|
Physiologic Leukocytosis
|
Young, excited fearful animals
Mild neutrophilia wo left shift Mild lymphocytosis uncommon in k9, common in cats and horses caused by stress |
|
Stress Leukocytosis
|
corticosteroid therapy
stress, pain, extreme change in temp. neutrophilia wo left shift lymphocytopenia eosinopenia +-monocytosis more common in cats than dogs |
|
Inflammatory Leukocytosis
|
infections
neutrophilia w/ left shift bacterial, protzoal, fungal and viral infections degree of neutrophilia; localized pus has greater response than pyo |

|
Neutrophils
|
Phagocytic - engulf and destroy bacteria and other particles
survives up to 10 hrs in blood;1 day in tissues cells more immature than myleocytes are unable to engulf partical matter |
|
Lymphocytes - 2 types
|
gut-associated - plasma cells
produce antibodies thymic-associated - cellular immunity responsible for graft rejection and hypersenstivity reaction |
