The objective of this study was to describe the hematological and biochemical complications in cattle of southwestern Paraná region infected with Anaplasma, comparing these changes with the parameters presented by healthy cattle from the same region. We evaluated 40 cows with milk aptitude, 20 clinically suspected of being infected by the parasite and other 20 healthy, which served as a control group. Blood counts were performed in automated hematology counter. For the differential white cell count and agent search was held smears. Albumin analysis, total protein (TP), urea, creatinine, aspartate-aminotransferase and serum gamma-glutamyl transferase were carried out in semi-automatic biochemical analyzer. The results were evaluated using SPSS, version 20.0, and submitted to the Student t test. The diagnosis was made by identifying the hemoparasite in blood smears. Infected mice had a parasitemia ranging from 11 to 20%. We found statistically significant differences (p < 0.01) among the following hematocrit of infected (17,99±1,49%) and healthy controls (29,38±0,96%); number of red blood cells infected (3,71±0,39x106/ L) and healthy controls (7,23±0,37x106/L); of infected hemoglobin (6,08±0,65g/dL) and healthy controls (9,96±0,33g/dL); VCM infected (52,60±3,07fL) and healthy controls (41,34±1,31fL); of infected monocytes (1353,27±373,61/L) and healthy controls (517,84±113,22/μL); PT (total protein) of infected (7,60±0,18g/dL) and healthy controls (5,90±0,28g/dL). Infected animals showed marked anemia and serum increase in PT. We conclude that these blood parasites cause monocytosis and severe clinical signs resulting from severe anemia, but do not alter markers of liver and renal function of cattle in the clinical form of Anaplasmosis.(AU)
