Bacteriophages are an attractive tool for application in the therapy of bacterial infections, for biological control of bacterial contamination of foodstuffs in the alimentary industry, in plant protection, for control of water-borne pathogens, and control of environmental microflora. This review is mainly focused on structures governing phage recognition of host cell and mechanisms of phage ad...

Over a 9-month period, 14 strains of Ralstonia pickettii were isolated from various biological samples inoculated in a blood culture medium. Molecular epidemiological investigation confirmed the relatedness of the strains. The source of the contamination proved to be the blood culture bottle caps.

background; foods have been many changes from production to tables and continuous control is necessary to maintain food safety and supply foods with good quality. the aim of this study was to evaluate the quality of some foods with high consumption in zanjan city during the 5 years from 2009 to 2013. methods; in a case-control descriptive study with an annually control program during 5 years fr...

An in-depth study was carried out in Rajapur, an arsenic-affected village in West Bengal, India, to determine the degree of groundwater contamination with arsenic and the impact of this contamination on residents. The flow injection hydride generation atomic absorption spectrometry (FI-HG-AAS) method was used to measure arsenic concentrations in water and biological samples. Dermatologists reco...

This paper is on the biological impact of arsenic and antimony on the flora and microflora on a former Sbmining site in Schlaining (Stadtschlaining, Burgenland, Austria). Several habitats were investigated with respect to biodiversity and metalloid contamination in soil. Although the overburden of the mining activity had been remediated less than ten years ago, metalloid concentrations occurred...

We study the question of auction design in an IPV setting characterized by ambiguity. We assume that the preferences of agents exhibit ambiguity aversion; in particular, they are represented by the epsilon-contamination model. We show that a simple variation of a discrete Dutch auction can extract almost all surplus. This contrasts with optimal auctions under IPV without ambiguity as well as wi...

An overview of spin contamination and its relationship to broken-symmetry wave functions are presented. Spinoperator expectation-value formulas are developed for use with generalized, unrestricted, and restricted spin orbitals. Currentprojection techniques are reviewed and illustrated for a variety of current theoretical methods.

The development of Aspergillus flavus inoculation techniques has played an important part in developing corn (Zea mays L.) germplasm resistant to aflatoxin contamination. Corn genotypes evaluated for aflatoxin resistance in field studies must be artificially inoculated due to the sporadic nature of aflatoxin contamination from year to year. A number of different inoculation techniques are used ...

During the previous survey year (Year 2), a methodological issue arose which meant that our measures were no longer providing a reliable indication of how levels of contamination in chickens at retail were changing over time, or providing like for like comparisons between retailers. This methodological issue is explained in the January-March 16 report: www.food.gov.uk/sites/default/files/campy-...
