Hipoplasia neutrofílica seletiva em cadela da raça maltês: relato de caso

Abstract

In the bone marrow are the pluripotent progenitor cells that give rise to the cells that make up the blood, among them the set of cells that make up the immune system. Neutrophils are granulocytes considered to be the body's main line of defense against invading agents. A disorder promoting a decrease in the production of these cells, with consequent immunosuppression, makes the animal susceptible to diseases. Medullary hypoplasia is a condition that affects the bone marrow, affecting the production and assembly of the cells that make up the blood system, and can compromise the production of cells of the erythroid, leukocytic, and megaryocytic series. Granulocytic hypoplasia is determined by a decrease in neutrophils in peripheral blood and bone marrow. It can be the consequence of multiple causes and has no specific treatment using hematopoietic stimulants as an ally. The diagnosis is made through cytology and bone marrow biopsy, in addition to complementary exams that can help discover the possible cause. The present work, consisting of a case report, has as objective to describe the clinical attendance of a female dog attended in the Veterinary Hospital of the Federal University of Paraíba, Campus II, in the city of Areia-PB, she underwent laboratory and hematological examinations in addition to serial blood counts in order to find the cause of persistent leukopenia and neutropenia without clinical manifestations. After of aspiration puncture, the patient was diagnosed with Neutrophilic Granulocytic Hypoplasia.
