Ticks are vectors of zoonotic diseases of relevant concern for Public Health. Birds are host of these arthropods and they can transport them during their movements, migratory or not.
Data about microorganisms harboured by ticks from birds in Spain are scarce. This fact highlighted the necessity of investigating the role of these vertebrates in the epidemiology of arthropod-borne diseases. Thereby, several studies, that have been published in seven scientific articles and one communication in an international congress, were carried out and they are showed in this manuscript.
Tick specimens collected from birds in the Iberian Peninsula, and occasionally in Morocco, were studied to assess the presence of bacteria (Anaplasma/Ehrlichia, Borrelia, Rickettsia and Spiroplasma) and viruses (Crimean-Congo hemorrhagic fever virus, Flavivirus, Phlebovirus, Coltivirus and Orbivirus) using molecular biology techniques.
In these studies, ticks belonging to five species (Haemaphysalis punctata, Hyalomma marginatum, Ixodes arboricola, Ixodes frontalis and Ixodes ricinus) and captured over birds, mainly passerine and many of them migratory species, were analized. Anaplasma phagocytophilum, Anaplasma centrale, Borrelia garinii, Borrelia turdi, Borrelia valaisiana, Rickettsia aeschlimannii, Rickettsia hevetica, Rickettsia monacensis, Rickettsia sibirica subsp. mongolitimonae and Rickettsia sibirica subsp. sibirica were detected. These works have allowed to describe microorganisms for the first time in Southwest Europe, in ticks from birds or/and in tick species not previously associated with these bacteria. Moreover, a new Rickettsia species, Candidatus Rickettsia vini, has been identified with a high prevalence in I. arboricola.
Lastly, Crimean-Congo hemorrhagic fever virus has been amplified in Hy. marginatum specimens captured in Morocco from birds in migration. This finding supported the hypothesis of the virus arrival to the Iberian Peninsula from Africa through the infected ticks from birds. In addition, it demonstrated the presence of the Crimean-Congo hemorrhagic fever virus in Northwest Africa.
These studies demonstrate the important role of birds as tick dispersals and the infectious agents that they carry. |

Entre los hospedadores de estos ácaros se encuentran las aves, que son capaces de transportarlas durante sus desplazamientos migratorios o no. La escasez de datos sobre los microorganismos vehiculados por garrapatas de aves en España puso de manifiesto la necesidad de investigar el papel de estos vertebrados en la epidemiología de las enfermedades transmitidas por artrópodos. Así, se llevaron a cabo diversos estudios que han sido publicados en siete artículos científicos y una comunicación en un congreso internacional. Se estudiaron ejemplares de garrapatas recogidos de aves en la Península Ibérica, y puntualmente en Marruecos, con objeto de investigar la presencia de bacterias (Anaplasma/Ehrlichia, Borrelia, Ricketlsia y Spiroplasma) y virus (virus de la fiebre hemorrágica de Crimea-Congo, Flavivirus. Phlebovirus. Coltivirus y Orbivirus) mediante térmicas de biología molecular. En el conjunto de los estudios se analizaron ejemplares de cinco especies de garrapatas (Haemaphysals punctata. Hyalomma marginaium, lxodes arboricola, lxodes frontalis e lxodes ricinus) recogidos principalmente de aves paseriformes, muchas de ellas migratorias. En ellas, se detectó Anaplasma phagocytophilum, Anaplasma centrale, Borrelia garinili, Borrelia turdi, Borrelia valaisiana. Ríckettsia aeschlimannii, Rickettsia hevetica, Rickettsia monacensis, Rickettsia sibirica subsp, mongolitlmonae y Rickettsia sibirica subsp, sibirica. Estos trabajos han permitido describir microorganismos por primera vez en Europa occidental, en garrapatas de aves y/o en especies de garrapatas con los que no se hablan asociado previamente. Además, se ha identificado una nueva especie de Rickettsia. Candidatus Rickettsía vini, con alta prevalencia en l. arboricola. Por último, se amplífico el virus de la liebre hemorrágica de Crimea-Congo en ejemplares de Hy. marginatum recogidos en Marruecos sobre aves en migración, hecho que refuerza la hipótesis de la llegada del virus a la Península Ibérica por esta vía desde África. Además, este hallazgo demuestra la presencia del virus de la fiebre hemorrágica de Crimea-Congo en el noroeste de África. Estos estudios demuestran el imponente papel de las aves como dispersoras de garrapatas y de los agentes infecciosos que vehiculan.Universidad de La Rioja (España)Oteo Revuelta, José Antonio (null)Portillo Barrio, Aránzazu (null)2017text (thesis)application/pdfhttps://dialnet.unirioja.es/servlet/oaites?codigo=122702spaLICENCIA DE USO: Los documentos a texto completo incluidos en Dialnet son de acceso libre y propiedad de sus autores y/o editores.
