Abstract: Anaplasmosis is a vector borne disease that affects animals and human worldwide. These parasites parasitize erythrocytes, monocytes, granulocytes, and platelets. Members of the family Anaplasmataceae are obligate intra cellular gram-negative bacteria. A Labrador male dog aged about six years and admitted in a private veterinary clinic in Jaipur with the clinical signs of anorexia for a period of two months, lethargy, lameness while walking in both hind legs, anemia intermittent temperature. The dog was infested with ixodes ticks. The blood smears examination of the dog revealed A. phagocytophilum in neutrophils and A. platys in the platelets, which indicates the co-infection state of both the organisms in one infected dog. The hematological parameters revealed Hb-11.7 g/dl, TLC- 5.6 thou/cu.mm, lymphocytes- 33%, RBC- 5.34 mil;l/mm³, PCV- 34.9% & platelet- 80 thou/mm³. The biochemical values revealed changes in the SGPT level of 103.60 u/l which is a high value indicated the liver enzyme dysfunction. An elevated alkaline phosphatase level i.e. 370.30 u/l was observed in this case. The other biochemical parameters were within the normal range. Overall hematology and biochemical values revealed the anemia, leucopenia, lymphocytopenia, thrombocytopenia, elevated SGPT (ALT) & Alkaline phosphate levels before treatment. It is confirmed that as with A. phagocytophilum infection, animals with clinical disease resulting from A. platys infection respond rapidly to treatment with tetracycline. The haemogram studies revealed normal values after the treatment with oxytetracycline with scanty prevalence of the A. phagocytophilum and Anaplasma platys in blood smear examination. This study confirms the concomitant infection of A. phagocytophilum and Anaplasma platys in the Labrador dog.
