs have been examined for their clinical aspects, the development of delayed hypersensitivity (dhs) with immunoleish antigen and with immunofluorescent antibody research of igg (if). 28.2% of them had ulcer lesions and 3.3% had scars. the lesions consisted of single (39.5%) and mucocutaneous lesions (31.6%), multiple cutaneous (25.0%) and mucocutaneous lesions associated with cutaneous ulcers (4.0%). twelve (15.8%) isolates from biopsies were analyzed by zimodeme and schizodeme and identified as l. (v.) braziliensis. the overall prevalence of canine infection that was evaluated with the skin test was of 40.5% and with if it was of 25.5%. both tests showed a high positive rate with relation to the animals with mucosal lesions, as in the case of human mucocutaneous leishmaniasis. the comparison of the two tests showed the skin test to have a better performance although there was no statistical difference (p>0.05) between them. the proportional sensitivity and specificity was of 84.0% and 74.0%, respectively. the immunoleish skin test and if are useful tools to be employed in ctl field epidemiological surveys.

Oliveira Neto, M. P.;Grimaldi Junior, Gabriel;Momen, Hooman;Pacheco, R. S.;Marzochi, Mauro Celio de A.;McMahon Pratt, D.;
Memórias do Instituto Oswaldo Cruz , 1986, DOI: 10.1590/S0074-02761986000300006
Abstract: l.d. chagasi was isolated from active cutaneous leishmaniasis in both human and canine infections in an endemic area in rio de janeiro, brazil. both isolates were identified by molecular and immunological characterization of the parasite using three different methods: electrophoretic mobility of isoenzymes; restriction endonuclease fragment analysis of kdna and serodeme analysis using monoclonal antibodies. this seems to be the first well documented case in the new world of a "viscerotropic" leishmania inducing a case of cutaneous leishmaniasis. this observation emphasizes that the diagnosis of the etiologic agent of human or canine visceral leishmaniasis based solely upon clinical and epidemiological critwria may lead to erroneous conclusions.

Abstract: introduction: american tegumentary leishmaniasis (atl), including mucocutaneous leishmaniasis (mcl) and localized cutaneous leishmaniasis (lcl), is endemic in bolivia. we describe the results of active surveillance of atl from 2001 to 2006 and assess demographic data related to atl epidemiology in the yungas valleys. methods: community-based active atl surveillance was performed by the institutions servir, cáritas, and the health services department of la paz, whose files were reviewed retrospectively. a cross-sectional survey was carried out to assess demographic data in two communities. results: two thousand nine hundred nine cases of atl were detected from 2001 to 2006: 2,488 (85.5%) corresponded to lcl and 421 (14.5%) to mcl. a reduction in the proportion of mucosal cases was observed between 2001 and 2006. the proportion of mcl cases increased with age and was higher among males (15.5% versus 12.1%, p=0.018). the rate of positivity via direct observation of the parasite in dermal scrapings and in parasite cultivation was significantly higher for lcl than for mcl (p<0.001 and p=0.009, respectively). the rate of reactivity in the leishmanin skin test was higher in the group with mucosal lesions (p=0.012). the cross-sectional survey showed that 40% of the families had emigrated from the altiplano. conclusions: it is necessary to undertake continuous case detection of atl in the area, where the disease presents a high rate of mucosal cases. increasing incidence seems to be associated with immigration and continuous deforestation to expand the crop-growing areas.

Memórias do Instituto Oswaldo Cruz , 2011, DOI: 10.1590/S0074-02762011000800025
Abstract: lutzomyia longipalpis is the primary vector of the parasite responsible for visceral leishmaniasis in the americas. in the present study, lu. longipalpis was found in a domiciliary area in limón, a district in capira, a region in which cutaneous leishmaniasis is endemic in panama. previously, this species has been found in a humid forest in this same region. finding lu. longipalpis in domiciliary areas indicates that this species may be adapting to new habitats and that it may play a role in the transmission of leishmaniasis in panama.

Memórias do Instituto Oswaldo Cruz , 2005, DOI: 10.1590/S0074-02762005000700006
Abstract: the dispersal pattern of the sand fly lutzomyia neivai was studied through mark-release-recapture experiments in an american cutaneous leishmaniasis endemic rural area in southeastern brazil. over 6500 specimens were marked with fluorescent powder and released in forest edge and peridomicile habitats from august to november 1999, february and april 2000. recapture attempts were made using shannon and cdc traps up to eight successive nights after releases. a total of 493 (7.58%) specimens were recaptured. the number of recaptured males and females of l. neivai in cdc traps was not affected by the distance between the trap and the release points. approximately 90% of males and females recaptured in cdc traps were caught up to 70 m from the release points. the maximum female flight range recorded was 128 m. the average flight range per day was less than 60 m for males and females. of the flies released in forest edge, approximately 16% of the recaptured females were caught in shannon traps in the peridomicile habitat. the results indicate that the movements of l. neivai are spatially focal and the possibility of dispersion from forest to peridomicile habitat may be an important way of contracting leishmaniasis in dwellings.

Abstract: El municipio de Paraty presenta altas tasas de incidencia de Leishmaniasis Cutánea (LC), con un promedio anual de 43.2 casos desde 1985. El municipio presenta gran importancia en la actividad turística por su patrimonio histórico y por sus características paisajísticas. Anualmente recibe miles de turistas internacionales y nacionales. Estudios relacionados con los flebotominos se llevaron a cabo en siete localidades con informes de casos humanos o caninos de LC, con el fin de proporcionar nueva información para ayudar a la prevención de LC. Se recolectaron un total de 3,831 especímenes pertenecientes a siete especies: Nyssomyia intermedia, Migonemyia migonei, Micropygomyia schreiberi, Pintomyia fischeri, Evandromyia tupynambai, Lutzomyia longipalpis y Exapillata firmatoi. La especie N. intermedia ha sido predominante, seguida por M. migonei y L. longipalpis. El pico más alto de actividad de los flebotominos en Ponta da Romana se produjo entre los rangos de 18 a 19 h y 01 a 02 h. n la localidad de Pouso de Cajaíba, los picos se registraron entre 19 a 20 h y 01 a 02 h. Se sugiere que las especies N. intermedia y M. migonei están transmitiendo la Leishmaniasis cutánea americana en áreas endémicas de Paraty, Río de Janeiro, Brasil. The municipality of Paraty has a high incidence of American Cutaneous Leishmaniasis (ACL), with an annual mean of 43.2 cases since 1985. The municipality is of great importance for tourism activities given its historic importance and landscape characteristics. It receives thousands of international and national tourists annually. Studies on the sand fly fauna were carried out in seven localities with reports of human or canine cases of ACL, in order to provide new informatión to help prevent ACL. A total of 3,831 specimens were collected belonging to seven species: Nyssomyia intermedia, Migonemyia migonei, Micropygomyia schreiberi, Pintomyia fischeri, Evandromyia tupynambai, Lutzomyia longipalpis, and Exapillata firmatoi. The species N. intermedia was predominant, followed by M. migonei and L. longipalpis. The major peak of sand fly densities in Ponta da Roman occurred between the ranges of 18 to 19 h and 01 to 02 h. En the locality of Pouso da Cajaíba, the peaks occurred between 19 to 20 h and 01 to 02 h. We suggest that the species N. intermedia and M. migonei are transmitting American cutaneous Leishmaniasis in the endemic areas of Paraty, Rio de Janeiro, Brazil.

Revista Brasileira de Parasitologia Veterinária , 2009, DOI: 10.4322/rbpv.01803006
Abstract: the objective of the present study was to investigate the dynamics and profile of american cutaneous leishmaniasis (acl) in an old colonization area in the state of rio de janeiro. health departments of municipalities in the central-southern region that had notified cases to the ministry of health's notifiable diseases information system between 1997 and 2002 were contacted to obtain data. out of the 119 cases recorded, 51 patients were visited for an interview and inspection of the environment. the cases of acl exhibited a profile similar to that observed in other brazilian cities, affecting individuals of both genders, all age groups and different occupational categories, especially students. risk activities were reported by 56.9% of the interviewees and 84.3% had never left their homeland. water courses, chicken coops, bamboo plantations and different fruit trees including banana plants and mango trees were frequently observed in the surrounding environment. most of the interviewees had not noted any environmental changes prior to becoming sick. domestic animals were present in all homes, but only dogs presented lesions suggestive of the disease. these were on different occasions that rarely preceded or coincided with the human cases. the possible existence of distinct transmission cycles, i.e. one for canines and another for humans, was discussed.
American cutaneous leishmaniasis in dogs from an endemic urban area in Cianorte municipality, Paraná State, Brazil
Cerino, DA;Veloso, J;Perles, TF;Zanzarini, PD;Lonardoni, MVC;Silveira, TGV;
Journal of Venomous Animals and Toxins including Tropical Diseases , 2010, DOI: 10.1590/S1678-91992010000200007
Abstract: american cutaneous leishmaniasis (acl) was investigated in dogs from an urban endemic area in cianorte, paraná state, brazil. of 169 studied dogs, none presented suspected acl lesions. eleven animals (6.6%) had anti-leishmania braziliensis antibodies (titers > 40) detected by the immunofluorescent antibody test (ifat) while four (2.4%) showed l. braziliensis-complex dna by the polymerase chain reaction (pcr). although no associations were found between ifat or pcr results and age, sex, origin, free-roaming animals or length of residence at the address, the majority of ifat- or pcr-positive dogs were from the urban area of the city and were allowed to roam freely beyond their neighborhood. the presence of anti-leishmania braziliensis antibodies and l. braziliensis-complex dna in dogs from this urban area near a native-forest park indicates the importance of following up on these dogs to confirm the acl diagnosis.
