25. Vector density and the control of kala-azar in Bihar, India
Bihar, India has been in the grip of kala-azar for many years. Its rampant and severe spread has made life miserable in most parts of the state. Such conditions require a comprehensive understanding of this affliction. The numbers coming out of the districts prone to the disease in the north and south Ganges have provided us with several startling revelation

26. Controle de flebotomíneos (Diptera: Psychodidae) vetores de leishmanioses
Os flebotomíneos são vetores de importância médica e veterinária, podendo transmitir leishmanioses, bartoneloses e algumas arboviroses. A adaptação de algumas espécies a locais que passaram por modificações humanas as aproxima dos domicílios, podendo facilitar a transmissão das doenças, e as estratégias adotadas para seu controle têm sido cont

27. Characterization of chitinase gene from lutzomyia longipalpis:alternative splicing description and search for promoter sequence / Caracterização de gene de quitinase de Lutzomyia longipalpis: descrição de processamento alternativo e busca por seqüência promotora
Leishmaniasis is a disease caused by Leishmania protozoa transmitted by the bite of infected sand flies. Current methods used to combat this illness have been shown to be inefficient, and better knowledge of aspects related to Leishmania-sand fly interaction are necessary for the development of new controlling methods. A cDNA codifying for a midgutspecific c

28. Descripción del ARN de transferencia mitocondrial para Serina (UCN) de Lutzomyia columbiana (Diptera, Psychodidae)
The sand fly Lutzomyia columbiana is considered a suspected vector of Leishmania mexicana and Leishmania braziliensis in Colombia. Lu. columbiana belongs to the Lutzomyia verrucarum species group, which included some sibling species. This has motivated the search for molecular markers to distinguish these taxa. In this paper, we described for the first time

30. Maruins (Ceratopogonidae: Diptera) do estuário do Rio Pará e do litoral do Estado do Pará, Brasil
O presente trabalho teve como objetivo fazer o levantamento das espécies de ceratopogonídeos hematófagos (maruins) em áreas costeiras do Estado do Pará. Foram amostrados dois pontos, um no litoral (Praia do Crispim/Marapanim) e outro no estuário do rio Pará (Outeiro/Belém). As coletas foram feitas mensalmente em 2003 de abril a outubro em Outeiro e n

31. Frequência de anticorpos de Leishmania sp em Rattus norvegicus no município de Belo Horizonte, Minas Gerais
A leishmaniose visceral americana (LVA é uma doença parasitária transmitida por uma protozoário denominado Leishmania chagasi através da picada da fêmea do mosquito hematófago dos gêneros Phlebotomus e Lutzomyia, tendo como principais reservatórios o cão e a raposa. Com o objetivo de verificar a freqüência de anticorpos de Leishmania SP em Rattus

32. Detection of amastigote-like forms in the valve of Phlebotomus papatasi infected with Leishmania major
A massive and homogeneous amount of amastigote-like forms was detected in the stomodeal valve (SV) and the thoracic mid-gut (TMG) of Leishmania major-infected Phlebotomus papatasi, which received a second blood meal 13 to 21 days post-infection on healthy anaesthetized hamsters. After re-feeding, the infected sand flies were dissected out to examine the morp

33. Deltamethrin-impregnated dog collars have a potent anti-feeding and insecticidal effect on Lutzomyia longipalpis and Lutzomyia migonei
Deltamethrin-impregnated PVC dog collars were tested to assess if they were effective in protecting dogs from sand fly bites of Lutzomyia longipalpis and Lu. migonei. A protective effect against Old World species Phlebotomus perniciosus was demonstrated before. Four dogs wearing deltamethrin collars and three dogs wearing untreated collars (not impregnated w

34. Sand fly evolution and its relationship to Leishmania transmission
The evolutionary relationships of sand flies and Leishmania are discussed in this report, which draws distinctions between co-association, co-evolution and co-speciation (or co-cladogenesis). Examples focus on Phlebotomus vectors of Le. infantum and Le. major in the Mediterranean subregion.

35. Delayed-type hypersensitivity to Phlebotomus papatasi sand fly bite: An adaptive response induced by the fly?
The saliva of bloodsucking arthropods contains a large array of pharmacologically active compounds that assist hematophagy. Arthropod saliva is also responsible for causing uncomfortable allergic responses in its vertebrate hosts. In this article, we investigate whether the sand fly Phlebotomus papatasi, known to produce a strong delayed-type hypersensitivit

36. Characterization of a Defensin from the Sand Fly Phlebotomus duboscqi Induced by Challenge with Bacteria or the Protozoan Parasite Leishmania major
Antimicrobial peptides are major components of the innate immune response of epithelial cells. In insect vectors, these peptides may play a role in the control of gut pathogens. We have analyzed antimicrobial peptides produced by the sand fly Phlebotomus duboscqi, after challenge by injected bacteria or feeding with bacteria or the protozoan parasite Leishma
