Equine piroplasmosis (EP) is global disease of equids affect the international
movement of horses and their industry. This work was conducted on a random collection of
blood samples from a total of 306 equids (horses and ponies) comprising both clinically
healthy (n=276) and clinically suspected animals (n=30) for EP from 53 stables in eight
districts at Kelantan, Malaysia. Competitive-inhibition enzyme linked immunosorbent test
(cELISA) was applied to detect the antibodies for Theileria equi and Babesia caballi and their
titers in the serum. Hemato-biochemical parameters were analyzed from blood and serum
samples from clinical and subclinical cases in comparison to healthy animals (n=25) a control
group. The overall prevalence of EP infections (T. equi, B. caballi and both infections) in
subclinical and clinical infected equids was 70.26 and 9.80 per cent, respectively. The
subclinical infection in equids was statistically higher than that of clinical infection (P
