What is the medical term for a decreased level of neutrophils?

The term for a decreased level of neutrophils is indeed neutropenia. Neutrophils are a type of white blood cell that plays a crucial role in the immune response, particularly in fighting infections. When the number of these cells is lower than normal, the body may have an increased susceptibility to infections, as neutrophils are vital for responding to bacterial infections.

Neutropenia can arise from various causes, including bone marrow disorders, autoimmune diseases, certain medications, and nutritional deficiencies. Recognizing this condition is important for veterinary professionals to ensure proper diagnosis and treatment for affected animals.

The other terms listed do not describe a decrease in neutrophils. Neutrophilia refers to an increased number of neutrophils, indicating a possible infection or inflammation. Neutrocytosis is a less commonly used term that can also refer to an increase in neutrophil levels. Neutrosuppression is a more general term that could refer to a reduction in neutrophil function or activity rather than their quantity. Understanding the implications of neutropenia is key in clinical veterinary settings.
