isolation and epidemiology of falcon adenovirus.	an adenovirus was detected by electron microscopy in tissues from falcons that died during an outbreak of inclusion body hepatitis and enteritis that affected neonatal northern aplomado (falco femoralis septentrionalis) and peregrine (falco peregrinus anatum) falcons. molecular characterization has identified the falcon virus as a new member of the aviadenovirus group (m. schrenzel, j. l. oaks, d. rotstein, g. maalouf, e. snook, c. sandfort, and b. rideout, j. clin. microbiol. 43:3402-3413, 2005 ...	2005	16000467
characterization of a new species of adenovirus in falcons.	in 1996, a disease outbreak occurred at a captive breeding facility in idaho, causing anorexia, dehydration, and diarrhea or sudden death in 72 of 110 northern aplomado falcons (falco femoralis septentrionalis) from 9 to 35 days of age and in 6 of 102 peregrine falcons (falco peregrinus) from 14 to 25 days of age. sixty-two northern aplomado and six peregrine falcons died. epidemiologic analyses indicated a point source epizootic, horizontal transmission, and increased relative risk associated w ...	2005	16000466
falcon adenovirus in an american kestrel (falco sparverius).	a fatal adenovirus infection is described in a wild-caught american kestrel (falco sparverius). predominate lesions were a moderate to severe hepatitis with diffuse single-cell necrosis of hepatocytes and a splenitis characterized by necrosis of cells surrounding the sheathed arteries. pan-nuclear eosinophilic to magenta inclusion bodies were abundant within hepatocytes. polymerase chain reaction was used to amplify a portion of the hexon gene from dna extracted from the bird's liver and spleen. ...	2007	18065135
first detection of bacillus anthracis in feces of free-ranging raptors from central argentina.	prevalence of anthrax spores in feces of raptors was determined from samples collected in november-december 2000 and april-may 2001 in an agricultural region of santa fé province, argentina. feces were tested from 48 birds of six raptor species. one of 14 chimango caracaras (milvago chimango) and one of eight road-side hawks (buteo magnirostris) tested positive. the prevalence of bacillus anthracis spores in feces for the six species was 4% (n=48). the prevalence was 7% (n=14) for chimango carac ...	2007	17347404
persistent environmental pollutants in eggs of aplomado falcons from northern chihuahua, mexico, and south texas, usa.	the northern aplomado falcon (falco femoralis septentrionalis) disappeared from south texas in the 1940s. due to great success in the release of captive-reared aplomado falcons in south texas, there are currently more than 40 established nesting pairs in the region. addled eggs from aplomado falcons nesting in northern chihuahua and south texas were analyzed to determine organochlorine (oc) and inorganic element contaminant burdens and their potential association with egg failures and effects on ...	2008	17669494
pbdes, pcbs, and dde in eggs and their impacts on aplomado falcons (falco femoralis) from chihuahua and veracruz, mexico.	eggs from aplomado falcons (falco femoralis septentrionalis) nesting in chihuahua and veracruz, mexico, were analyzed for organochlorine pesticides, pcbs, and pbdes. p,p'-dde was the only organochlorine found in all eggs at concentrations ranging from 0.13 to 7.85 μg/g wet weight. pcbs ranged from 0.04 to 2.80 μg/g wet weight and pbdes from 62 to 798 ng/g lipid weight. dde concentrations in eggs were not significantly different among regions; however, pcbs were significantly greater (p = 0.015) ...	2011	21903314
persistent organic pollutants in eggs from south texas aplomado falcons.	a program to reintroduce the northern aplomado falcon (falco femoralis septentrionalis) in south texas and the southwestern united states was initiated in the late 1970s. fledgling aplomado falcons were first released in the laguna atascosa national wildlife refuge in 1993 and the first nesting pair in the area was recorded by 1995. during 2004-2017 we collected addled eggs from nesting pairs in the laguna atascosa national wildlife refuge and matagorda island in south texas, to determine if env ...	2020	33011574
