| molecular detection of bacteria in the families rickettsiaceae and anaplasmataceae in northern crested caracaras (caracara cheriway). | bacterial pathogens of the families anaplasmataceae and rickettsiaceae are often spread to humans or other animals from bites from infected arthropod hosts. recently, an increasing number of studies have implicated migratory birds in the circulation of these pathogens through the spread of arthropod vectors. however, few studies have examined the potential for resident bird populations to serve as reservoirs for these zoonoses. in this study, we used nested pcrs of the groesl and 17 kda genes to ... | 2016 | 26837860 |
| External parasites of raptors (Falconiformes and Strigiformes): identification in an ex situ population from Mexico. | Raptorial birds harbor a variety of ectoparasites and the mayority of them are host specific. The aim of this study was to identify the ectoparasites of captive birds of prey from Mexico, as well as to verify their impact in the health of infested birds. Raptorial birds were confiscated and kept in captivity at the Centro de Investigación y Conservación de Vida Silvestre (CIVS) in Los Reyes La Paz, Mexico State. Seventy-four birds of prey (66 Falconiformes and eigth Strigiformes) of 15 species w ... | 2011 | 22017130 |
| prevalence of antibodies to west nile virus and other arboviruses among crested caracaras (caracara cheriway) in florida. | we documented the antibody prevalence to three arboviruses, st. louis encephalitis virus (slev), eastern equine encephalitis virus (eeev), and west nile virus (wnv), in crested caracaras (caracara cheriway; n = 80) in florida from 2007 to 2008. antibody prevalence to wnv was higher (9%) than for the other viruses. most seropositive birds were adults (< or =3 yr of age), with 55% of adults testing positive for antibodies to at least one virus. adults were significantly more likely to have antibod ... | 2009 | 19617494 |
| granulomatous filarial encephalomyelitis caused by chandlerella quiscali in a northern crested caracara (caracara cheriway). | a northern crested caracara (caracara cheriway) was presented after being found nonambulatory in a field. on physical examination, the bird had severe hind-limb paresis. the bird did not improve after 10 days of hospitalization and was euthanized. histologic examination of the cerebrum and spinal cord revealed multiple adult filarial nematodes surrounded by granulomatous inflammation with several multinucleated giant cells. these parasites were confirmed to be chandlerella quiscali with polymera ... | 2017 | 28363039 |
| validity of bartram's painted vulture (aves: cathartidae). | william bartram described the painted vulture (vultur sacra) as a new species in his 1791 book on travels in florida and other southeastern states. however, no specimen of this bird survives, and it has not been reported by any subsequent ornithologist. bartram's detailed description is not presently endorsed by the american ornithologists' union and has been widely regarded as a myth, a misdescribed king vulture sarcoramphus papa (linnaeus), a misdescribed northern caracara caracara cheriway (j ... | 2013 | 24698902 |
| new insights into the clinico-histopathological and molecular features of pelecitus (filarioidea: onchocercidae) from a raptor bird. | some onchocercidae nematodes such as pelecitus are parasites of medical and veterinary importance. the adult stage of pelecitus has been reported infecting birds, and the microfilaria has been associated to human blindness. however, in some of these cases, the nematode was incompletely identified at the species level due to the scarcity of morphological taxonomic keys and, also, to the lack of molecular diagnostic analysis. here, we report a new pelecitus species in a crested caracara (caracara ... | 2018 | 30006807 |
