Article Synopsis
- Crocodilians exhibit exceptional health and resilience to infections due to highly active immune mechanisms and superior plasma hemolytic capacity, despite regular exposure to harmful microorganisms.
- Several host defense peptides (HDPs) such as cathelicidins and beta-defensins have been identified in these animals, demonstrating effective antimicrobial, antifungal, and anticancer properties.
- The study of these peptides provides insights into immune defense mechanisms that are conserved across many species and opens up possibilities for developing new therapeutics to address the growing issue of antimicrobial resistance in modern medicine.
Article Synopsis
- Human interactions with crocodilians date back to early settlements, but increasing threats like habitat loss and pollution have pushed many species to near extinction.
- Strategies such as reintroducing and head-starting programs aim to recover crocodilian populations, while involving local communities has shown to aid in their recovery without harming biodiversity.
- The Proyecto Yacaré initiative was established to manage and restore the critically endangered broad-snouted caiman through sustainable practices that balance conservation and local economic benefits.
Immuno-endocrine alterations and oxidative stress induced by commercial formulations of pesticides in the tegu lizard (Salvator merianae).
Environ Toxicol Pharmacol
October 2023
Recent research has shown the risk of environmental contamination by pesticides in Argentina. Salvator merianae is considered as "sentinel species" for monitoring their effects. We intended to investigate growth, immunological and endocrine functions, and oxidative stress in S.

- Plasma biochemistry values are essential for assessing the nutritional and physiological health of animals, especially under environmental stress.
- This study is the first to use micro-volume plasma tests to measure total plasma protein, albumin, and glucose levels in juvenile Caiman latirostris, comparing these results to existing crocodilian data.
- Caimans exposed to heat treatment exhibited increased weight, length, and glucose levels, while food-restricted caimans showed less growth and significantly lower albumin levels, with no notable differences in water-restricted groups compared to controls.
Effects of glyphosate, cypermethrin, and chlorpyrifos on hematological parameters of the tegu lizard (Salvator merianae) in different embryo stages.
Chemosphere
August 2020
Different studies have demonstrated effects of pesticides during embryo development in vertebrates and stage-dependent effects, but there is no information concerning this for Salvator merianae. We evaluated the effects of the herbicides Glyphosate Roundup (GLY-RU) and Glyphosate Panzer Gold (GLY-PZ); and the insecticides Chlorpyrifos (CPF) and Cypermethrin (CYP), and their complex mixtures, at different concentrations in hematological parameters of S. merianae embryos at two different development stages.

Particularly in Santa Fe province, the area occupied by populations of these lizards overlaps with areas where agriculture was extended.

Many vertebrates require ultraviolet (UV) radiation to perform different physiological processes. Artificial light is used to supplement UV in captive animals, through appropriate photoperiods and UV wavelengths.
