RESUMO

This paper reports the clinical, bacteriological and pathological findings of a thoracic aortic aneurysm in a four-year-old Anglo-Nubian goat buck, related to a framework of visceral caseous lymphadenitis. General clinical examination showed heart rate of 75 beats per minute, respiratory rate of 20 movements per minute and ruminal movements of four movements per minute. Superficial lymph nodes were normal upon palpation. Rectal temperature was slightly high (40.5°C). Blood test showed an intense leukocytosis (54,000/µL), characterized by strong neutrophil shift to the left. At necropsy, a large blood clot was detected in the thoracic cavity. The thickening of the myocardium and dilatation of the aorta in the thoracic portion, presenting a saculiform format was also observed. A large number of abscesses were disseminated in the media and intima layers of aorta. The aorta lumen obstruction by arterial plaques consisting of inflammatory infiltrate, predominantly neutrophilic was also detected. Abscesses were found spread in turbinate, rumen, reticulum, kidneys, liver, spleen, testicles and aorta wall. The microbiological exam of exudate confirmed Corynebacterium pseudotuberculosis as the causal agent.

Este trabalho descreve os achados clínicos, bacteriológicos e patológicos de um aneurisma da aorta torácica em um reprodutor caprino da raça Anglo-Nubiana, de quatro anos de idade, relacionado a um caso de linfadenite caseosa visceral. Ao exame clínico geral observaram-se: frequência cardíaca de 75 batimentos por minuto, frequência respiratória de 20 movimentos por minuto e movimentos ruminais de quatro movimentos por minuto. Os linfonodos superficiais encontravam-se normais à palpação. A temperatura retal estava ligeiramente aumentada (40,5°C). No hemograma completo, observou-se leucocitose intensa, 54.000/µL, caracterizada por um forte desvio neutrofílico à direita. Nos achados de necropsia, observou-se, na cavidade torácica, presença de um grande coágulo de sangue. No coração, foi identificado espessamento do miocárdio. Uma dilatação na porção torácica da artéria aorta foi detectada, apresentando um aspecto saculiforme. Um grande número de abscessos estava presente nas camadas média e íntima da aorta. Observou-se, também, obstrução do lúmen da aorta por placas de infiltrado inflamatório, predominantemente neutrofílico. A disseminação de abscessos nos cornetos, rúmen, retículo, fígado, baço, rins, testículos e parede da aorta foi detectada. O exame microbiológico do exsudato confirmou o Corynebacterium pseudotuberculosis como o agente causal.

RESUMO

Quando o homem começou a domesticar os animais e colocá-los em cativeiro, sua principal preocupação restringia-se a como impedi-los de escapar e como poderiam ser mantidos vivos e saudáveis. Mais tarde, começaram a se preocupar com a produção, sobretudo de leite e carne, o que exigia aumentar o número de crias. Durante esses tempos, os distúrbios advindos do estresse eram problemas, apenas, na medida em que eles afetavam a saúde e o desempenho do animal. O conceito de estresse só foi desenvolvido ao longo de várias décadas, por volta da metade do século 20, dando origem ao modelo atual em foco. Este sugere que a homeostase, ou seja, estabilidade por meio de mudanças, as quais acarretam alterações no metabolismo do corpo, ajuda o animal a antecipar novos desafios e, assim, responder a eles, contribuindo, dessa forma, para uma melhor adaptação ao seu ambiente. O estresse é responsável por alterações no metabolismo e, em consequência, no funcionamento dos diferentes sistemas, entre eles o reprodutivo. Estudos sobre o estresse nos animais domésticos, em especial bovinos, ovinos e suínos, são abundantes, pois eles representam grande parte da alimentação consumida no globo terrestre. Em caprinos, no entanto, esses estudos ainda são escassos, provavelmente, em virtude de sua pouca expressão no mercado global de carne e leite. Esta revisão visa mostrar os tipos de estresse mais estudados no caprino macho e sua interferência na função reprodutiva. (AU)

When man began to keep animals in captivity, his main concern was restricted to prevent them from escaping, and how they could be kept alive and healthy. Later they began to be concern about the production, focusing on producing more milk and meat and, therefore, increase the number of offspring. During these times, the disturbances arising from stress were problems only if they affect the health and animals performance. The concept of stress has only been developed over several decades, by the mid-20th century, giving rise to the current model in focus, in which suggests that homeostasis, which means stability through change, causing changes in the functioning of the body, help the animal to anticipate new challenges and thus respond to them, thus contributing to a better adaptation to their environment. The stress is responsible for alterations in body metabolism and, therefore, the function of the different systems, including among them the reproduction. Studies on stress in domestic animals, especially cattle, sheep and pigs are plentiful, as they represent most of the food consumed on the globe. In goats, however, these studies are still scarce, probably because of its low expression in the global market of meat and milk. This review aims to show the types of stress most studied in male goats and their interference on reproductive function.(AU)

RESUMO

The lack of information about seasonal variation of seminal plasma proteins in goats from Northeast Brazil led us to investigate the protein band distribution throughout the year. The experiment lasted one year (from April 2006 to March 2007) in which 230 semen collections from five adult goats (Capra hircus) were carried out, at ages ranging from 18 to 22 months, weighing 42.0 ± 10.0 kg, belonging to Anglo Nubian breed. A pool of seminal plasma samples from all the animals in each month of the year was submitted to 1D electrophoresis SDS-PAGE, 12.5%. The gels were analyzed through Life Science Software from UVP, Inc®. The correlation between air humidity and total seminal plasma proteins was not significant (r = -0.24; P > 0.05), while a moderate and significant correlation was found between temperature and total protein (r = 0.39; P < 0.001). The semen volume and concentration showed statistical difference (P < 0.05) between months throughout the year, while the motility and vigor did not (P > 0.05). The analyzed gels showed a high frequency of molecular mass bands below 50 kDa throughout the year, followed by protein bands from 50 to 100 kDa. The major numbers of bands occurred in October and November, while May was the month that presented a smaller number of protein bands. The molecular bands of 14, 22, 24, 40, 55 and 66 kDa were present in all the months of the year. The band of 16 kDa was found in 41.7% of the months. May was the only month that did not show the 30 kDa. August and September did not present the bands of 34 and 35 kDa, while October showed both bands. The 45 kDa band was found in 75% of the months, being present in January, May, July, September and November. The 46 kDa band was identified in June and August, while the 47 kDa was identified in April. The 70 kDa band was identified from May to November (58.3%), the 72 kDa band was found in January, March and April (25%) and bands of 92 to 97 kDa were found from April to December (75%). These results showed a band distribution variation throughout the year in the Anglo Nubian goat breed in the semi-arid area of Brazil. It is concluded that medium rainfall or water scarcity in the dryer months seems to promote variation in semen volume and concentration and total protein distribution throughout the year. As no month variation was observed in semen motility and vigor, and protein bands probably related to fertility showed an uniform distribution throughout the year, it is suggested that there is no fertility variation during the year in anglo-Nubian goats the semi-arid region.(AU)
