ABSTRACT
Background:
Anaplasma phagocytophilum is an obligate intracellular pathogen transmitted by the ticks that cause equinegranulocytic anaplasmosis (EGA). This pathogen is infects predominantly blood cells, principally granulocytes and especially neutrophils. A. phagocytophilum causes an acute febrile disease in horses accompanying with lethargy, loss ofappetite, lameness and hemorrhages. In horses, this disease should be considered in all acute symptoms accompaniedby thrombocytopenia and leukopenia identified by hematological test performed. Tick-borne pathogens have becomeincreasingly threatening for both animals and also public health since ticks mostly carry numerous well-documented andundocumented pathogens, and the geographical range of ticks has expanded in the recent years. This research has aimed toevaluate the impact of A. phagocytophilum infection on some oxidative/nitrosative stress parameters, antioxidant enzymeactivities, proinflammatory biomarkers and trace element levels in horses.Materials, Methods &Results:
The present study has been carried out using blood samples collected from 93 horses aged1-year and older. The blood samples were centrifuged and sera were separated. Serum samples stored in the freezer (-20°C)until the day of analysis. The DNA was extracted from blood and analysed by nested-PCR technique targeting 16S rRNAgene of A. phagocytophilum and then positive PCR products were sequenced. A. phagocytophilum was 6 horses (6.4%)showed positive nested-PCR results. An infected group comprised of 6 positive horses according to PCR analysis results also6 healthy horses as control were selected. Serum SOD (Horse Superoxide Dismutase(Cu-Zn)) ELISA Kit, MPO (ELISAAssay Kit Horse Myeloperoxidase) and GPx (Horse glutathione peroxidase 1 ELISA Kit Assay), IL1 (Horse Interleukin 1Beta ELISA Kit), IL6 (Horse Interleukin 6 ELISA Kit), TNF α (Horse Tumor Necrosis...Palavras-chave
