Molecular survey of Besnoitia spp. (Apicomplexa) in faeces from European wild mesocarnivores in Spain.

Numerous studies have unsuccessfully tried to unravel the definitive host of the coccidian parasite Besnoitia besnoiti. Cattle infections by B. besnoiti cause a chronic and debilitating condition called bovine besnoitiosis that has emerged in Europe during the last two decades, mainly due to limitations in its control associated with the absence of vaccines and therapeutical tools.

Parasites of the Reintroduced Iberian Lynx () and Sympatric Mesocarnivores in Extremadura, Spain.

The Iberian lynx () is one of the most endangered felid species in the world. Conservation efforts have increased its population size and distribution and reinforced their genetic diversity through captive breeding and reintroduction programmes. Among several threats that the Iberian lynx faces, infectious and parasitic diseases have underlined effects on the health of their newly reintroduced populations, being essential to identify the primary sources of these agents and assess populations health status.

Detection of Myxoma Virus DNA in Ticks from Lagomorph Species in Spain Suggests Their Possible Role as Competent Vector in Viral Transmission.

Myxoma virus (MYXV) causes morbidity and mortality in European wild rabbits (Oryctolagus cuniculus) worldwide, and recently in Iberian hares (Lepus granatensis) in Spain. We aimed to assess the presence of MYXV-specific DNA in ixodid ticks collected from both hosts. A total of 417 ticks harvested from 30 wild lagomorphs, including wild rabbits and Iberian hares were collected from southern Spain.

Microbial community of Hyalomma lusitanicum is dominated by Francisella-like endosymbiont.

(Apicomplexa) in Fallow Deer () from Spain: Ultrastructure and New Host Record.

Members of the genus are frequently found infecting members of the family Cervidae. Although species are generally host specific for their intermediate hosts, species in cervids appear to be less host specific. Here, we report fallow deer () as a new host for , originally described from the red deer ().

Survey of Crimean-Congo Hemorrhagic Fever Enzootic Focus, Spain, 2011-2015.

During 2011-2015, we conducted a Crimean-Congo hemorrhagic fever virus (CCHFV) survey in captured ticks that were feeding mainly on wild and domestic ungulates in Spain, where presence of this virus had been reported previously. We detected CCHFV RNA in Hyalomma lusitanicum and H. marginatum ticks for 3 of the 5 years.

Occurrence and molecular genotyping of Giardia duodenalis and Cryptosporidium spp. in wild mesocarnivores in Spain.

There is a surprisingly scarce amount of epidemiological and molecular data on the prevalence, frequency, and diversity of the intestinal protozoan parasites Giardia duodenalis and Cryptosporidium spp. in wildlife in general and mesocarnivore species in particular. Consequently, the extent of the cyst/oocyst environmental contamination attributable to these wild host species and their potential implications for public veterinary health remain largely unknown.

Sarcoptes scabiei infestation does not alter the stability of ectoparasite communities.

Background: The host represents a heterogeneous ecosystem where multiple parasite species co-occur and interact with each other for space and resources. Although these interactions may rule the features of an infracommunity and may shape the infracommunity response to external perturbations, the resilience of ectoparasite communities to new infestations remains poorly explored.

Methods: We analysed the composition of the ectoparasite communities found on 214 individual Iberian ibexes (Capra pyrenaica) inhabiting the Sierra Nevada Natural Space, southern Spain.

The role of wild ruminants as reservoirs of Besnoitia besnoiti infection in cattle.

Bovine besnoitiosis, a parasitic disease caused by Besnoitia besnoiti, has been reported mainly in beef cattle raised under extensive pastoral systems and is considered to be re-emerging in Western Europe. Horizontal transmission probably occurs either by means of blood sucking arthropods or as a consequence of direct contact between infected and non-infected cattle. However, the role that wild ruminants (e.

Molecular characterization of bot flies, Oestrus spp., (Diptera, Oestridae), from domestic and wild Bovidae hosts.

The identification of Oestrus spp. larvae from Bovidae hosts is a difficult task due to the great morphological similarity between species. The lack of unambiguous identification criteria could have also serious epidemiological implications since domestic and wild hosts are sympatric in many natural areas.
