Autonomic control of heart rate is virtually independent of temperature but seems related to the neuroanatomy of the efferent vagal supply to the heart in the bullfrog, Lithobathes catesbeianus
(Pergamon-Elsevier B.V. Ltd, 2012-04-01)
Bullfrogs, Lithobathes catesbeianus, bearing a femoral artery cannula were held at 3 temperatures (10,20 and 30 degrees C) for 24 h. Changes in heart rate were recorded before and after injection of cholinergic and adrenergic ...
Median lethal concentration of formaldehyde and its genotoxic potential in bullfrog tadpoles (Lithobates catesbeianus)
(2015-01-01)
In order to avoid that contaminated frog farms animals escaping in the environment and become potential vector of emergent diseases, studies with disinfection protocol are strictly necessary. The formaldehyde is one of the ...
Liver lesions produced by aflatoxins in Rana catesbeiana (bullfrog)
(Elsevier B.V., 2007-09-01)
This study describes alterations induced in Rana catesbeiana (bullfrog) liver after extended dietary exposure to aflatoxins (AFs). Bullfrogs of both sexes were fed for 120 days a commercial chow blended with a rice bran-based ...

Pathogenic fungus in feral populations of the invasive North American bullfrog in Argentina
(Soc Royale Zoologique Belgique, 2017-06)
Nearly a third (32.4%) of the world?s amphibian species are either threatened with extinction or already extinct (1). The chytrid fungus Batrachochytrium dendrobatidis (Bd) (Chytridiomycetes: Ryzophydiales) (2) has been ...
Widespread occurrence of the American Bullfrog, Lithobates catesbeianus (Shaw, 1802) (Anura: Ranidae), in Brazil
(Brazilian Society of HerpetologySão Paulo, 2011-08)
We report new records of Lithobates catesbeianus feral populations in Brazil. Data were based on fieldwork, natural
history collection records, and literature and electronic database searches. Lithobates catesbeianus ...
Fatty acid composition, extraction, fractionation, and stabilization of bullfrog (Rana catesbeiana) oil
(1998)
The oil extracted from the fat-storage organ (fat body) of the bullfrog (Rana catesbeiana) was characterized for its fatty acid composition. The main fatty acids were palmitic (18.1%), stearic (4.1%), myristic (2.7%), oleic ...
