Predacious activity of Arthrobotrys spp isolates on infective Cooperia punctata larvae | Atividade predatória de isolados de Arthrobotrys spp sobre larvas infectantes de Cooperia punctata
1998
Jackson Victor de Araújo
Laboratory experiments were performed in order to investigate the capacity of isolates from the predacious fungi Arthrobotrys musiformis (isolate 3), A. conoides (isolate A) and A. robusta (isolates B and E) to trap and kill infective Cooperia punctata larvae. Two groups were formed for each isolate: group 1, fungi and infective larvae and group 2, infective larvae (control). There were statistical differences (p<0.05) between the predacious activity of one isolate of A. robusta (isolate E) when compared with the other isolates of Arthrobotrys spp (isolates A, B and 3). No statistical difference (p>;0.05) was found between the isolate E and the control. This indicates that there can be an existing variability within a fungus species or genus concerning the predation of infective C. punctata larvae. | Experimentos laboratoriais foram realizados para investigar a capacidade de isolados de fungos predadores das espécies Arthrobotrys musiformis (isolado 3), A. conoides (isolado A) e A. robusta (isolados B e E) de predar e matar larvas infectantes de Cooperia punctata. Dois grupos foram formados para o teste de cada isolado: grupo 1, fungos e larvas infectantes e grupo 2, larvas infectantes (controle). Houve diferença estatisticamente significativa (p<0,05) entre a atividade predatória do isolado E de A. robusta, quando comparado com todos os outros isolados de Arthrobotrys spp (isolados A, B e 3). Nenhuma diferença estatística (p>;0,05) foi encontrada entre o isolado E e o grupo controle. Isto pode indicar uma variação existente dentro de uma mesma espécie de fungo ou gênero quanto à predação de larvas infectantes de C. punctata.

To carry out the study, the stomachs of 36 animals were used, from which 28 were white lipped peccary and 8 colored peccary. The celiac artery was injected with colored neoprene - latex 650, through the thoracic portion of the aorta, so as to fill the arterial ramifications of this vessel, which were directed to the stomach chambers. Then the samples were fixed in a 10% aqueous formol solution, to be carefully dissected and examined. The results show that, in both species, this organ is supplied by the terminal branches of the celiac artery. The conclusions listed in this research are based on the statistics of this distribution pattern. | Para a realização deste estudo foram coletados os estômagos de 36 animais, 28 queixadas e 8 catetos. Através da porção torácica da aorta, a artéria celíaca recebeu injeção de neoprene-látex 650 corado com o objetivo de preencher ramificações arteriais deste vaso que se dirigiam aos compartimentos do estômago. Em seguida, as peças foram fixadas em solução aquosa a 10% para serem cuidadosamente dissecadas e analisadas. Os resultados mostraram que este órgão, em ambas as espécies, encontra-se suprido pela artéria celíaca em 100% das observações, sendo que nos queixadas, a trifurcação deste vaso, originando as artérias esplênica, gástrica esquerda e hepática, ocorreu com maior freqüência (71,41% ± 7,5), enquanto nos catetos o referido vaso originou principalmente (80% ± 14,14) o tronco gastroesplênico e a artéria hepática individual.
