Ultraviolet radiation-induced genotoxic effects in the broad-snouted caiman, Caiman latirostris

Mutation Research/Genetic Toxicology and Environmental Mutagenesis, 2010
Ultraviolet radiation (UVR) has many positive effects, but overexposure of organisms can generate alterations in DNA, either directly or indirectly, inducing mutagenic and cytotoxic lesions. The aim of this study was to evaluate the genotoxic effects of UVA-B/visible light in the broad-snouted caiman (Caiman latirostris), using the micronucleus (MN ...

Blood biochemistry parameters of Broad snouted caiman, Caiman latirostris subjected to stress conditions, appliying micro‐volume techniques

Journal of Experimental Zoology Part A: Ecological and Integrative Physiology, 2023
AbstractPlasma biochemistry values represent a crucial and minimally invasive tool for evaluating nutritional and physiological condition of the animal. Biochemical data provides valuable information in those species exposed to environmental stressors.

ISOLATION OF SALMONELLA SPP. FROM YACARE CAIMAN (CAIMAN YACARE) AND BROAD-SNOUTED CAIMAN (CAIMAN LATIROSTRIS) FROM THE ARGENTINE CHACO

Journal of Wildlife Diseases, 2011
Presence of Salmonella spp. was evaluated in yacare caiman (Caiman yacare) and broad-snouted caiman (Caiman latirostris) from a ranching facility in the Argentine Chaco. Crocodilian ranching programs are based on captive breeding of wild-harvested eggs and release of excess hatchlings into the wild.

Corticosterone levels and immunological indices in stressed juvenile broad‐snouted caimans

Journal of Zoology, 2017
AbstractThe effect of stress in wild vertebrates has been little investigated, especially in crocodilians. In the wild, crocodilians face numerous stressors such as climatic factors, toxicant exposure, and infection. Exposure to stressors may affect the physiological processes of crocodilians, with consequences on its fitness and survival.

Postnatal development and histofunctional differentiation of the oviduct in the broad-snouted caiman (Caiman latirostris)

General and Comparative Endocrinology, 2016
Caiman latirostris is a South American crocodilian species characterized as a sentinel of the presence of endocrine-disrupting compounds (EDCs). Evaluating developmental events in hormone-dependent organs, such as the oviduct, is crucial to understand physiological postnatal development, to identify putative periods of exposure sensitive to EDCs, and ...

Combined metabolic bone diseases, medullary aplasia and bacterial pneumonia in broad-snouted caiman (Caiman latirostris)

Aquaculture, 2020
Abstract Seven juvenile broad-snouted caiman (Caiman latirostris), bred in captivity and subjected to a diet deficient in minerals and vitamins during the first months of life, developed intense cachexia and generalized loss of bone stiffness.

Genotoxicity induced by widely used pesticide binary mixtures on Caiman latirostris (broad-snouted caiman).

Chemosphere, 2019
In this study, we investigated the effects of three binary mixtures of pesticide formulations commonly used in soybean crop: Cypermethrin Atanor® (25% -CYP), Chlorpyrifos Lorsban 48E® (48% -CPF) and Glyphosate Roundup® Full II (66.2% -GLY) on broad-snouted caiman (Caiman latirostris) hatchlings exposed by voluntary immersion under controlled condition.

The temperature-sensitive period (TSP) during incubation of broad-snouted caiman (Caiman latirostris) eggs

Amphibia-Reptilia, 2007
Abstract All crocodiles studied to date exhibit temperature-dependent sex determination. During the many weeks from egg laying to hatch there is a period of 10 to 15 d in the middle third of incubation (in the American alligator) during which the sex of the embryo is irreversibly fixed ...

Exposure to atrazine and endosulfan alters oviductal adenogenesis in the broad-snouted caiman (Caiman latirostris)

Environmental Science and Pollution Research
The molecular pathways involved in oviductal adenogenesis are highly conserved among vertebrates. In this work, we study the histomorphological changes and molecular pathways involved in Caiman latirostris oviductal adenogenesis and the effects of in ovo exposure to environmentally relevant doses of endosulfan (END) and atrazine (ATZ) on these ...
