Toxoplasmosis is a zoonotic disease caused by Toxoplasma gondii. Most often, the disease is asymptomatic in dogs due to effectiveness of the immune system. By the way, numerous clinical signs can be triggered, including neuromuscular like ataxia, circling, behavioral changes, seizures, spasms and tremors. The disease usually manifests itself after immune depression, and, for this reason, usually may be associated to immunosuppressive infections, like by distemper virus and Ehrlichia canis. E. canis is an obligatory intracellular rickettsia of mature or immature hematopoietic cells and canine monocytes, and the etiologic agent of Canine Monocytic Ehrlichiosis (CME). Like toxoplasmosis, CME may cause nervous signs as well. This study aims to estimate the occurrence of anti- T. gondii and anti- E. canis antibodies and characterize nervous syndromes in dogs with nervous alterations assisted at a veterinary teaching hospital. From May 2010 to December 2011, dogs with nervous alterations assisted at HOVET-UFMT were submitted to neurological evaluation for determining nervous syndromes. Serum and whole blood samples were collected for performing indirect immunofluorescence test (IFAT) for T. gondii and E. canis and hematological evaluation. Prevalence of 10,3 and 94,8% were observed for T. gondii and E. canis, respectively. The most frequent syndrome was multifocal, occurring in 53,5% of the cases, followed by spinal cord alterations in 22,4%, cerebral alterations in 10,3%, paroxysmal syndrome in 10,3% and neuropathic syndrome in 3,5% of the cases. There was no statistical significance between the variables analyzed (titration to T. gondii, E. canis and nervous syndromes). In conclusion, the occurrence of coinfection with T. gondii and E. canis may contribute to toxoplasmosis clinical manifestation, due to opportunist character of the parasite in order to the establishment of disease.

Radiographic evaluation of the cardiac silluet using the VHS method (Vertebral Heart Size) in young and adults coatis (Nasua nasua, Linneaus 1766) living in captivity [Avaliação radiográfica da silhueta cardíaca, pelo método VHS (Vertebral Heart Size), de quatis (Nasua nasua, Linnaeus 1766) jovens e adultos mantidos em cativeiro]

Radiographic examination of the toracic cavity is an usefull noninvasive method for assessment, monitoring the progress of heart disease, suggesting prognosis and guiding the treatment. The aim of this study was to evaluate the cardiac silhouette of young and adults coatis and evaluate its relationship to the number of thoracic vertebrae (VHS), the method proposed by Buchanam and Buchele (1995) for small animals. We evaluated a group of 20 coatis, divided by age: I (GI) and 8 animals aged between 4 and 5 months and group II (GII) with 12 animals over 12 months old. Based in chest radiographs and VD laterolateral right projections for determining the major axis (L) and short axis (Y) being the sum of L and S is the value obtained by ESR, the relative depth/width (D / L) chest were obtained and the results determined the type of conformation of the thorax, which results greater than 1.25 cm denote chest type deep, 0.75 to 1.25 cm chest intermediate and inferior results will 0.75cm wide chest. It was observed that the heart is alocated between the fourth and seventh pair of ribs, VHS average coatis healthy adults was 9.36 ± 0.75 and 8.06 ± 0 youth, 595 units thoracic vertebrae and the predominant conformation found was of intermediate type when compared to dogs. The mean values in this study serve as a basis for interpretation of the VHS type, however, a larger number may be required animals to determine the physiological limits of the cardiac silhouette in coati.
