| Background The study of the distribution and ecology of sandfly species is essential for epidemiological surveillance and estimation of the transmission risk of Leishmania spp. infection. Findings In the present study, sandflies were captured in native fragmented forest areas in Rubião Júnior district, Botucatu municipality, São Paulo state, Brazil, between September 2001 and January 2005. A minimum of two automatic light traps were installed per night from 6 pm to 8 am, in different months, resulting in approximately 900 collecting hours. During this period, 216 sandfly specimens of sixteen species were captured. Pintomyia monticola and Brumptomyia guimaraesi were the most abundant with 56 specimens (25.93%) captured per species, followed by Pintomyia... |

| Cutaneous leishmaniases are anthropozoonoses that involve many species of Leishmania and a wide variety of wild mammalian hosts, thus presenting high importance to public health. This study reports the second case of feline leishmaniasis in Mato Grosso do Sul state, in which Leishmania (Leishmania) amazonensis was found in a domestic cat from Ribas do Rio Pardo. Clinical signs were similar to those observed in other diseases commonly diagnosed in cats, such as cryptococcosis and sporotrichosis. Cutaneous leishmaniasis should, therefore, be added to differential diagnoses by feline veterinary practitioners, and also adequate investigations should be carried out to verify the relevance of domestic cats as L. amazonensis reservoirs. |

| Leishmaniasis is a parasitic zoonosis caused by protozoans of the genus Leishmania transmitted by insects known as phlebotomines, which are found in wild or urban environments. It affects domestic and wild animals and transmission to man happens by accident. The disease occurs in tropical and sub-tropical areas, mainly in Asia, Europe, Africa, and the Americas. There are two forms that affect man: American cutaneous leishmaniasis (ACL) and American visceral leishmaniasis (AVL). The latter is caused by three species of Leishmania: Leishmania (Leishmania) donovani, Leishmania (Leishmania) infantum, and Leishmania (Leishmania) chagasi, which are grouped in the Leishmania (Leishmania) donovani complex. Wild reservoir hosts of L. chagasi known so far are foxes... |

| The endemicity of American cutaneous leishmaniasis (ACL) in the Cianorte municipality, Paraná State the occurrence of human cases with the probable infection locus in the urban area, the presence of a permanently preserved modified native forest in the urban perimeter, and the lack of knowledge of the fauna of sand flies in the municipality provided the impetus for this study. The objective of this study was to assess the fauna, frequency and seasonality of the sand flies in the peridomicile, forest and urban area of this municipality. Sand flies were collected using Falcão light traps installed in the peridomicile and forest, from July 2005 to June 2006. A total of 755 sand flies were collected; Nyssomyia whitmani (Antunes & Coutinho) (84.0%),... |

| A cross-sectional survey of 29 randomly selected schools, comprising 11 (37.9%) post-primary schools and 18 (62.1%) primary schools from eight Local Government Areas (LGAs) (approximately 35% of the 23 LGAs) of Kaduna State was undertaken to determine the prevalence status of cutaneous leishmaniasis between May and October, 1997. The disease occurrence was detected by on-sight diagnosis of active lesions and scars, and observed leishmanial cases were recorded for patients who gave description of symptoms that fitted into clinical symptoms of cutaneous leishmaniasis. The recorded cases were confirmed by parasitological examination of Giemsa-stained lesion smears for amastigotes in the laboratory. The Chi-square analysis of the result revealed that there was... |

| Captures with black and white Shannon traps were undertaken to identify aspects of the behavior of the two cryptic and sympatric species implicated as vectors of cutaneous leishmaniasis, Nyssomyia intermedia (Lutz & Neiva, 1912) and Nyssomyia neivai (Pinto, 1926). The traps were installed side by side, monthly, from July 2001 to June 2002, from 18 to 07 hours, in a peridomicile of Iporanga municipality, state of São Paulo, Brazil. A total of 2,142 specimens were captured, Ny. intermedia (47.4%) and Ny. neivai (50.5%). The white trap was more attractive to both sexes of both species. Males of Ny. neivai predominated (70%) over those of Ny. intermedia on the two traps; on the black trap, the females of Ny. intermedia predominated (63.3%) over those... |

| ABSTRACT Treatment of cutaneous leishmaniasis (CL) is difficult due to the scarce number of drugs able to eliminate completely the intracellular form of the parasite. In the present study, the aim was to evaluate: i) phytochemical properties of extracts from Libidibia ferrea; ii) antileishmanial activity of extracts from L. ferrea against promastigotes and amastigotes of Leishmania (Leishmania) amazonensis and Leishmania (Viannia) guyanensis; iii) the effects of topical treatment using hydrogel containing active extract of L. ferrea on golden hamsters infected with L. (L.) amazonensis. Extracts from leaves, branches and fruits of L. ferrea were obtained with hexane and methanol and were tested by in vitro assays in promastigotes and murine macrophages J774... |

| The purpose of this work was to verify the occurrence of Leishmania in naturally infected sandflies. The insects were collected with Falcão, Shannon and HP light-traps, in Doutor Camargo and Maringá municipalities between November 2004 and October 2005. Of the 11,033 sandflies collected in Doutor Camargo, 2,133 surviving females were dissected, particularly those of the Nyssomyia neivai species (86.87%). In Maringá, 136 sandflies were collected, of which 79 N. whitmani females and 1 Migonemyia migonei female were dissected. The dissected insects were identified and stored in the pools of 10 specimens. The PCR was carried out on 1,190 females of N. neivai and 190 of N. whitmani from Doutor Camargo, and on 30 of N. whitmani from Maringá, using the primers... |

| We evaluated the effectiveness of serological and parasitological methods for cutaneous leishmaniasis (CL) diagnosis in patients from the central region of Paraná state, southern Brazil. Five groups were compared: clinical diagnosis, parasitological diagnosis, communicants, inhabitants of a non-endemic area and carriers of other etiologies. Two antigens were prepared from promastigotes of Leishmania (Viannia) braziliensis and Leishmania (Leishmania) amazonensis for indirect immunofluorescence assay, ELISA and immunoblotting. The parasitological approaches detected 79.3% of the patients with a clinical diagnosis; the parasites were identified by PCR as L. (V.) braziliensis. Serological methods showed 95% sensitivity for homologous antigens. Immunoblotting... |

| The pentavalent antimonial (Sb5+) meglumine is the drug of choice for the treatment of cutaneous leishmaniasis (CL) in Brazil. Although the cardiotoxicity of high-dose, long-term Sb5+ therapy is well known, the use of low-dose, short-term meglumine has been considered to be safe and relatively free from significant cardiac effects. In order to investigate the cardiotoxicity of low-dose, short-term therapy with meglumine in cutaneous leishmaniasis, 62 CL patients treated with meglumine were studied. A standard ECG was obtained before and immediately after the first cycle of treatment (15 mg Sb5+ kg-1 day-1). The electrocardiographic interpretation was carried out blindly by two investigators using the Minnesota Code. There were no significant differences in... |

| In order to study the role of natural killer (NK) cells during the early period of Leishmania infection, BALB/c mice were selectively and permanently depleted of NK cells by injection with 90Sr and subsequently infected with Leishmania (Leishmania) amazonensis (HSJD-1 strain). 90Sr is known to selectively deplete NK cells, leaving an intact T- and B-cell compartment and preserving the ability to produce both interferon alpha and IL-2. This method of depletion has advantages when compared with depletion using anti-NK cell monoclonal antibodies because the effect is permanent and neither activates complement nor provokes massive cell death. In the present study, after one month of treatment with 90Sr, the depletion of NK cells was shown by a more than... |

| Complement-depleted and -non-depleted BALB/c mice were inoculated with Leishmania (Leishmania) amazonensis promastigotes into the hind footpad to study the role of the complement system in cutaneous leishmaniasis. Total serum complement activity was measured by hemolytic assay and C3 fragment deposit at the inoculation site was determined by direct immunofluorescence in the early period of infection, i.e., at 3, 24, 48 h and 7 days post-infection. The inflammatory reaction and the parasite burden were evaluated in the skin lesion at 7 and 30 days post-infection. Total serum complement activity decreased in the early phase of infection, from 3 to 24 h, in non-depleted mice compared to non-infected and non-depleted mice. C3 fragment deposit at the site of... |
