For the diagnosis of 427 animals, serological (Enzyme-Linked Immunosorbent Assay, Indirect Immunofluorescence and/or Complement Fixation), parasitological and molecular (Polymerase Chain Reaction) tests were performed, which resulted in 117 (27.4%) confirmed positive cases. Of these, 96 (82.1%) were pure breed dogs and the others 21 (17.9%) were cross breed, being 57 (48.7%) females and 60 (51.3%) males. In terms of age, 26 (22.2%) were younger than 36 months, 48 (41%) were between 36 and 84 months, and 43 (36.8%) were older than seven years old. Sixty-four (54.7%) dogs were considered oligosymptomatic, 44 (37.6%) symptomatic, and the remaining nine (7.7%) asymptomatic. The main clinical findings were, in descending order, dermal lesions, lymphadenopathy, anemia, dysorexia, prostration and splenomegaly. As for hematological disorders, relative and absolute lymphopenia was the most important findings. Ninety-six (82.1%) of the positive animals correspond to allochthonus cases from São Paulo municipality.</span></p> | <!--[if gte mso 9]><xml> <o:OfficeDocumentSettings> <o:AllowPNG/> </o:OfficeDocumentSettings> </xml><![endif]--><p class="MsoNormal">Caracterizou-se retrospectivamente, a partir do ano de 1997 até março de 2008, a ocorrência de casos de leishmaniose, visceral ou tegumentar, dentre os cães dermatopatas atendidos em serviço especializado de hospital-escola veterinário de Faculdade de Medicina Veterinária e Zootecnia da Universidade de São Paulo. Para o diagnóstico em 427 animais, foram utilizados testes sorológicos (Ensaio Imunoenzimático Indireto, Imunofluorescência Indireta e/ou Fixação de Complemento), parasitológicos diretos e moleculares (Reação em Cadeia da Polimerase), que resultaram na confirmação de 117 (27,4%) casos positivos. Da amostragem, 96 (82,1%) eram cães de raça definida, os demais 21 (17,9%) não dispunham de plena definição racial, sendo 57 (48,7%) fêmeas e 60 (51,3%) machos. Quanto à faixa etária, 26 (22,2%) apresentavam idade inferior a 36 meses, 48 (41%) entre 36 e 84 meses e 43 (36,8%) ultrapassavam o sétimo ano de vida. Considerou-se 64 (54,7%) cães como oligossintomáticos, 44 (37,6%) sintomáticos e os nove (7,7%) remanescentes como assintomáticos. As principais alterações clínicas observadas foram, em ordem decrescente, lesões tegumentares, linfonodomegalia, anemia, disorexia, prostração e esplenomegalia. Quanto às alterações hematológicas, a mais importante foi a linfopenia relativa e absoluta. Dos animais positivos para a enfermidade, 96 (82,1%) correspondeu a casuística alóctone ao Município de São Paulo.</p><!--[if gte mso 9]><xml> <w:WordDocument> <w:View>Normal</w:View>

1999
Saulo Teixeira de Moura | Cláudia Gorgulho Nogueira Fernandes | Vanda Coutinho Pandolpho | Rosângela Rodrigues e Silva
Iniciou-se um estudo sobre a ocorrência de leishmaniose visceral e tegumentar em cães da área urbana de Cuiabá, Estado de Mato Grosso. No período de agosto de 1997 a julho de 1998, foram coletadas amostras de sangue de 800 cães, de diferentes bairros de Cuiabá, escolhidos aleatoriamente, e remetidos ao Serviço de Parasitologia do Instituto Municipal de Medicina Veterinária Jorge Vaitsman, no Rio de Janeiro, para exame pelo teste de imunofluorescência indireta. Foram processadas preliminarmente 62 amostras de soro, das quais 64,5% (40 amostras) estavam positivas para leishmaniose. Quanto às titulações encontradas nos soros reagentes, 92,5% (37 amostras) apresentaram títulos acima de 1:160, sugerindo forte suspeita da presença de leishmaniose visceral. Deste total, 72,5% (29 amostras) dos soros positivos são provenientes de cães da região Sul-Leste e 27,5% (11 amostras) da região Centro-Leste de Cuiabá. Este é o primeiro registro da detecção de cães sorologicamente positivos para leishmaniose em área urbana do Estado de Mato Grosso. | An investigation was carried out to determine the occurrence of cutaneous and visceral leishmaniasis in the urban canine population of the District of Cuiabá, State of Mato Grosso. In the period from August of 1997 to July of 1998 blood samples of 800 dogs were collected, from different neighborhoods of Cuiabá, chosen at random and sent to the Service of Parasitology of the Municipal Institute of Veterinary Medicine Jorge Vaitsman, in Rio de Janeiro, for examination by the indirect immunofluorescent test. At the beginning 62 serum samples were processed, from which 64.5% (40 samples) were positive for leishmaniasis. In relation to the titters found in the reacting serum, 92.5% (37 samples) presented titters above 1:160, what suggests strong suspicion of the presence of visceral leishmaniasis. From this total, 72.5% (29 samples) of the positive serum came from dogs of the South-East region and 27.5% (11 samples) of the Center-East region of Cuiabá. This is the first report of the detection of serum positive dogs for leishmaniasis in urban area of the State of Mato Grosso.
