Adenoviruses of the most ancient primate lineages support the theory on virus−host co-evolution

The scarcity or complete lack of information on the adenoviruses (AdVs) occurring in the most ancient non-human primates resulted in the initiation of a study for exploring their abundance and diversity in prosimians and New World monkeys (NWMs). In order to assess the variability of these AdVs and the possible signs of the hypothesised virus−host co-evolution, samples from almost every family of NWMs and prosimians were screened for the presence of AdVs. A PCRscreening of 171 faecal or organ samples from live or dead, captive or wild-living prosimians and NWMs was performed. The PCR products from the gene of the IVa2 protein were sequenced and used in phylogeny calculations. The presence of 10 and 15 new AdVs in seven and ten different species of prosimians and NWMs was revealed, respectively. Phylogenetic analysis indicated that the tentative novel AdVs cluster into two separate groups, which form the most basal branches among the primate AdVs, and therefore support the theory on the co-evolution of primate AdVs with their hosts. This is the first report that provides a comprehensive overview of the AdVs occurring in prosimians and NWMs, and the first insight into the evolutionary relationships among AdVs from all major primate groups

Popular movements and Political parties (1986-1996) : the missed reorganization of the political order failing

La chute de la dictature duvaliériste, le 7 février 1986, marque un véritable tournant dans l’évolution politique du pays. La situation nouvelle qui en résulte est généralement analysée ou comprise sous l’angle de l’explication découlant du paradigme des transitions. Ce cadre d’analyse s’est révélé en tous points inadapté pour rendre compte des bouleversements enregistrés. Dès lors, la recherche d’une explication alternative vient à se poser. Cette recherche tente d’explorer cette voie. Et elle soulève un questionnement fondamental qui appréhende la crise haïtienne sous l’angle de l’épuisement de l’ordre politique imposé lors de la première occupation américaine pendant la période 1915-1934. Le défi de cette restructuration du champ politique avait sollicité davantage le rôle et l’action de deux nouveaux acteurs qui ont durablement émergé dans la vie politique du pays à partir des années quatre-vingt : les mouvements populaires et les partis politiques. L’interaction qui s’établit entre ces deux acteurs avait acquis à la fois une dimension complexe et problématique. D’une part, ils (les acteurs) n’avaient pas pu développer une claire conscience de leur rôle dans le processus de transformation politique en cours. D’autre part, il s’est établi entre les deux acteurs un radical antagonisme qui a fini par compromettre la possibilité de construction des capacités politiques nationales en vue de favoriser une évolution positive dudit processus. Le retour à la domination directe américaine, avec l’intervention militaire de 1994, consacrera l’impossibilité de trouver une issue à la crise au plan interne. Cette intervention confirmera la réalité de l’épuisement de l’ordre politique de 1934 tout en provoquant des contradictions nouvelles. Elle a notamment contribué à précipiter la suppression de l’armée, tout en procédant de manière quasi-totale à la confiscation de la souveraineté du pays. Pendant la décennie 1986-1996 qui reste charnière dans le processus de changement politique en Haïti, il n’a pas été possible donc d’aboutir à une redéfinition de l’ordre politique agonisant. Mais l’enjeu de son renouvellement reste indispensable. Malgré leurs faiblesses et les controverses à la base de leur relation, les mouvements populaires et les partis politiques demeurent encore les deux principales formes de représentation politique ou d’action collective qui puissent aider d’avancer dans cette direction. La difficulté majeure est d’arriver à définir l’originalité de l’articulation entre ces deux acteurs qui pourrait bien convenir dans le contexte actuel marqué à la fois par le reflux des mouvements et le faible niveau d’enracinement de la forme partisane.The fall of the dictatorship duvalierist, on February 7, 1986, mark a true turning point in the political evolution of the country. The new situation which results from it is generally analyzed or included/understood under the angle of the explanation rising from the paradigm of the transitions. This framework of analysis appeared in all points misfit to give an account of the recorded upheavals. Consequently, the search for an alternative explanation has been suddenly posed. This research tries to explore this way. And it raises a fundamental questioning which apprehends the Haitian crisis under the angle of the exhaustion of the political order imposed at the time of the first American occupation for the period 1915-1934.

On the one hand, they (actors) had not been able to develop a clear conscience of their role in the process of political transformation in progress.

La lithiase biliaire chez les callithricides (étude bibliographique et enquête auprès des parcs zoologiques européens)

La lithiase biliaire est une affection très fréquente et bien étudiée en médecine humaine. Bien que connue chez les callithricidés, elle a été très peu étudiée chez ces espèces. Cette étude synthétise les connaissances actuelles sur cette affection en médecine humaine et chez les callithricidés afin de faire ressortir d éventuelles similitudes. Dans un second temps, l auteur propose l analyse des résultats d enquête réalisée auprès des parcs européens, à propos de cette affection. Des facteurs de prédisposition à la lithiase biliaire, comme l appartenance au genre Leontopithecus et principalement à l espèce L. chrysopygus, ainsi que des anomalies de conformation de la vésicule biliaire, ont été mis en évidence. Cette étude confirme le caractère pigmentaire des calculs biliaires chez les callithricidés. Elle décrit les signes cliniques et les lésions rencontrées, les moyens diagnostiques et les traitements utilisés ainsi que leurs efficacités. Des conduites à tenir concernant le diagnostic et le choix du traitement sont proposés à la fin de cette étude.NANTES-Ecole Nat.Vétérinaire (441092302) / SudocTOULOUSE-EN Vétérinaire (315552301) / SudocSudocFranceF

Monitoring SARS-CoV-2 Seroprevalence in Domestics and Exotic Animals in Southern France

Since late 2019, Severe Acute Respiratory Syndrome Coronavirus 2 (SARS-CoV-2) has emerged as a significant global threat to public health. Responsible for the COVID-19 pandemic, this new coronavirus has prompted extensive scientific research to comprehend its transmission dynamics, especially among humans. However, as our understanding deepens, it becomes increasingly clear that SARS-CoV-2’s impact goes beyond human populations. Recent investigations have illuminated the transmission of the virus between humans and various animal species, raising important questions about zoonotic spillover events and their potential implications for both human and animal health. Our study set out to investigate the prevalence of SARS-CoV-2 in domestic animals (dogs and cats) and zoo animals in the south of France in 2021 and 2022, covering pre-Omicron and Omicron waves. We identified evidence of SARS-CoV-2 antibodies not only in domestic dogs and cats but also in several mammals in zoos. This study shows the importance of implementing surveillance measures, including serological studies, to identify and monitor cases of SARS-CoV-2 infection in animals

Evolution of Neurological Recovery during the First Year after Subarachnoid Haemorrhage in a French University Centre

International audienceINTRODUCTION: The evolution of neurological recovery during the first year after aneurysmal Subarachnoid Haemorrhage (SAH) is poorly described. PATIENTS: Patients with SAH in one university hospital from March the 1st 2010, to December 31st 2012, with a one-year follow-up. METHOD: Evaluation was performed via phone call at 3, 6 and 12\,months. Primary endpoint was poor neurological recovery (modified Rankin Scale 3-4-5-6), one year after SAH. Secondary endpoints were the incidence of lack of self-perceived previous health status recovery and incidence of cognitive disorders, one year after SAH. Risk factors of poor neurological recovery were retrieved with multivariable logistic regression. RESULTS: Two hundred and eleven patients were included and 208 had a complete follow-up. One hundred and twenty (57.7%) patients were female, 112 (53.8%) had a WFNS grade I-II-III. Seventy (33.6%) patients displayed one-year poor neurological outcome and risk factors of poor outcome were age, baseline Glasgow Coma Score\,≤q\,8, external ventricular drainage, intra-cranial hypertension and angiographic vasospasm. We observed an improvement in good outcome at 3\,months [112 (53.8%) patients], 6 months [127 (61.1%) patients] and one-year [138 (66.3%) patients]. Fifty-nine (35.3%) patients recovered previous health status, 96 (57.5%) had persistent behaviour disorders, and 71 (42.5%) suffered from memory losses at one year. DISCUSSION: Neurological recovery seems to improve over time. The same key complications should be targeted worldwide in SAH patients. CONCLUSION: Neurological complications in the following of SAH should be actively treated in order to improve outcome. The early neuro-ICU phase remains a key determinant of long-term recovery

Evidence of Exposure to USUV and WNV in Zoo Animals in France

International audienceWest Nile virus (WNV) and Usutu virus (USUV) are zoonotic arboviruses. These flaviviruses are mainly maintained in the environment through an enzootic cycle involving mosquitoes and birds. Horses and humans are incidental, dead-end hosts, but can develop severe neurological disorders. Nevertheless, there is little data regarding the involvement of other mammals in the epidemiology of these arboviruses. In this study, we performed a serosurvey to assess exposure to these viruses in captive birds and mammals in a zoo situated in the south of France, an area described for the circulation of these two viruses. A total of 411 samples comprising of 70 species were collected over 16 years from 2003 to 2019. The samples were first tested by a competitive enzyme-linked immunosorbent assay. The positive sera were then tested using virus-specific microneutralization tests against USUV and WNV. USUV seroprevalence in birds was 10 times higher than that of WNV (14.59% versus 1.46%, respectively). Among birds, greater rhea (Rhea Americana) and common peafowl (Pavo cristatus) exhibited the highest USUV seroprevalence. Infections occurred mainly between 2016–2018 corresponding to a period of high circulation of these viruses in Europe. In mammalian species, antibodies against WNV were detected in one dama gazelle (Nanger dama) whereas serological evidence of USUV infection was observed in several Canidae, especially in African wild dogs (Lycaon pictus). Our study helps to better understand the exposure of captive species to WNV and USUV and to identify potential host species to include in surveillance programs in zoos

Filmer, travailler, chercher

Dans le sillage du troisième numéro de la revue qui s’intéressait aux usages et aux statuts des images dans le processus d’enquête, il s’agit ici non seulement de considérer différentes façons de faire de la recherche filmée sur le travail, mais aussi de mettre l’accent sur les effets de la fabrication ou de l’usage de ces données visuelles sur les situations d’enquête), en mettant la focale sur l’utilisation de caméras et d’images animées
