Presence of Borrelia turdi and Borrelia valaisiana (Spirochaetales: Spirochaetaceae) in Ticks Removed From Birds in the North of Spain, 2009-2011.

The genus Borrelia includes species responsible for severe human diseases such as Lyme disease. Birds are involved in their epidemiology as dispersers of infected ticks (Ixodida: Ixodidae) and as reservoirs or amplifiers of the bacterium. Herein, the presence of Borrelia burgdorferi sensu lato (s.

Molecular analysis of Crimean-Congo hemorrhagic fever virus and Rickettsia in Hyalomma marginatum ticks removed from patients (Spain) and birds (Spain and Morocco), 2009-2015.

Crimean-Congo hemorrhagic fever virus (CCHFV) was detected in Spain in 2010. The presence of CCHFV in Hyalomma marginatum ticks from migratory birds passing through Morocco during the spring migration strengthened the hypothesis of the arrival of infected ticks transported by birds to the Iberian Peninsula. Furthermore, Hyalomma species are vectors of bacterial infections such as spotted fever rickettsioses.

Prevalence of 'Candidatus Rickettsia vini' in Ixodes arboricola ticks in the North of Spain, 2011-2013.

Background: The prevalence of Rickettsia spp. in Ixodes arboricola ticks collected from birds in two locations in the North of Spain from 2011 to 2013 was studied.

Findings: The detection of the bacteria in 54 DNA extracts of I.

Crimean-Congo hemorrhagic fever virus in ticks from migratory birds, Morocco.

Crimean-Congo hemorrhagic fever virus was detected in ticks removed from migratory birds in Morocco. This finding demonstrates the circulation of this virus in northwestern Africa and supports the hypothesis that the virus can be introduced into Europe by infected ticks transported from Africa by migratory birds.

Role of birds in dispersal of etiologic agents of tick-borne zoonoses, Spain, 2009.

We amplified gene sequences from Anaplasma phagocytophilum, Borrelia garinii, B. valaisiana, B. turdi, Rickettsia monacensis, R.
