Palma-Irizarry, M., Damian-Matsumura, P., Betancourt, M., Romo, S., Perales, G., Lagunas-Martínez, A., Madrid-Marina, M. V., Mejía, O. and Ducolomb, Y. 2012. Identification of novel variants of interferon-tau gene in Bighorn sheep ( Ovis canadensis mexicana ), Pelibuey sheep ( Ovis aries ) and its expression in hybrid blastocysts ( Ovis canadensis×Ovis aries ). Can. J. Anim. Sci. 92: 275–283. The major signal for maternal recognition of pregnancy (MRP) in ruminants is interferon-tau (IFNT). Four novel sequences of the IFNT gene were isolated from genomic DNA obtained from blood samples of Bighorn, Pelibuey or the hybrid ewes. The deduced amino acid sequence of the hybrid ewe showed 100% identity with one Bighorn sheep IFNT sequence, suggesting that this sequence was inherited from Bighorn sheep. The high degree of identity between Pelibuey and Bighorn sheep sequences could be a possible explanation for the successful MRP in some Bighorn hybrid pregnancies. In vivo and in vitro domestic sheep (Ovis aries) and hybrid sheep (Ovis aries×Ovis canadensis) blastocysts were obtained, and IFNT expression was measured by semiquantitative RT-PCR. In vivo and in vitro hybrid blastocysts showed lower expression of IFNT when compared with domestic blastocysts. In conclusion this study showed that there exists an effect of hybridization on IFNT expression and this can affect the MRP.

Abstract:

Abstract Introduction: The palatine tonsil play a key role in initiating immune responses against the antigenic material entering the mouth. Materials and Methods: Tissue pieces of oropharynx for the palatine tonsilwere collected from different prenatal age groups of sheep. These tissue pieces were fixed and processed for routine paraffin embedding technique to get 3-5pm thick sections. The paraffin sections were subjected to routine haematoxylin and eosin and some other special staining methods. Results: In three months foetal age of sheep, the palatine tonsils appeared as diffused lymphocytic infiltration in the propria submucosa overlaid by the mucosa of the oropharynx. The surface epithelium of the mucosa of the oropharynx formed primary crypts. The primary crypts in turn invaginated to form secondary crypts. The collagen fibres from the submucosa appeared to enter at the base of the developing tonsil. In the fourth month of foetus, the tonsillar surface epithelium became thicker and many crypts arose from that of primary crypts. Organized lymphocytic infiltration as isolated units was noticed near or around the secondary crypts. In five months of foetal age, the crypt epithelium was found to be infiltrated with lymphocytes, macrophages, plasma cells and mesenchymal cells. The connective tissue capsule and septa were completely formed. The lymphocytic tissue was characterized by an increased population of lymphocytes in the primary follicles without germinal centres. Conclusion: The results were compared with the literature and the palatine tonsil showed the gradual changes of histoarchitecture from third to fifth month of foetal age.

Abstract:

RESUMO Esta pesquisa visou estabelecer valores de referência para a interpretação da reação tuberculínica em ovinos experimentalmente inoculados com cepas padrões de Mycobacterium bovis AN5 e Mycobacterium avium D4, além de avaliar possíveis reações clínicas provocadas pela resposta imuno-alérgica intradérmica à tuberculina. Utilizou-se 30 ovinos, distribuídos por 3 grupos de 10 animais cada, a saber: A sensibilizados M. avium; B sensibilizados M. bovis e C – não sensibilizado (controle) – que receberam injeção de solução fisiológica. Após 45 dias da sensibilização, realizou-se o Teste Cervical Comparativo (TCC) com reação medida pela variação da espessura da pele com cutímetro de mola, nos seguintes momentos: antes da aplicação das tuberculinas (PPDs -derivado protéico purificado), 12h, 24h, 48h, 72h e 96h após a aplicação. Em relação à reação ao PPD bovino, no Teste Cervical Simples (TCS), lido às 72h (± 6 horas) pós-tuberculinização (p. t.), considerou-se uma reação positiva, quando o aumento da espessura da pele foi igual ou maior que 2,40 mm; como inconclusiva, com aumento entre 1,00 e 2,40 mm, e como reação negativa, aumentos da espessura da pele inferiores a 1 mm. A análise dos resultados da leitura do TCC, realizada às 72h p. t., permitiu concluir que o animal poderá ser considerado com resposta: positiva, quando a reação ao PPD bovino superar aquela ao aviário em pelo menos 2 mm; inconclusiva, quando a reação ao PPD bovino for maior que aquela ao aviário, com diferença entre 1 e 1,90 mm, e negativa quando a reação bovina for menor que a aviária ou maior em até 0,90 mm. Estes valores obtidos para o TCS e TCC são propostos como padrão de interpretação desses testes em ovinos.

Abstract:

ABSTRACTIn the present communication we have studied the isoenzymatic pattern activity of the glucose 6-phosphate dehydrogenase (G6PD) in Oesophagostomum venulosum, Trichuris ovis and T. suis, parasites of Capra hircus (goat), Ovis aries (sheep) and Sus scrofa domestica (pig) respectively, by polyacrylamide gel electrophoresis. Different phenotypes have been observed in the G6PD isoenzymatic pattern activity in males and females of Oesophagostomum venulosum. Furthermore, G6PD activity has been assayed in Trichuris ovis collected from Ovis aries and Capra hircus. No differences have been observed in the isoenzymatic patterns attending to the different hosts. All the individuals exhibited one single band or two bands; this suggests a monomeric condition for G6PD in T. ovis. In T. suis the enzyme G6PD appeared as a single electrophoretic band in about 85·7% of the individuals.

Abstract:

Bone is a tissue that has a density of extracellular matrix structures and composed by organic and inorganic components. Decalcification is a stage that plays an important role in bone histology using various types of solutions. The sample used in this study was lateral condyle from tibia of three garut sheeps (Ovis aries) which had been fixed with 10% Neutral Buffered Formalin (NBF) for 24 hours. Sample were cut into pieces ranging from 1 cm x 1 cm x 1 cm in size, the decalcification using three solutions; 10% nitric acid, 10% EDTA (pH 7.4) and 10% EDTA (pH 7.4) + TBD-1®. The aim of this study was to evaluate the effectiveness of three solutions for the decalcification process of lateral tibial condyle of garut sheep. Observation parameter in this study includes: duration of decalcification, sectioning process of ribboning formation, structural integrity and absorption of hematoxylin-eosin (HE) staining. The results shows that 10% EDTA (pH 7.4) solution provides a long duration of decalcification which is ease sectioning process ribboning, the best structural integrity of lateral tibial condyle. In hematoxylin-eosin (HE) staining shows that 10% nitric acid solution does not absorb the optimum color, opposite in 10% EDTA and 10% EDTA + TBD-1® solution, the color intensity between hematoxylin and eosin in the tissue shows the best results. Based on these results, it can be concluded that the 10% EDTA (pH 7.4) is the best decalcification solution for lateral condyle from tibial of garut sheeps.

Abstract:

With the recent rapid growth in transcatheter mitral and tricuspid valve interventions, it has become increasingly important to understand detailed anatomy of the valves. In this study, we investigated the similarities, differences, and associations between the dimensions of the atrioventricular valves in a sheep model, as sheep heart valves have a similar morphology to human valves. A systematic dissection of twenty-five sheep hearts was performed, with annular circumference measurement, and sub-valvular anatomy documentation. There was a significant association (r=0.865; p=0.007) between the circumference of the mitral and tricuspid annuli. Authors also identified significantly more chordae tendinea in the subvalvular mitral apparatus compared to the tricuspid valve (15.8±1.2 vs. 13.9±1.5; p<0.001). In conclusion, there is a significant association between the size of mitral and tricuspid valve annuli, and the morphology of leaflets and subvalvular apparatus is different between the two valves. These findings could have important implications in transcatheter device design, sizing, and optimal intervention timing.

Abstract:

The fecal egg count reduction test (FECRT) was used in a survey for anthelmintic resistance in 42 sheep farms, in five different regions in Paraná State, Brazil between July 1996 - July 2000. Animals with natural infection were tested. Five drugs were used individually or in combination - benzimidazole, imidazothiazole, ivermectin, milbemicina and closantel. Results showed that the prevalence of resistance to all anthelmintic was as high as 88.1% for benzimidazoles (oxfendazole), 78.6% for ivermectin, 56.4% for closantel, 38.7% for closantel + oxfendazole, 38% for levamisole, and 23.6% for moxidectin. There was multiple resistance in all tested farms. The most important infective larvae recovered from culture were Haemonchus contortus and Trichostrongylus colubriformis. The failure of the existing drugs in the State of Paraná is considered an important issue. Some proposals to improve the situation are suggested which include a change of attitude on anthelmintic use by sheepherders, veterinarians and sanitary authorities.

Abstract:

As veias hepáticas e seus setores de drenagem foram estudados em 40 fígados de ovinos. Em 35 órgãos o sistema venoso foi injetado com Neoprene Latex "650" e em seguida dissecado; nos outros 5 órgãos injetou-se acetato de vinyl (cores diferentes) para obtenção de moldes. Foram observados os lobos hepáticos e seus setores de drenagem das seguintes veias hepáticas e suas tributárias: veias hepáticas maiores (veia hepática esquerda, veia hepática média, veia hepática direita, veia hepática do processo caudado e veia hepática do processo papilar) e veias hepáticas menores. As veias hepáticas esquerda e médias.são os principais vasos de drenagem do sangue do fígado de Ovis aries, desembocando independentemente na veia cava caudal. A veia hepática direita termina na veia cava caudal como vaso único em 57,1% dos casos e junta-se à veia hepática do processo caudado ou veia hepática do processo papilar em 31,4% dos casos. A veia hepática direita ocorre em 88,6% dos casos, sendo em número de uma em maior frequência (51,4%), de duas (22,9%) ou de três (14,3%) veias. Em alguns casos a vaia hepática do processo caudado forma um tronco com a veia hepática direita e/ou a veia hepática do processo papilar (11,4%). Sozinha ou em conjunto com outras, a veia do processo caudado termina na veia cava caudal. A veia hepática do processo papilar chega independentemente na veia cava caudal em 71,4% dos casos. Sozinha ou em conjunto com a veia hepática do processo caudado e/ou a veia hepática direita, desemboca na veia cava caudal. Veias hepáticas menores chegam diretamente à veia cava caudal, completando a drenagem dos setores dorsal e medial do lobo direito e da porção supraportal do lobo caudado. Em grande maioria dos casos existem anastomoses entre veias de segmentos anatomo-cirúrgicos adjacentes, limitados por regiões avasculares ou paucivasculares. A drenagem venosa hepática é formada por vasos independentes mas, interpostos com os vasos integrantes da rede portobiloarterial. A drenagem venosa inclui na maioria dos casos os seguintes anatomo-cirúrgicos: a) segmento da veia hepática esquerda (lobo esquerdo); b) segmento da veia hepática média (lobo quadrado, porção supraportal do lobo caudado e setores intermédio e lateral do lobo direito); c) segmento da veia hepática direita, tipicamente representado pelo setor dorsal do lobo direito; d) segmento da veia hepática do processo caudado; e) segmento da veia hepática do processo papilar. O setor medial do lobo direito é drenado pelas veias hepáticas menores.

Abstract:

A oestrose é uma miíase obrigatória e cavitária de ovinos e caprinos, domésticos e selvagens, causada por larvas da mosca Oestrus ovis (Linnaeus). Este estudo relata a presença de O. ovis na região Centro-Oeste do Brasil como parasitas de caprinos e ovinos. Nós obtivemos seis larvas de ovinos e caprinos suspeitos de oestrose em Brasília. As larvas originaram duas moscas fêmeas adultas de O. ovis, após 20 e 23 dias respectivamente. Este achado está provavelmente associado à expansão e diversificação da agricultura no cerrado do planalto central brasileiro. Ovis aries (Artiodactyla: Bovidae) and Capra hircus (Artiodactyla: Bovidae) infected by Oestrus ovis (Diptera: Oestridae) in the Federal District, Brazil Abstract. The Oestrosis is an obligatory and cavitary myiasis of sheep and goat, wild and domestic, caused by the larvae of Oestrus ovis (Linnaeus) fly. This study records the presence of O. ovis in the West Central region of Brazil as parasites of goats and sheep. We obtained six larvae from sheep and goats with suspects of oestrosis in Brasília (Brazil) originate two females adult of O. ovis, after 20 and 23 days respectively of pupation. This finding is probably associated with expansion and diversification of farming in the Cerrado of the Brazilian central plateau.
