The goal of this study was to detect molecularly hemoplasmas infection in sheltered dogs in Metropolitan region of Rio de Janeiro, linking it to hematological, biochemical and clinical data changes. Of 222 dogs sampled, 20,27% (45/222) were positive by the Polymerase Chain Reaction Real Time (qPCR) for Mycoplasma spp.. The frequency of hemoplasma species infection by PCR using species-specific oligonucleotides, was 13,06% (29/222), 0% (0/222) and 2,25% (5/222) respectively for M. haemocanis (Mhc), ?Candidatus M. turicensis? (Cmt) and ?Candidatus Mycoplasma haematoparvum / haemominutum? (Cmhp / m). There for e M. haemocanis presented the highest incidence in the dogs population studied. Coinfections were identified between Cmhp/m and Mhc 1,35% (3/222). Regarding hematological alterations associated with infection by Mycoplasma spp., hyperproteinemia on plasma was detected (p = 0,0010). It was not observed an association between hemoplasmas infection and the occurrence of anemia and leukocyte changes. Changes in serum biochemistry showed a significant difference in serum protein (p = 0,0291), globulin (p = 0,0253), creatinine (p = 0,0279) and alkaline phosphatase (p = 0,0242). Additionally the azotemia was statistically (p = 0,0023) associated with the infection. The results obtained in the evaluation of Mhc positive dogs demonstrated no significant difference in plasma total protein (p = 0,0012) and hyperproteinaemia was associated with infection (p = 0,0238). There were significant differences in alkaline phosphatase parameter (p = 0,0173) and urea (p = 0,0401), with azotemia is associated shall infection (p = 0,0061). The results observed in the evaluation of positive dogs for (Cmhp / m) show that ALT (alanine aminotransferase) was associated with infection (p = 0,0301). As for factors associated with infection by Mycoplasma spp., only gender (p = 0,0062) and age (p = 0,0041) were associated with infec??o.N?o are statistically associated with the historical agent of fights, access to street, castration, history fleas, ticks history, presence of fleas and ticks. The frequency of the main findings of anamanse and clinical examination of the dogs positive for Mycoplasma spp . were lymphadenopathy (37,8% ) , skin lesions compatible with scabies ( 28,9%) , TPC > 2 ( 31,1% ) , oral affections ( 15,5%) of hist?rico ehrlichiosis ( 13,3%) . Consequently, knowledge of the disease and the factors related to their occurrence are necessary for the adoption of preventive measures aimed at animal health. / Os hemoparasitos micoplasmas hemotr?ficos s?o bact?rias gram-negativas, que se fixam obrigatoriamente na superf?cie dos eritr?citos, levando a deforma??o desta. O objetivo do presente estudo foi detectar molecularmente a infec??o por hemoplasmas em c?es de abrigos da Regi?o Metropolitana do Rio de Janeiro, associando-a aos dados hematol?gicos, bioqu?micos e altera??es cl?nicas. Dos 222 c?es amostrados, 20,27% (45/222) foram positivos pela Rea??o em Cadeia da Polimerase em Tempo Real (qPCR) para Mycoplasma spp.. A frequ?ncia de infec??o das esp?cies de hemoplasma pela PCR, utilizando oligonucleot?deos esp?cie-espec?ficos, foi 13,06% (29/222), 0% (0/222) e 2,25% (5/222), respectivamente para M. haemocanis (Mhc), ?Candidatus M. turicensis (CMt) e ?Candidatus Mycoplasma haematoparvum/ haemominutum? (CMhp/m). M. haemocanis constitui, portanto, a esp?cie de maior ocorr?ncia na popula??o de c?es estudada. Foram identificadas coinfec??es entre CMhp/m e Mhc em 1,35% (3/222) dos c?es. No tocante ?s altera??es hematol?gicas associadas ? infec??o por Mycoplasma spp., constatou-se hiperproteinemia plasm?tica refratom?trica (p=0,0010). N?o foi observada associa??o entre a infec??o por hemoplasmas e a ocorr?ncia de anemia ou altera??es leucocit?rias. Nas altera??es da bioqu?mica sangu?nea, evidenciou-se diferen?a significativa na prote?na s?rica (p=0,0291), globulina (p=0,0253), creatinina (p=0,0279), fosfatase alcalina (p=0,0242). Adicionalmente, a azotemia foi estatisticamente (p=0,0023) associada ? infec??o. Os resultados observados na avalia??o de c?es positivos para Mhc demonstram haver diferen?a significativa na prote?na plasm?tica total (p=0,0012) e hiperproteinemia foi associada ? infec??o (p=0,0238). Houve diferen?a significativa no par?metro fosfatase alcalina (p=0,0173) e ur?ia (p=0,0401), com a azotemia sendo associada ? infec??o (p=0,0061). Os resultados observados na avalia??o de c?es positivos para CMhp/hm demonstram que a ALT (alanina aminotransferase) foi associada ? infec??o (p=0,0301). Quanto aos fatores associados ? infec??o por Mycoplasma spp., apenas g?nero (p=0,0062) e idade (p=0,0041) foram associadas ? infec??o. N?o apresentaram associa??o estat?stica com o agente hist?rico de brigas, acesso a rua, castra??o, hist?rico de pulgas, hist?rico de carrapatos, presen?a de pulgas e presen?a de carrapatos. A frequ?ncia dos principais achados de anamanse e exame cl?nico dos c?es positivos para Mycoplasma spp. foram a linfadenopatia (37,8%), les?es de pele compat?veis com sarna (28,9%), TPC >2 (31,1%), afec??es bucais (15,5%) e hist?rico de erlichiose (13,3%). Consequentemente, o conhecimento da doen?a bem como dos fatores relacionados ? sua ocorr?ncia s?o necess?rios para a ado??o de medidas preventivas visando ? sa?de animal.

In dogs, hemoplasma infection can cause hemolytic anemia in the acute phase, while in the chronic phase the signs are generally inapparent, and immunosuppression can trigger the acute disease. The present study aimed to detect molecularly the presence of hemotrophic mycoplasma agents in domestic dogs from the urban and rural areas of Aragua?na, Tocantins and, in addition, to correlate hematological alterations and factors associated with natural infection. In the analysis of the results, 2.9% (3/105) of the dogs sampled from the urban area and 24.49% (24/99) from the rural area were positive for Mycoplasma spp. by the Real Time Polymerase Chain Reaction (qPCR). The frequency of hemoplasmas species infection by PCR using species-specific oligonucleotides was 1.9% (2/105) and 13.26% (13/99) for Mycoplasma haemocanis in the urban and rural areas, respectively. No positive dogs were observed for ?Candidatus Mycoplasma turicensis? and ?Candidatus Mycoplasma haematoparvum?/?Candidatus Mycoplasma haemominutum? in both areas studied. Regarding hematological alterations, there was no statistical association with the infection by Mycoplasma spp. Similarly, among the analyzed variables (age, gender, racial pattern, site cleanliness and housing), no statistical correlation was observed in either urban or rural areas. This is the first report of the molecular detection of Mycoplasma haemocanis in dogs from Tocantins and opens up prospects for future studies in this group of hemotrophic agents. / Os hemoparasitos micoplasmas hemotr?ficos s?o organismos pleom?rficos, epicelulares, Gram negativos, que se localizam na superf?cie dos eritr?citos de diversas esp?cies. Em c?es, a infec??o pelos hemoplasmas pode causar anemia hemol?tica na fase aguda, enquanto na doen?a cr?nica os sinais em geral s?o inaparentes, sendo que a imunossupress?o pode desencadear a doen?a aguda. O presente estudo objetivou detectar molecularmente a presen?a de infec??o pelos agentes micoplasmas hemotr?ficos em c?es dom?sticos procedentes de ?reas urbana e rural de Aragua?na, Tocantins e, adicionalmente correlacionar as altera??es hematol?gicas e fatores associados com a infec??o natural. Na an?lise dos resultados obtidos, 2,9% (3/105) dos c?es amostrados da ?rea urbana e 24,49% (24/99) da ?rea rural foram positivos pela Rea??o em Cadeia da Polimerase em Tempo Real (qPCR) para Mycoplasma spp. A frequ?ncia de infec??o das esp?cies de hemoplasmas pela PCR, utilizando oligonucleot?deos esp?cie-espec?ficos, foi de 1,9 % (2/105) e 13,26% (13/99) para Mycoplasma haemocanis na ?rea urbana e rural, respectivamente. N?o foram observados c?es positivos para ?Candidatus Mycoplasma turicensis? e ?Candidatus Mycoplasma haematoparvum?/?Candidatus Mycoplasma haemominutum? em ambas as ?reas estudadas. No tocante ?s altera??es hematol?gicas, n?o houve associa??o estat?stica com a infec??o por Mycoplasma spp. De modo semelhante, dentre as vari?veis analisadas (idade, sexo, padr?o racial, limpeza do local e moradia) n?o foi verificada qualquer correla??o estat?stica com a infec??o pelo agente Mycoplasma spp., seja na ?rea urbana ou na rural. Esta constitui a primeira detec??o molecular de Mycoplasma haemocanis em c?es do Tocantins e abre perspectivas para futuros estudos neste grupo de agentes hemotr?ficos.

The aim of this study was to cany out phlebotominic fauna survey in ACL human cases occurrence areas. For sandfly collection monthly systematic captures by Castro trap from 6 o clock p.m. to 10 o clock p.m. for 12 months were performed. The diptera were placed on 70% alcohol bottles and carried to Sergio Arouca Public Health National School Biological Sciences Department Vectors Laboratory, Oswaldo Cruz Foundation, Rio de Janeiro, where they have been clarified and identified, as well. For dogs serology, blood samples from invaded residences animals as well as from a neighbour one, by venous puncture were taken. After serum centrifugation and separation, samples were stored at 20?C till serological assays performance at FIOCRUZ Public Health Nation School Immunodiagnosis Laboratory. The following methods: Indirect Immunofluorescence Reaction (IFIR) and Enzyme-linked immunosorbent assay (ELISA) were used. From October, 2004 to September, 2005, 2390 units from four species were captured. The predominant species was the Lutzomyia intermedia with 97.1% from total collected, followed by L. whitmani 1.6%, L.migonei 1.21% and L.oswaldoi 0.09 %. From 35 dogs serology: 60% (21) no reagent animals were reported, 22.9% just for ELISA, 2.9% for IFIR, and 14.2% (5) reagent animals for both techniques, definitely positive. No correlated evidences between serologies (IFIR+/ELISA+ and other results) in regard to animals residence (ill or neighbour) by Fisher statistical test were reported. It might be suggested that ACL transmission in Serop?dica County has basically been spread by Lutzomyia intermedia specie. The presence of reagent dogs unless suggestive injury may contribute for new ACL reports. / A Leishmaniose Tegumentar Americana (LTA) ? uma doen?a infecciosa n?o contagiosa causada por protozo?rios do g?nero Leishmania que acomete a pele e mucosa, sendo primariamente uma infec??o zoon?tica. O objetivo desta pesquisa foi realizar o levantamento da fauna flebotom?nica em ?reas com ocorr?ncia de casos humanos de LTA. Para coleta dos fleb?tomos foram realizadas capturas mensais sistem?ticas utilizando o capturador de Castro, no hor?rio das 18 ?s 22h, durante 12 meses. Os d?pteros foram colocados em frascos contendo ?lcool 70% e transportados para o laborat?rio de Vetores do Departamento de Ci?ncias Biol?gicas da Escola Nacional de Sa?de P?blica S?rgio Arouca, Funda??o Oswaldo Cruz, RJ, onde foram clarificados e identificados. Para sorologia dos c?es, amostras de sangue foram coletadas por venopun??o em animais residentes nos domic?lios acometidos e de c?es vizinhos. Ap?s centrifuga??o e separa??o do soro, as amostras foram conservadas a -20?C, at? o momento da realiza??o dos ensaios sorol?gicos no laborat?rio de Imudiagn?stico da ENSP, da FIOCRUZ. Empregaram-se os seguintes m?todos: Rea??o de Imunofluoresc?ncia Indireta (RIFI) e o enzyme-linked immunosorbent assay (ELISA). Foram capturados 2390 exemplares de flebotom?neos entre os meses de outubro de 2004 a setembro de 2005, pertencentes a quatro esp?cies. A esp?cie predominante foi a Lutzomyia intermedia com 97,1% do total coletado, seguida pela L. whitmani 1,6% , L.migonei 1,21% e L.oswaldoi 0,09 %. Da sorologia de 35 c?es: 60% (21) animais foram considerados n?o reativos; 22,9% reativos somente para ELISA; 2,9% somente RIFI e 14,2% (5) dos c?es reativos para as duas t?cnicas, conclusivamente positivos. N?o houve evid?ncias de associa??o entre sorologia (RIFI+/ELISA+ e outros resultados) com a propriedade do animal (paciente ou vizinho), segundo o teste exato de Fisher. Aparentemente a transmiss?o da LTA no munic?pio de Serop?dica esteja sendo veiculada pela L. intermedia. A presen?a de c?es reativos sem a exist?ncia de les?o sugestiva pode contribir para novos focos da LTA, funcionando como um animal em potencial para manuten??o da protozoose.
