Investigating differences across host species and scales to explain the distribution of the amphibian pathogen Batrachochytrium dendrobatidis. [PDF]
PLoS ONE, 2014 Many pathogens infect more than one host species, and clarifying how these different hosts contribute to pathogen dynamics can facilitate the management of pathogens and can lend insight into the functioning of pathogens in ecosystems.

Multihost saprobes are facultative pathogens of bullfrog Lithobates catesbeianus eggs [PDF]
Diseases of Aquatic Organisms, 2012 Pathogens that infect more than one host species create complex linkages in ecological communities. We tested whether saprobes that grow on multiple host species in aquatic systems can be facultative pathogens of amphibian eggs. We isolated oomycetes from dead arthropods, vertebrates, plant leaves, and frog eggs that coexisted in a small pond. Analysis

Lithobates catesbeianus (American Bullfrog) oocytes: a novel heterologous expression system for aquaporins. [PDF]
Biol Open, 2018 Xenopus laevis oocytes are a valuable tool for investigating the function of membrane proteins. However, regulations around the world, specifically in Brazil, render the import of Xenopus laevis frogs impractical, and, in some cases, impossible. Here, as an alternative, we evaluate the usefulness of the North American aquatic bullfrog Lithobates ...

Knowledge & Management of Aquatic Ecosystems, 2023 Biological invasions are a major cause of biodiversity and ecosystem services loss. However, information on distribution and impacts is limited for many alien species, restricting the development of local management measures. The aim of this study is: to

A new record for American Bullfrog (Lithobates catesbeianus) in San Juan, Argentina
Revista Mexicana de Biodiversidad, 2011 We report a new record of Lithobates catesbeianus (American bullfrog) from Argentina. L. catesbeianus was first introduced to San Juan Province 11 years ago in Calingasta Department, where the habitat is pre-cordilleran.

Frog meat microbiota (Lithobates catesbeianus) used in infant food [PDF]
Food Science and Technology, 2014 Captive breeding of bullfrog (Lithobates catesbeianus) is of great economic potential, mainly for its thighs and leather. The nutritional quality of frog meat includes properly balanced amino acids with a protein profile of high biological value, low fat and low cholesterol, and high digestibility due to its short chain molecule structure.

Sexually dimorphic skin glands in the invasive species Lithobates catesbeianus (Anura: Ranidae)
Amphibia-Reptilia, 2021 Abstract Males of most amphibian species possess specialized cutaneous glands, known as sexually dimorphic skin glands (SDSGs). SDSGs are usually clustered in specific body regions and are externally visible, but in some cases, external differences between males and females can be slight or absent, and the ...
