Повний текст джерелаBackyard poultry farming involving for example traditional family flocks and hobby poultry flocks is an important sector of the French poultry production. Today, it is estimated that they represent 2.5 million owners, and they are suspected of transmitting pathogens to commercial poultry farms (and/or humans). In this study, we investigated the role of backyard poultry flocks in the circulation and transmission of pathogens to commercial poultry farms. In order to better characterize the stakeholders in the backyard poultry sector, a national participatory survey was conducted to analyze owners' practices and identify different sub-populations. Simultaneously, the prevalence of 14 pathogens of interest in human and/or animal health and predominantly presenting a respiratory tropism were studied. The identification of pathogens as markers of infection and transmission was carried out by comparing their prevalence levels in the familial and commercial poultry sectors. In the familial poultry sector, five sub-populations were identified: urban poultry, traditional poultry, student poultry, "pet" family poultry, and hobby poultry. Pathogens such as Mycoplasma synoviae and Avibacterium paragallinarum are highly prevalent in French family poultry flocks but are rarely identified in commercial farms. Consequently, they could be considered as relevant markers of transmission from backyard to commercial flocks. In general, the results indicate the limited role of backyard poultry flocks in the contamination of commercial poultry farms. On the contrary, human links existing between backyard and commercial premises were identified as a risk factor for backyard flocks in an epizootic avian influenza context. These results lead us to consider the reverse hypothesis of a possible pathogens transmission from commercial to backyard poultry flocks during epidemics

Повний текст джерелаHealth surveillance is defined as the production and processing of data aimed at informing health risk mitigation programs. Surveillance of infectious animal diseases is usually considered as a public good, involving the responsibility of the state. Surveillance of transboundary emerging diseases, like HPAI, is even perceived as an international public good, justifying information sharing between countries. The most common type of surveillance, i.e. passive or reactive surveillance, is based on communications from private or public actors of the information they hold about the health status of animal populations they observe to authorities in charge of health surveillance. Animal health is therefore confronted with the problematic of public goods whose production depends on decentralized private decision. Two questions may be raised: what are the factors influencing the decision to transmit information to public surveillance systems? Are these factors solely of monetary nature or are they linked with other types of issues, among which the social environment of individuals, the place where they live and their power relationships? Another question relates to the existence of information networks established between private and public actors which enable to a part of the population of sanitary threats. How these are networks constituted? To which extent are they linked with public surveillance systems? Which type of risk management do they allow? The studied case is H5N1 HPAI in domestic poultry in Southeast Asia. A study was conducted in four areas of limited spatial scale distributed in two countries, three in Viet Nam and one in Thailand. Graph theory was applied to the diffusion of information related to HPAI suspicions between actors, private or public. The structure of these networks is shaped by the political organization of rural places, the villages, and by the value chains to which poultry farms belong. In study areas of Viet Nam with widespread commercial poultry farming, upstream actors of the value chain, supplying feed and veterinary products to farmers have better access to information from the commercial and backyard poultry farms. In the Thailand study area, actors participating in cock fighting games have a better access to information from backyard farms. These actors who are central in information networks facilitate the spatial spread of information and access of farmers to information from distant locations. Veterinary authorities are included in the information networks but their attributed priority is week in comparison with private actors of value chains. Besides, qualitative and semi-quantitative interviews were conducted, using tools of participatory epidemiology, in order to identify issues linked with suspicion reporting to veterinary authorities. Those issues differ according to places and types of poultry production. They go beyond purely monetary concerns: sanitary risks and environmental nuisances to the neighborhood, responsibility in economic losses of other farmers and commercial partners and social and affective value of animals are potential components of the decision of farmers to report a suspicion to veterinary authorities. A part of these issues are linked with disease control measures implemented by the state in response to sanitary risks. However, others are strictly associated with information spread. It is the case, for example, of impacts of information on poultry market prices

Повний текст джерелаAntimicrobial resistance is now well recognized as a global and major public issue, and as such has been tackled through antibiotic stewardship. Decreasing antimicrobial use is a great challenge for livestock farming, especially for intensive production systems, which were among the more exposed in 2013. It is of great interest to search for drivers enabling to reduce antimicrobial use. The thesis objectives were thus to identify drivers for change, in an organized production system: Label Rouge traditional free-range broiler farming. A multi-disciplinary approach, combining sociology with epidemiology was used.First, a sociological study based on semi-directive interviews with farmers, production technicians and veterinarians was carried out in order to study professionals’ perceptions and practices related to antimicrobial use. Results highlight the adequacy between the imperative of decreasing antimicrobial use and farmers’ professional identity. Besides technical improvements, the coaching of farmers by counsellors whom they trust was also found to play an important role in changing their practices towards lower antimicrobial use.Second, a pharmaco-epidemiological case-control study was carried out. 260 flocks of broilers were investigated thanks to on-farm questionnaires, in order to identify the factors associated with antimicrobial use. Preventive technical tools such as herbal drugs or chicken paper were associated to a decreased use of antimicrobials. The way farmers judge their flock health was also significantly associated to antimicrobial use.Finally, a sociological study involving semi-directive interviews with directors and production technicians from three farmer organizations enabled to study the strategies developed by farmer organizations to reduce antimicrobial use. We found that the studied farmer organizations had various and relatively new approaches, which are hardly ever constituted of tools specifically designed to decrease antimicrobial use. Only one approach was a real and complete strategy, mostly based on organizational tools aiming to enroll the actors and coordinate the networks and have them apply the technical tools. The study shows that some farmer organizations can play an important role in antimicrobial use reduction, thanks to the different drivers they have to encourage farmers to change their practices.The combination of sociological and epidemiological approaches used in this study enabled to highlight a wide range of drivers for antimicrobial use in broiler breeding. This study also raises further questions on the role played by private stakeholders – such as distributors - in animal health in general, and antimicrobial use in particular

Повний текст джерелаBiosecurity compliance issue is present in all types of animal productions, Therefore, it is essential to define strategies to improve the implementation of biosecurity measures. This study described the application of biosecurity measures when entering and exiting 24 poultry barns in Québec, Canada. The effect of audits and visible cameras on compliance was investigated, as well as determinants of compliance. Also, the relationship between compliance and personality profiles, experience and education has been described. Application of biosecurity measures was evaluated using hidden cameras. Short term (first two weeks) and medium term (six months later) compliance were determined. Based on the control group, 44 different biosecurity breaches were observed when getting in and out of poultry barns. Most were related to area delimitation (clean versus contaminated). The nature and frequency of errors suggest a lack of understanding of biosecurity principles. Overall, video viewing revealed 3055 visits done by 277 different individuals (136 employees, 123 visitors, 3 supervisors and 15 growers). Results showed that audits did not have any impact on employee compliance. Visible cameras had a significant impact on changing boots and respecting areas during the visit for the short term period. However, six months later, compliance significantly declined and was no longer statistically higher compared to the control group. Duration and moment of the visit, presence of the grower or an observer, barn entrance design, number of barns, number of biosecurity measures requested, type of boots, gender and being a member of a grower’s family were significantly associated with compliance with some biosecurity measures. Finally, three personality traits were significantly associated with compliance: responsibility, action-oriented and complexity, as well as the number of years of experience and the level of education. There is a need to improve biosecurity training by making training material available to all poultry personnel demonstrating why and how to apply biosecurity measures. Educational meetings should also address issues related to visit and farm characteristics. Improving barn entrance design should contribute to enhance and maintain compliance. The identification of personality traits associated with compliance may have implications for the selection of job applicants or task attribution, and for developing educational materials and training programs.

Повний текст джерелаCampylobacteriosis is a leading cause of acute bacterial gastro-enteritis in industrialized countries. The epidemiology of the disease is complex, involving many sources and transmission pathways. The principal objective of this project was to study environmental factors and methodological aspects pertinent to the spatial epidemiology of human campylobacteriosis using cases reported in Quebec (Canada) between 1996 and 2006. A conceptual diagram of sources and transmission pathways of Campylobacter was first proposed following a synthesis of current epidemiological knowledge based on a comprehensive literature review. The risk of recurrent episodes in relation to patient characteristics was described. Life table estimates and logistic regression were used for modeling. Compared to campylobacteriosis risk in the general population, the risk for a recurrent disease event was higher for a period of four years with a decreasing trend. This increased risk was similar across gender but higher for people from rural areas and lower for children under four years old. These results may suggest the absence of durable immunity or clinical resilience following a first episode and/or periodic re-exposure, at least among reported cases. Next, criteria were proposed and applied to ascertain the best geographical unit to use. Nine measurable criteria were proposed, including biological relevance, communicability of results, ease of data access, distribution of exposure variables, cases and population, and unit shape. These criteria were applied to various geographical units derived from administrative, health services and natural frameworks. Ultimately, the municipal geographical unit performed the best, given the specific objectives of the study. Future research areas for optimizing the choice of geographical unit were discussed. Another objective was to estimate and compare the associations between incidence and various environmental characteristics (poultry density, ruminant density, slaughterhouse, temperature, and precipitation) and demographic characteristics (population density, diploma) using seven different geographical units. Conditional autoregressive models were used for statistical modeling. In general, the number of significant predictors decreased as the aggregation level increased but directions of associations were consistent. More aggregated scales tended to show larger but more variable estimates for all variables, with the exception of the presence of slaughterhouses. This study highlighted the need for careful selection and analysis of geographical units when using ecological designs in epidemiological studies. Finally, the association between environmental characteristics and incidence in relation to four age groups and deux seasonal periods was studied. A multi-level Poisson regression model was used for modeling at the municipal level. High ruminant density was positively associated with incidence but decreased with age. High poultry density and presence of a large poultry slaughterhouse were also associated with higher incidence for people aged 16-34. Associations were also detected with population density and average daily precipitation. Except for population density, associations were constant across seasonal periods. Close contact with farm animals is most likely involved in the associations observed. Clearly, age and season must be considered in future studies on campylobacteriosis and in the design of preventive measures.
