Abstract: A novel use of P44 as a marker for predicting or diagnosing anaplasmosis including a diagnostic composition and a diagnostic kit is disclosed. A diagnostic composition for anaplasmosis containing a P44 gene, a primer set or probe for detecting Anaplasma phagocytophilum, a kit for diagnosing anaplasmosis, and a method for providing information to diagnose infection with Anaplasma phagocytophilum are also disclosed. P44, which is a novel biomarker for diagnosing anaplasmosis, is a multi-copy gene and exists in a large number of copies in the Anaplasma phagocytophilum genome, thus having the effect of detecting Anaplasma phagocytophilum infection at high sensitivity using only a small amount of DNA compared to conventional diagnostic marker genes. In addition, the primer set or probe for detecting and amplifying P44 is capable of providing rapid and easy detection of anaplasmosis with high specificity and sensitivity, making it appropriate for early detection of anaplasmosis.
