The aim of this work was to determine prevalence of intestinal parasites in chosen farms and to compare the assessed levels. A total of 250 samples were collected from tree farms (88, 84 and 78). Farm 1 used binding stable of K 96 type without pasture, farm 2 used combibox stable technology and the cows were pastured during non lacting period, in the farm 3, the cows were pastured during their lactation period with approach in loose housing. The work focused on two groups of parasites: genus Eimeria (its overall prevalence was 10 %) and the family Trichostrongylida(13.6 %). In the individual farms, Eimeria reached prevalence of 7.9, 8.3 and 16.7 %, respectively. Trichostrongylids were present in 1.1, 14.3 and 24.4 % of samples in the respective farms. On farm 2, Trichuris and Strongyloides papilosus were also found (each only once). On farm 3, bunostomosis was diagnosed in two cases. The intesities of infections were very low in all cases. The possible correlation of parasitoses and age / performance of animals was assessed with the use of ?2 test, the correlation was however not demonstrated.

No. of bitstreams: 1 Wagner Mcklayton Alves de Souza.pdf: 593917 bytes, checksum: 7cc4ef2d8445b4e599bbc16f65b02221 (MD5) Previous issue date: 2008-02-29 / In vitro was evaluated the activity ovicidal and larvicidal of the extract dry Hidroalcoólico of alecrim pepper (Lippia sidoides Cham) on the development of eggs and larval of third apprenticeship L3 of nematódeos gastrintestinais (family Trichostrongylidae) of goats. The action ovicidal was accomplished through analysis probabilístic of evolution of the egg in its embryonic phases, it was used 50μL of saturated solution of sugar contends 40 buoyant eggs approximately in the extract with concentration of 1mg/ml, 2mg/ml, 5mg/ml, 10mg/ml, 20mg, 50mg/ml, 100mg/ml, 150mg/ml, 250mg/ml and 500mg/ml, being appraised in the period of time of 1, 3, 6, 12, 24, 48 and 72 hours, water distilled in the negative control and febendazole for 33mg/ml as positive control, all three times in a row. The results demonstrated that the concentration of 500mg/ml presented a probability of 2% of happening evolution of the egg of goat gastrointestinal nematodes. This result went superior to all the other tested groups, andsuperior to the group it controls positive. The activity larvicidal was evaluated through tests of efficiency of the extract Hidroalcoólico on buoyant larval of third stadium L3 in aqueous solution of 50μL and being applied on them the extract of alecrim pepper in the concentrations of 1mg/ml, 2mg/ml, 5mg/ml, 10mg/ml, 20mg, 50mg/ml, 100mg/ml, 150mg/ml, 250mg/ml and 500mg/ml, evaluated to the period time of 24, 48 and 72 hours, water distilled in the negative control and febendazole for 33mg/mL was used as positive control, being twice repeated. After the exhibition period to the extract the larval were counted and separated among alive and dead larval. The results revealed that again the concentration of 500mg/ml really presented result effective with action of 95,89%, that activity went superior again to all the tested groups, getting to overcome in a lot the group controls positive that in function of activity ovicidal already can it is demonstrating resistance anthelminthic. The crossing of the data of the two studies in vitro can reveal a possible activity anthelminthic of the EHA of Lippia sidoide Cham on gastrointestinal nematodes (family Trichostrongylidae). / Avaliou-se in vitro a atividade ovicida e larvicida do EHA de alecrim pimenta (Lippia sidoides Cham) sobre o desenvolvimento de ovos e larvas de terceiro estágio L3 de nematóides gastrintestinais de caprinos (família Trichostrongylidae). A ação ovicida foi realizada através de análise probabilística de evolução do ovo em suas fases embrionária, foi utilizado 50μL de solução saturada de açúcar contendo aproximadamente 40 ovos imersos em diferentes concentrações do EHA (1mg/mL 2mg/mL, 5mg/mL, 10mg/mL, 20mg/mL, 50mg/mL, 100mg/mL, 150mg/mL, 250mg/mL e 500mg/mL), sendo avaliadas no período de tempo de 1, 3, 6, 12, 24, 48 e 72 horas, água destilada no controle negativo e febendazole 33mg/mL como controle positivo, todos em triplicata. Os resultados demonstraram que a concentração de 500mg/ml apresentou uma probabilidade de 2% de ocorrer evolução do ovo de nematóides gastrintestinais de caprinos. Este resultado foi superior a todos os outros grupos testados, e superior ao grupo controle positivo. A atividade larvicida foi avaliada através de testes de eficiência do EHA sobre larvas de terceiro estágio L3 imersas em solução aquosa de 50μL e sendo aplicada sobre elas o extrato de alecrim pimenta nas concentrações de 1mg/mL, 2mg/mL, 5mg/mL, 10mg/mL, 20mg/mL, 50mg/mL, 100mg/mL, 150mg/mL, 250mg/mL e 500mg/mL e avaliadas ao período tempo de 24, 48 e 72 horas, foi utilizado água destilada no controle negativo e febendazole 33mg/ml como controle positivo, sendo repetidos mais duas vezes. Após o período de exposição ao EHA as larvas vivas foram contadas e separadas entre mortas. Os resultados revelaram que novamente a concentração de 500mg/ml apresentou resultado realmente efetivo com ação de 95,89%, essa atividade foi novamente superior a todos os grupos testado, conseguindo superar em muito o grupo controle positivo que em função de atividade ovicida já pode está demonstrando resistência anti helmíntica. O cruzamento dos dados dos dois estudos in vitro sugere significante atividade ovicida e larvicida do EHA de Lippia sidoide Cham sobre nematóideos gastrintestinais de caprinos (família Trichostrongylidae).
