Identification of CD3+ T lymphocytes in the green turtle Chelonia mydas
To understand the role of the immune system with respect to disease in reptiles, there is the need to develop tools to assess the host's immune response. An important tool is the development of molecular markers to identify immune cells, and these are limited for reptiles. We developed a technique for the cryopreservation of peripheral blood mononuclear cells and showed that a commercially availabAuthorsF.A. Munoz, S. Estrada-Parra, A. Romero-Rojas, Thierry M. Work, E.

Over the past few decades, there have been increasing numbers of reports of diseases in marine turtles. Furthermore, in recent years, there have been documented instances of apparently new diseases emerging in these species of which the etiology and/or pathogenesis remain unknown. These instances i) raise concern for the survival of marine turtles, and ii) question the health and stability of theAuthorsMark Flint, Janet C. Patterson-Kane, C.J. Limpus, Thierry M. Work, David Blair, Paul C. MillsRise and fall over 26 years of a marine epizootic in Hawaiian green sea turtles
Estimates of chronic disease prevalence are needed to improve our understanding of marine disease epizootiology, which is poorly known for marine megafauna such as marine turtles. An emerging worldwide threat to green sea turtles (Chelonia mydas) is fibropapillomatosis (FP), which is a pandemic tumor-forming disease associated with herpesviruses. We report on a 26-yr FP epidemic in the Hawaiian ArAuthorsMilani Chaloupka, George H. Balazs, Thierry M. WorkIn vitro biology of fibropapilloma-associated turtle herpesvirus and host cells in Hawaiian green turtles (Chelonia mydas)
Fibropapillomatosis (FP) of green turtles has a global distribution and causes debilitating tumours of the skin and internal organs in several species of marine turtles. FP is associated with a presently non-cultivable alphaherpesvirus Chelonid fibropapilloma-associated herpesvirus (CFPHV). Our aims were to employ quantitative PCR targeted to pol DNA of CFPHV to determine (i) if DNA sequesters byAuthorsThierry M. Work, Julie Dagenais, George H. Balazs, Joanne Schumacher, Teresa D.

Surveys for lesions in corals were conducted at seven sites around Tutuila in June 2004 and January 2005. The objectives of the study were to document the distribution and prevalence of disease in the major genera of corals and crustose coralline algae, systematically describe gross and microscopic morphology of lesions in reef corals and determine whether there are seasonal differences in prevaleAuthorsG. Aeby, Thierry M. Work, D. Fenner, Eva DiDonatoPhase shift from a coral to a corallimorph-dominated reef associated with a shipwreck on Palmyra atoll
Coral reefs can undergo relatively rapid changes in the dominant biota, a phenomenon referred to as phase shift. Various reasons have been proposed to explain this phenomenon including increased human disturbance, pollution, or changes in coral reef biota that serve a major ecological function such as depletion of grazers. However, pinpointing the actual factors potentially responsible can be probAuthorsThierry M. Work, G.S. Aeby, J.E. MaragosBiomedical and veterinary science can increase our understanding of coral disease
A balanced approach to coral disease investigation is critical for understanding the global decline of corals. Such an approach should involve the proper use of biomedical concepts, tools, and terminology to address confusion and promote clarity in the coral disease literature. Investigating disease in corals should follow a logical series of steps including identification of disease, systematic mAuthorsThierry M. Work, Laurie L. Richardson, T. L. Reynolds, Bette L. WillisOvergrowth of fungi (endolithic hypermycosis) associated with multifocal to diffuse distinct amorphous dark discoloration of corals in the Indo-Pacific
Coral disease surveys in American Samoa and Hawai‘i revealed colonies with a distinct dark discoloration affecting 20–60% of the colony surface (Fig. 1a). In some cases, tissue loss with algal infiltration was present within discolored areas. On microscopy, these lesions had marked overgrowth of the coral skeleton and tissues with septate branching structures that stained positive with Grocott’s MAuthorsThierry M. Work, G.S. Aeby, F.G. Stanton, D. FennerCause-specific temporal and spatial trends in green sea turtle strandings in the Hawaiian Archipelago (1982-2003)
We investigated cause-specific temporal and spatial trends in sea turtle strandings in the Hawaiian Archipelago. Five species of sea turtle were recorded in 3,861 strandings over a 22-year period (1982–2003). Green turtles comprised 97% of these strandings with size and gender composition reflecting the demographic structure of the resident green turtle population and relative green turtle abundanAuthorsMilani Chaloupka, Thierry M.
