ABSTRACT Wild turkeys ( Meleagris gallopavo ) are hosts to several vector-borne haemosporidian blood parasites that can cause morbidity and mortality in wild and domestic turkeys. This study investigated the prevalence, geographical distribution, and genetic diversity of haemosporidians in 942 wild turkeys from the USA and 12 ocellated turkeys ( Meleagris ocellata ) from Belize. Haemoproteus was detected in 69% (650/942) of USA turkeys. Sequencing revealed six unique haplotypes in two lineages (1a-1c and 2a-2c). Haplotypes 1a-1c were 99.4–99.8% similar, and haplotype 1a was identical to a Haemoproteus reported in northern bobwhite ( Colinus virginianus ). Haplotypes 2a-2c were 98.2–99.2% similar, and haplotype 2a was most similar (99.1%) to Haemoproteus reported from galliforms in Austria and Thailand. Lineage 1 sequences were only 96.9–98.2% similar to Lineage 2. Lineage 1 (1a-1c) was detected in 84.6% (523/618) of Haemoproteus -positive USA turkeys, with haplotype 1a being most common (81.9%, 506/618). Lineage 2 (2a-2c) was detected in 43.4% (268/618) of USA turkeys. Leucocytozoon was detected in 9.7% (91/942) of USA wild turkeys, and all were identical to a Leucocytozoon from northern bobwhite. Haemoproteus prevalence was higher in males vs females and adults vs juveniles, and Leucocytozoon prevalence was higher in adults vs juveniles. No Plasmodium infections were detected. Haemoproteus was the only parasite detected in ocellated turkeys; 12 (100%) were infected with Lineage 1a, and four (33.3%) were co-infected with Lineage 2a. These findings provide new insights into the prevalence and genetic diversity of haemosporidians in turkeys.
