This update on the African swine fever (ASF) outbreaks in EU demonstrated that out of all tested wild boar found dead, proportion positive samples peaked winter and summer. For domestic pigs only, a summer peak was evident. Despite existence several plausible factors could result observed seasonality, there is no evidence to prove causality. Wild density most influential risk factor for occurrence ASF boar. In vast majority introductions pig holdings, direct contact with infected or excluded...

Wild boars are important disease reservoirs. It is well known that abundance estimates needed in wildlife epidemiology, but the expense and effort required to obtain them prohibitive. We evaluated a simple method based on frequency of faecal droppings found transects (FBII), developed spatial aggregation index, runs test statistic. Estimates were compared with hunting data, porcine circovirus Aujeszky's virus seroprevalences Mycobacterium tuberculosis complex Metastrongylus spp. prevalence....

ABSTRACT Tuberculosis (TB) is a chronic disease caused by Mycobacterium bovis and related members of the tuberculosis complex. Infection affects not only cattle but also other livestock species, companion animals wild mammals. Humans are susceptible; hence, zoonotic infection driver for control in animal hosts. As bovine TB prevalence has been reduced livestock, relative epidemiological socio‐economic importance wildlife reservoirs increased, there need management strategies. We review...

Abstract When human interventions interfere with the natural regulation of wildlife populations by favouring some species, overabundance can emerge. We evaluated different methods estimating red deer abundance in a wide range population densities from southern Spain. Distance sampling estimates were used as reference method across 22 localities and compared two kilometric indices (KAIs), four based on pellet group counts browsing (BWIs). The average density estimated distance was 19.51±3.19...

Doñana National Park (DNP) in southern Spain is a UNESCO Biosphere Reserve where commercial hunting and wildlife artificial feeding do not take place traditional cattle husbandry still exists. Herein, we hypothesized that Mycobacterium bovis infection prevalence wild ungulates will depend on host ecology variation reflect the interaction between hosts environmental risk factors. Cattle bTB reactor rates increased DNP despite compulsory testing culling of infected animals. In this study, 124...

Abstract Background The role of wildlife as a brucellosis reservoir for humans and domestic livestock remains to be properly established. aim this work was determine the aetiology, apparent prevalence, spatial distribution risk factors transmission in several Iberian wild ungulates. Methods A multi-species indirect immunosorbent assay (iELISA) using Brucella S-LPS antigen developed. In regions having livestock, individual serum samples were taken between 1999 2009 from 2,579 bovids, 6,448...

Controlling infectious diseases at the wildlife/livestock interface is often difficult because ecological processes driving transmission between wildlife reservoirs and sympatric livestock populations are poorly understood. Thus, assessing how animals use their environment this affects interspecific interactions an important factor in determining local risk for disease maintenance. We used data from concurrently monitored GPS-collared domestic cattle wild boar (Sus scrofa) to assess...

The European Commission requested EFSA to compare the reliability of wild boar density estimates across EU and provide guidance improve data collection methods. Currently, only EU-wide available are hunting data. Their methods should be harmonised comparable predictive models for density. These could validated by more precise data, collected at local level e.g. camera trapping. Based on practical theoretical considerations, it is currently not possible establish thresholds that do allow...

Tuberculosis (TB) caused by Mycobacterium bovis and closely related members of the tuberculosis complex continues to affect humans animals worldwide its control requires vaccination wildlife reservoir species such as Eurasian wild boar (Sus scrofa). Vaccination efforts for TB in have been based primarily on oral live BCG formulations. However, this is first report use inactivated vaccines controlling wildlife. In study, four groups 5 each were vaccinated with M. intramuscular routes, or left...
