| − | ==Eosinophilia==
| |
| − | | |
| − | * Eosinophilia an increase in numbers of eosinophils in the blood/tissues
| |
| − | | |
| − | * Occurs in:
| |
| − | ** Parasitism or hypersensitivity.
| |
| − | *** The antigens of both may sensitise T-lymphocytes, and re-exposure to the agent may result in quite substantial numbers of eosinophils.
| |
| − | ** Some breeds of dogs, e.g. German Shepherd.
| |
| − | | |
| − | *** Are prone to developing eosinophilia.
| |
| − | [[Category:Inflammation]][[Category:To Do - Blood]]
| |
| − | ==Eosinopenia==
| |
| − | | |
| − | * Eosinopenia is a reduction in the number of eosinophils in the blood.
| |
| − | | |
| − | * Occurs as part of the response to corticosteroids;.
| |
| − | ** Thought to be associated with the depressive effect of corticosteroids on lymphocytes.
| |
| − | | |
| − | *** Secretions of these lymphocytes are thought to stimulate eosinophil production.
| |
| − | [[Category:Inflammation]][[Category:To Do - Blood]]
| |
| − | ==Lymphocytosis==
| |
| − | | |
| − | * Lymphocytosis is an increase in numbers of lymphocytes in the blood.
| |
| − | | |
| − | * Occurs:
| |
| − | ** In tumours in which there is a substantial increase in their number.
| |
| − | *** Some of the lymphocytes are immature - lymphoblasts.
| |
| − | *** For example, Bovine Leukosis.
| |
| − | ** Following adrenaline release in fear, excitement and so on.
| |
| − | ** In some cases of chronic infection.
| |
| − | *** However, reactive hyperplasia in associated lymph nodes may not correlate with the numbers of circulating lymphocytes.
| |
| − | ** Commonly in growing swine.
| |
| − | | |
| − | *** Possibly associated with aMycoplasma infection.

| |
| − | ==Lymphopenia==
| |
| − | | |
| − | * Lymphopenia is a redcution in the numbers of lymphocytes in the blood.
| |
| − | | |
| − | * Occurs in:
| |
| − | ** Viruses that attack the lymphoid system.
| |
| − | *** For example:
| |
| − | **** [[Paramyxoviridae#Canine Distemper Virus (CDV)|Canine Distemper]]
| |
| − | **** Infectious Canine Hepatitis
| |
| − | **** Feline Infectious Enteritis
| |
| − | **** Bovine Virus Diarrhoea.
| |
| − | ** Irradiation
| |
| − | ** Corticosteroid therapy.
| |
| − | *** Selectively suppresses lymphocytic activity, and the inflammatory response in general.
| |
| − | | |
| − | *** Other immunosuppressive drugs may act in a similar way.

| |
| − | ==Plasma Cells in Blood==
| |
| − | | |
| − | * Plasma cells are rarely observed in blood.
| |
| − | | |
| − | | |
| − | * If many plasma cells are present in blood, it is due to a plasma cell tumour that has begun to metastasise.
| |
| − | [[Category:Inflammation]][[Category:To Do - Blood]]
| |
| − | ==Monocytosis==
| |
| − | | |
| − | * Monocytosis -is an increase in numbers of [[Monocytes|monocytes]] (haematogenous macrophages) in the blood.
| |
| − | | |
| − | * Occurs:
| |
| − | ** In conjunction with neutrophilia in fear, excitement etc.
| |
| − | ** In the chronic stages of bacterial disease.
| |
| − | * Monocytes very rarely behave as macrophages in the blood.
| |
| − | | |
| − | ** However, this is seen in cases of severe intravascular haemolysis of red blood cells where remnants of the RBC's are found in their cytoplasm.
