| Foram estudados 268 indivíduos (198 homens e 70 mulheres), residentes no Amazonas, com resultados hemoscópicos positivos de malária, diagnosticados pela Fundação Nacional de Saúde — FNS/Manaus. A avaliação antropométrica foi universal, envolvendo as medidas de Peso, Altura, índice de Massa Corpórea (IMC), Prega Cutânea Triciptal (PCT), Circunferência Braquial (CB) e Circunferência Muscular do Braço (CMB). O universo estudado foi ainda subamostrado para avaliação Hematológica, Bioquímica (121 indivíduos) e Parasitológica (55 indivíduos). A análise dos resultados evidencia que apesar da presença da malária e das precárias condições de vida dos doentes, constatou-se que o Peso, Altura, IMC, CB e CMB apresentaram valores médios considerados normais,... |

| Um inquérito entomològico foi realizado na área de influência da Hidrelétrica de Balbina, situada a 146 km de Manaus, Amazonas, para avaliar os possíveis efeitos sobre as populações de Anophelese de outros culicídeos. Cinco anos após a formação do lago, An. darlingi, An. nuneztovarie An. triannulatusforam as espécies encontradas com maior freqüência nas coletas realizadas em 1. Rodovia BR-174, 2. Acceso á Usina Hidrelétrica de Balbina e 3. Área Uatumã-Morena. Para cada espécie os índices mosquito/homem/hora foram respectivamente: Area 1 - 0,57; 12,85; 0,43. Área 2 - 0; 3,75; 0,18 e Área 3 - 0; 26,38; 0,34. Representantes das duas primeiras espécies se mostraram positivas para Plasmodiumcom testes imunoenzimáticos. A prevalência de mosquitos positivos foi... |

| Malaria is responsible for more than 1.5 million deaths each year, especially among children (Snow et al. 2005). Despite of the severity of malaria situation and great effort to the development of new drug targets (Yuan et al. 2011) there is still a relative low investment toward antimalarial drugs. Briefly there are targets classes of antimalarial drugs currently being tested including: kinases, proteases, ion channel of GPCR, nuclear receptor, among others (Gamo et al. 2010). Here we review malaria signal transduction pathways in Red Blood Cells (RBC) as well as infected RBCs and endothelial cells interactions, namely cytoadherence. The last process is thought to play an important role in the pathogenesis of severe malaria. The molecules displayed on the... |

| Malaria remains the most prevalent and devastating parasitic disease worldwide. Vaccination is considered to be an approach that will complement other strategies for prevention and control of the disease in the future. In the last 10 years, intense studies aimed at the development of a malaria vaccine have provided important knowledge of the nature of the host immunological mechanisms of protection and their respective target antigens. It became well established that protective immune responses can be generated against the distinct stages of Plasmodium. However, in general, protective immune responses are directed at stage-specific antigens. The elucidation of the primary structure of these antigens made possible the generation of synthetic and recombinant... |

| Birds from the high Andes in the National Natural Park Chingaza, Colombia, were surveyed for blood parasites in April 2002 and March 2003. Of 136 birds examined, representing 40 species of 14 families, 38 were infected with blood parasites. Parasites of the genera Leucocytozoon (21.3% prevalence), Plasmodium (8.1%), Hepatozoon (2.9%), Microfilariae (2.9%) and Haemoproteus (1.5%) were recorded. Twenty five avian species in this survey were examined for blood parasites for the first time and 49 new parasite-host associations were identified. The most striking observation of this study was the high prevalence of Leucocytozoon spp. In the Neotropics, the prevalence of Leucocytozoon spp. has not been reported to be greater than 0.2% and is closely associated... |

| Malaria is a parasitic disease caused by organisms of the genus Plasmodium. The present study examined wild and cultivated plants used to treat malaria and associated symptoms by riparian communities in the Municipalities of Pauini and Xapuri in Amazonas and Acre states, respectively. During the year 2013 86 persons were interviewed in 9 rural communities in Pauini and Xapuri that were known for their knowledge and use of medicinal plants, After each interview, walks were made (walk in the woods), with the main informant of the family, for identification of plants and to collect the samples of the species indicated. A total of 86 plant species were indicated by seringueiros and ribeirinhos for the treatment of malaria and for associated symptoms, while 26... |

| Autochthonous malaria cases in the state of Espírito Santo, Brazil, are distributed in mountainous regions surrounded by the Atlantic Forest. While some aspects of this disease are unclear, detection of possible vector species can help to elucidate epidemiological uncertainties. Entomological and natural infection studies were carried out using anophelines (Diptera: Culicidae) captured in the municipality of Santa Tereza, ES. Monthly captures were made from March 2004 to February 2006. CDC-CO2 traps were used from dusk (6:00 P.M.) to dawn (6:00 A.M.) to capture anophelines in the following habitats: near the houses, in open areas (at ground level) and inside, and at the margins of the forest (canopy and ground level). Shannon light traps were also used at... |

| Malaria kills millions of people every year and the current strategies to control the disease, such as insecticides and drugs have not been completely efficient. Because of that, novel means to fight against malaria are of utmost importance. Advances in the study of the mosquito vector and its interactions with the malaria parasite made scientists think that it is possible to genetically manipulate the mosquitoes to make them inefficient vectors. Here we review the advances on the introduction of foreign genes into the mosquito germ line, the characterization of tissue-specific promoters, the identification of gene products that block development of the parasite in the mosquito, and we discuss the recent generation of transgenic mosquitoes impaired for... |

| A new staining technique of 'thick smears' was developed tor diagnosis of malaria using transmission fluorescence microscopy. Plasmodium falciparum cultured in vitro was used as a model. The infected blood was mixed 1 : 1 -1 :2 with acridine orange (AO) solution (final concentrations of 50-lOOu.g/ml in 0.01 M Tris-HCI buffer or in PBS, pH 7.0-7.5). Immediately or several minutes later, haemolyzed or non-haemolyzed 'thick smears' were observed directly by fluorescence microscopy using an interference filter specially designed for excitation of AO or commercially available, three (interference-, glass- and triacetyl cellulose film-) types of B-excitation filters with halogen- or daylight-illuminated microscopes. All of these filters were capable of detecting... |

| This study compared the distributions of ten species of Liolaemus lizards in the central Chilean Andes to the distributions of four types of parasites: malaria-causing Plasmodium, gut nematodes, ticks, and mites. We wanted to see if parasite numbers might be a factor in determining distributional limits of the lizards. We found that there was no evidence of malarial infestation of the lizards, that ticks were almost absent, that more often than not mite numbers decreased at the distributional limits of the lizards, and that gut nematodes confined to the herbivorous lizards in our sample may well be beneficial rather than detrimental. Rather than parasitism, other biotic interactions (e.g., predation or competition) are more likely candidates as factors... |
