What are eosinophils in a cat? - briefly
Eosinophils in a cat are a type of white blood cell that primarily respond to parasitic infections, allergies, and certain inflammatory conditions.
What are eosinophils in a cat? - in detail
Eosinophils are a type of white blood cell that form an essential part of the feline immune system. They are produced in the bone marrow and circulate in the bloodstream, playing a significant role in defending the body against parasitic infections and modulating allergic reactions. Eosinophils contain granules filled with proteins and enzymes, such as eosinophil peroxidase and major basic protein, which are released to combat invading pathogens, particularly parasites like worms and certain protozoa. These cells are also involved in the inflammatory response, particularly in conditions related to allergies, asthma, or hypersensitivity reactions. In cats, elevated levels of eosinophils, known as eosinophilia, can indicate underlying health issues such as parasitic infestations, allergic dermatitis, asthma, or even certain types of cancer like eosinophilic granuloma complex. Conversely, low levels of eosinophils, or eosinopenia, may occur during stress or as a result of certain medications, such as corticosteroids. Veterinarians often assess eosinophil counts through a complete blood count (CBC) to diagnose and monitor these conditions. Understanding the behavior and function of eosinophils in cats is crucial for identifying and managing various diseases, ensuring the overall health and well-being of the animal.
