Clinico-Pathological Investigation and Management of Babesiosis in Kankrej cattle.
Babesiosis is an important tick borne protozoan infection caused by the genus Babesia which is clinically characterized by high fever, inappetence, emaciation, anemia, jaundice and hemoglobinuria, occasionally diarrhea and abortion may occur in pregnant cattle (Salem et al., 2016). The infection leads to huge loss of production and occasional mortality (Banerjee et al., 2005). Bovine babesiosis is very well known to cause anemia of various type viz. hemolytic, hypochromic as well as normochromic, this change is associated with reduction in erythrogram parameters as well as alterations in serum biochemical parameters (Sharma et al., 2016).The study describes the clinical, hematological and biochemical observations in Babesia infected Kankrej cattle with successful therapeutic management.
History and Clinical Observations
The present study includes total eight Kankrej cattle (5 cows and 3 bullock) aged eight to twelve years with history of hemoglobinuria, inappetence and high fever. Clinical examination revealed high rectal temperature (103.2[degrees]F-104.3[degrees]F), ruminal atony, swollen lymph nodes, pale pink to pale conjunctival mucous membrane, tachycardia, tachypnea and mild to moderate tick infestations.
Thin blood smears were prepared from ear vein of all animals and stained with Giemsa stain to observe under light microscope for presence of intraerythrocytic stages of hemoparasite. Blood samples were collected from jugular vein into [K.sub.3]EDTA-vacutainers for determination of hematological parameters using automatic blood analyzer and Clot activator-vacutainers to determine serum biochemical parameters using semi-automatic clinical chemistry serum analyzer. The blood glucose was estimated by automatic glucometer.
Diagnosis and Treatment
The pyriform bodies of Babesia organism was observed in thin blood smear (Fig. 1). The hemato-biochemical alteration were also recorded in Table-1. All animals were treated with Inj. Nilbery (a) (Diminazine diaceturate) @ 3.5 mg/kg b.wt. intramuscularly at two different site in neck muscles along with supportive therapy including Inj. Melonex (a) (Meloxicam) @ 0.5 mg/kg, Inj. Tribivet (a) (Vit [B.sub.1], [B.sub.6] and [B.sub.12]) @ 10 ml, Inj. Anistamin (a) (Chlorpheni-ramine maleate) @ 10 ml and Inj. Feritas (a) (Iron Sorbitol citric acid complex, Folic acid and Hydroxycobalmin) @ 10 ml intramuscularly on day one. After 12 hours of treatment and by the end of 24 hours, the color of urine was almost normal in color and appetite was partially restored so supportive treatment with Inj. Intalyte (a) (20 percent Dextrose and Electrolytes) @ 2 lit I/V, Inj. Tribivet (a) @ 10 ml I/V as well as Inj. Anistamin (a) @ 10 ml and Inj. Melonex (a) @ 0.5 mg/kg intramuscularly was continued for three days while Bolus Feritas (a) @ 2 boli BID and Liq. Amblycure D.S. (b) (Liver tonic) @ 50 ml BID were given till complete recovery.
The tick-borne infection leads to negative impact on livestock health as well as great economic losses. The light microscopy examination for detection of Babesia piroplasms is relatively cheap, quick and gold standard method even though for chronic infection. The clinical signs including high fever, loss of appetite, anemia, hemoglobinuria, pale mucus membranes and suspended rumination which are in support with Constable et al. (2017).
The lower level of hemoglobin, TEC, PCV, MCHC and platelets along with increase in MCV value in infected animals advocates presence of macrocytic hypochromic anemia. Anemia is an important feature of Babesia because the presence of protozoa lead to destruction of RBCs and creating hemolysis (Kakoma and Ristic, 1984). The low values of platelets count is due to lower production or high destruction which is usually correlated with immune-mediated process and hemolysis (Riond et al., 2008). However, leukocytosis, monocytosis and lymphocytosis in clinically infected animals which is close to Salem and El-Sherif (2015). This is because of RBC destruction by Babesia spp. stimulates phagocytic activity of lymphocytes and monocytes to clean up the body from toxic remnants of ruptured red blood cells which is explained by Guglielmone et al. (1996) that Babesia infection stimulates the body defense mechanism for production of antibodies.
The present investigation exhibited hypoglycemia, higher level of AST, hypoproteinemia, hypoalbuminemia, hyperglobulinemia and increased values of creatinine and BUN in Babesia infected animals. The harmful effect of toxic metabolites of Babesia spp. on liver cells leading to higher level of AST, hypoproteinemia and hypoalbuminemia (Yeruham et al., 2003) while on renal tissue causing impairment and alterations of the kidney enzymes viz. creatinine and BUN and hemoglobinuric nephrosis (Sharma et al., 2016). The significant increase in serum globulins in present study could be attributed to immune response against Babesia and hypoglycemia is associated with anorexia as suggested by Fujinaga (1981). Diminazine diaceturate acts by blocking the replication of DNA of the parasite which has been reported to be highly effective drug against babesiosis (Kumar et al., 2008). The present study suggested that early detection as well as specific chemotherapy and intensive supportive therapy are essential for successful management of babesiosis in Kankrej cattle.
