3.1. Detection and intensity of H. columbae infection

Haemosporidian infection was detected in 24 of 87 wild pigeons ( C. livia ) by both microscopic and molecular examinations. The positive infection rates at the Nakhon Sawan and Phitsanulok test sites were 22% (11/50) and 35% (13/37), respectively. The overall infection rate was approximately 27.6% (24/87). All positive samples underwent successful amplification of the partial cyt b gene. The obtained sequences were deposited in GenBank under accession numbers ON411230–ON411253. The intensity of haemosporidian infection was very low (approximately 0.028%; Table 1). The BLASTn results indicated 100% identity with one of the three common H. columbae lineages, namely HAECOL1, COLIV03, and COQUI05. HAECOL1 had a higher

positive rate (18.4%) than COLIV03 and COQUI05, which had minor positive rates (4.6%).
