“…Bile usually has a dark green color, but it may change to a crystalline or thick appearance in the presence of parasites (FLINT et al, 2009). Mild granulomatous hepatitis and trematode R. similis were observed in the gallbladder of a C. mydas in Espírito Santo state, in southeastern Brazil (WERNECK et al, 2015b).…”

“…Infectious hepatitis in C. mydas includes granulomatous infiltrate and necrosis associated with Spirorchiidiasis, fungi or bacterial infections (RAIDAL et al, 1998;FLINT et al, 2009;STACY et al, 2010;WERNECK et al, 2015b;WORK et al, 2015a). It is interesting to note the distribution and intensity of melano-macrophages in the liver.…”

The green turtle Chelonia mydas as a marine and coastal environmental sentinels: anthropogenic activities and diseases Tartaruga-verde, Chelonia mydas, como sentinela do ambiente marinho e costeiro: atividades antrópicas e enfermidades AbstractThe green turtle Chelonia mydas is a widely distributed, slowly maturing species with a complex life cycle, using both oceanic and coastal environments. The species is exposed to different threats and is considered an environmental sentinel that indicates variation among, and the severity of hazards to marine ecosystems. This study aimed to describe both anthropogenic impacts, and infectious and parasitic diseases in C. mydas -including cases along the Brazilian coast -and implications for conservation. Bycatch is reported as the main threat to the conservation of this species, followed by debris ingestion, collisions with boats, dredging, and chronic environmental contamination. All of these impacts may directly or indirectly cause death, by facilitating contact with pathological agents and by increasing vulnerability to secondary diseases. The pathological agents associated with lesions include viruses, bacteria, fungi, protozoa, and helminths. Fibropapillomatosis is an example of a chronic disease characterized by cutaneous and visceral tumors that affects mostly juvenile C. mydas worldwide and is associated with the Chelonid herpesvirus 5. The bacterias Vibrio alginolyticus, Aeromonas hydrophila, and Pseudomonas fluorescens are found in the aquatic environment and among C. mydas lesions in various organs. Trematode adults and eggs of the family Spirorchiidae are also frequent in systemic cardiovascular diseases of C. mydas. The direct impacts of anthropogenic activities and diseases are synergistic and may affect the specie's health and conservation. Therefore, the monitoring and systematic diagnosing of diseases and causes of death -including necropsy, histopathology, and molecular exams -are necessary to assess a population's health, to support appropriate decisions of coastal management and to target future research topics that optimize C. mydas conservation. Key words: Bycatch. Conservation. Debris ingestion. Morbidity. Pathogenic agents. Sea turtle. ResumoA tartaruga-verde, Chelonia mydas, possui ampla distribuição geográfica, reprodução tardia e complexo ciclo de vida, habitando áreas costeiras e oceânicas. Devido a essas características, a espécie está exposta a diferentes tipos de ameaças e pode sinalizar sobre variações e a gravidade desses impactos ao longo do tempo no ecossistema, sendo considerada sentinela ambiental. Este trabalho teve por objetivo discorrer sobre relatos de atividades antrópicas impactantes e doenças infecciosas e parasitárias em C. mydas, com ênfase nas ocorrências no litoral brasileiro. A captura acidental em petrechos de pesca é uma das principais ameaças à conservação desses animais, assim como a ingestão de resíduos sólidos, colisão com embarcações, dragagens e bioacumulação de contaminantes químicos, os quais podem atuar diretament...

“…Goldberg et al (2013) report lesions caused by spirorchiid eggs in the lungs of a specimen of C. mydas found in the city of Florianópolis (state of Santa Catarina). Lesions caused by spirorchiid eggs have also been found in the liver of the same host in the state of Espírito Santo (Werneck et al, 2015a). Hapalotrema postorchis is a relatively large parasite that seems to have a predisposition for occupying arterial spaces, as evidenced in the majority of studies Santoro et al, 2007;Stacy et al, 2010;present report).…”

SummaryThis note reports the occurrence of Hapalotrema postorchis Rao 1976 collected from an aortic aneurysm in a green turtle (Chelonia mydas Linnaeus 1758) found on the coast of Brazil. Besides the vascular lesion, granulomatous reactions with foreign -body giant cells were found surrounding the parasite eggs in the heart, intestines, liver, pancreas, spleen, brain and kidneys. This paper presents the fi rst report of H. postorchis and accompanying lesions in a green sea turtle from the western South Atlantic Ocean.

“…The identification of the parasites was performed using the genus taxonomic key proposed by Blair (2005), the original description by Price (1939) as well as descriptions by Smith et al (1941), Caballero 1954, Mehrotra & Gupta (1978) and Werneck et al (2015). Descriptions by Price (1939), Smith et al (1941), Caballero (1954) and Werneck et al (2015) were used for the morphometric comparisons of R. similis (Table 1) and descriptions by Price (1939), Caballero (1954) and Mehrotra & Gupta (1978) were used for the comparison of R. intestinalis (Table 2).…”

SummaryThe present note describes the occurrence of Rhytidodoides intestinalis and Rhytidodoides similis (Digenea: Rhytidodidae) in the gallbladder of two juvenile green turtles (Chelonia mydas - Testudines, Cheloniidae) found on the coast of Brazil. Both were detected in gallbladder and intestine of green turtles: Rhytidodoides similis (United States, Panama, Costa Rica and Brazil) and R. intestinais (United States, Panama and Costa Rica). This note is the first report of R. intestinalis in Brazil and South-West Atlantic Ocean. Also the histological lesions caused by the parasites in one gallbladder are described.
