Leptospirosis

A bacterial disease spread through contaminated urine, affecting multiple organs and transmissible to humans.

Detailed explanation

Leptospirosis is a serious bacterial disease caused by spiral-shaped bacteria called Leptospira. It is a zoonotic disease, meaning it can be transmitted from animals to humans. Pets become infected through contact with urine from infected wildlife (like raccoons, skunks, deer, rats), contaminated water sources (puddles, ponds, slow-moving streams), or soil. The bacteria enter the body through mucous membranes or breaks in the skin. Leptospirosis can cause kidney damage, liver failure, and bleeding disorders. Symptoms vary widely and can be severe. Treatment involves antibiotics and supportive care. Vaccination is available for dogs at high risk of exposure.
