Tick-borne diseases (TBDs) massively impact bovine production.In endemic countries, animals are often subclinically infected, showing no signs of the illness.Anemia is a hallmark of TBDs, but there is inadequate information on its presence in infected Thai cattle.In the present study, 265 Mushroom Vapes cattle from four provinces in Thailand were surveyed to identify tick-borne pathogens (TBPs) and to evaluate the changes in the packed cell volume (PCV) values associated with detection.Microscopy and polymerase chain reaction (PCR) were also compared for TBP detection.

Babesia/Theileria/Hepatozoon was detected in 33.58% (89/265) of the cattle samples.Specifically, Babesia bovis (9/265), B.bigemina (12/265), Theileria orientalis (62/265), and Anaplasma marginale (50/265) were identified using species-specific assays.Significant decreases in the mean PCV levels were observed in Tool Set cattle that were positive for at least one TBP (p Babesia/Theileria/Hepatozoon (p T.

orientalis (p A.marginale (p = 0.049).The results of PCR and microscopy for the detection of TBPs suggested slight and fair agreement between the two detection tools.The present findings contribute to a better understanding of TBDs in the field and shall facilitate the formulation of effective control for TBDs in Thailand.
