An acid-pepsin digestion technique was used to examine portions of breast muscle and heart from raptors for encysted protozoans. Apicomplexan zoites were present in 52 (45.6%) of the 114 samples examined: 11 of 12 (91.7%) red-shouldered hawks (Buteo lineatus), 20 of 34 (58.8%) red-tailed hawks (Buteo jamaicensis), two of seven (28.6%) Cooper's hawks (Accipiter cooperi), three of four (75%) sharp-shinned hawks (Accipiter striatus), one (100%) Mississippi kites (Ictinia misisippiensis), one of two (50%) American kestrels (Falco sparverius), one bald eagle (Haliaeetus leucocephalus), one of two (50%) golden eagles (Aquila chrysaetos), one of three (33%) turkey vultures (Cathartes aura), two of three (66.7%) black vultures (Coragyps atratus), three of six (50%) great-horned owls (Bubo virginianus), five of 15 (33.3%) barred owls (Strix varia), and one of 12 (8.3%) screech owls (Asio otus). Encysted protozoans were not observed in digests of tissues from three broad-winged hawks (Buteo platypterus), four ospreys (Pandion haliaetus), and five barn owls (Tyto alba). Apicomplexan cysts resembling Sarcocystis species were observed in tissue sections of muscles from 28 (37.8%) of 74 raptors.
采用酸-胃蛋白酶消化技术检查猛禽的胸肌和心脏部分，以查找包囊内的原生动物。在所检查的114个样本中，有52个（45.6%）存在顶复门动合子：12只红肩鹰（赤肩鵟）中有11只（91.7%），34只红尾鹰（红尾鵟）中有20只（58.8%），7只库珀鹰（库氏鹰）中有2只（28.6%），4只条纹鹰（白腹鹰）中有3只（75%），1只密西西比鸢中有1只（100%），2只美洲隼中有1只（50%），1只白头海雕，2只金雕中有1只（50%），3只火鸡秃鹫中有1只（33%），3只黑秃鹫中有2只（66.7%），6只大角鸮中有3只（50%），15只横斑林鸮中有5只（33.3%），12只鸣角鸮中有1只（8.3%）。在3只阔翅鹰（阔翅鵟）、4只鹗和5只仓鸮的组织消化物中未观察到包囊内的原生动物。在74只猛禽中，有28只（37.8%）的肌肉组织切片中观察到类似肉孢子虫属的顶复门囊肿。
