Microcystin-leucine arginine causes brain injury and functional disorder in Lithobates catesbeianus tadpoles by oxidative stress and inflammation.

Aquatic Toxicology, 2023
Microcystin-leucine arginine (MC-LR) is a toxin commonly found in eutrophic waters worldwide, but its potential effects on amphibian brain toxicity and exposure mechanisms are unclear. In this study, Lithobates catesbeianus tadpoles were exposed to MC-LR

Toxic, genotoxic, mutagenic, and bioaccumulative effects of metal mixture from settleable particulate matter on American bullfrog tadpoles (Lithobates catesbeianus).

Environmental Pollution, 2023
Amphibians are more susceptible to environmental stressors than other vertebrates due to their semipermeable skin and physiological adaptations to living in very specific microhabitats.

Influence of temperature on the biomarker responses of bullfrog tadpoles (Lithobates catesbeianus) to 2-hydroxyatrazine exposure.

Aquatic Toxicology, 2023
The influence of temperature (25 and 32 °C) on the biomarker responses of bullfrog tadpoles (Lithobates catesbeianus) to different concentrations of the atrazine metabolite 2-hydroxyatrazine (2-HA, 0, 10, 50 and 200 ng.L-1, 16 days), was evaluated ...

Bullfrog (Lithobates catesbeianus) invasion in Uruguay

Biological Invasions, 2007
This is the first report of North American bullfrogs, Lithobates catesbeianus (=Rana catesbeiana), invasion in Uruguay. This Anura was introduced for farming proposes in 1987, but at present most of the farms are closed. At one of these closed farms, located at Rincon de Pando, Canelones, we report the occurrence of a feral population of L ...

Localization of hematopoietic cells in the bullfrog (Lithobates catesbeianus)

Cell and Tissue Research, 2009
Amphibians represent the first phylogenetic group to possess hematopoietic bone marrow. However, adult amphibian hematopoiesis has only been described in a few species and with conflicting data. Bone marrow, kidney, spleen, liver, gut, stomach, lung, tegument, and heart were therefore collected from adult Lithobates catesbeianus and investigated by ...

Glycosaminoglycans and glycoconjugates in the adult anuran integument (Lithobates catesbeianus)

Micron, 2010
Glycosaminoglycans (GAGs) from the integument of Lithobates catesbeianus were biochemically characterized and histochemically localized. Moreover, carbohydrate distribution was investigated using conventional and lectin histochemistry at light microscopy. Hyaluronan (HA), dermatan sulfate (DS) and a heparanoid were found in the integument. Sulfated and

Microcystin-leucine arginine exposure induced intestinal lipid accumulation and MC-LR efflux disorder in Lithobates catesbeianus tadpoles.

Toxicology, 2021
Few studies exist on the toxic effects of chronic exposure to microcystins (MCs) on amphibian intestines, and the toxicity mechanisms are unclear. Here, we evaluated the impact of subchronic exposure (30 days) to environmentally realistic microcystin ...

Cutaneous Bacterial Species from Lithobates catesbeianus can Inhibit Pathogenic Dermatophytes

Mycopathologia, 2014
Antibiotics are being successfully used to fight many infectious diseases caused by pathogenic microorganisms. However, new infectious diseases are continuously being identified, and some known pathogens are becoming resistant against known antibiotics.
