Full textWe used an experimental method in the framework of the theory of expected utility to evaluate the attitudes to risk in a group of Iranian and compare with a French group. We also measured various characteristics of individual perception of risk of HIV infection, sexual behavior and life expectancy, which appear to be related to attitudes toward risk. We found that participants with higher perceived risk of HIV infection and HIV-positive participants, compared to others, are more attracted to risk in their behavior. We also found that the Iranian group, compared with the French group, is more tolerant of risk even if they seem to be widely informed about the risks of HIV infection. If these preferences postpone on sexual behavior, as this study suggests, they complicate the prevention of HIV, because only ignorance would not cause the spread of HIV. For this reason, focus on information alone is not sufficient in preventing AIDS. While risky sexual behavior is associated with a high risk preference, change these preferences could contribute to AIDS prevention

Full textFactors associated with influenza virus transmission and susceptibility to infection still remain not well understood. The risk for infection can be considered as the result of an interaction between factors linked to the pathogen, the host (including the immune system) and the characteristics of exposure (environmental parameters and interhuman contacts). The emergence of the novel A/H1N1 virus, causing the 2009 pandemic, had offered a promising research opportunity to study the determinants usually associated with influenza infections in general and in particular regarding a virus for which the susceptibility of the population was very variable and linked with previous exposure of subjects to viruses that were genetically close. To study influenza infections and their determinants, a cohort of 601 households (1450 subjects) in the French general population was established in late 2009 using a multidisciplinary approach. The follow-up of this cohort, which involves the collection of biological samples and an active tracking of influenza-like symptoms, notably consists of a detailed collection of clinical and epidemiological data (including information regarding the subjects’ environment, their contacts, and their risk perception likely to impact their behavior). The analysis of this massive database offers a novel opportunity to study the risk of infection as a result of a complex interaction of factors which have previously been studied separately. This project implicated the use of new analytical methods, inspired by the “omics” approach already used for the simultaneous study of a large number of covariates

Full textPour identifier les espèces vectrices, nous avons conduit des captures sur appâts oiseau, cheval et homme de mai à octobre 2004, recherché le VWN chez les moustiques capturés et réalisé des infections expérimentales des candidats vecteurs. Pour estimer le risque d'infection, la formule de la capacité vectorielle a été généralisée à plusieurs espèces d'hôtes et de vecteurs et spatialisée. Une démarche pour l'estimation spatio-temporelle des densités de vecteurs a été proposée, en se basant sur des modèles de dynamique de population et sur une cartographie des milieux propices au développement larvaire et au déplacement des vecteurs.
Les conclusions de cette étude sont que Culex modestus Ficalbi est sans doute le principal vecteur enzootique (transmission au sein des populations d'oiseaux) et épidémique (transmission des oiseaux aux mammifères) du VWN dans les zones humides. Sa distribution doit être précisée pour estimer l'importance de son rôle en zone sèche. Culex pipiens L. est sans doute un vecteur enzootique important dans l'ensemble de la Camargue et le principal vecteur épidémique en zone sèche, où les déterminants génétiques ou environnementaux de ses préférences trophiques restent à éclaircir. Enfin, les principales espèces d'Aedes et Anopheles n'ont sans doute qu'un rôle mineur dans la transmission du VWN.

Full textSalmonella is a zoonotic bacterium that represents a public health burden all over the world. Pig is considered as one of the main reservoir of this pathogen. The goal of this research project was to identify the main measures that would limit the presence of Salmonella in the Reunionese pig production. Nearly 80% of the pig farms investigated were infected with Salmonella at the end of the fattening period. This asymptomatic infection was associated with several risk factors: geo-climatic conditions (altitude and rainfall), poultry production on the same site, the size of the farm and the presence of residual Salmonella in rooms before the loading of the pig batch. Furthermore, the longitudinal investigation highlighted that environmental residual Salmonella were the main source of infection whether at farm, during the transport and the lairage of pigs. These results strengthen the importance of improving efficiency of cleaning and disinfection procedures. The wild fauna of Reunion Island seems to be involved in the epidemiology of Salmonella in the pig production, since high genetically relationships were observed between Salmonella strains isolated from rodents and cockroaches and those isolated from pigs. Otherwise, our study also highlighted Salmonella prevalence of 16.5% in pork sausages demonstrating that Salmonella in the pig production may represent a risk for public health in Reunion Island. These works stress the need to act at each stage of the pig production. Moreover, a global effort has to be considered, including professionals of the different animal production, industrials, veterinary and health services and authorities

Full textMadagascar is part of endemic region of HBV. Distribution is different in rural and urban area. The historic of human settlement and its insularity might impact distribution and molecular characteristic of HBV in Madagascar, we then supposed that difference observed in distribution and prevalence of HBV were due to viral variability and different pattern of viral transmission. Therefore, the main objective of this thesis was to determine molecular and epidemiological pattern that may influence dynamic transmission and complications of infection. Results: weighted prevalence of HBsAg was 6.9%. It varied from 3% to 26% according to area of sampling. Populations with a low socio-economic status and those living in rural areashad a significantly higher seroprevalence of HBsAg. Gene flow study showed rural area remain important in virus diffusion.HBV infection was found to be responsible of 31% of chronic liver disease encountered in the main public hospital in the capital of the country. Because of its recent emergence, its introduction dated from XIX century during colonization period. Its expansion during 1980s might be due to use of unsafe injection material mainly during malaria epidemic. Conclusion: The result of these work allowed us to advocate for a policy of struggle, in particular in the very remote areas of the island where the HBsAg prevalence is the most important and where care and preventive measures such as vaccinations are scarce
Bocher, Aurélie. "Défenses immunitaires et division du travail chez les fourmis." Paris 6, 2007. http://www.theses.fr/2007PA066294.
Full textImmune defence is a fundamental trait determining fitness in social insects, both by increasing individual survival and by limiting contamination at colony level. We investigated how individual variation in immune defence, which is a costly trait, is related to division of labour concerning reproduction or sterile tasks. Indeed, the different worker functions within the colony may be associated to distinct selection pressures and thus induce a variation in immune defence. Reciprocally, including immune defence as a life-history trait can help to understand some aspects of social evolution. Ants offer interesting models to address these questions. Firstly, we studied the effects of reproductive conflicts on labour and immune defence in a queenless ant, Diacamma sp. From Nilgiri. The groups affected by conflicts showed a lower rate of labour and an immunosuppression, suggesting a cost of reproductive conflicts. Secondly, we investigated the levels of phenoloxidase (PO) and prophenoloxidase (PPO), two major enzymes of the insect immune system, in workers of the ant Cataglyphis velox. We found a higher PO activity in foragers than in intra-nidal workers, which could result from an adaptive up-regulation of PO in foragers in relation to the high risk of infection and wounding outside the nest. Finally, we hypothesized that inactive workers, often observed in social insect colonies, may invest more resources in immune defence. We conducted a behavioural and immunological study in Cataglyphis velox to analyse the relation between inactivity and immune defence. Our hypothesis was not supported but could be further studied by measuring other immune parameters. This work suggests that division of labour may influence the intra-colonial immune variation and highlights the importance of considering immune defence for the study of social insects

Full textThe aim of this work was to 1) determine a marker for the risk of prematurity and of prenatal infection in women with preterm labour 2) design a simple, fast, non-invasive test that allows to test this marker. In case of preterm labour, we demonstrated, in a first step, the association of mRNA detection of IL-6 and IL-8 in vaginal secretions with preterm birth (for IL-6) and neonatal infection (for IL-6 and IL-8). In a second step we assayed IL-6 with a new immunochromatographic bedside test. The results were correlated with those of IL-6 mRNA in vaginal secretions, and predicted preterm birth in a population of women with preterm labour and intact membranes. Accordingly, to access the value of this new test for the diagnosis of neonatal infection, we performed a prospective study in a population of women with PPROM. This prospective clinical study included 73 patients. IL-6 protein in vaginal secretions was determined with an immunochromatographic bedside test. The sensitivity of Il-6 for predicting neonatal infection was 79 % (95 % CI : 65-92), its specificity 56 % (95 % CI : 42-70), it's positive predictive value 30 % (95 % CI : 12-47), and its negative predictive value 92 % (95 % CI : 84-99)
