| leukocytopenia | Abnormal decrease in the number of leukocytes in the blood (white blood cells that help to combat infection). (16 Dec 1997) |
| leukocytoplania | Movement of leukocytes from the lumens of blood vessels, through serous membranes, or in the tissues. Origin: Leukocyte + G. Plane, a wandering (05 Mar 2000) |

| leukocytosis | A term used to describe an abnormal elevation on the white blood cell count. Normal white blood cell counts are variable with age and sex. Normal adult range is 4, 500 to 11,000 cells per cubic millimetre of blood. Slightly higher counts are seen in children. Elevated counts can be seen in cases of inflammation and infection. (27 Sep 1997) |
| leukocytosis of the newborn | An apparently "physiologic" leukocytosis usually observed in newborn infants, in whom the white blood cell counts are usually greater than 10,000 per cu mm, and sometimes range to 45,000 per cu mm, resulting chiefly from increased numbers of neutrophils (especially single and bilobed forms). On the third or fourth day of life, the count generally decreases rapidly, and then fluctuates for several days; beginning about the fourth week of life, a relative lymphocytosis is observed, and this normally continues for a few years. (05 Mar 2000) |
| leukocytosis-promoting factor | A substance obtained by Menkin from inflammatory exudates; it stimulates leukocytosis. (05 Mar 2000) |
| leukocytotactic | Pertaining to, characterised by, or causing leukocytotaxia. Synonym: leukocytactic, leukotactic. (05 Mar 2000) |
| leukocytotaxia | 1. The active ameboid movement of leukocytes, especially the neutrophilic granulocytes, either toward (positive leukocytotaxia) or away from (negative leukocytotaxia) certain microorganisms as well as various substances frequently formed in inflamed tissue. 2. The property of attracting or repelling leukocytes. Synonym: leukocytaxia, leukocytaxis, leukotaxia, leukotaxis. Origin: Leukocyte + G. Taxis, arrangement (05 Mar 2000) |
| leukocytotoxin | Any substance that causes degeneration and necrosis of leukocytes, including leukolysin and leukocidin. Synonym: leukotoxin. Origin: Leukocyte + G. Toxikon, poison (05 Mar 2000) |
| Leukocytozoon | A genus of sporozoan parasites (family Plasmodiidae, suborder Haemosporina) that attack the immature red blood cells of birds and are capable of causing acute outbreaks of disease, particularly in turkeys and ducks; vectors are black flies, Simulium species, and the bloodsucking gnat Culicoides. Synonym: Leukocytozoon. Origin: G. Leukos, white, + kytos, cell, + zoon, animal (05 Mar 2000) |
| leukocytozoonosis | Infection of ducks, turkeys, chickens, pigeons, and doves with species of the protozoan genus Leucocytozoon. The disease is most acute and damaging in young turkeys and ducks, and is characterised by enlargement of the spleen and liver, anaemia, listlessness, weakness, and frequently death. Synonym: leukocytozoonosis. (05 Mar 2000) |
