Clinicopatho-Biochemical Alterations Associated with Subclinical Babesiosis in Dairy Animals.
BACKGROUND
Present investigation is based on the clinicopatho-biochemical alteration related to natural tick borne bovine babesiosis in Punjab state.


METHODS
Blood samples from jugular vein of 542 bovines (cattle 466 and buffaloes 76) having history of tick infestation, fever, hemoglobinurea or anemia were collected and tested for Babesia bigemina by blood smear examination and PCR targeting 18S rRNA gene to distinguish clinically and subclinically infected groups. Further the hemato-biochemical parameters were correlated with the status of infection.


RESULTS
Overall, of the 542 samples tested 16.42 % were positive by PCR while only 1.66 % by blood smear examination. The trend of molecular prevalence was found to decrease from north-eastern towards western Punjab. Analysis of the hematobiochemical alterations showed significant decrease in the levels of RBC, Hb, PCV, and MCV with significant increase in TBIL, MCH and MCHC levels.


CONCLUSIONS
As the transmission of B. bigemina is transovarian, presence of even few infected Rhipicephalus (Boophilus) microplus ticks on a subclinically infection can be the nidus of infection for whole herd, causing severe economic losses, at the same time significantly affecting the physiology of carrier animal.
