A retrospective study was conducted to provide an update of the current status of important blood protozoan infections in ruminant livestock in Malaysia from January 2011 to December 2017.  A total of 10,258 blood samples were examined for the presence of blood protozoan parasites, of which 4022 samples were from goats, 2820 from cattle, 1665 from deer, 1348 from sheep and 403 from buffaloes.  The blood samples were submitted to the Veterinary Research Institute (VRI) Ipoh, Perak, from various farms in Peninsular Malaysia. Thin blood smear and Giemsa staining was carried out on each of these blood samples to confirm the presence of blood protozoan parasites.  Out of 10,258 blood samples examined, 966 (9.42%) were found positive for blood protozoan infections. A total of 40.3% of all samples with Theileria spp. was found in samples of cattle and buffaloes, followed by 51.6% of all samples with Trypanosoma spp. was found in deer samples.  Meanwhile, Babesia spp., Anaplasma spp. and Eperythrozoon spp. were also found (0.72% in all ruminant species).  A prevalence study on ruminant livestock should be carried out to estimate the importance of protozoan infections towards the mortality and morbidity of food animals.   As such, the use of current methodologies such as serological or molecular methods is required to obtain a more accurate picture of the common species of blood protozoan parasites available in Malaysia. Thus, control and prevention strategies can be carried out more effectively to ensure that healthy animals will contribute to the healthy society.
