“…A leishmaniose tegumentar (LT) é uma doença endêmica no Brasil (Coutinho et al, 1981;Guimarães et al, 1983;Grimaldi et al, 1989), com número crescente de casos notificados (Vieira et al, 1990;FNS, 1993), em áreas que sofreram grandes alterações antrópicas (Dias et al, 1977;Barreto et al, 1984;Barros et al, 1985). No Noroeste do Estado do Paraná a doença tem perfil endêmico (Verzignassi et al, 1988;Teodoro et al, 1991;Silveira et al, 1992Silveira et al, , 1994, mas nos úl-timos três anos a notificação de casos aumentou significativamente (comunicação pessoal de E.

Tegumentary and visceral leishmaniases in Brazil: emerging anthropozoonosis and possibilities for their control

in Brazil -Emerging Anthropozoonosis and Possibilities for Their Control. Cad. Saúde Públ., Rio de Janeiro, 10 (supplement 2): [359][360][361][362][363][364][365][366][367][368][369][370][371][372][373][374][375] 1994. The existence of a number of different species of Leishmania, the persistent increase in the infection rate of diseases caused by this parasite (tegumentary and visceral forms), the different epidemiological situations found in regions of both recent and older colonization, and the trend towards urbanization have led to the adoption of different strategies to control leishmaniases in Brazil. The control measures involve studies related to the parasite, vectors, sources of infection (animal and human), clinical aspects, geographical distribution, historical and socioeconomic factors, integration of health services, and adequate technologies for diagnosis, treatment, and immunoprophylaxis. Finally, successful control requires work with human communities, involving education, provision of information, health promotion, and participation of these communities in the planning, development, and maintenance of control programs.

“…Eduado de Alencar 10 reported only 2,490 clinical cases in the seven-year period between 1953 and 1960, whereas 9,295 cases of VL were reported between 1983 and 1988. 11 Recently, Momen 15 reported that more than 3,000 new cases were diagnosed in 1994 alone. Furthermore, VL has traditionally been a rural disease, but the number of urban cases reported is steadily increasing.…”

“…More than 90% of the VL cases reported from Latin America are in Brazil. 8 In Brazil, VL is endemic in the northeastern part of the country, particularly in the states of Bahia, Piauí, Maranhão, and Ceará, [9][10][11] and in the southeastern region. 12 There is a great deal of variation in number of cases reported and the epidemiology of VL in different parts of Brazil.…”

Abstract. Eleven populations of Lutzomyia longipalpis (Lutz & Neiva), the sand fly vector of Leishmania chagasi, from different areas of Brazil were analyzed for genetic variation at 16 enzyme loci. In this region, the prevalence of visceral leishmaniasis (VL) caused by L. chagasi is spotty and reproductive isolation among populations of Lu. longipalpis has been reported. It is thought that morphologically similar cryptic species with varying vectorial capacity may be responsible for the discontinuous distribution of VL. The aim was to study the genetic structure of populations within this region and to identify demes that may represent sibling species. Genotypic frequencies within populations were in close compliance to Hardy-Weinberg expectations, suggesting there are no sympatric species among these 11 populations. Levels of genetic distance between pairs of populations were very low (Ͻ 0.03), consistent with local populations within a single sand fly species. When genotypic frequency data for all populations were pooled, 9 of the 13 polymorphic loci deviated from Hardy-Weinberg expectations, indicating some degree of genetic substructuring. Estimates of effective migration rates (N e m) among all populations were low, 2.73, suggesting that gene flow is restricted among populations, which is probably the reason for the observed genetic substructuring.
