Clinicopathological alterations in naturally occurring Babesia gibsoni infection in dogs of Middle-South Gujarat, India
Abstract
Aim: The present research work was undertaken to describe various clinical signs and hematobiochemical alterations in dogs affected with Babesia gibsoni. Materials and Methods: Blood smears from a total of 79 suspected dogs of Anand region as well as Surat region of Gujarat state (India) were screened for detection of intraerythrocytic piroplasm of small form of Babesia. Diagnosis was made on the basis of clinical signs and demonstration of B. gibsoni organism in Giemsa-stained thin blood smears. The clinical signs were recorded at the time of presentation, and blood samples were subjected to estimation of hematobiochemical parameters by auto hematology analyzers at College of Veterinary Science and Animal Husbandry, Anand. Statistical analysis, interpretation, and comparison of hematobiochemical changes with scientific literature were carried out to understand the pathophysiology of the disease. Results: Out of 79 dogs, 16 were positive for naturally occurring babesiosis based on the presence of intraerythrocytic piroplasm of small form of Babesia in blood smears. The clinical cases were manifested by wide variety of non-specific clinical signs. The hematological evaluation revealed that the mean values of hemoglobin and total erythrocyte counts in dogs with babesiosis decreased significantly (p<0.01) in comparison to healthy dogs. Among differential leukocyte count, mean values of neutrophils and eosinophils increased while lymphocytes decreased (p<0.01) in dogs with babesiosis in comparison to healthy dogs. Serum biochemistry revealed increase (p<0.01) value of alkaline phosphatase, alanine aminotransferase, aspartate aminotransferase, and globulin as well as decrease in albumin levels (p<0.05) in dogs with babesiosis as compared to healthy dogs. Conclusion: B. gibsoni is having multisystemic effects with atypical hematobiochemical changes in dog are discussed here, which would aid new insights in diagnosis of disease.
