“…Several gastrointestinal parasites frequently reported in raptors worldwide (Hoberg et al 1989, Ferrer et al 2004a, Ferrer et al 2004b were not identified in this study. Failure to identify some parasites may be due to differences in the geographic distribution of the hosts and/or parasites, the feeding habits of host species, and the material origin (Baker et al 1996).…”

“…Infectious diseases caused by bacterial, viral, fungal, and/or parasitic origin are common in wild and captive birds of prey (Deem 1999, Jones 2006. Though parasites are the most frequent pathogens in raptors, the gastrointestinal and respiratory tracts are most commonly affected by nematodes, trematodes, cestodes, acanthocephalans and protozoans (Baker et al 1996, Aguilar 2001, Ferrer et al 2004a, Ferrer et al 2004b, Leppert et al 2008, Silva et al 2009). Overt clinical signs of parasitism are not common, subclinical parasitism may become evident during stress conditions, and heavy infections by gastrointestinal parasites may cause diarrhea, anorexia, emaciation, listlessness, and death (Baker et al 1996, Morishita 1997, Freitas et al 2002, Jones 2006.…”

Successful programs for ex situ and in situ conservation and management of raptors require detailed knowledge about their pathogens. The purpose of this study was to identify the internal parasites of some captive raptors in Mexico, as well as to verify their impact in the health status of infected birds. Birds of prey were confiscated and kept in captivity at the Centro de Investigación y Conservación de Vida Silvestre (CIVS) in Los Reyes La Paz, Mexico State. For this, fecal and blood samples from 74 birds of prey (66 Falconiformes and eight Strigiformes) of 15 species, juveniles and adults from both sexes (39 males and 35 female), were examined for the presence of gastrointestinal and blood parasites. Besides, the oropharyngeal cavity was macroscopically examined for the presence of lesions compatible with trichomoniasis. Among our results we found that lesions compatible with Trichomonas gallinae infection were detected only in two Red-tailed hawks (Buteo jamaicensis) (2.7%); nevertheless, infected birds were in good physical condition. Overall, gastrointestinal parasites were found in 10 (13.5%) raptors: nine falconiforms (13.6%) and one strigiform (12.5%), which mainly presented a single type of gastrointestinal parasite (90%). Eimeria spp. was detected in Harris's hawk (Parabuteo unicinctus), Swainson's hawk (Buteo swainsoni), Red-tailed hawk (B. jamaicensis) and Great horned owl (Bubo virginianus); whereas trematodes eggs were found in Peregrine falcon (Falco peregrinus) and Swainson's hawk (B. swainsoni). Furthermore, eggs of Capillaria spp. were found in one Swainson's hawk (B. swainsoni), which was also infected by trematodes. Hemoprotozoarian were detected in five (6.7%) falconiforms: Haemoproteus spp. in American kestrel (F. sparverius) and Leucocytozoon spp. in Red-tailed hawk (B. jamaicencis). Despite this, no clinical signs referable to gastrointestinal or blood parasite infection were observed in any birds. All parasites identified were recorded for the first time in raptors from Mexico. Furthermore, this represents the first report for T. gallinae, trematodes, Haemoproteus spp. and Leucocytozoon spp. in raptors from Latin America. Diagnosis and control of parasitic infections should be a part of the routine in health care evaluations for ex situ raptor populations. Finally, this information is also valuable for in situ conservation actions on these birds. Rev. Biol. Trop. 59 (3): 1265-1274. Epub 2011 September 01.

“…The Tetrameres genus is quite common in waterfowls (Sitko & Okulewicz, 2010) but very rare in birds of prey. Ferrer et al (2004) confi rmed Tetrameres sp. in S. aluco in Spain, but the specimen was not determined up to the species level.…”

“…Complex surveys involving all three major orders of birds of prey (omitting passeriform shrikes of the Laniidae family) were conducted in the Netherlands (Borgsteede et al, 2003), Spain (Sanmartín et al, 2004;Illescas Gomez et al, 1993), and Italy (Santoro et al, 2012a, b). Ferrer et al (2004) examined the incidence of helminths only in owls from the territory of Spain. In the Czech Republic, Sitko published decades-long scientifi c studies of fl ukes in diurnal (1998) and nocturnal raptors (2001).…”

“…The majority of literature data on acanthocephalans of birds of prey suggests a rather low host specifi city of individual species of the Centrorhynchus genus. For instance, C. aluconis is considered as an owl parasite in Europe (Kutzer et al, 1982;Kritscher 1985;Ewald & Crompton, 1993;McInnes et al, 1994;Sitko 1994;Dimitrova et al, 1995;Ferrer et al 2004;Dimitrova & Dimitrova 2012;Santoro et al, 2012b;Lisitsyna & Greben, 2015), but it has sometimes been observed also in diurnal raptors (Yamaguti 1963, Illescas Gomez et al 1993Borgsteede et al 2003, Sitko 2011. On the other hand, C. buteonis has been documented not only in Falconiformes and Accipitriformes, but also in owls, especially in the Strix genus (Furmaga, 1957;Yamaguti, 1963;Michálek, 1984;Kritscher, 1985;Sitko 2011;Dimitrova & Dimitrova, 2012;Shirazi et al, 2014).…”

New data on helminth fauna of birds of prey (Falconiformes, Accipitriformes, Strigiformes) in the Slovak Republic

SummaryIn the years 2012-2014, carcasses of 286 birds of prey from the territory of Slovakia were examined for the presence of helminth parasites. The number of bird species in the study was 23; fi ve belonging to the Falconiformes order, eleven to Accipitriformes, and seven to Strigiformes. A fi nding of Cestoda class comprehended 4 families: Paruterinidae (4), Dilepididae (2), Mesocestoididae (2) and Anoplocephalidae (1). Birds of prey were infected with 6 families Nematoda species of the Secernentea class: Syngamidae (1), Habronematidae (2), Tetrameridae (3), Physalopteridae (1), Acuariidae (1), and Anisakidae (2). Out of the Adenophorea class, the Capillariidae family (1) was confi rmed. The Acanthocephala group was represented by the Paleacanthocephala class, the Centrorhynchidae family (3). Out of the Trematoda class, 12 different species of fl ukes were found, belonging to the Diplostomidae (5), Cyathocotylidae (1), Strigeidae (4), Opistorchidae (1), and Plagiorchidae (1) families. The most frequent helminth species infecting diurnal birds of prey was Strigea falconis. This fl uke was confi rmed in one bird species from the Falconiformes order and in eight species from the Accipitriformes order. In nocturnal birds of prey, the most common fi nding was the acanthocephalan Centrorhynchus aluconis, identifi ed in four different host species of the Strigiformes order. In total, 23 helminth species were recorded for the fi rst time in Slovakia.

The avian acanthocephalan Plagiorhynchus cylindraceus (Palaeacanthocephala) parasitizing the European hedgehog (Erinaceus europaeus) in Europe and New Zealand

The palaeacanthocephalan Plagiorhynchus cylindraceus is a common intestinal parasite of passerine birds, which can also occur parenterally or in the intestinal tract of mammals, often as an invading species in many countries worldwide. In this survey, introduced hedgehogs (Erinaceus europaeus, n = 183) killed in New Zealand during a biocontrol campaign and conspecifics (n = 174) that had died in hedgehog rehabilitation centers in Germany and Britain were examined for this parasite. In New Zealand, P. cylindraceus is recorded for the first time here, in the vicinity of Auckland. In Europe, prevalences ranged from 4.2% up to 47.6%, while in New Zealand, only 1.6% (Auckland 7.9%). Most of the worms occurred inside the peritoneal cavity where they had partly degenerated. Since hedgehogs are seldom preyed upon in continental Europe but often become traffic victims, we hypothesize that the worms inside them, whether extra- or intraperitoneally, contribute to the abundance and persistence of the parasite by being ingested by scavenging birds. Accordingly, we consider P. cylindraceus as a "modern parasite" taking advantage of two aspects of global change: anthropogenic promoted transmission (road kills) and the transcontinental spread of infected intermediate and/or final hosts caused by humans.
