hemosporidian blood parasites in seabirds--a comparative genetic study of species from antarctic to tropical habitats.whereas some bird species are heavily affected by blood parasites in the wild, others reportedly are not. seabirds, in particular, are often free from blood parasites, even in the presence of potential vectors. by means of polymerase chain reaction, we amplified a dna fragment from the cytochrome b gene to detect parasites of the genera plasmodium, leucocytozoon, and haemoproteus in 14 seabird species, ranging from antarctica to the tropical indian ocean. we did not detect parasites in 11 of the ...201020652673
