Etude de l’effet des facteurs du milieu sur la distribution des bactéries entériques dans la lagune de Bizerte (nord -Tunisie)

Bejaoui, B.; Elbour, M.; Belhassen, M.; Mrouna, R.; Boukef, I.; Mejri, S.; Harzallah, A.; Boudabous, A..

La présente étude est effectuée dans le but d’évaluer l’effet des facteurs du milieu sur la distribution des populations bactériennes entériques dans un milieu lagunaire : la lagune de Bizerte. Un échantillonnage saisonnier, (novembre 2004, février 2005, mai 2005 et août 2005), portant sur 41 stations couvrant toute la lagune ont été réalisés. Les analyses bactériologiques effectuées ont concerné l’eau et le sédiment. Les paramètres physico-chimiques de l’eau ont été mesurés in-situ simultanément aux différents échantillonnages. Aussi, les paramètres climatiques ont été fournis par une station météorologique située à proximité de la lagune. Les résultats obtenus ont révélé que les charges en bactéries sont plus importantes dans les sédiments que dans...

Recherche par « RT-PCR » des virus enteriques chez des moules (<Mytilus galloprovincialis>) et des palourdes (<Ruditapes decussatus>)

Abila, R.O.; Omwega, R.N.; Lwenya, C..

Fishing is known to be one of the oldest occupations of mankind and in Lake Victoria (Kenya); it has been largely practiced at artisanal levels. Despite this, poverty amongst the fisher folk remains high. Why the fisher folk remain in perpetual poverty was the key research question for this study. Sampling was conducted on 12 landing beaches between June and August 2004. Data was obtained using survey questionnaires; personal interviews were made using open-ended questions and beach observations. Results from this study indicates that 179 fishers sampled earned an average income of Ksh. 107,063 each in a year with modal income of Ksh. 57,600 while in a day they earned an average income of Ksh. 518 each with modal income of Ksh. 200. Fishers perceived that...

Dans cette étude comparative, deux méthodes d'extraction de quatre types de virus entériques pathogènes pour l’homme (virus de l’hépatite A, l’astrovirus, le norovirus et l’entérovirus) contaminant des moules (Mytilus galloprovincialis) et des palourdes (Ruditapes decussatus) ont été évaluées par l’application de la technique « Perverse Transcriptase- Polymerase Chain Reaction : RT-PCR ». Les échantillons des mollusques bivalves analysés ont été prélevés entre le mois de mars 2000 et le mois de septembre 2001 dans différents sites naturels de la lagune de Bizerte et sans subir l’étape de purification. Les résultats obtenus montrent que le taux de détection des virus par RT-PCR est meilleur lorsque les virus sont extraits à partir de l’estomac et de...

Estudios químicos y bacteriológicos del río Baradero (Argentina): calidad sanitaria del agua y aptitud de los peces para consumo humano

The Health Impacts of Exposure to Indoor Air Pollution from Solid Fuels in Developing Countries: Knowledge, Gaps, and Data Needs

Costagliola, M.; Seigneur, G.N.; Jurquiza, V..

As a result of an agreement signed by the Municipal Government of Baradero Buenos Aires Province, Argentina and the INIDEP, the sanitary quality of the Baradero River waters was studied and fish safety assessed. Results of five field surveys carried out between 1993 and 1997 are studied. Organochlorine and organophosphorate pesticide residues, as well as traces of heavy metals were analyzed in 49 fish specimens and aerobic heterotrophic bacteria (AHB), total coliform bacteria (TC) and fecal coliform bacteria (FC) were counted out in 7 sampling stations placed on the coast and the riverbed. Alpha Hexachlorohexane, gamma Hexachlorohexane, beta Hexachlorohexane, Aldrin, Heptachlor epoxide, pp'DDE and Dieldrin were detected in fish tissues. The values of AHB...

Globally, almost three billion people rely on biomass (wood, charcoal, crop residues, and dung) and coal as their primary source of domestic energy. Exposure to indoor air pollution from the combustion of solid fuels has been implicated, with varying degrees of evidence, as a causal agent of disease and mortality in developing countries. We review the current knowledge on the relationship between indoor air pollution and disease, and on the assessment of interventions for reducing exposure and disease. Our review takes an environmental health perspective and considers the details of both exposure and health effects that are needed for successful intervention strategies. We also identify knowledge gaps and detailed research questions that are essential for...

The process of acquiring an infection has two components: first, exposure through proximity to another infected individual, and second, transmission of the disease. Earlier studies of the socioeconomic factors that affect the probability of acquiring an illness assume uniform exposure to infected individuals and may therefore result in biased estimates. This paper develops an empirical model, consistent with epidemiological models of spread of infections, to estimate the impact of socioeconomic variables on the extent of disease transmission within villages in Cambodia. Data from the 1997 Cambodia Socioeconomic Survey are used in this analysis.

Valdivia, Martin.

El análisis presentado en este documento muestra que la magnitud de las inequidades en salud y en la utilización de servicios de salud en el Perú es muy grande, aun para un país con el nivel de desarrollo del Perú. En consecuencia, se plantea que dichas inequidades deben ser abordadas de manera urgente por investigadores y diseñadores de política, tomando en cuenta que la literatura internacional establece cada vez con mayor contundencia que el crecimiento económico no es suficiente para lograr tal objetivo. La contribución del análisis empírico incluido en este documento al abordaje de la inequidad en salud y en los servicios relacionados con ella tiene dos componentes fundamentales. En primer lugar, se analiza la robustez de los resultados presentados...

To identify interventions which reduce health risks of consumers where highly polluted irrigation water is used to irrigate vegetables in West Africa, scientists worked over 5 years with farmers, market traders and street food vendors in Ghana. The most promising low-cost interventions with high adoption potential were analyzed for their ability to reduce common levels of pathogens (counts of fecal coliforms and helminth eggs). The analysis showed the combination potential of various interventions, especially on-farm and during vegetable washing in line with the World Health Organization (WHO) guidelines. The tested market-based interventions were important to prevent new or additional contamination.

ASYMMETRY IN RAW MILK SAFETY PERCEPTIONS AND INFORMATION: IMPLICATIONS FOR RISK IN FRESH PRODUCE MARKETING AND POLICY

Knutson, Ronald D.; Currier, Russell W.; Ribera, Luis A.; Goeringer, L. Paul.

Scientific evidence clearly indicates that consumption of raw milk carries substantial disease-inducing health risks. While federal U.S. policy mandates that milk moving in interstate commerce be pasteurized; within 41 of 50 states, raw milk can be obtained for consumption. Warning labels notwithstanding, a segment of U.S. consumers pays higher prices for higher-risk raw milk than for either organic or conventional milk. The behavioral factors leading to raw milk consumption are explored. The paternalistic regulatory options for reducing the risk associated with drinking raw milk are identified. Implications for fresh produce sold directly from farms to consumers or through farmers markets are drawn.

The Economics of Alternative Strategies for the Reduction of Food-borne Diseases in Developing Countries: The Case of Diarrhea in Rwanda

von Witzke, Harald; Kirschke, Dieter; Lotze-Campen, Hermann; Noleppa, Steffen.

The paper provides a methodology which is suitable for the analysis of the social cost of disease and the benefits and cost of health intervention by integrating public health analysis and economics. The approach developed in the paper is applied to food-borne diarrhea in Rwanda. The results suggest that simple treatments such as Oral Rehydration Therapy have a higher social rate of return than consumer protection via education.
