The spiny rat Proechimys guyannensis (Rodentia: Echimydae) fails to respond to intradermal inoculation with Leishmania (Viannia) braziliensis Acta Amazonica
PASSOS,Stela Rechinelli; MADUREIRA,Ana Paula; ALMEIDA,Sayanne Luns Hatum de; ZANINI,Marcos Santos.
Leishmaniasis a disease of worldwide occurrence is caused by protozoa of the Leishmania genus. In Brazil, Leishmania (Viannia) braziliensis is the main parasite responsible for the American cutaneous leishmaniasis. Main hosts of this protozoa are small wild mammals particularly marsupials and rodents. The aim of this study was to evaluate if spiny rat Proechimys guyannensis (Rodentia: Echimydae) has role in the cycle of the American cutaneous leishmaniasis caused by L. (V.) braziliensis. Thus, promastigotes (the flagellate stage) of Leishmania (Viannia) braziliensis were used to inoculate seven spiny rats (Proechimys guyannensis). After inoculated intradermal at the ear pinna, nose and plantar pad, the rats were monitored for 180 days. Tissue samples...

TOXIC ACTIVITY OF PYRETHROIDS IN Lutzomyia longipalpis (DIPTERA: PSYCHODIDAE) FROM MAGDALENA RIVER BASIN, COLOMBIA Acta biol.Colomb.
SANTAMARIA,Erika; MARCELÓ,Catalina.
ABSTRACT The study aimed to determine the toxicity of lambda-cyhalothrin, alpha-cypermethrin, and deltamethrin in L. longipalpis, through concentration-mortality bioassays. The test here was performed following WHO guidelines, but instead of using exposure WHO recipients and impregnated papers, 250 ml Wheaton glass bottles treated with 1 ml of insecticide solution were used. Batches of ten females of L. longipalpis were exposed to five concentrations of each pyrethroid that caused between 5 and 100 % mortality in this species. After 1 h of exposure, the females were transferred to observation recipients, and mortality was recorded 24 h later. The lethal concentrations (g/ml) that killed 50 and 95 % (LC50 and LC95) of the exposed L. longipalpis females were...

Multivariate optimization of a method for antimony determination by hydride generation atomic fluorescence spectrometry in hair samples of patients undergoing chemotherapy against Leishmaniasis Anais da ABC (AABC)
CARDOZO,MANUELLE C.; CAVALCANTE,DANNUZA D.; SILVA,DANIEL L.F.; SANTOS,WALTER N.L. DOS; BEZERRA,MARCOS A..
ABSTRACT A method was developed for determination of total antimony in hair samples from patients undergoing chemotherapy against Leishmaniasis based on the administration of pentavalent antimonial drugs. The method is based on microwave assisted digestion of the samples in a pressurized system, reduction of Sb5+ to Sb3+ with KI solution (10% w/v) in ascorbic acid (2%, w/v) and its subsequent determination by hydride generation atomic fluorescence spectrometry (HG-AFS). The proportions of each component (HCl, HNO3 and water) used in the digestion were studied applying a constrained mixtures design. The optimal proportions found were 50% water, 25% HNO3 and 25% HCl. Variables involved in the generation of antimony hydride were optimized using a Doehlert...

Silver and gold nanoparticles from tannic acid: synthesis, characterization and evaluation of antileishmanial and cytotoxic activities Anais da ABC (AABC)
LOPES,LOURDES C.S.; BRITO,LUCAS M.; BEZERRA,THAYLLAN T.; GOMES,KLEYTON N.; CARVALHO,FERNANDO A. DE A.; CHAVES,MARIANA HELENA; CANTANHÊDE,WELTER.
Abstract Gold (Au0) and silver (Ag0) nanoparticles were synthesized using tannic acid (TA) as both reducing and stabilizer. Nanoparticles formation, stability, and interaction with TA were compared to citrate-coated nanoparticles and monitored by UV-Vis, zeta potential, and transmission electron microscopy. TA coating resulted in a red-shift and broadening of bands compared to citrate-coated nanoparticles (NPs-Cit). AgNPs-TA and AuNPs-TA are negatively charged with mean surface charge of -29.4 mV and -29.6 mV, respectively. TEM images showed polydispersety of AuNPs-TA (6-42 nm) and aggregation of AgNPs-TA (12-71 nm). In vitro assays of Leishmania amazonensis promastigotes showed an increment of antileishmanial activity for AgNPs-TA in relation to...

Inhibition of caspase-8 activity reduces IFN-gamma expression by T cells from Leishmania major infection Anais da ABC (AABC)
Pereira,Wânia F.; Guillermo,Landi V.C.; Ribeiro-Gomes,Flávia L.; Lopes,Marcela F..
Following infection with Leishmania major, T cell activation and apoptosis can be detected in draining lymph nodes of C57BL/6-infected mice. We investigated the mechanisms involved in apoptosis and cytokine expression following Tcellactivation. After two weeks of infection, apoptotic T cells were not detected in draining lymph nodes but activation with anti-CD3 induced apoptosis in both CD4 and CD8 T cells. Treatment with anti-FasLigand, caspase-8 or caspase- 9 inhibitors did not block activation-induced T-cell death. We also investigated whether the blockade of caspase-8 activity would affect the expression of type-1 or type-2 cytokines. At early stages of infection, both CD4 and CD8 T cells expressed IFN-gamma upon activation. Treatment with the...

Toxicity of Bacillus species to larvae of Lutzomyia longipalpis (L. & N.) (Diptera: Psychodidae: Phlebotominae) Anais da SEB
Wermelinger,Eduardo D.; Zanuncio,José C.; Rangel,Elizabeth F.; Cecon,Paulo R.; Rabinovitch,Leon.
A study was conducted to compare the susceptibility of third instar larvae of Lutzomyia longipalpis (L. & N.) (Diptera: Psychodidae: Phlebotominae), the vector of the American visceral leishmaniasis to two strains of Bacillus thuringiensis serovar israelensis, one strain of Bacillus sphaericus (all pathogenic to Diptera Culicidae) and a strain of B. thuringiensis ser. morrisoni (pathogenic to larvae of Anticarsia gemmatalis (Hübner) (Lepidoptera: Noctuidae)). Larvae of L. longipalpis showed similar susceptibility to the two strains of B. thruringiensis ser. israelensis, while B. sphaericus and B. thuringiensis ser. morrisoni showed low and no larvicidal effect to this vector, respectively.

Sant’Ana,J.A.P.; Lima,W.G.; Oliveira,M.R.; Simões,L.A.; Michalick,M.S.M.; Melo,M.N.; Tafuri,W.L.; Tafuri,Wg.L..
The histopathological description of intralobular hepatic granulomas in animals with a defined clinical status (asymptomatic, oligosymptomatic and symptomatic animals) was reported. Seventy-one mongrel dogs naturally infected with Leishmania chagasi were obtained from two Brazilian endemic areas: João Pessoa, PB and Belo Horizonte, MG. The hepatic parasite load was determined and compared to granuloma formation. Liver fragments from all infected animals showed remarkable leishmaniotic granulomatous inflammatory reaction. Granulomas with variable size were constituted by macrophages (parasitized or not with amastigotes of L. chagasi), some epithelioid cells, small numbers of lymphocytes, plasma cells, and rare neutrophils. Asymptomatic dogs had higher...

ABSTRACT Visceral leishmaniasis (VL) has spread rapidly across cities in the metropolitan region of Belo Horizonte. The aim of this study was to investigate VL dynamics in a prospective cohort study of dogs in Juatuba, between 2010 and 2011, to confirm the incidence of Leishmania infantum, and to assess possible risk factors associated with infection. An observational and prospective closed cohort study was performed using serology testing in dogs, randomly selected from the whole municipality. All seronegative dogs, or dogs with inconclusive results were monitored using indirect immunofluorescence (IIF) at 6-month intervals. The dog's owners completed a semi-structured questionnaire to assess possible causal factors of seroconversion, and the responses...

The cytotoxic and antileishmanial activity of extracts and fractions of leaves and fruits of Azadirachta indica (A Juss.) Biol. Res.
Carneiro,Sabrina M. P; Carvalho,Fernando A. A; Santana,Lorena C. L. R; Sousa,Alessian P. L; Neto,José M. M; Chaves,Mariana H.
The leishmaniases are severe parasitic diseases that occur worldwide, caused by protozoa of the genus Leishmania. Studies with medicinal plants can lead to a range of possibilities for treating and improving the patients' quality of life. Research on Azadirachta indica fractions and extracts has shown that they have excellent anti-leishmanial activity based on bioactivity-guided fractionation of ethanolic extracts of leaves and seeds and in vitro activity against promastigotes. In this research the most efficient extracts and fractions were selected for tests on intracellular amastigotes of Leishmania amazonensis. The ethanolic extract of the leaves and dichloromethane and chloroform fractions had IC50 values of 38, 3.9 and 1.2 μg/mL for...

A brief inventory of sand flies (Diptera, Psychodidae) from the National Forest of the Rio Preto, state of the Espírito Santo, southeastern Brazil Biota Neotropica
Pinto,Israel de Souza; Tonini,João Filipe Riva; Ferreira,Adelson Luiz; Falqueto,Aloísio.
The inventories on sand flies are usually conducted for a long period in leishmaniasis-endemic regions. Thus, there is little data on the sand fly fauna in areas where no leishmaniasis cases have been reported. Therefore, we conducted an inventory to study the sand fly fauna in the National Forest of Rio Preto (NFRP). We carried out a brief inventory by using four CDC light traps in 2009 during winter and summer. We collected 1,403 sand flies belonging to 11 genera and 22 species. As expected, we did not find in the NFRP region sand flies species that have been reported as vectors of Leishmania. However, we found some species of sand flies with few records and that rarely have been reported in southeastern Brazil. Nevertheless, the diversity and species...
