“…Body weight was shown to have an almost linear relationship with age up to around 0.8 kg or 4 months ( 41 ). As rabbits weighing >1 kg are considered adults, our results suggest that survival to adulthood is associated with high NARs for both viruses, emphasizing their role in the population dynamics of European rabbits ( 16 , 32 ). Nevertheless, many adult rabbits were seronegative for MYXV and RHDV GI.2, in contrast to what was described for Oryctolagus cuniculus cuniculus ( 31 ).…”

“…While the time span of serological data for individual rabbits in this study was relatively short (the maximum interval between the first and last capture of individual rabbits was 36 months), it should be noted that the life span of wild European rabbits is also short, mainly due to predation and diseases (for example, see reference 31 ; reviewed in reference 32 ). A life span of 7.6 years was recorded in Australia, where rabbit predators are less common than in the Iberian Peninsula ( 33 ).…”

“…The emergence of myxomatosis and RHD (i.e., GI.1) in the twentieth century, as well as the recent new RHD strain outbreak in 2010 (i.e., GI.2), have been the primary determinants for the decline of wild European rabbits within their native range (e.g., [3,12,45]). According to our findings, rabbit populations in Spain showed a positive trend in the years before the first outbreak of GI.1, when rabbit numbers dropped by around 53%.…”

The outbreaks of two strains of rabbit haemorrhagic disease (RHD) (GI.1 and GI.2) in the Iberian Peninsula have caused substantial economic losses in commercial rabbitries and have affected the conservation of rabbit-sensitive predators due to the dramatic decline of their natural populations. However, the assessment of the impact of both RHD strains on wild rabbit populations has been limited to a few small-scale studies. Little is known about the overall impact within its native range. In this study, we described and compared the effects of GI.1 and GI.2 countrywide by using time series of hunting bag data widely available across the country and compared their trend during the first eight years after the first outbreak of GI.1 (i.e., 1998) and GI.2 (i.e., 2011), respectively. We used Gaussian generalised additive models (GAM) with the number of hunted rabbits as the response variable and year as the predictor to evaluate the non-linear temporal dynamics of the population at the national and regional community levels. The first GI.1 caused a population decline of around 53%, affecting most Spanish regional communities where the disease occurred. The positive trend observed after GI.1 in Spain ended with the initial outbreak of GI.2, which did not appear to cause a national population decline. In contrast, we found significant variability in the rabbit population trend among regional communities, where some increased, and others decreased. Such a disparity is unlikely to be explained by a single factor; rather, it appears to result from several factors, such as climatic conditions, host resistance improvement, virulence attenuation, or population density. Our study suggests that a national comprehensive hunting bag series could aid in elucidating the differences in the impact of emerging diseases on a large scale. Future research should focus on national longitudinal serological studies to shed light on the immunological status of rabbit populations in different regions to better understand the evolution of RHD strains and the resistance gained by the wild populations.

Background Several species belonging to the genus Ehrlichia are considered pathogenic for animals and humans. Although wildlife are known to play an important role in the epidemiology of these bacteria, information on the role of wild lagomorphs in their sylvatic cycle is limited. Thus, the objective of the present study was to assess the occurrence of Ehrlichia spp. in ticks collected from wild lagomorphs in Spanish Mediterranean ecosystems. Methods A total of 1122 pooled ticks (254 pools) collected from 506 wild rabbits (Oryctolagus cuniculus) and 29 Iberian hares (Lepus granatensis) were analysed using a nested PCR assay targeting the partial groEL gene. Ehrlichia spp.-positive samples were further subjected to a second PCR assay targeting 16S rRNA. Results Three (1.2%) tick pools comprising Rhipicephalus pusillus collected from nine wild rabbits were positive for Ehrlichia spp. All the Ehrlichia DNA sequences were identical, and use of sequence and phylogenetic analyses allowed us to identify a novel Ehrlichia species. Conclusions We provide evidence that a novel Ehrlichia species, named herein as ‘Candidatus Ehrlichia andalusi’, which may be of concern for animal and public health, is circulating in R. pusillus in Spanish Mediterranean ecosystems. Further studies are warranted to assess the epidemiology, pathogenicity and zoonotic potential of this Ehrlichia species. Graphical Abstract
