Optimisation du protocole de recherche des Escherichia coli producteurs de Shiga-toxines (STEC) dans les aliments

2011

Enterohemorrhagic Escherichia coli (EHEC) are an important subset of Shiga toxin–producing E. coli (STEC) associated with foodborne infections. These bacteria can cause hemorrhagic diarrhoeal disease and Haemolytic and Uremic Syndrome which are associated with some predominant serotypes defined by AFSSA institute: O26, O103, O111, O145 and O157.Cattle are the primary reservoir of STEC. Although STEC transmission to humans is frequently associated with consumption of meat, dairy products have also been implicated in human cases. Sensitive and rapid detection methods for STEC are essential for the food industry to ensure a safe food supply. However, the detection of STEC in foods is problemat…

Effects of modulation of body fat in production of adiponectin in mice : consequences on hepatic metabolism of lipids

2010

Adiponectin (ApN), a 30-kDa adipokine abundantly produced by adipose tissue has been described for the first time in 1995. Early findings demonstrating serum adiponectin levels are inversely correlated with obesity initiated intense investigation of the relationship between adiponectin and all symptoms of the metabolic syndrome. Of these studies, strong evidence suggests that a weight loss induced by medication or hypocaloric diet led to increased circulating ApN levels and improvement of biochemical parameters. Thus, high levels of ApN have been correlated with an improvement of insulin sensitivity and lipid parameters reducing cardiovascular risk. However mechanisms involved in the improv…

Sapotrophical development of fusarium graminearum : respective role of different natural habitats of the fungus in the wheat infectious process in Bu…

2012

Fusarium Head Blight (FHB), mainly caused by the fungal species Fusarium graminearum, is one of the most important disease altering wheat crops in Burgundy. Moreover the plant-pathogen interaction leads to the production of mycotoxins potentially toxic for humans and animals.The only alternative to date to prevent the development of the disease is to control the saprotrophic development of F. graminearum in its natural habitat, i.e. weeds, soil and crops residues. Due to the trend of reduced tillage, special attention should be paid to the role of crop residues in the survival and development of F. graminearum.Two approaches were chosen to better understand the saprotrophic development of F…

PROFITABILITY OF SMALL LOQUAT FARMS IN SICILY

2015

The northern Sicilian coastline, known for its favorable soil and climatic conditions, represents the main production area in Italy for loquat (Eriobotrya japonica Lindl.). Over the years, the absence of process innovation and appropriate marketing strategies caused a gradual decline of loquat cultivation. This study estimates the profitability of some representative Sicilian farms that grow loquat in the area of Trabia (Palermo Province), where this crop is important for the local economy. The results highlighted a productive scenario characterized by high production costs, where only a family farm that supplies much of its own labor can survive.

Aspetti economici e commerciali dell'arancia di Ribera

2010

The Sicily is the first region for orange cultivation in Italy. This sector, throughout the ages, has been characterized by a decrease of the invested areas and by a reduction of the fresh product’s demand; in the meantime, the competitiveness of the new producer countries is increased for a better commercial organization and for lower production costs. The aim of the paper is to improve the knowledge of orange cultivation in Ribera area, in the province of Agrigento (Sicily). It is carried out a microeconomic analysis on a sample of 20 farms to determine profitability of orange cultivation by means of various economic indicators (production costs, profits, net incomes). The business survey…

Adapting to High Temperatures: Effect of Farm Practices and Their Adoption Duration on Total Value of Crop Production in Uganda

2021

In this article, we use spatially granular climate data merged with four waves of household survey data in Uganda to examine empirically the relationships among high temperatures, total value of crop production, and the adoption and adoption duration of two sustainable agricultural practices (organic fertilizer adoption and maize–legume intercropping). We do this using a fixed-effect model with instrumental variables to address potential endogeneity issues. Our findings indicate that the adoption of these practices has a positive effect on the total value of crop production, and such effect increases monotonically as temperatures increase from long-term averages. Moreover, the number of yea…

La filiera siciliana della pasta: un'applicazione della netchain analysis

2016

The system of Sicilian durum wheat is facing, as indeed is happening to the entire food system, the evolution of consumption patterns toward higher quality requirements: health-wise, primarily, but also including some intangible requirements. Recent acquisitions in the field of healthy food, have called attention to some specific characteristics of Sicilian durum wheat. The durum wheat sector represents a major landmark for regional agriculture, being by far the most widespread arable crop in Sicily; a crop that, over the past 30 years, has evolved considerably, due to the impact of EU regulations. Currently, the whole Sicilian cereal-pasta chain shows shortcomings in organization and size,…
