RESUMO
A tartaruga-verde, Chelonia mydas, apresenta distribuição cosmopolita. No Brasil, ocorre na costa, porém desova em ilhas oceânicas. A helmintofauna de tartarugas-verdes é diversificada, podendo-se dizer que tem a maior diversidade comparada com outras espécies de tartarugas. Objetivou-se avaliar aspectos ecológicos da comunidade de helmintos gastrointestinais e relacionar com a condição corporal de tartarugas-verdes recolhidas no litoral do Espírito Santo. Foram utilizados 36 exemplares juvenis da espécie C. mydas. O trato gastrointestinal foi separado e dividido em porções esôfago/estômago, intestino delgado e intestino grosso. Cada porção foi inspecionada à procura de parasitos, e os exemplares encontrados foram separados para posterior identificação. Das 36 tartarugas avaliadas, 34 estavam parasitadas por helmintos (94,44%), com um total de 10.734 helmintos. Foram encontradas 18 espécies de trematodas pertencentes a quatro famílias. A riqueza de espécies encontrada foi de 4,29±2,19 (1-10) e a intensidade média de infecção foi de 315,64±281,83 (2-994) helmintos. Os parasitos mais prevalentes foram Cricocephalus albus, Metacetabulum invaginatum e Neoctangium travassosi, ambos com 61,11% (22/36), Pronocephalus obliquus com 33,33% (12/36), e Glyphicephalus lobatus com 30,55% (11/36). O helminto mais abundante foi M. invaginatum com 70,63 helmintos/animal, seguido de C. albus com 58,77 helmintos/animal e N. travassosi com 41,75 helmintos/animal.(AU)
ABSTRACT
The green turtle, Chelonia mydas has worldwide distribution. In Brazil, it is found on the coast, but spawning occurs on oceanic islands. The helminth fauna of green turtles is diverse and has the greatest diversity when compared with other species of turtles. This study aims to evaluate ecological aspects of gastrointestinal helminth community and connect to the body condition of green turtles collected on the coast of Espírito Santo. A total of 36 juvenile specimens of the species C. mydas were used. The gastrointestinal tract was removed and divided into portions esophagus/stomach, small intestine and large intestine. Each portion was inspected looking for parasites and the specimens found were separated for later identification. Of the 36 turtles evaluated, 34 were parasitized by helminths (94.44%), with a total of 10,734 helminths. Results include findings of 18 species of trematodes belonging to four families. The species richness was 4,29 ± 2,19 (1-10) and the mean intensity of infection was 315,64 ± 281,83 (2-994) helminths. The prevalent parasites were Cricocephalus albus, Metacetabulum invaginatum and Neoctangium travassosi, both with 61,11% (22/36), Pronocephalus obliquus with 33,33% (12/36), and Glyphicephalus lobatus with 30,55% (11/36). The abundant helminth was Metacetabulum invaginatum with helminths 70,63/animal, followed by C. albus with helminths 58,77/animal and N. travassosi with helminths 41,75/animal.(AU)
