[Ab] Resumo:Functional roles of domestic and wild host populations in infectious keratoconjunctivitis (IKC) epidemiology have been extensively discussed claiming a domestic reservoir for the more susceptible wild hosts, however, based on limited data. With the aim to better assess IKC epidemiology in complex host-pathogen alpine systems, the long-term infectious dynamics and molecular epidemiology of Mycoplasma conjunctivae was investigated in all host populations from six study areas in the Pyrenees and one in the Cantabrian Mountains (Northern Spain). Detection of M. conjunctivae was performed by qPCR on 3600 eye swabs collected during seven years from hunted wild ungulates and sympatric domestic sheep (n = 1800 animals), and cluster analyses of the strains were performed including previous reported local strains. Mycoplasma conjunctivae was consistently detected in three Pyrenean chamois (Rupicapra p. pyrenaica) populations, as well as in sheep flocks (17.0% of sheep) and occasionally in mouflon (Ovis aries musimon) from the Pyrenees (22.2% in one year/area); statistically associated with ocular clinical signs only in chamois. Chamois populations showed different infection dynamics with low but steady prevalence (4.9%) and significant yearly fluctuations (0.0%- 40.0%). Persistence of specific M. conjunctivae strain clusters in wild host populations is demonstrated for six and nine years. Cross-species transmission between chamois and sheep and chamois and mouflon were also sporadically evidenced. Overall, independent M. conjunctivae sylvatic and domestic cycles occurred at the wildlife-livestock interface in the alpine ecosystems from the Pyrenees with sheep and chamois as the key host species for each cycle, and mouflon as a spill-over host. Host population characteristics and M. conjunctivae strains resulted in different epidemiological scenarios in chamois, ranging from the fading out of the mycoplasma to the epidemic and endemic long-term persistence. These findings highlight the capacity of M. conjunctivae to establish diverse interactions and persist in host populations, also with different transmission conditions.

[Ti] Título:Ancient mitochondrial pseudogenes reveal hybridization between distant lineages in the evolution of the Rupicapra genus.

[Ab] Resumo:Mitochondrial pseudogenes (numts) inserted in the nuclear genome are frequently found in population studies. Its presence is commonly connected with problems and errors when they are confounded with true mitochondrial sequences. In the opposite side, numts can provide valuable phylogenetic information when they are copies of ancient mitochondrial lineages. We show that Rupicapra individuals of different geographic origin from the Cantabrian Mountains to the Apennines and the Caucasus share a nuclear COI fragment. The numt copies are monophyletic, and their pattern of differentiation shows two outstanding features: a long evolution as differentiated true mitochondrial lineage, and a recent integration and spread through the chamois populations. The COI pseudogene is much older than the present day mitochondrial clades of Rupicapra and occupies a basal position within the Rupicapra-Ammotragus-Arabitragus node. Joint analysis of this numt and a cytb pseudogene with a similar pattern of evolution places the source mitochondrial lineage as a sister branch that separated from the Ammotragus-Arabitragus lineage 6millionyearsago (Mya). The occurrence of this sequence in the nucleus of chamois suggests hybridization between highly divergent lineages. The integration event seems to be very recent, more recent than the split of the present day mtDNA lineages of Rupicapra (1.9Mya). This observation invites to think of the spread across the genus by horizontal transfer through recent male-biased dispersal.

[Ab] Resumo:The inferred phylogenetic relationships between organisms often depend on the molecular marker studied due to the diverse evolutionary mode and unlike evolutionary histories of different parts of the genome. Previous studies have shown conflicting patterns of differentiation of mtDNA and several nuclear markers in chamois (genus Rupicapra) that indicate a complex evolutionary picture. Chamois are mountain caprine that inhabit most of the medium to high altitude mountain ranges of southern Eurasia. The most accepted taxonomical classification considers two species, R. pyrenaica (with the subspecies parva, pyrenaica and ornata) from southwestern Europe and R. rupicapra (with the subspecies cartusiana, rupicapra, tatrica, carpatica, balcanica, asiatica and caucasica) from northeastern Europe. Phylogenies of mtDNA revealed three very old clades (from the early Pleistocene, 1.9 Mya) with a clear geographical signal. Here we analyze a set of 23 autosomal introns, comprising 15,411 nucleotides, in 14 individuals covering the 10 chamois subspecies. Introns offered an evolutionary scenario that contrasts with mtDNA. The nucleotidic diversity was 0.0013± 0.0002, at the low range of what is found in other mammals even if a single species is considered. A coalescent multilocus analysis with *BEAST indicated that introns diversified 88 Kya, in the late Pleistocene, and the effective population size at the root was lower than 10,000 individuals. The dispersal of some few migrant males should have rapidly spread trough the populations of chamois, given the homogeneity of intron sequences. The striking differences between mitochondrial and nuclear markers can be attributed to strong female philopatry and extensive male dispersal. Our results highlight the need of analyzing multiple and varied genome components to capture the complex evolutionary history of organisms.

[Ab] Resumo:Evidence of association between the novel putative border disease virus genotype 8 (BDV-8) and fatal disease in an Alpine chamois (Rupicapra rupicapra) is reported. Diagnostically, we also demonstrated, as already previously reported, the failure of BDV-specific primers (PDB1 and PDB2) to detect BDV-8.

[Ti] Título:Spatial and Temporal Phylogeny of Border Disease Virus in Pyrenean Chamois (Rupicapra p. pyrenaica).

[Ab] Resumo:Border disease virus (BDV) affects a wide range of ruminants worldwide, mainly domestic sheep and goat. Since 2001 several outbreaks of disease associated to BDV infection have been described in Pyrenean chamois (Rupicapra pyrenaica pyrenaica) in Spain, France and Andorra. In order to reconstruct the most probable places of origin and pathways of dispersion of BDV among Pyrenean chamois, a phylogenetic analysis of 95 BDV 5'untranslated sequences has been performed on chamois and domestic ungulates, including novel sequences and retrieved from public databases, using a Bayesian Markov Chain Monte Carlo method. Discrete and continuous space phylogeography have been applied on chamois sequences dataset, using centroid positions and latitude and longitude coordinates of the animals, respectively. The estimated mean evolutionary rate of BDV sequences was 2.9×10-3 subs/site/year (95% HPD: 1.5-4.6×10-3). All the Pyrenean chamois isolates clustered in a unique highly significant clade, that originated from BDV-4a ovine clade. The introduction from sheep (dated back to the early 90s) generated a founder effect on the chamois population and the most probable place of origin of Pyrenean chamois BDV was estimated at coordinates 42.42 N and 1.9 E. The pathways of virus dispersion showed two main routes: the first started on the early 90s of the past century with a westward direction and the second arise in Central Pyrenees. The virus spread westward for more than 125 km and southward for about 50km and the estimated epidemic diffusion rate was about 13.1 km/year (95% HPD 5.2-21.4 km/year). The strong spatial structure, with strains from a single locality segregating together in homogeneous groups, and the significant pathways of viral dispersion among the areas, allowed to reconstruct both events of infection in a single area and of migrations, occurring between neighboring areas.

[Ab] Resumo:High prevalence (46 %) of a gammaherpesvirus was confirmed by molecular detection in the lungs of hunted Pyrenean chamois. The partial glycoprotein B sequence up to the DNA polymerase gene showed 96.6 % nucleotide sequence identity to the Rupicapra rupicapra gammaherpesvirus 1 and 81.5 % to ovine herpesvirus 2. This novel sequence clusters within sequences derived from the malignant catarrhal fever group of viruses, and the corresponding virus is tentatively named Rupicapra pyrenaica gammaherpesvirus 1 (RpHV-1). No specific histological lesions were associated with RpHV-1, nor were any detrimental effects on host health. The epidemiological, phylogenetic and histopathological results suggest that Pyrenean chamois is the natural host of RpHV-1.

[Ab] Resumo:Immune system cell subsets in lymph nodes and spleen from alpine chamois (Rupicapra rupicapra subspecies rupicapra) living in the Italian Alps were characterized immunohistochemically. Seven primary antibodies (against human CD3, CD79αcy, CD68, or ovine CD4, CD8, CD21 and γδ T-cell receptor [TCR] epitopes) were tested on tissues fixed either in formalin or in zinc salts (ZS) and cross-reactivity with chamois immune cell epitopes was shown. ZS fixation allowed wider identification of immune cells, without the need for antigen retrieval. CD4(+) and CD21(+) cells were labelled only in ZS-fixed tissues. Reagents specific for human CD3, CD79 and CD68 antigens successfully detected chamois immune cells, both in ZS-fixed and formalin-fixed tissues. The reactivity and distribution of immune cells in lymph nodes and spleen were similar to those described in other domestic and wild ruminants. Results from this study may allow future investigation of the immune response and pathogenesis of diseases in the chamois.

[Ti] Título:Histological Lesions and Cellular Response in the Skin of Alpine Chamois (Rupicapra r. rupicapra) Spontaneously Affected by Sarcoptic Mange.

[Ab] Resumo:Population dynamics of chamois (genus Rupicapra, subfamily Caprinae) can be influenced by infectious diseases epizootics, of which sarcoptic mange is probably the most severe in the Alpine chamois (Rupicapra rupicapra rupicapra). In this study, skin lesions and cellular inflammatory infiltrates were characterized in 44 Alpine chamois affected by sarcoptic mange. Dermal cellular responses were evaluated in comparison with chamois affected by trombiculosis and controls. In both sarcoptic mange and trombiculosis, a significantly increase of eosinophils, mast cells, T and B lymphocytes, and macrophages was detected. Moreover, in sarcoptic mange significant higher numbers of T lymphocytes and macrophages compared to trombiculosis were observed. Lesions in sarcoptic mange were classified in three grades, according to crusts thickness, correlated with mite counts. Grade 3 represented the most severe form with crust thickness more than 3.5 mm, high number of mites, and severe parakeratosis with diffuse bacteria. Evidence of immediate and delayed hypersensitivity was detected in all three forms associated with diffuse severe epidermal hyperplasia. In grade 3, a significant increase of B lymphocytes was evident compared to grades 1 and 2, while eosinophil counts were significantly higher than in grade 1, but lower than in grade 2 lesions. An involvement of nonprotective Th2 immune response could in part account for severe lesions of grade 3.

[Ti] Título:Detection of Anaplasma phagocytophilum genotypes that are potentially virulent for human in wild ruminants and Ixodes ricinus in Central Italy.

[Ab] Resumo:Human granulocytic anaplasmosis (HGA) is an emerging tick-borne zoonosis worldwide. As is the case for many tick-borne diseases, the epidemiological cycle is associated to the environmental conditions, including the presence of wild vertebrate reservoir hosts, vectors, climate and vegetation. In this study a total number of 87 spleen samples of wild ruminants carcasses from Central Italy, and 77 Ixodes ricinus collected from the same dead animals were screened for Anaplasma phagocytophilum by using Real Time PCR. A. phagocytophilum DNA was detected in 75%, 66.7% and 54.2% of the spleen samples from red deer (Cervus elaphus), Apennine chamois (Rupicapra pyrenaica ornata) and roe deer (Capreolus capreolus) respectively, whereas it was detected in the 31.2% of I. ricinus. A total of 27 positive samples were characterized by sequencing a portion of the groEL gene. Two A. phagocytophilum lineages could clearly be delineated from the phylogenetic tree. Four sequences from red deer, 2 from I. ricinus and 1 from Apennine chamois clustered into lineage I together with those previously described as virulent genotypes related to HGA. The presence of A. phagocytophilum DNA in the Apennine chamois represents the first report for this Italian endemic subspecies.

[Ti] Título:Nocturnal activity of a "diurnal" species, the northern chamois, in a predator-free Alpine area.

[La] Idioma:eng
[Ab] Resumo:The reduction of predation risk is widely considered a major factor affecting the nocturnal activity of mammals. Furthermore, on precipitous mountain terrain, moving in very poor light conditions should be avoided by animals with no special eyesight adaptation to darkness. The Northern chamois Rupicapra rupicapra has been for long considered as a diurnal species, with occasional nocturnal movements. For the first time, we have quantified the nocturnal activity of 21 radiotagged female chamois from the Italian Eastern Alps (Paneveggio-Pale di San Martino Natural Park), continuously monitored for two years from sunset to sunrise, with 24h tracking sessions carried out for six months. Large predators were not present in the study site. Despite their mainly diurnal activity pattern, peaks of nocturnal movements were detected throughout the year. The least proportion of active night fixes occurred in January and in July, while the most were in April and in October. The greater nocturnal activity in the warm months compared to cold periods, was probably due to frozen snow cover reducing nocturnal movements. Movements were mainly concentrated in bright moonlight nights, possibly because of the absence of large predators, but more likely because of increased visibility.
