ABSTRACT
Proliferative arteritis of the canine nasal philtrum is an unusual disease with an unknown etiology and very few cases described in literature to date. Two patients with characteristic lesions underwent biopsy and confirmation by histopathological assessment. The first case was treated with oral prednisolone once daily and topical tacrolimus twice daily. The second case was treated twice daily with pentoxifylline and topical tacrolimus. Both treatments were successfully used by other authors previously. In result, clinical improvement varied among patients. The lesion of the first case showed no clinical improvement after 15 days of treatment. The second case showed a mild improvement of the initial lesion. In conclusion, treatment with tracolimus, pentoxifylline, and prednisonole appears to have a good effect in mild and early lesions. The objective of this paper was to describe the clinical findings, treatment options and histopathological aspects in two Brazilian Mastiff dogs, not previously reported.

São descritos dois casos de parasitismo por Cruorifilaria tuberocauda em capivaras de vida livre no Distrito Federal, Brasil. Macroscopicamente, observou-se nas superfícies de corte dos rins espessamento acentuado de vasos das regiões cortical e córtico-medular. Microscopicamente, havia arterite proliferativa e granulomatosa acentuada associada a filarídeos intralesionais consistentes com Cruorifilaria tuberocauda. Esse é o primeiro relato do parasitismo por esse filarídeo em capivaras no Distrito Federal.
This report describes two cases of parasitism by Cruorifilaria tuberocauda in wild capybaras (Hydrochoerus hydrochaeris) from Distrito Federal, Brazil. Grossly, there was marked thickening of vessels wall of the cortical and corticomedullary regions of both kidneys. Microscopically, there was severe proliferative and granulomatous arteritis associated with intralesional filarids, consistent with Cruorifilaria tuberocauda. For the first time this filarid is reported parasitizing capybaras in Distrito Federal, Brazil.

Infections by equine herpesvirus (EHV) and equine arteritis virus (EAV) have been associated with important economic losses for the equine industry worldwide. Serological studies have indicated the presence of these agents in Brazil. The aim of this study was to evaluate the occurrence of specific antibodies against EAV and EHV in horse herds from different regions of Rio de Janeiro state. For this purpose, serum samples of 581 non-vaccinated animals and 44 breeding mares regularly vaccinated against equine rhinopneumonitis were collected. All samples were submitted to the virus neutralization test for the detection of specific antibodies to each virus. Results showed 29.6% (172/581) of seropositive animals for EHV (titers between 2 and ? 256) and 0.79% (5/630) for EAV (titers between 2 and 4,096). Considering the non-vaccinated animals, these findings demonstrated that specific antibodies were induced after natural exposure to the respective viruses, suggesting a probable circulation of these agents in the studied herds.
A infecção pelo herpesvírus equino (EHV) e o vírus da arterite equina (EAV) tem sido associada a perdas econômicas importantes para a equideocultura em nível mundial. Estudos sorológicos têm demonstrado a circulação destes agentes no Brasil. O presente trabalho teve como objetivo principal estudar a ocorrência de anticorpos específicos contra o EAV e EHV em cavalos oriundos de diferentes regiões do estado do Rio de Janeiro. Para este propósito, foram coletadas amostras de soro de 581 animais não vacinados e de 44 éguas provenientes de um plantel vacinado regularmente contra a rinopneunonite equina. Todas as amostras foram submetidas ao teste de soroneutralização para a pesquisa de anticorpos específicos contra cada um dos vírus. Os resultados demonstraram 29,6% (172/581) de animais soropositivos para o EHV (títulos entre 2 e ? 256) e 0,79% (05/630) para o EAV (títulos entre 2 e 4.096). Considerando a sorologia positiva em animais não imunizados, os achados demonstram a indução de anticorpos específicos após exposição natural aos respectivos vírus, indicando uma possível circulação desses agentes nos rebanhos analisados.
