What disease or condition may be caused by stress due to shipment in frogs?

• A. Cutaneous capillariasis
• B. Mycobacteriosis
• C. Red leg
• D. Gas bubble disease

Answer: (C)

Stress during shipment weakens frogs’ immune defenses and disrupts their skin barrier, making them more susceptible to opportunistic bacterial infections. Red leg syndrome is the visible sign of this, typically showing reddened limbs or ventral skin along with lethargy or lethargic behavior and sometimes ulcers, caused by septicemia from bacteria such as Aeromonas hydrophila in stressed animals. The other conditions aren’t commonly linked to transport stress in frogs: cutaneous capillariasis is a nematode infection of the skin, mycobacteriosis is a chronic granulomatous disease, and gas bubble disease relates to gas embolism in fish from water supersaturation. To prevent red leg, ensure gentle handling, stable temperature and water quality, proper packing, and minimize transport stress.
