First record of black band disease in the Hawaiian archipelago: response, outbreak, status, virulence, and a method of treatment
A high number of coral colonies, Montipora spp., with progressive tissue loss were reported from the north shore of Kaua‘i by a member of the Eyes of the Reef volunteer reporting network. The disease has a distinct lesion (semi-circular pattern of tissue loss with an adjacent dark band) that was first observed in Hanalei Bay, Kaua‘i in 2004. The disease, initially termedMontipora banded tissue losAuthorsGreta S. Aeby, Thierry M. Work, Christina M. Runyon, Amanda Shore-Maggio, Blake Ushijima, Patrick Videau, Silvia Beurmann, Sean M. CallahanGross and microscopic lesions in corals from Micronesia
The authors documented gross and microscopic morphology of lesions in corals on 7 islands spanning western, southern, and eastern Micronesia, sampling 76 colonies comprising 30 species of corals among 18 genera, with Acropora, Porites, and Montipora dominating. Tissue loss comprised the majority of gross lesions sampled (41%), followed by discoloration (30%) and growth anomaly (29%). Of 31 cases oAuthorsThierry M. Work, Greta S. Aeby, Konrad A.

Packed cell volume (PCV), plasma biochemistry, visual body condition (BC), and calculated body condition index (BCI) were evaluated in 170 wild juvenile green sea turtles Chelonia mydas from an aggregation in the effluent canal of a steel mill in Brazil. Occurrence of cutaneous fibropapillomatosis (FP) was observed in 44.1% of the animals examined.

WorkDynamics of virus shedding and in situ confirmation of chelonid herpesvirus 5 in Hawaiian green turtles with Fibropapillomatosis
Cancers in humans and animals can be caused by viruses, but virus-induced tumors are considered to be poor sites for replication of intact virions (lytic replication). Fibropapillomatosis (FP) is a neoplastic disease associated with a herpesvirus, chelonid herpesvirus 5 (ChHV5), that affects green turtles globally. ChHV5 probably replicates in epidermal cells of tumors, because epidermal intranuclAuthorsThierry M. Work, Julie Dagenais, George H.

Leatherback turtles, Dermochelys coriacea, which have an irregular pink area on the crown of the head known as the pineal or ‘pink spot’, forage upon jellyfish in cool temperate waters along the western and eastern margins of the North Atlantic during the summer. Our study showed that the skeletal structures underlying the pink spot in juvenile and adult turtles are compatible with the idea of a pAuthorsJohn Davenport, T. Todd Jones, Thierry M. Work, George H. BalazsInvestigating the potential role of persistent organic pollutants in Hawaiian green sea turtle fibropapillomatosis
It has been hypothesized for decades that environmental pollutants may contribute to green sea turtle fibropapillomatosis (FP), possibly through immunosuppression leading to greater susceptibility to the herpesvirus, the putative causative agent of this tumor-forming disease. To address this question, we measured concentrations of 164 persistent organic pollutants (POPs) and halogenated phenols inAuthorsJennifer M. Keller, George H. Balazs, Frances Nilsen, Marc Rice, Thierry M. Work, Brenda A. JensenGross and microscopic pathology of hard and soft corals in New Caledonia
We surveyed the reefs of Grande Terre, New Caledonia, for coral diseases in 2010 and 2013. Lesions encountered in hard and soft corals were systematically described at the gross and microscopic level. We sampled paired and normal tissues from 101 and 65 colonies in 2010 and 2013, respectively, comprising 51 species of corals from 27 genera. Tissue loss was the most common gross lesion sampled (40%AuthorsThierry M. Work, Greta S. Aeby, Gregory Lasne, Aline TribolletGross and microscopic pathology of lesions in Pocillopora spp. from the subtropical eastern Pacific
Coral reefs are threatened by a variety of factors including diseases that have caused significant damage in some regions such as in the Caribbean. At present, no data are available on coral diseases in the Mexican Pacific where Pocillopora spp. is a dominant component of coral communities. Here, we describe gross and microscopic morphology of lesions found in pocilloporids at four sites in the MeAuthorsJenny Carolina Rodríguez-Villalobos, Axayácatl Rocha-Olivares, Thierry M.
