seroprevalence and risk factors associated to mycobacterium bovis in wild artiodactyl species from southern spain, 2006-2010.the control of bovine tuberculosis (btb) is at a critical point in the last stage of eradication in livestock. wildlife species recently have emerged infected with tb in europe, particularly ungulates in the iberian peninsula. epidemiological information regarding tb in wild ungulates including affected species, prevalence, associated risk factors and appropriate diagnostic methods need to be obtained in these countries. a cross-sectional study was carried out on wild artiodactyl species, includ ...201222523563
applicability of major histocompatibility complex drb1 alleles as markers to detect vertebrate hybridization: a case study from iberian ibex × domestic goat in southern spain.hybridization between closely related wild and domestic species is of great concern because it can alter the evolutionary integrity of the affected populations. the high allelic variability of major histocompatibility complex (mhc) loci usually excludes them from being used in studies to detect hybridization events. however, if a) the parental species don't share alleles, and b) one of the parental species possesses an exceptionally low number of alleles (to facilitate analysis), then even mhc l ...201223006678
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.g., red deer (cervus elaphus) and roe deer (capreolus capreolus)) may play in the parasit ...201627198769
shedding of clostridium difficile pcr ribotype 078 by zoo animals, and report of an unstable metronidazole-resistant isolate from a zebra foal (equus quagga burchellii).clostridium difficile is an emerging and potentially zoonotic pathogen, but its prevalence in most animal species, including exhibition animals, is currently unknown. in this study we assessed the prevalence of faecal shedding of c. difficile by zoo animals, and determined the ribotype, toxin profile and antimicrobial susceptibility of recovered isolates. a total of 200 samples from 40 animal species (36.5% of which came from plains zebra, equus quagga burchellii) were analysed. c. difficile was ...201424467928
