Amphibian Stress Linked to Increased Susceptibility to Skin Infections
Amphibians, including frogs, toads, and salamanders, are experiencing increased susceptibility to skin infections due to stress factors such as poor husbandry, transport, and overcrowding. These stressors weaken their innate immune responses, which are heavily temperature-dependent. Amphibians have a unique integumentary system with thin, moist, and richly vascularized skin, making them vulnerable to environmental contaminants and infectious agents. A common fungal infection affecting amphibians is chytridiomycosis, caused by Batrachochytrium dendrobatidis (Bd), which leads to symptoms like excessive skin shedding, lethargy, and erythema of the ventral skin. Treatment involves antifungal therapy and improving husbandry conditions to reduce stress.
