The story of invasive algae, arginine, and turtle tumors does not make sense The story of invasive algae, arginine, and turtle tumors does not make sense
We are presenting a rebuttal letter to the following article that appeared recently on PeerJ: Van Houtan KS, Smith CM, Dailer ML, and Kawachi M. 2014. Eutrophication and the dietary promotion of sea turtle tumors. PeerJ 2:e602. This article is available at the following URL: https://peerj.com/articles/602/. We argue that the article lacks an inferential framework to answer the complex...

Mycoplasmosis and upper respiratory tract disease of tortoises: a review and update Mycoplasmosis and upper respiratory tract disease of tortoises: a review and update
Tortoise mycoplasmosis is one of the most extensively characterized infectious diseases of chelonians. A 1989 outbreak of upper respiratory tract disease (URTD) in free-ranging Agassiz's desert tortoises (Gopherus agassizii) brought together an investigative team of researchers, diagnosticians, pathologists, immunologists and clinicians from multiple institutions and agencies. Electron...

Investigating the potential role of persistent organic pollutants in Hawaiian green sea turtle fibropapillomatosis Investigating 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...

Impacts of upper respiratory tract disease on olfactory behavior of the Mojave desert tortoise Impacts of upper respiratory tract disease on olfactory behavior of the Mojave desert tortoise
Upper respiratory tract disease (URTD) caused by Mycoplasma agassizii is considered a threat to desert tortoise populations that should be addressed as part of the recovery of the species. Clinical signs can be intermittent and include serous or mucoid nasal discharge and respiratory difficulty when nares are occluded. This nasal congestion may result in a loss of the olfactory sense...

Immunological evaluation of captive green sea turtle (Chelonia mydas) with ulcerative dermatitis Immunological evaluation of captive green sea turtle (Chelonia mydas) with ulcerative dermatitis
Ulcerative dermatitis (UD) is common in captive sea turtles and manifests as skin erosions and ulcers associated with gram-negative bacteria. This study compared clinically healthy and UD-affected captive turtles by evaluating hematology, histopathology, immunoglobulin levels, and delayed-type hypersensitivity assay. Turtles with UD had significantly lower weight, reduced delayed-type

Tumors in sea turtles: The insidious menace of fibropapillomatosis Tumors in sea turtles: The insidious menace of fibropapillomatosis
Early in July 2013, a colleague in New Caledonia reported the stranding of a green sea turtle on the far northwest of the island. The animal had washed up dead on a rocky beach with multiple large tumors on its neck and hind flippers. To all appearances, the turtle had fibropapillomatosis (FP), a tumor disease affecting marine turtles globally. This was the first known case of FP on the...
