Thrombocyte indices; plateletcrite, mean platelet volume and platelet distribution width in dogs infected with ehrlichia canis and anaplasma phagocytophilum.

In the present study alterations in trombocyte numbers and trombocyte indices were investigated in 51 dogs naturally infected with E. canis and/or A. phagocytophilum. Achieved results were compared to those of 20 healty dogs comprising control group. Complete blood count and trombocyte indices were analyzed in Abacus Junior cell counter.The predominant findings in dogs infected with E. canis and/or A. phagocytophilum were nasal discharge, decreased appatie, weight loss, tick infestation and lymphadenopathy and those aforementioned signs showed statistical differences (p?0,01) in conrast to healty dogs involved in control group.Mean PLT counts were significantly decreased in II. (A. phagocytophilum), III. (E. canis+ A. phagocytophilum) and IV. (E. canis) groups (159,6±63,5, 142,3±44,3, 148,7±33,5, respectively) in comprasion to control group (370,4±28,6) (p?0,01).Mean PCT values in groups II., III. and IV. (0,1530±0,590, 0,1531±0,0441, 0,1450±0,314, respectively) were significantly decreased in contrast to control group (0,3695±0,0283) (p?0,01).Between PLT and PCT values, statistically significant positive correlation (p?0,01) (r=0,988, 0,990 ve 0,981, respectively ) was evident among groups II., III. and IV.In conclusion, regarding to the data achieved from the present study, it may be suggested that in dogs infected with E. canis and/or A. phagocytophilum, RBC and PLT indices should interpreted along, in an attempt to scrutinize anemia and/or trombocytopenia. Infected dogs showed significant alterations (p?0,01) among mean PLT and PCT values and a positive correlation was evident between those 2 parameters (p?0,01), where as alterations on mean MPV and PDWc were not statistically significant.Finally it was suggested that according to the aforimentioned results, PLT and PCT values may be used as valuable parameters for diagnosis and probably for monitorization and prognosis in infected dogs with mentioned agents.
