A leishmaniose visceral é uma enfermidade cujo agente etiológico no Brasil é o protozoário Leishmania infantum chagasi. Os cães são considerados reservatórios urbanos da doença, sendo indicadores da ocorrência de casos humanos. O presente trabalho teve como objetivo diagnosticar a infecção por L. infantum chagasi em cães domiciliados e errantes do município de Belém, estado do Pará, através da reação em cadeia da polimerase (PCR) e da reação de imunofluorescência indireta (RIFI), empregando dois antígenos distintos. Amostras de sangue venoso de cães adultos, sem distinção de sexo ou raça, de diferentes bairros e épocas do ano da cidade de Belém-PA, foram colhidas em tubos sem e com anticoagulante para obtenção do soro e do DNA, respectivamente. Esses animais foram divididos em dois grupos: cães errantes capturados pelo Centro de Controle de Zoonoses (Grupo A) e cães domiciliados (Grupo B). Os soros foram analisados através do teste de RIFI para pesquisa de IgG utilizando-se dois antígenos distintos: 1) antígeno do kit Bio-Manguinhos/FIOCRUZ (Ag-PRO) contendo formas promastigotas de Leishmania sp. (complexo major-like); 2) Antígeno do Instituto Evandro Chagas (Ag-AMA) constituído por formas amastigotas de L. infantum chagasi. A avaliação dos dois antígenos foi realizada com as amostras reagentes a partir da titulação 1:80. Já a PCR foi realizada a partir do DNA extraído do sangue total dos animais e amplificado utilizando-se os iniciadores RV1e RV2. Das 335 amostras analisadas, 10,4% (35/335) foram reagentes na RIFI (Ag-PRO) e 0,9% (3/335) reagiram com o Ag-AMA. A distribuição das amostras positivas se deu da seguinte forma: Grupo A 14,8% (25/169) com Ag-PRO e 1,2% (2/169) com Ag-AMA; Grupo B 6% (10/166) com Ag-PRO e 0,6% (1/166) com Ag-AMA; sendo que todas as amostras positivas pelo teste de RIFI com o Ag-AMA também reagiram com o Ag-PRO e em nenhuma das amostras foi detectado o DNA de L. infantum chagasi. Os achados do presente estudo indicam que Belém ainda pode ser considerada área não endêmica para leishmaniose visceral canina e que a natureza do antígeno influencia no resultado da RIFI para a pesquisa de anticorpos anti-L. infantum chagasi em cães, sendo que a RIFI que utiliza formas promastigotas de Leishmania major-like como antígeno deve ser utilizada com cautela como método diagnóstico confirmatório em estudos epidemiológicos em áreas não endêmicas para LVC.

The atlantoaxial subluxation or luxation is an instability of this articulation that produces excessive flexion of this joint causing the cranial aspect of the axis to rotate dorsally into the vertebral channel with subsequent spinal cord compression. This disorder is most commonly found in young small breed dogs. The diagnosis of this disease is done by survey radiographs, where there is a larger distance between the atlas dorsal arch and the axis spinal process characterize the atlantoaxial subluxation. Surgical stabilization is the treatment of choice and multiple implants show the best results to stabilize the atlantoaxial joint. The main complications are sudden death or implant failure. The sudden death happens because of cardiorespiratory arrest and it is most likely caused by brainstem iatrogenic trauma. However, a larger study comparing different surgical stabilization techniques should be performed to evaluate relative success rates in dogs that have the same initial neurologic status

Pancreatitis is a predominantly disease of the exocrine pancreas, which occurs commonly in dogs. Acute pandreatitis is reversible, with the removal of the primary cause, whereas chronic pancreatitits is irreversible, with histopathological changes, such as atrophy and fibosis that occurs from persistent inflammation. In dogs, clinicl signs ranging among abdominal pain and anorexia until potential insufficiency of various organs and Disseminated Intravascular Coagulation. In general, dogs with acute illness presents vomiting, anorexia, abdominal pain and several degrees of dehydration, collapse and shock. The caim of this monograph is evaluate ultrassound changes in dogs with panceatitis. Ultrassound is a valuable technique to evaluate exocrine pancreas, with association with another diagnostic modalities will be able to increase the preciosion of the diagnosis

The purpose of this work was to provide guidance to householders in the responsible care of their pets, in a region where canine visceral leishmaniasis is endemic. Questionnaires on responsible ownership and the control of this disease were completed by owners of dogs and cats in the city of Araçatuba, São Paulo State, Brazil, in order to evaluate their level of knowledge. Based on the identified deficiencies, the project team provided the owners of the pets with individual guidance at home, focusing on the most critical issues. Concerning nutrition, 70.45% (62/88) of owners provided pet food only, 27.28% (24/88) administered a mixed diet, and 2.27% (2/88) provided homemade food. Additionally, 78.41% (69/88) did not permit the consumption of raw meat, rare meat, or bones. 9.09% (8/88) of owners allowed their pets to wander the neighborhood alone. Among dogs, 14.77% (13/88) had never been clinically tested by a qualified professional, and 6.82% (6/88) and 15.91% (14/88) had never received any kind of vaccine or vermifuge, respectively. In relation to population control, only 20.45% (18/88) of the dogs had been sterilized. It was also observed that 25% (22/88) of owners had already had canine visceral leishmaniasis seropositive dogs in their homes. 54.55% (12/22) of these owners had referred their pets to veterinary clinics for euthanasia, 22.73% (5/22) had used the services of the city’s animal disease control center, and 18.18% (4/22) had paid for private treatment. Nevertheless, 35.23% (31/88) of the dogs had never been submitted to tests for infection diagnosis. From the results obtained, it could be inferred that the individuals who participated in this study were poorly informed concerning basic pet care, demonstrating a need to implement community awareness campaigns for the responsible ownership of pets.

Canine Distemper is a contagious, severe and multisystemic disease caused by a virus from Morbillivírus genus. The virus is distributed worldwide and it presents a high lethality rate, affecting mainly dogs. The diagnosis is based on clinical signs associated with hematological fi ndings. The observation of Lentz bodies in erythrocytes and leukocytes is the defi nitive diagnosis for the disease. The aim of this work was to test the hypothesis that the hematological profi le in dogs positive for canine distemper differs according to blood cell type presenting Lentz bodies. For this purpose, 25 dogs positive for the disease were evaluated at the Veterinary Hospital “Luís Quintiliano de Oliveira” UNESP, Araçatuba city. The diagnosis was based on the observation of Lentz bodies in blood smears. Fromthe total, 64% of dogs presented anemia, 16% leucopenia and 12% leukocytosis. Lymphopenia occurred in 76% of dogs. Viral inclusions were observed solely in neutrophils (32%), lymphocytes (28%) and erythrocytes (12%). Concomitant observation occurred in lymphocytes and erythrocytes (4 %), in lymphocytes and neutrophils (12%), in neutrophils and monocytes (4%) and in neutrophils and erythrocytes (4%). In an isolated case Lentz bodies were observed simultaneously in neuthrophils, monocytes and lymphocytes. In conclusion, hematological profi le is not associated with the presence of viral inclusion in a particular cell type.

O presente relato tem por objetivo descrever o primeiro caso alóctone de leishmaniose visceral (LV) no município de Campo Mourão, Paraná, Brasil, em um canino, da raça Boxer, apresentando lesões oculares e cutâneas, linfoadenomegalia e esplenomegalia, atendido no Hospital Veterinário da Faculdade Integrado de Campo Mourão, após ter residido na cidade de Campo Grande, Mato Grosso do Sul. O diagnóstico da enfermidade baseou-se na observação direta de formas amastigotas de Leishmania spp., em linfonodos poplíteos, sugerindo ser um caso de LV, uma vez que o animal era proveniente de área endêmica para a enfermidade. A migração de cães infectados de regiões endêmicas para áreas indenes torna-se um problema para a saúde pública, uma vez que poderá permitir a instalação de novos focos, favorecendo a disseminação da doença em todo o país.
