Microsatellite DNA library for Caiman latirostris
Journal of Experimental Zoology, 2002AbstractNew genetic markers were characterized for the broad‐snouted caiman (Caiman latirostris) by constructing libraries enriched for microsatellite DNA. Construction and characterization of these libraries are described in the present study. One microsatellite marker was developed from a (ACC‐TGG)nenriched microsatellite DNA library, and 12 ...

Detection of Leptospira spp. in Captive Broad-Snouted Caiman (Caiman latirostris)
EcoHealth, 2019Leptospira sp. is an important waterborne zoonotic bacterium, known to cause infection in animals and humans worldwide. The role of reptiles in the transmission of this microorganism is poorly understood and historically neglected. This study aimed to investigate the presence of anti-Leptospira spp.

Allometry of Reproduction in Wild Broad-Snouted Caimans (Caiman latirostris)
Journal of Herpetology, 2004We studied 20 nesting female Caiman latirostris and their clutches in Santa Fe Province, Argentina. We regressed clutch and egg parameters and hatchling size with several measurements of female size (ln-transformed) to evaluate the allometry of reproduction in the wild. Larger females produced relatively smaller clutches. Larger females produced larger

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 ...

Ultraviolet radiation-induced genotoxic effects in the broad-snouted caiman, Caiman latirostris
Mutation Research/Genetic Toxicology and Environmental Mutagenesis, 2010Ultraviolet 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 ...

Embryonic communication in Caiman latirostris.
Synchronous hatching is defined as the adjustment, coordination, and control of development and hatching periods among embryos. To achieve synchronization, embryos modify their duration of incubation period and hatching periods, either by delaying or accelerating their embryonic development through "metabolic compensation".Samuel Hilevski +3 more

Heterogeneity and polymerization of hemoglobins of Caiman latirostris (Crocodylia: Reptilia)
Comparative Biochemistry and Physiology Part B: Comparative Biochemistry, 1976Abstract 1. 1. The hemoglobins of Caiman latirostris were examined by starch gel electrophoresis and molecular sieving. 2. 2. Three major and one minor components were resolved by electrophoresis at pH 8.1 of freshly prepared and alkylated samples. 3. 3.

ABSTRACT Living organisms face stressful situations and use endocrine mechanisms, such as glucocorticoid production, to maintain homeostasis. Although glucocorticoids are essential for basal function, their secretion increases when organisms face stressful situations.

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 ...
