RESUMO

ABSTRACT: This study discusses the causes of bird deaths recorded in a small aviary dedicated to the breeding of a few exotic, wild bird species. Findings from 28 birds were examined over a period of five years. About 40% of the deaths occurred in the first two weeks after hatching in the two most numerous species in the flock and such losses were mainly a result of starvation caused by inadequate nutritional management. Additionally, 28% of the cases affected recently introduced birds. Despite frequent treatment with anthelmintics; a total of 21% of the deaths in the flock could be attributed to parasitic diseases, most of them in recently acquired birds. Only three of the deaths could be associated with advanced age, all of the further cases were also attributable to management fails. Our results indicated that propagation of these and other species requires an improvement of the management of the newly hatched and newcomer birds to considerably enhance the flocks performance. Such information may be useful in conservation initiatives and may justify, at least in part, captivity of these animals.

RESUMO: Este estudo discute as causas de morte de aves registradas em um pequeno criadouro de umas poucas espécies de aves silvestres exóticas. As mortes de 28 aves foram examinadas em um período de cinco anos. Cerca de 40% dos casos ocorreram na primeira semana de vida de filhotes das duas espécies mais numerosas no plantel e essas perdas foram consequentes à desnutrição por falhas no manejo nutricional. Outros 28% de casos ocorreram em aves, recentemente introduzidas, ou em fase de adaptação, no criadouro. Ainda que as aves do plantel sejam frequentemente dosificadas com anti-helmínticos, 21% das mortes no plantel foram secundárias a doenças parasitárias; a maioria afetou aves recentemente adquiridas. Exceto por três mortes que foram associadas com desordens atribuídas à idade avançada, todas as demais foram associadas com inadequações no manejo das aves. Esses resultados sugerem que, em sistemas dessa natureza, as aves recém-nascidas e as recém-introduzidas são categorias críticas que demandam concentração de esforços para o atendimento sistemático de suas necessidades. Tais dados podem ser aplicáveis em iniciativas de conservação de outras espécies e podem justificar, ainda que parcialmente, a manutenção desses animais, em cativeiro.

RESUMO

Background: Rabies is a zoonotic disease caused by rabies virus, the genus Lyssavirus e family Rhabdoviridae. The commonest way of rabies transmission is by the bite of an infected mammal. Bites by rabid animals generally inoculate virus-laden saliva through the skin into muscle and subcutaneous tissues. Rabies has previously been regarded as 100% lethal. In South America, rabies in cattle is transmitted by vampire bats Desmodus rotundus mainly resulting in a major economic problem and public health. The present study retrospectively analyzed data from cattle affected by rabies registered between 2002 and 2007, evaluating the epidemiological, clinical and pathological and immunohistochemistry studies.Materials, Methods & Results: This retrospective study included epidemiological, clinical, pathological, direct immunofluorescence, and immunohistochemistry fi ndings from 26 cattle affected by rabies diagnosed by the Laboratory of Veterinary Pathology, UFRGS, Porto Alegre, RS, Brazil in the period from 2002 to 2007. The samples were selected from a histological diagnosis of lesions characteristic of rabies or positive direct immunofl uorescence for rabies where samples were available for histological examination. The central nervous system (CNS) samples of cattle were reported in 10% formalin fi xed, routinely processed for histology, embedded in paraffin, cut at 5 µm and stai

RESUMO

Background: Aspergillosis is the most common mycosis in birds, which are considered potential host also susceptible to the infection by Aspergillus spp. The clinical signs of the disease are often related to the respiratory tract, although other organs or systems may be affected. Signs are generally either not specifi c or may be directly related to the extent of the lesions in the respiratory tract (rhinitis, changes in the vocalization and dyspnea). The aim of this study was to describe and characterize three cases of aspergillosis in Greenwinged saltators (Saltator similis), based on reference standard diagnostics of this mycosis.Cases: Three Green-winged adult male saltators that had been participating weekly for three months in bird singing contests were referred to a private veterinary clinic. The clinical evaluation revealed pronounced hoarseness (3/3) and intense dyspnea (1/3). The animals were allocated to a warmed (280 C) oxygen chamber at 65% relative humidity. All birds were nebulized with saline solution and hyaluronidase. In addition, the birds were treated orally with complex vitamins B, A, D and E and intravenously either with dexamethasone and doxycycline (Case 1), azithromycin (Case 2) or metronidazole-enrofl oxacin combination (Case 3), in association with the use of Arnica Montana CH6 in the drinking water, and fl uid therapy (5% glucose, Ringer-lactate and

RESUMO

Difalo, penis duplo ou bifido e uma anomalia congenita rara que ocorre em animais e no homem, com escassos relatos na literatura. Este relato apresenta um caso de difalia em um bovino macho adulto castrado. A peca do sistema reprodutor de um bovino foi encaminhada por um frigorifico local para realizacao de exame histologico. O material foi analisado, fixado em formol 10%, processado de forma rotineira para histologia e corado pela hematoxilina-eosina. Macroscopicamente, a peca apresentava duas glandes penianas, uma composta pelo corpo cavernoso, corpo esponjoso, uretra e prepucio do penis, sugerindo que esta fosse a parte normal. Adjacente a essa, havia uma formacao tecidual identica a glande peniana, que, ao corte, no entanto, nao se observavam uretra, corpos cavernoso e esponjoso. Ao exame microscopico das duas glandes, confirmou-se sua estrutura histologica, uma composta por corpo cavernoso, corpo esponjoso e uretra e a outra somente de tecido conjuntivo fibroso revestido por epitelio. O diagnostico foi baseado nas alteracoes macroscopicas e constituicao histologica caracteristica. Esta anomalia pode prejudicar a miccao assim como o desempenho reprodutivo do animal.
