Parasitic infections, hematological and biochemical parameters suggest appropriate health status of wild coati populations in anthropic Atlantic Forest remnants.

Coatis are hosts of a great diversity of parasites, that due to anthropic pressures in forest fragments, like changes in landscapes and ecosystems, can influence the dynamics and physiological responses to those parasite infections, affecting the animal's health and fitness. This is the first study about health parameters and parasitic infections of wild coati (Nasua nasua) populations in the Atlantic Forest (Pernambuco Center of Endemism). The following hypotheses were evaluated: (i) infections and co-infections by gastrointestinal parasites and ectoparasites can generate changes in the health parameters of coatis such as the body condition score (BCS), packed cell volume (PCV), leukogram, and serum protein profile; (ii) biological aspects (sex and age) or fragment they inhabit, can influence changes in the health parameters (BCS, PCV, leukogram and serum protein profile). Were studied 55 free-living coatis in three anthropized forest remnants in the Metropolitan Region of Recife. After chemical containment, the animals were submitted to physical examination and collection of biological samples (blood, feces, and ectoparasites). On the physical examination, 23.6% of coatis had a low BCS and 5.4% were overweighted. Amblyomma spp. ticks were found in 83.6% of the animals of all studied remnants, A. sculptumAmblyomma sculptum in 12.7% and A. ovale in 1.8%. Regarding gastrointestinal parasites, Ancylostoma sp. was the most prevalent (80.4%) and most animals (66.7%) had co-infection with Ancylostoma sp. and Capillaria sp., Strongyloides sp., Acanthocephala, Cestoda, and Coccidia. The 76.5% of the coatis presented co-infections with Ancylostoma spp. + Amblyomma spp. Principal coordinates analyses (PCoA) scores of health parameters were used as dependent variables and fragment, sex, age, Ancylostoma sp. infection, gastrointestinal parasites co-infection, Amblyomma spp. infestation and co-infection of Ancylostoma sp. + Amblyomma spp. as a predictor variable in the linear models. Parasites did not influence the PCV of the individuals, but a decrease was evident in adult animals. Variations in protein profile, neutrophils, and lymphocytes, without leaving the normal range for the species, but WBC were predicted by age group, and infections by Ancylostoma or Amblyomma spp., but not their co-infections. The free-living coati populations of the anthropized remnants in the Atlantic Forest of northeastern Brazil proved to be healthy and seem to be adapted to face the challenges of anthropization and parasitic infections.

Mielografia de cães sadios com o meio de contraste ioversol: resultados liquóricos e anatomo-histopatológicos / Myelography in normal dogs with ioversol contrast medium: cerebrospinal fluid and anatomohistopathological results

O meio de contraste ioversol 240mg de iodo(I) por ml foi administrado na dose de 0,5ml/kg de peso por via intracisternal em 30 cäes sadios, com o objetivo de verificar as possíveis alteraçöes liquóricas e histopatológicas geradas pelo mesmo. Foram realizadas no líquor, análises físicas, contagens total e diferencial de leucócitos e determinaçäo da concentraçäo total de proteínas. A análise do líquor pós-mielográfica revelou aumento no número de leucócitos totais em três animais e da concentraçäo de proteína em quatro. Alteraçöes histopatológicas foram observadas em dois deles: infiltrado de células inflamatórias mononucleares na fissura ventral e no canal central da medula espinhal e infiltrado discreto de células inflamatórias mononucleares no canal central da medula espinhal, respectivamente. Concluiu-se que a mielografia com o meio de contraste ioversol 240mg I/m img src= align="absmiddle" pode causar alteraçöes citológicas e na concentraçäo de proteínas no líquor, e histopatológicas, porém discretas, durante o período estudado

Aspectos epidemiológicos e clínicos da intoxicaçäo por Pithomyces chartarum em ovinos da raça Santa Inês, no município de Gravatá - PE / Epidemiological and clinical aspects of Pithomyces chartarum intoxication in Santa Inês ovine in Gravatá City - PE

Registra-se ocorrência de intoxicaçäo por Pithomyces chartarum em ovinos da raça Santa Inês, em pastagem de Brachiaria decumbens, no município de Gravatá-PE, com os seguintes achados clínico-patológicos: anorexia, apatia, icterícia, edema palpebral e de orelhas, opacidade de córnea, exsudaçäo purulenta ocular, dermatite na face interna da orelha, febre, desidrataçäo; fígado aumentado e sensível, reduçäo do tempo de coagulaçäo, decúbito e morte; anemia normocítica e hipocrômica, inversäo na relaçäo neutrófilo-linfócito, aumento de Aspartato Amino-Transferase, Gama GT, elevaçäo das Bilirrubinas Total, Direta e Indireta, além de hemoglobinúria. A necrópsia observou-se icterícia generalizada, fígado amarelado e aumentado; congestäo intestinal; baço discretamente aumentado e congesto. Conídeos do fungo P. chartarum foram identificados na pastagem e cujas toxinas foram responsáveis pelas lesöes de fotossensibilizaçäo hepatógena em ovinos com pelagem e pêlos pretos.
