Results of hematologic analyses and prevalence of physiologic leukopenia in Belgian Tervuren.

摘要

Blood samples from 180 healthy Belgian Tervuren and 63 healthy dogs of other breeds were analysed by use of an automated device. Reference ranges were calculated for Belgian Tervuren by use of standard methods. Total leukocyte counts of Belgian Tervuren ranged from 2.61 to 16.90 X 103/鎙. Mean leukocyte count of Belgian Tervuren (mean±SEM, 7.04±0.16X103/鎙) was significantly lower than mean count for control dogs. Significantly more Belgian Tervuren (65/180, 36%) than control dogs (2/63; 3%) had leukocyte counts <6.00 X 103/鎙. Percentage of Belgian Tervuren with leukocyte count <6.00 X 103/鎙 was low for dogs <=2 years old, increased sharply for dogs between 2 and 4 years old, and was approximately 65% for dogs >4 years old. Neutrophil, lymphocyteand monocyte counts were significantly lower, and erythrocyte count, haematocrit and eosinophil fraction were significantly higher in Belgian Tervuren than in control dogs. It is suggested that physiological leukopenia, resulting from low numbers of neutrophils, lymphocytes and monocytes, may be a typical finding in a large percentage of healthy Belgian Tervuren and is not of clinical importance in otherwise healthy dogs. Healthy Belgian Tervuren may also have erythrocyte counts and haematocrits higherthan expected for healthy dogs.
