Abstract: After the Puerto Rico Department of Health received a report of salmonellosis in an infant who had contact with a pet turtle, we conducted a case-control study in two urban areas in Puerto Rico to measure the extent of pet turtle-associated salmonell...
Abstract:
Abstract: A commercial turtle pond in South Louisiana was studied to identify the mechanism by which turtle hatchlings acquire Salmonella flora. The visceral organs and mature eggs removed from 31 adult gravid female turtles over the course of two egg-laying s...
Abstract: Despite intense interest in conservation of marine turtles, spatial ecology during the oceanic juvenile phase remains relatively unknown. Here, we used mixed stock analysis and examination of oceanic drift to elucidate movements of hawksbill turtles ...
Abstract:
Abstract: Turtles have been known since the Upper Triassic (210Myr old); however, fossils recording the first steps of turtle evolution are scarce and often fragmentary. As a consequence, one of the main questions is whether living turtles (Testudines) origina...
Abstract: We verified whether telomere length shortens with age in the loggerhead sea turtle (Caretta caretta) by measuring telomere lengths (relative telomere to single copy gene [T/S] ratios) in whole blood and epidermis from 20 captive individuals with a re...
Abstract: Turtles have a body plan unique among vertebrates in that their ribs have shifted topographically to a superficial layer of the body and the trunk muscles are greatly reduced. Identifying the developmental factors that cause this pattern would furthe...
Abstract:
Abstract: Spleen and thymus suspensions from the turtle, Chelydra serpentina were examined by indirect immunofluorescence with a rabbit anti-turtle thymocyte serum (RATT). After the species-specific antibodies had been absorbed out, the antisera labeled all ly...
Abstract: Common snapping turtles, Chelydra serpentina (Linnaeus), were submerged in anoxic and normoxic water at 3 degrees C. Periodic blood samples were taken, and PO(2), PCO(2), pH, [Na(+)], [K(+)], [Cl(-)], total Ca, total Mg, [lactate], [glucose], hematoc...
Abstract: Turtle populations are decreasing dramatically due to habitat loss and collection for the food and pet market. This study sought to determine hematologic values in two species of turtles to help assess health status of captive and wild populations. B...
Abstract: Chelodina oblonga is a long-necked, freshwater turtle found predominantly in the wetlands on the Swan Coastal Plain of Western Australia. Turtles from three populations were recorded in artificial environments set up to simulate small wetlands. Recor...
Abstract: The complete mitochondrial genome (16,837 bp) from the Keeled box turtle (Pyxidea mouhotii) was determined. The genome content, gene order, and base composition conformed to the consensus vertebrate type mtDNA. However, a remarkable feature was found...
Abstract: Turtles have the most unusual body plan of the amniotes, with a dorsal shell consisting of modified ribs. Because this morphological change in the ribs can be described as an axial-level specific alteration, the evolution of the turtle carapace shoul...
Abstract: The turtle shell forms by extensive ossification of dermis ventrally and dorsally. The carapacial ridge (CR) controls early dorsal shell formation and is thought to play a similar role in shell growth as the apical ectodermal ridge during limb develo...
Abstract: Finite element (FE) models are popular tools that allow biologists to analyze the biomechanical behavior of complex anatomical structures. However, the expense and time required to create models from specimens has prevented comparative studies from i...
Abstract: The oxygen consumption of rat versus turtle brain and heart slices was compared as a function of extracellular pH and temperature. At pH = 6.20 rat (mammalian) brain and heart slices show a significant depression of oxygen consumption as compared to ...
Abstract: Sea turtle fibropapillomatosis (FP) is a disease marked by proliferation of benign but debilitating cutaneous fibropapillomas and occasional visceral fibromas. Transmission experiments have implicated a chloroform-sensitive transforming agent present...
Abstract: A subadult loggerhead turtle, Caretta caretta, presented with generalized small, white, raised lesions over its neck, shoulders, and all four flippers. A juvenile green turtle, Chelonia mydas, recently treated for fibropapillomatosis, presented with ...
