What is "nephritis" characterized by?

Nephritis is specifically characterized by inflammation of the kidneys. This condition can arise from various causes, such as infections, autoimmune disorders, or toxins. The inflammation can lead to symptoms such as pain in the lower back, changes in urine production, and sometimes systemic symptoms like fever or malaise. Understanding nephritis is critical in veterinary medicine as it can significantly affect the overall health of an animal and requires timely diagnosis and treatment to prevent further complications or damage to the renal system. The other conditions mentioned do not pertain to nephritis as they refer to inflammation of different organs, which helps further clarify the unique nature of nephritis.
