Alterações clínicas, laboratoriais e seminais de cães naturalmente infectados por Leishmania sp / Clinical, laboratory and seminal changes of dogs naturally infected by Leishmania sp

A Leishmaniose Visceral (LV) é uma doença parasitária crônica, grave e endêmica em algumas regiões do Brasil, tendo os humanos e os cães como principais hospedeiros. Objetivou-se com este trabalho avaliar o perfil clínico, laboratorial e seminal de cães machos Sem Raça Definida (SRD) diagnosticados com LV, no município de Teresina, Piauí. Os animais foram provenientes da Gerência de Controle de Zoonoses do município e levados para o canil do Centro de Ciências Agrárias da Universidade Federal do Piauí, onde permaneceram de fevereiro a abril de 2014 sob avaliação e realização de exames. Foram coletadas amostras de sangue e sêmen de 12 cães, divididos em dois grupos, sendo 06 positivos (GI) e 06 negativos (GII) para a doença. Os resultados apontaram linfadenomegalia, emagrecimento e onicogrifose como principais sinais clínicos nos cães com LV e as alterações hematológicas foram, anemia normocítica normocrômica e trombocitopenia. A análise de bioquímica sérica revelou aumento nos índices de ureia nos animais parasitados no final do experimento, com diferença estatística entre os grupos, porém os níveis de creatinina mantiveram-se sem alteração. Quanto às análises seminais, foram encontradas diferenças significativas entre os grupos nos parâmetros de motilidade, vigor e concentração espermática, além da presença de patologias espermáticas que indicaram aumento de espermatozoides com alterações de cabeça e cauda. Conclui-se que cães com LV apresentam alterações clínicas, laboratoriais e seminais que podem prejudicar a condição geral e reprodutiva dessa espécie animal.

The Visceral Leishmaniasis (VL) is a chronic and severe parasitic disease, endemic in some regions of Brazil, and having dogs and humans as the main hosts. The objective of this work was to evaluate the clinical, laboratory and seminal profile of Mixed breed male dogs diagnosed with VL, in the city of Teresina, Piauí. The animals were obta ined from the Zoonoses Control Management of city and taken to the kennel of the Agrarian Sciences Center of the Federal University of Piauí, where they remained from February to April 2014 under evaluation and exams. Blood and semen samples were collected from 12 dogs, divided into two groups, being 06 positive (GI) and 06 negative (GII) for the disease. The results indicated lymphadenomegaly, weight loss and onychogryphosis as the main clinical signs in dogs with VL and the hematological changes were normochromic normocytic anemia and thrombocytopenia. The analysis of serum biochemistry revealed an increase in urea indexes in the parasitized animals at the end of the experiment, with statistical difference between the groups, however the levels of creatinine remained unchanged. Regarding the seminal analyzes, significant differences were found between the groups in the parameters of motility, vigor and sperm concentration, in addition to the presence of sperm pathologies that indicated an increase in sperm with changes of the head and tail. It is concluded that dogs with VL present clinical, laboratory and seminal alterations that can impair the general and reproductive condition of this animal species.

Ocular diseases in dogs naturally affected by visceral leishmaniasis in Teresina, Piauí, Brazil / Oftalmopatias em cães naturalmente acometidos por leishmaniose visceral em Teresina, PI, Brasil

This study aimed to characterize ocular diseases in dogs naturally affected by visceral leishmaniasis in Teresina, Piauí State, Brazil. The diagnosis was made using parasitological exams of the bone-marrow and lymph-node samples. The main ophthalmological findings were uveitis, conjunctivitis, blepharitis, keratitis, and keratoconjunctivitis sicca. Normocytic normochromic anemia was the main hematological finding, followed by thrombocytopenia. Plasma proteins were also considered, and hyperproteinemia, hypergammaglobulinemia, and hypoalbuminemia were observed. Ocular histopathological examination revealed mild inflammation involving lymphocytes, monocytes, and macrophages. Results indicate the need to perform a differential diagnosis to rule out or establish the presence of Leishmania sp. in dogs presenting with ophthalmic lesions in endemic regions.

O presente trabalho teve por objetivo caracterizar as oftalmopatias em cães naturalmente afetados por leishmaniose visceral em Teresina, Piauí. O diagnóstico de leishmaniose foi realizado por exame parasitológico de medula óssea e linfonodos. As principais alterações oftálmicas foram uveíte, conjuntivite, blefarite, ceratite e ceratoconjuntivite seca. Anemia normocítica normocrômica foi a principal alteração hematológica, seguida de trombocitopenia. Em relação às proteínas plasmáticas observou-se hiperproteinemia, hiperglobulinemia e hipoalbuminemia. A histopatologia ocular revelou processo inflamatório moderado constituído por linfócitos, monócitos, neutrófilos e macrófagos. Os resultados da pesquisa apontam para a necessidade de se realizar diagnóstico diferencial para Leishmania sp. em cães que apresentem lesões oftálmicas em regiões endêmicas.

Epidemiology and anesthetic risk in dogs with aural hematoma / Epidemiologia e risco anestésico de cães portadores de otohematoma

Background: Otohematoma or aural hematoma in dogs is blood pooling within the ear cartilage plate, and stems from several causes (ear infections, ectoparasites and others). The formation of hematoma is by vascular injury, causing bleeding, generated by self-injury. This disease occurs especially in dogs of pendulous ears, and the concave surface of the ear is considered as the most frequent. The therapy to correct the lesion can be a clinical procedure; however, surgical drainage is the treatment of choice. This work aims to record the epidemiological aspects related to aural hematoma in dogs, as well as classify such patients as to the physical condition and anesthetic risk. Materials, Methods & Results: Twenty five dogs with aural hematoma submitted to surgical procedure were followed. During the data collection period (seven months), surgery to correct aural hematoma represented 19% of surgeries performed in dogs (total of surgeries: 474). The percentage of canine breeds affected was: mixed breed (64%; 16/25), german shepherd (24%; 6/25), labrador (4%; 1/25), waimaraner (4%; 1/25) and daschund (4%; 1/25). Most occurrences were observed in females aged 3-12 years. Most of the animals showed only one pina affected (96%; 24/25), and 52% (13/25) had hematoma in the right and 44% (11/25) in the left ear. Some of the patients had no hematologic abnormalities (48%; 12/25) [...](AU)
