Genomic variation of the fibropapilloma-associated marine turtle herpes virus across seven geographic areas and three host species

Fibropapillomatosis (FP) of marine turtles is an emerging neoplastic disease associated with infection by a novel turtle herpesvirus, fibropapilloma-associated turtle herpesvirus (FPTHV). This report presents 23 kb of the genome of an FPTHV infecting a Hawaiian green turtle (Chelonia mydas). By sequence homology, the open reading frames in this contig correspond to herpes simplex virus genes UL23

Diseases of amphibian eggs and embryos

Amphibians generally are prolific egg producers. In tropical and semi-tropical regions, deposition of eggs may occur year-round or may coincide with rainy seasons, while in temperate regions, deposition of eggs usually occurs immediately after emergence from hibernation. Numbers of eggs produced by each species may vary from a few dozen to thousands. Accordingly, some eggs may be infertile and was

Diseases of tadpoles

This chapter is devoted to the diseases of anuran larvae that cause morbidity( illness) and mortality (death). The purpose of this chapter is to describe diseases that may be encountered in free-living tadpoles of the United States and Canada. Much of the information in this chapter comes from unpublished diagnostic examinations of amphibians done at the U.S. Geological Survey, National Wildlife H

Diseases of salamanders

Few diseases are reported in salamanders. Two notable exceptions are infections by Ranavirus and Ichthyophonus. Except for mortality events associated with ranaviruses in tiger salamanders (Ambystoma tigrinum) and spotted salamanders (A. maculatum), dieoffs of salamanders are rarely detected or reported. Diseases presented in this chapter are those encountered in free-living salamanders of the Uni

Wildlife health and disease investigations

Wildlife population management requires knowledge of factors that affect population sustainability. Mortality is one of the most important of those factors. Without a clear understanding of the causes of mortality, decisions by managers of whether or how to intercede may be inappropriate. Wildlife biologists are usually the first to discover, assess, and respond to wildlife mortality. Biologists w

Diseases of frogs and toads

This chapter presents information on infectious diseases of free-living frogs and toads that have completed metamorphosis. The diseases discussed in this chapter pertain principally to sub-adult and adult frogs and toads that are at least 60-90 days removed from completion of metamorphosis. The main emphasis of this chapter is the diseases found in amphibians of Canada and the United States. Disea

Amphibian Research and Monitoring Initiative (ARMI): A successful start to a national program in the United States

Most research to assess amphibian declines has focused on local-scale projects on one or a few species. The Amphibian Research and Monitoring Initiative (ARMI) is a national program in the United States mandated by congressional directive and implemented by the U.S. Department of the Interior (specifically the U.S. Geological Survey, USGS). Program goals are to monitor changes in populations of am
