Item Acesso aberto (Open Access) Avaliação do nível de concordância do teste imunocromatográfico OptiMAL-IT® e a gota espessa no diagnóstico da malária, no município de Mazagão-AP, Brasil(Universidade Federal do Pará, 2007) FADUL, Danielle Scerne; COUTO, Álvaro Augusto Ribeiro D'Almeida; http://lattes.cnpq.br/3800209721205388The precocious diagnosis and the opportune treatment of the cases of malaria is one of the main strategies for the control of the disease. Several alternatives for the traditional microscopic diagnosis were proposed in the last years, the Immunochromatographic tests that capture white antigens of the parasites of the malaria they are being proposed, as the test OptiMAL-IT® that captures the lactic desidrogenase of the Plasmodium sp.. The study had as objective the evaluation of the level of agreement between the Immunochromatographic test (OptiMAL-IT®) and the thick drop for the diagnosis of the malaria in the City of Mazagão – Amapá, Brazil. 413 individuals were analyzed with malaria sintomatology that had looked for the service of the unit of health service of the city, with age among 01-68 years. The results of the OptiMAL-IT® test were compared with the obtained results, of the same samples, through the thick drop red-faced by the Giemsa. Of the 413 patients suspicious to present malaria, 317(76.8%) were positive through GE and 311 (75.3%) were positive for TDR OptiMAL-IT®. Of the positive blades of GE, had been found 27.4% of P. falciparum and 72.6% of P. vivax . The OptiMAL-IT® test detected 27.7% of P. falciparum and 72.3% of P. vivax. The sensibility obtained with TDR for P. falciparum was of 97.7% and for P. vivax was of 98.2%, the global sensibility of TDR was of 98.1% and the global specificity for both the species was of 100%. They were found preditivos values positive and negative of 100% and 94.1%, respectively. The OptiMAL-IT® test had a high agreement with thick drop, it is specific and efficient. It can be used in the diagnosis of malaria in the situations where microscopy is not available.Item Acesso aberto (Open Access) Epidemiologia molecular do Vírus linfotrópico de células T humanas - HTLV 1/2 no Estado do Amapá-Brasil(Universidade Federal do Pará, 2006) SILVA, Ivanete do Socorro Pinheiro da; ISHAK, Marluísa de Oliveira Guimarães; http://lattes.cnpq.br/2847150361567807The geographical distribution of the infection by human T-cell lymphotropic virus 1/2 – HTLV 1 / 2 is extensive, nevertheless, there are areas that are more endemic and have more particularities depending on the HTLV type. The HTLV 1 shows a bigger occurrence in south west of Japan, Caribbean, Central America, in different regions of South America and in parts of Central, as well as in western Africa, while HTLV-2, seems to assault distinct groups of people, such as Indians native people from North, Central and South America, Pigmies from Central Africa, Mongols in Asia as well as in infecting drug users. The present work had as objective describing HTLV molecular epidemiology, in three different populations the State of Amapá, they are: HIV/IDS positive patients, Afro-descenig population and individuals assisted of Public Health Center Laboratory of Amapá – LACEN-AP, directed for diagnosis of HTLV. The samples were tested for the presence of virus using serological (ELISA and Western blot) and molecular assays (gene amplification and restriction fragment length polymorphism from pX and env for the analysis of polimorfismo o restriction fragments for endonuclease action. The obtained results in different populations are In the population of HIV infected people, all the samples were negative; in the Afro-desceding population, only one sample was positive confirmed by serological test (ELISA), but negative according to western blot test and submitted to the molecular analysis, there wast not amplification. However, among samples of individuals directed for diagnosis of HTLV, 06 (six) were positive, 5(five) out of 6/them were confirmed by western blot test. The molecular result demonstrated the presence of HTLV-1.
