No. of bitstreams: 1 2006-Michelle Gomes Barreto.pdf: 634856 bytes, checksum: 61550da2cbc0a0c4fbc8b6781fe93da0 (MD5) Previous issue date: 2006-07-27 / It was performed a study comparative in the diagnostic of the canine distemper through techniques of Direct Immunofluorescence (IFD), Indirect Immunofluorescence (IFI) and Stain Sellers in samples of nervous tissue of dogs and wild animals that died with suspicion clinical of the viruse. Were utilized 118 samples of central nervous system (SNC) of domestic dogs and 3 wild animals, 2 skunks and 1 monkey, utilizing Ammon?s horn (CA), cerebellum (CB) and brain stem (TE). The TE was the region of larger percentage of positive, following of CA. The comparation between Stain Sellers and IFD, this last demonstrated a large sensitive. The IFI observed what to the realization of the technique was necessary the utilization of fresh materials. The utilization of the 117 samples in conditions of autolysis presented negative result. However 1 sample not autolysate, it was result positive in the 3 brain regions (CA, CB, TE). It was not possible the comparative with the technique of IFI, because in the work the technique alone was possible in materials conserved, with the advantage of a read more easy. In the work was detected also canine distemper in a skunk through technique of IFD. / Foi realizado um estudo comparativo do diagn?stico da cinomose pelas t?cnicas de Imunofluoresc?ncia Direta (IFD), Imunofluoresc?ncia Indireta (IFI) e Colora??o de Sellers em amostras de tecido nervoso de c?es e de animais silvestres que morreram com suspeita cl?nica da virose. Foram utilizados 118 amostras de Sistema nervoso central (SNC) de c?es dom?sticos e de 3 animais silvestres , dois gamb?s e um mico, utilizando-se Corno de Ammon (CA), Cerebelo (CB) e Tronco Encef?lico (TE). O TE foi ? regi?o de maior porcentagem de positivos, seguido do CA. A compara??o entre a Colora??o de Sellers, e a IFD, revelou uma maior sensibilidade nesta ?ltima. Na IFI, observamos que para a realiza??o da t?cnica torna-se necess?rio ? utiliza??o de material fresco. Tendo em vista a utiliza??o das 117 amostras em estado de aut?lise apresentaram resultados negativos e apenas 1 n?o autolisado, teve seu resultado positivo nas 3 regi?es cerebrais (CA, CB e TE). N?o foi poss?vel a compara??o com a t?cnica de IFI, porque nesse trabalho, a t?cnica s? foi poss?vel em materiais conservados, com a vantagem de uma leitura mais f?cil. Nesse trabalho foi detectado tamb?m cinomose em um gamb? pela t?cnica de IFD.

No. of bitstreams: 1 2017 - Elisa Domingues Padua.pdf: 1950908 bytes, checksum: d9644f85d3b5935e0ad3f149d04d4f4b (MD5) Previous issue date: 2017-07-25 / Despite some reports of the occurrence of Leishmaniasis in felines, the literature is scarce with regard to its research on populations of cats from areas endemic to the disease. In this way, the present study aimed to investigate the possibility of infection in cats by means of a rapid qualitative test of the antibody test in Serop?dica and Itagua?, metropolitan region of Rio de Janeiro, an endemic area for tegumentary and visceral canine leishmaniasis Anti-Leishmania chagasi by indirect immunoenzymatic assay (ELISA) and indirect immunofluorescence (RIFI). For this purpose, blood samples were collected and the serum of 255 cats was sent to the Escola Nacional de Sa?de P?blica (FIOCRUZ). In this population of cats five animals (1.9%, 5/255) were reactive to the rapid test (TR DPP?), 44 (17.3%) had anti-Leishmania spp. Identified by the RIFI. The main clinical signs observed in the seropositive animals were ocular secretion (16/44 - 36%), nasal secretion (16/44 - 36%), weight loss (7/44 - 15.9%), alopecia (6/44 - 13 , 6%) and ulcerated skin lesions (5/44 - 11.3%), in addition to hepatosplenomegaly (2/44 - 4.5%), lymphadenomegaly (5/44 - 11.3%), corneal opacity 2/44 - 4.5%) and gingivitis (2/44 - 4.5%). It was not possible to establish a standardization for the ELISA. Detection of anti-Leishmania spp. in felines, calls attention to this species that must be further investigated in relation to its power as a source of infection in relation to the parasite. / Apesar de alguns relatos da ocorr?ncia de Leishmaniose em felinos, a literatura ? escassa no que diz respeito ? sua pesquisa em popula??es de gatos de ?reas end?micas para a doen?a. Desta forma, o presente estudo teve por objetivo pesquisar, em Serop?dica e Itagua?, regi?o metropolitana do Rio de Janeiro, ?rea end?mica para Leishmaniose tegumentar e visceral canina, a possibilidade de infec??o em gatos, por meio de teste r?pido qualitativo, da pesquisa de anticorpos anti-Leishmania chagasi pelas t?cnicas de ensaio imunoenzim?tico indireto (ELISA) e rea??o de imunofluoresc?ncia indireta (RIFI). Para tanto, foram colhidas amostras de sangue e soro de 255 gatos, os quais foram encaminhados ? Escola Nacional de Sa?de P?blica (FIOCRUZ). Nessa popula??o, cinco gatos (1,9%, 5/255) foram reagentes ao teste r?pido (TR DPP?), 44 (17,3%) apresentaram anticorpos anti-Leishmania spp. identificados pela RIFI. Os principais sinais cl?nicos observados nos animais soropositivos foram secre??o ocular (16/44 ? 36%), secre??o nasal (16/44 ? 36%), emagrecimento (7/44 ? 15,9%), alopecia (6/44 ? 13,6%) e les?o ulcerada na pele (5/44 ? 11,3%), al?m de hepatoesplenomegalia (2/44 ? 4,5%), linfadenomegalia (5/44 ? 11,3%), opacidade de c?rnea (2/44 ? 4,5%) e gengivite (2/44 ? 4,5%). N?o foi poss?vel estabelecer uma padroniza??o para o ELISA. A detec??o de anticorpos anti-Leishmania spp. em felinos chama a aten??o para essa esp?cie que deve ser mais investigada em rela??o ao seu poder como fonte de infec??o em rela??o ao parasito.
