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

Diet of Bullfrog Tadpoles Lithobates catesbeianus, Shaw 1802, an Invasive Species from Monte Desert
, 2022 The competitive effects among tadpoles make the bullfrog a possible agent of native amphibian population declines at its introduction sites. Our aim was to analyze the dietary composition of an invasive population of Lithobates catesbeianus tadpoles and ...

Immune and hormonal modulation in the postprandial period of bullfrogs (Lithobates catesbeianus)
Journal of Experimental Biology, 2021 ABSTRACT Mammals show immune up-regulation and increased plasma and local (gastrointestinal tract) concentrations of some immunoregulatory hormones, such as corticosterone and melatonin, after feeding. However, little is known about the endocrine and immune modulation in the postprandial period of ectothermic animals.

Morphological characterization of the gonads of bullfrog tadpoles (Lithobates catesbeianus) [PDF]
Journal of Morphological Sciences, 2015 Abstract Introduction: This work describes various aspects of early gonadal development of female and male in pre-metamorphic tadpoles (Lithobates catesbeianus) at Gosner stage 25. Materials and Methods: Ovaries and testicles were prepared for routine light microscopy for morphological study and for acridine orange technique fluroescent ...
