Diseases of frogs and toads 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...

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

Attempts to identify the source of avian vacuolar myelinopathy for waterbirds Attempts to identify the source of avian vacuolar myelinopathy for waterbirds

Attempts were made to reproduce avian vacuolar myelinopathy (AVM) in a number of test animals in order to determine the source of the causative agent for birds and to find a suitable animal model for future studies. Submerged vegetation, plankton, invertebrates, forage fish, and sediments were collected from three lakes with ongoing outbreaks of AVM and fed to American coots (Fulica...

Epizootiology of spirorchid infection in green turtles (Chelonia mydas) in Hawaii Epizootiology of spirorchid infection in green turtles (Chelonia mydas) in Hawaii

We describe the epizootiology of spirorchiid trematode infections in Hawaiian green turtles (Chelonia mydas) by quantifying tissue egg burdens in turtles submitted for necropsy and by assessing antibody response to crude adult worm and egg antigens among a variety of age groups. Hapalotrema sp. and Laeredius sp. predominated in turtles infected with spirorchiids. Tissue egg burdens...

Mortality in the endangered Laysan teal, Anas laysanensis: conservation implications Mortality in the endangered Laysan teal, Anas laysanensis: conservation implications

The Laysan Teal Anas laysanensis is an endangered anatid of the Hawaiian Islands, currently restricted to an emergent atoll, Laysan Island. Laysan Island lacks terrestrial mammalian predators, which permits the examination of mortality rates and causes without the anthropogenic effects of introduced predators. Mass and morophometrics were measured during the colour-marking of 297 Laysan...

Lichens of the U.S. National Parks Lichens of the U.S. National Parks

Over 26,100 records of lichens present in 144 U.S. national park units were assembled from various sources into a database and analyzed. Within these 144 park units 2,435 species and 375 genera are reported, representing 63% and 74% of the North American flora, respectively. The park units are located in 41 states and Washington, D.C. The average number of species in a park is 104, but...

Associations between water quality, Pasteurella multocida, and avian cholera at Sacramento National Wildlife Refuge Associations between water quality, Pasteurella multocida, and avian cholera at Sacramento National Wildlife Refuge

We studied patterns in avian cholera mortality, the presence of Pasteurella multocida in the water or sediment, and water chemistry characteristics in 10 wetlands at the Sacramento National Wildlife Refuge Complex (California, USA), an area of recurrent avian cholera epizootics, during the winters of 1997 and 1998. Avian cholera outbreaks (≥50 dead birds) occurred on two wetlands during...

Diseases of amphibian eggs and embryos 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...

Geographic variation in marine turtle fibropapillomatosis Geographic variation in marine turtle fibropapillomatosis

We document three examples of fibropapillomatosis by histology, quantitative polymerase chain reaction (qPCR), and sequence analysis from three different geographic areas. Tumors compatible in morphology with fibropapillomatosis were seen in green turtles from Puerto Rico and San Diego (California) and in a hybrid loggerhead/ hawksbill turtle from Florida Bay (Florida). Tumors were...
