| prevalence of encysted toxoplasma gondii in raptors from alabama. | little is known about the prevalence of encysted toxoplasma gondii in wild birds. we examined the hearts and breast muscles from 101 raptors for encysted t. gondii. all of the raptors had been submitted for necropsy to the state veterinary diagnostic laboratory, auburn, alabama. tissues were digested in acid-pepsin solution and inoculated into groups of 3-5 laboratory mice. toxoplasma gondii was isolated from 27 of 101 (26.7%) raptors: 8 of 12 (66.7%) red-shouldered hawks (buteo lineatus), 13 of ... | 1993 | 8277379 |
| prevalence of encysted apicomplexans in muscles of raptors. | 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 ... | 1999 | 9950339 |
| antibody prevalence and isolation of viable toxoplasma gondii from raptors in the southeastern usa. | raptors are good indicators of the prevalence of toxoplasma gondii in the environment because they prey on small mammals and birds. these prey species are a major source of infection in domestic cats ( felis catus ), which shed the environmentally resistant oocysts. we assessed t. gondii infection in 281 opportunistically available raptors at a rehabilitation facility between 2012 and 2014. antibodies to t. gondii were assayed by a modified agglutination test (cutoff 1:25) and found in serum of ... | 2016 | 27243150 |
| new data on neodiplostomum americanum chandler and rausch, 1947 (digenea: diplostomidae), in the great horned owl bubo virginianus gmelin, 1788 and the eastern screech owl megascops asio linnaeus, 1758 in mississippi, usa. | neodiplostomum americanum chandler and rausch, 1947 has been reported from six species of owls in north america. at present, there are no molecular data for this species and gene sequence data from neodiplostomum railliet, 1919 are limited. a freshly deceased specimen of the great horned owl bubo virginianus gmelin, 1788 and a freshly deceased specimen of the eastern screech owl megascops asio linnaeus, 1758 were collected in oktibbeha county, mississippi in 2014 and 2016, respectively. neodiplo ... | 2017 | 28634620 |
