Avian Hemosporidian Parasite Lineages in Four Species of Free-ranging Migratory Waterbirds from Mongolia, 2008.

Avian hemosporidian parasites have been detected in Asia, but little information is known about the hemosporidian parasite lineages that circulate in waterbirds that migrate along the East Asian and Central Asian migratory flyways to breed in Mongolia. To gather baseline data on hemosporidian parasite presence in Mongolian waterbirds, 151 blood-spot samples (81 hatch year [HY] and 70 after hatch year [AHY]) from Bar-headed Goose (Anser indicus), Ruddy Shelduck (Tadorna ferruginea), Great Cormorant ( Phalacrocorax carbo ), and Mongolian Gull (Larus mongolicus) were screened for three genera of apicomplexan parasites, Plasmodium, Haemoproteus, and Leucocytozoon, using nested PCR. Of these, 17 samples (11%, 95% confidence interval: 7.
