Orbital Implants Insertion to Improve Ocular Prostheses Motility

The objectives of this study were, through a literature review, to point the differences between orbital implants and their advantages and disadvantages, to evaluate prosthesis motility after orbital implants are inserted, and to point the implant wrapping current risks. Sixty-seven articles were reviewed. Enucleation implants can be autoplastics or alloplastics and porous (including natural and synthetic hydroxyapatite [HA]) or nonporous (silicone). Hydroxyapatite is the most related in the literature, but it has disadvantages, too, that is, all orbital implants must be wrapped. Exposure of the porous orbital implant can be repaired using different materials, which include homologous tissue, as well as autogenous graft, xenograft, and synthetic material mesh. The most used materials are HA and porous polyethylene orbital implant. The HA implant is expensive and possibly subject corals to damage, different from porous polyethylene orbital implants. Porous implants show the best prosthesis motility and a minimum rate of implants extrusion. Implant wraps can facilitate smoother entry of the implant into the orbit and allow reattachment of extraocular muscles. They also serve as a barrier between the overlying soft tissue and the rough surface of the implant, protecting implants from exposure or erosion.

Resistance of Santa Ines, Suffolk and Ile de France sheep to naturally acquired gastrointestinal nematode infections

A study was conducted to assess the breed resistance against nematode infections in Santa Ines, Ile de France and Suffolk male lambs over a 9-month period in São Paulo state, Brazil. Lambs were born during the winter (year 2000) and were weaned at 2 months of age. The animals were then housed and treated with anthelmintics to eliminate natural infections by gastrointestinal nematodes. In late October 2000, lambs were placed in a paddock, where they stayed until August of the following year. Fecal and blood samples were taken from each animal every 2 weeks. on the same day, a pasture sample was collected to determine the number of infective larvae on the herbage. To prevent deaths, individual treatment with anthelmintics was provided to lambs with fecal egg counts (FEC) higher than 4000 eggs per gram (EPG) or with a packed cell volume (PCV) lower than 21%. In August 2001, all animals were slaughtered and the worms present in samples of the gastrointestinal contents were identified and counted. Most of the Suffolk and Ile de France sheep received three to six anthelmintic treatments over a period of 7 months, while most of the Santa Ines were not treated. Reductions in PCV and plasma protein values associated with high FEC and worm burdens were recorded, particularly, in Suffolk and Ile de France lambs. Haemonchus contortus and Oesophagostomum columbianum burdens and number of nodular lesions caused in the large intestine by O. columbianum larvae were significantly lower in Santa Ines sheep. All three breeds showed similar Trichostrongylus colubriformis worm burdens. The relative resistance of Santa Ines young male sheep was superior to that of Suffolk and Ile de France sheep.

Occurrence of gastrointestinal parasites in goat kids

Amostras fecais de cabritos machos e fêmeas, de diferentes raças e com até uma ano de idade, foram examinadas para determinação do número de ovos e oocistos por grama de fezes (OPG e OoPG, respectivamente) e coprocultura para identificação genérica dos nematódeos. Ovos de helmintos e oocistos de Eimeria spp. foram observados em 93,06% (188/202) e 77,22% (156/202) das amostras, respectivamente. Pelas coproculturas, foram identificados os gêneros Cooperia em 11,88% (24/202), Haemonchus em 51,98% (105/202), Oesophagostomum em 9,4% (19/202), Strongyloides em 5,94 (12/202) e Trichostrongylus em 20,79% (42/202) das amostras. As espécies de Eimeria encontradas foram E. alijevi em 25,24% (51/202), E. arloingi em 7,42% (15/202), E. caprina em 2,97% (6/202), E. caprovina em 10,39% (21/202), E. christenseni em 4,45% (9/202), E. joklchijevi em 11,38% (23/202), E. hirci em 9,4% (19/202) e E. ninakohlyakimovae em 28,71% (58/202) das amostras. Dentre os parasitas gastrintestinais, houve predominância do gênero Haemonchus e de duas espécies de Eimeria: E. ninakohlyakimovae e E. alijevi.

Gastrointestinal parasites in goats from Monte Castelo, Santa Catarina, Brazil

Este trabalho foi realizado com o objetivo de estimar o grau de infecção dos helmintos gastrintestinais em um rebanho caprino criado no Planalto Norte Catarinense. Foram utilizadas 12 fêmeas jovens e 11 adultas, das quais, a cada 28 dias, foram coletadas amostras de fezes diretamente do reto, totalizando 12 coletas, para quantificação de ovos por grama de fezes (OPG) e cultivo de larvas através de pool das amostras positivas do mesmo grupo. A contagem de OPG variou de zero a 10.400 nos animais jovens e de zero a 7.600 nos adultos. As médias do OPG entre as coletas foram de 583,3 a 4.441,7 no grupo jovem e de 418,2 a 2.181,8 nos adultos, sendo observados ovos da ordem Strongylida, dos gêneros Moniezia e Toxocara, bem como oocistos de coccídeos. Os animais mais jovens foram os mais acometidos, sendo o gênero Haemonchus o mais prevalente.

Evaluation of reduction in egg shedding of gastrointestinal nematodes in cattle following administration of anthelmintics

No intuito de avaliar o tempo necessário para redução dos valores de OPG visando identificar o início de atuação dos anti-helmínticos, cinco grupos de novilhos, naturalmente infectados por nematódeos gastrintestinais foram tratados com moxidectina, ivermectina, fosfato de levamisol e sulfóxido de albendazol. O levamisol promoveu redução no número de ovos de nematódeos eliminados nas fezes (R-OPG) de 97,4% 24 horas após a aplicação, a moxidectina de 98,3% após 36 horas, e o sulfóxido de albendazol de 95,9% após 36 horas. Foi registrada a presença de Cooperia spp. e Haemonchus spp. com resistência a ivermectina. A contagem de OPG realizada aos sete dias pós-tratamento apresentou resultados similares aos obtidos nas contagens realizadas 10 e 14 dias após a aplicação dos anti-helmínticos avaliados, demonstrando que o intervalo adequado entre o tratamento anti-helmíntico e o exame para verificar a redução do OPG pode ser de 7 dias.
