“…These factors play a key role in the invasion and intracellular proliferation in animal tissues. The use of the PCR method enables identification a number of genes specific for L. monocytogenes species, such as hly, iap, prs, prfA, flaA, and actA (3,8,10,13,15,17,21).…”

Introduction: The aim of the study was to optimise and compare two multiplex PCR assays for the detection of Listeria spp. and Listeria monocytogenes in biological samples including the liver, brain, and blood. Material and Methods: Three strains of L. monocytogenes and single strains of each of the species:welshimeri, and L. seeligeri were used. Additionally, five other species of bacterium were used to evaluate the specificity of the tests. Results: Specific amplification products were obtained for both multiplex PCR assays, which confirmed the tested strains as Listeria spp. and L. monocytogenes, respectively. Isolates of other species did not yield PCR products. Conclusion: Both multiplex PCR assays proved to be significantly sensitive and highly-specific methods for the detection of Listeria strains.

“…Listeriosis has a very low incidence, but with a high case fatality rate that can exceed 30% [13]. Recently, several European countries are experiencing an apparently increasing incidence of listeriosis, mainly amongst persons aged 65 years and older [20].…”

Chemical Composition and Antibacterial Potential of Artemisia arborescens L. Essential Oil

This study was undertaken to characterize the essential oil (EO) of Artemisia arborescens growing wild in Sicily. EO, extracted by steam distillation, was examined for its chemical composition and for its capability to inhibit some food-borne pathogen bacteria. A total of 43 compounds (13 monoterpene hydrocarbons, 14 oxygenated monoterpenes, 10 sesquiterpene hydrocarbons, three oxygenated sesquiterpenes and less amount of other three compounds), which account 93.73% of the total oil, were identified by gas chromatography and gas chromatography-mass spectrometry. Oxygenated monoterpenes (57.32%) constituted the main fraction, with b-thujone as the main compound (45.04%), followed by the sesquiterpene hydrocarbon chamazulene (22.71%). Undiluted EO showed a large inhibition spectrum against strains of Listeria monocytogenes (34 out of 44), whilst it was ineffective against enterobacteria and salmonellas. The minimum inhibition concentration (MIC) was evaluated for the two most sensitive strains (L. monocytogenes 186 and 7BO) at two cellular concentrations (10 6 and 10 7 CFU ml -1 ). The lowest MIC (0.625 ll ml -1 , dilution of oil with acetone) was found for strain L. monocytogenes 186 at 10 6 CFU ml -1 .

“…The susceptibility to and severity of many foodborne diseases increases with age: e.g. the increase in listeriosis cases noted in several EU countries in recent years has been seen mostly in the elderly population (Denny and McLauchlin, 2008;Goulet et al, 2008), and the proportion of Campylobacter cases requiring hospitalisation has increased markedly in the patients over 75 years old (Gillespie et al, 2005). The reasons for the increased severity and susceptibility are not fully understood but are likely to include a lowered efficiency of the immune system and oxidative damage leading to ageing and increased vulnerability to diseases related to the occurrence of cellular damage for instance due to the action of reactive oxygen species.…”

Current and potential future trends in technology, consumption and trade of food that may impact on food-borne disease are analysed and the key driving factors identified focusing on the European Union and, to a lesser extent, accounting for the United States and global issues.Understanding of factors is developed using system-based methods and their impact is discussed in relation to current events and predictions of future trends. These factors come from a wide range of spheres relevant to food and include political, economic, social, technological, regulatory and environmental drivers. The degree of certainty in assessing the impact of important driving factors is considered in relation to food-borne disease. The most important factors driving an increase in the burden of food-borne disease in the next few decades were found to be the anticipated doubling of the global demand for food and of the international trade in food next to a significantly increased consumption of certain high-value food commodities such as meat and poultry and fresh produce. A less important factor potentially increasing the food-borne disease burden would be the increased demand for convenience foods. Factors that may contribute to a reduction in the food-borne disease burden were identified as the ability of governments around the world to take effective regulatory measures as well as the development and use of new food safety technologies and detection methods. The most important factor in reducing the burden of food-borne disease was identified as our ability to first detect and investigate a food safety issue and then to develop effective control measures. Given the global scale of impact on food safety that current and potentially future trends have, either by potentially increasing or decreasing the food-borne disease burden, it is concluded that a key role is fulfilled by intergovernmental organisations and by international standard setting bodies in coordinating the establishment and rolling-out of effective measures that, on balance, help ensure long-term consumer protection and fair international trade.
