Le cadre propédeutique et donc diagnostique et thérapeutique des infections utérines fait encore débat. Cependant, on peut de plus en plus faire état d’une harmonisation en ces domaines. Elle concerne les critères pour définir de manière aussi précise que possible les 4 types d’infections utérines. Elle concerne également la validation des méthodes de diagnostic. L’antibiorésistance est une réalité. Des mesures pour la réduire sont de plus en plus mises en place. Les praticiens doivent savoir faire un choix de plus en plus raisonné des stratégies thérapeutiques possibles pour limiter les conséquences économiques des infections utérines estimées en 2009 à 1,4 milliards d’Euros. Au terme de la formation, l’apprenant sera capable de… - définir les 4 types d’infections utérines décrites chez la vache - d’en expliquer brièvement la pathogénie - faire le choix propédeutique optimal pour en faire le diagnostic - d’en comprendre les avantages et inconvénients - adapter la stratégie thérapeutique qu’elle soit de nature hormonale ou anti-infectieuse, adaptée à la situation clinique de l’animal [less ▲]

The choice of an antibiotic or antiseptic treatment must take into account, the administrative route, the individual factors (nature of symptoms, stage postpartum, stage in the cycle) and the agents used (nature of germs, minimal inhibiting concentration, pharmacological properties, milk residue). Hormonal treatment is an interesting alternative, which must be considered on an individual basis rather than systematically at herd level. For prevention, it should only be used on animals presenting a high risk factor of infection [less ▲]

Assessing the frequency of metritis shows the animal uterine health as well as the herd . The practitioner prefers to use vaginal examination. The great diversity and variation postpartum in germs responsible for uterine diseases make it difficult to interpret bacteriology. Uterine diseases are all the more frequent as the interval between calving and clinical examination is shorter, therefore the practitioner screening needs to be done as soon as possible. This recommendation is valid for the primiparous dairy cow as well as the suckler cow [less ▲]

Epizootic rabbit enteropathy (ERE), a highly lethal (30-80% mortality) disease of broiler rabbits aged 6-14 weeks, first appeared in 1997 in French intensive enclosed rabbitries and is of unknown aetiology. Bacteriological, virological and parasitical examination of the intestinal contents of rabbits that had died either in spontaneous field cases or after experimental reproduction of ERE, were undertaken in an attempt to identify infectious agents that may play a role in the disease. Two bacterial strains, Clostridium perfringens and non-enteropathogenic Escherichia coli, were repeatedly isolated at high faecal counts from naturally infected animals. In field cases, a correlation between typical gross lesions of epizootic enteropathy and the presence of the alpha toxin of Cl. perfringens was observed (P < 0.0001; Chi-squared test). Although attempts to reproduce the disease by inoculation with different pools of cultivable bacterial strains failed, the disease was successfully reproduced by inoculation with one French and two Belgian samples of caecal contents.

Sixty-six rabbits, with no history of vaccination against myxomatosis and which had died of pulmonary lesions, were submitted for virological and serological tests for Myxoma virus (MV) infection and for bacteriological examinations. At post mortem, the diagnoses based on observed lesions were as follows: acute haemorrhagic pneumonia (38%); acute suppurative bronchopneumonia (35%); and fibrinohaemorrhagic bronchopneumonia with fibrinous pleuritis (27%). MV was isolated from 10% of the rabbits, mainly from those with acute haemorrhagic pneumonia. Serological evidence of MV infection was demonstrated in 44% of rabbits. Pathogenic bacteria species isolated from lungs were Pasteurella (spp. and multocida), Escherichia coli, Bordetella bronchiseptica and Pseudomonas aeruginosa, respectively, from 41, 11, 7 and 6% of samples. No relationship could be established between the presence of specific antibodies to MV and the observed pulmonary lesions or the results of the bacteriological examinations. A significant trend was established between the severity of the lesions and the results of the bacteriological examinations. [less ▲]

Infective endocarditis remains an important problem and the means of prevention are still insufficient. The causal bacteria have changed very little, but the incidence of nosocomial infections and endocarditis complicating intravenous drug abuse are increasing. The distinction between subacute and acute clinical presentations remains appropriate. Cardiac and neurological complications are frequent and carry a high risk of mortality. The diagnosis is obtained by the integration of clinical data and the results of blood cultures. Echocardiography is extremely useful for detecting vegetations, and for assessing the haemodynamic consequences and specific cardiac complications. Risk stratification can be obtained by correct integration of multiple parameters. The causal agent should be identified before the initiation of antimicrobial therapy. Surgery is frequently required, and should be performed rapidly when indicated. [less ▲]

Les norovirus sont reconnus comme étant une cause majeure d’épidémies de gastroentérites chez l’homme. Les mutations ponctuelles et la recombinaison sont les mécanismes moléculaires moteurs de l’évolution des norovirus. La recombinaison peut créer des modifications considérables dans les génomes viraux. Nous avons récemment obtenu un norovirus murin recombinant (RecMNV) après coinfection in vitro de souches homologues de norovirus murins. Le RecMNV présente une aptitude (fitness) réduite à la réplication. L'infectivité du RecMNV a été d’abord évaluée in vivo et ses adaptations réplicatives et génétiques ont été ensuite suivies au cours de passages en série in vitro. Durant l'infection in vivo, le RecMNV a été comparé aux souches parentales chez des souris Balb/cByJ par la mesure du poids corporel et l'estimation de la charge virale par RT-qPCR. Le poids des souris infectées par RecMNV était généralement plus élevé que celui des souris infectées par les souches parentales. Des charges virales ont été détectées dans tous les organes examinés, suggérant que, comme les souches parentales, le RecMNV peut se propager au-delà du tube digestif pour produire des infections systémiques. Ensuite, les générations de RecMNV résultant du premier (RecE) et du dixième (RecL) passages in vitro ont été comparées et leurs séquences déterminées. RecL a montré une augmentation significative du diamètre des plaques de lyse et une cinétique de réplication plus rapide que RecE. L'analyse moléculaire a montré plusieurs modifications de la séquence nucléotidique et en acides aminés entre RecE et les souches parentales ainsi qu’entre RecE et RecL. Ces résultats suggèrent que la recombinaison se produisant in vitro entre des souches de norovirus murins homologues peut générer une souche chimère, qui présente des propriétés biologiques similaires aux souches parentales et est capable d'une infection productive in vivo. De plus, ils montrent l'adaptation virale et la récupération de la réplication virale in vitro après un événement de recombinaison. [less ▲]

The clear detection with CoRoT and Kepler of radial and non-radial solar-like oscillations in many red giants paves the way to seismic inferences on the structure of such stars. We present an overview of the properties of the adiabatic frequencies and frequency separations of radial and non-radial oscillation modes, highlighting how their detection allows a deeper insight into the properties of the internal structure of red giants. In our study we consider models of red giants in different evolutionary stages, as well as of different masses and chemical composition. We describe how the large and small separations computed with radial modes and with non-radial modes mostly trapped in the envelope depend on the stellar global parameters and evolutionary state, and we compare our theoretical predictions and first Kepler data.Finally, we find that the properties of dipole modes constitute a promising seismic diagnostic of the evolutionary state of red-giant stars.

Many biological, physical, chemical, economic, and social phenomena are dynamic and are modeled using (systems of) Ordinary Differential Equations (ODEs). But a more realistic way to describe these dynamics relies on Discrete Time Markov Chains (DTMC). There is a growing interest in the development of Bayesian statistical methods to infer on the parameters in such dynamic models, particularly those defining epidemic spread, by combining prior information with experimental or observational data. Our proposal aims to explore the merits of the Bayesian Optimal Filtering technique in the estimation of the parameters of a stochastic SEIR (S = Susceptible, E = Exposed, I = Infectious, R = Removed) epidemic model. State Space Models (SSMs) are used to describe the epidemic dynamic. The unknown static parameters are estimated using a combination of Sequential Monte Carlo techniques with a Markov Chain Monte Carlo algorithm, . . . [less ▲]
