Leptospirosis is a zoonosis of worldwide distribution that has the dog as an important host, showing the importance of diagnosing and treating this animal that has a straight relationship with humans. A dog was attended at the Veterinary Hospital of the Federal University of Piauí in Teresina, Piauí, was present with history of hematuria, hyporexia and lethargy. Physical examination revealed lethargy, oral, ocular and penile icteric mucosa, pain at abdominal palpation and pyrexia. Hematologic analysis revealed hypochromic macrocytic anemia, thrombocytopenia, leukocytosis due to neutrophilia, and an increase in urea, AST, ALT, alkaline phosphatase and bilirubin values. The microscopic serum agglutination test showed a reactive result of Leptospira interrogans serovar Australis at the 1: 100 titre. The animal was effectively treated with Ampicillin, Doxycycline and supportive therapy.
RESUMO.A ocorrência de miosite dos músculos da mastigação é uma enfermidade relativamente esporádica na clínica de cães e gatos. No entanto, essa afecção acomete especialmente os cães de raças grandes e de meia-idade, todavia podendo surgir fora desses padrões. É característica da doença a dificuldade em abrir a boca, sialorréia, dispneia e de forma crônica a atrofia simétrica e bilateral dos músculos da face. Este relato tem por objetivo relatar o caso de um cão Sem Raça Definida, de 2 anos de idade, diagnosticado e tratado com droga imunossupressora, afim de promover a normalização do quadro do paciente. Palavras chave: Cães, miosite, músculos da faceMasticatory muscle myositis in undefined breed of domestic canine: Case report ABSTRACT: The occurrence of myositis of chew muscles is a relatively sporadic clinical disease in dogs and cats. However, this condition affects especially the large breed dogs and middle-aged, but may arise out of these patterns. The characteristic of disease is difficult to open the mouth, drooling, dyspnea and in a chronic form, symmetrical and bilateral atrophy of facial muscles. This report aims to report the case of a Mixed-breed dog, 2 years old, diagnosed and treated with immunosuppressive drugs in order to promote the normalization of the patient's condition.

La incidencia de miositis de los músculos de la masticación es una enfermedad relativamente esporádica en la clínica de perros y gatos. A pesar de la misma afectar especialmente los perros de razas grandes y de edad mediana, puede surgir fuera de esos estándares. Es característica de la patología la dificultad en abrir la boca, sialorrea, disnea y de forma crónica la atrofia simétrica y bilateral de los músculos de la cara. Este trabajo tiene por objetivo reportar el caso de un perro mestizo de 2 años de edad, diagnosticado y tratado con medicamentos inmunosupresores, a fin de promover la normalización del cuadro del paciente.Palabras clave: Perro, miositis, músculos de a cara
Leptospirosis is a worldwide zoonosis whose transmission is interlinked by multiple factors in the man-animal-ecosystem interface. This study aimed to evaluate the risk factors for the occurrence of anti-Leptospira antibodies in dogs in the capital Teresina (PI), and to determine their spatial distribution. Five hundred fifty-eight dog blood samples were submitted to the Microscopic Serum Agglutination (MSA) test. We applied semi-structured questionnaires to dog owners and obtained the area of residence for projection in geographical maps. Serum prevalence was 13.8%, in which the most common serovar was icterohaemorrhagiae, with 49.2%. Dogs with street access, failure to collect food bowl and low income of owners were risk factors. There was a higher number of seropositive dogs in the rainy season, with 87.1%, which is a probable risk factor for the occurrence of cases. The distribution of seropositive dogs was widely spread in the city, with predominance of cases in anthropized areas. These risk factors favor the occurrence of anti-Leptospira antibodies in dogs that are agent maintenance sources in the city and reinforce the need for epidemiological and environmental surveillance to prevent leptospirosis.
A possible explanation for the lower values after the addition of 50μM arachidonic acid would be its excessive concentration, considering that arachidonic acid, through the action of cyclooxygenase, is converted into prostaglandin E2, inducing the influx of Ca2+ through the membrane. sperm, leading to membrane fusion. It is concluded that the addition of 0.5μM and 5μM of arachidonic acid to the extender maintained the integrity of the acrosome membrane in post-cryopreservation goat semen, being beneficial for the process of sperm capacitation and fertilization, suggesting further research aiming at a greater accuracy of the concentrations of arachidonic acid as an antioxidant.
A leptospirose é uma zoonose mundial cuja transmissão está interligada por múltiplos fatores na interface homem-animal-ecossistema. Objetivou-se com este estudo avaliar os fatores de risco para a ocorrência de anticorpos antiLeptospira em cães na capital Teresina (PI), e determinar sua distribuição espacial. Amostras sanguíneas de 558 cães foram submetidas à prova de Soroaglutinação Microscópica (SAM). Aplicou-se questionários semiestruturados para os proprietários dos cães e obteve-se a localização geográfica da residência para a sua projeção em mapas geográficos. A soroprevalência foi de 13,8%, no qual o sorogrupo mais frequente foi o Icterohaemorrhagiae com 49,2%. Foram considerados fatores de risco os cães com acesso à rua, o não recolhimento da vasilha de alimento e a baixa renda dos proprietários. Foi observado maior número de cães soropositivos no período chuvoso com 87,1%, sendo um possível fator de risco para a ocorrência de casos. A distribuição dos cães soropositivos na cidade se apresentou de forma dispersa, com predominância dos casos em área antropizada. Esses fatores de risco favorecem a ocorrência de anticorpos antiLeptospiraem cães, os quais podem ser fontes de manutenção do agente na cidade e reforça a necessidade de vigilância epidemiológica e ambiental na prevenção da leptospirose.
