Which organ is MOST affected by leptospirosis?

Leptospirosis primarily impacts the kidneys, making them the organ most affected by this bacterial infection. The Leptospira bacteria can cause inflammation and damage within the renal tubules, leading to renal impairment. The kidneys are critical for filtering waste from the blood and maintaining electrolyte balance, and their dysfunction can result in severe consequences for an animal's overall health.

In addition to the kidneys, leptospirosis can have systemic effects that may involve other organs, but the kidneys remain the most significantly affected. This is especially crucial in veterinary practice, as the recognition and treatment of leptospirosis need to focus on renal health and function. Addressing these issues promptly can help mitigate complications and support recovery in affected animals.
