In this chapter, we describe that naturally infected dogs with Anaplasmataceae show altered rhreological parameters. Also, we have showed that lower viscosity correlated with the lower erythrocyte number and release of IFN-γ. The rheometry of the fresh blood samples was measured by using the Modular Compact Rheometer—MCR 102 (Anton Paar® GmbH, Ostfildern, Germany), and the graphs were obtained using Rheoplus software. Blood count data were obtained by analysis in a private laboratory. Diagnostic confirmation was obtained by molecular PCR technique that was used to determine the groups of not infected and infected by Anaplasmataceae. Serum cytokines were dosed by flow cytometry (FACScalibur BD®) using BD® Biosciences Cytometric Bead Array (CBA) Human Th1/Th2/Th17 Cytokine kits. The results showed a correlation between blood viscosity (p < 0.05, r = 0.73) and shear rate (p < 0.05; r = −0.676) with IFN-γ in the group of infected dogs that presented anemia, as well as correlations of shear rate with erythrocytes (p < 0.05; r = −0.88). Thus, IFN-γ appears to play an important role in the immunomodulation of the rheological behavior of naturally infected dogs to Anaplasmataceae. The alterations in cytokines profile and their relationship with blood viscosity and hematological parameters was related in this study the first time of dogs naturally infected with Anaplasmataceae.
