Phosphorus was added as a nutrient to bench-scale and pilot-scale biologically active carbon (BAC) reactors operated for perchlorate and nitrate removal from contaminated groundwater. The two bioreactors responded similarly to phosphorus addition in terms of microbial community function (i.e., reactor performance), while drastically different responses in microbial community structure were dete...

Probiotic supplements transform the intestinal microbial flora and enhancing gut and immune function. The intestinal microbial flora the gastrointestinal tract. These bacteria are integral to the protection of the body from infection, and maintenance of intestinal homeostasis. The microbial flora with intestinal epithelial cells and immune tract, skin and uro-genital tract. The exercise highlig...

Developing countries of the world are alarmed by the focus of the developed countries upon disinfection by-products (DBPs) that are potentially harmful to human health, particularly those due to chlorination. In many economically disadvantaged countries chlorination is currently the only affordable barrier against the transmission of waterborne disease: their only choice is between microbiologi...

Microbial surveillance systems have varied in their source of support; type of laboratory reporting (patient care or reference); inclusiveness of reports filed; extent of microbial typing; whether single hospital, multihospital, or multicountry; proportion of total medical centers participating; and types, levels, integration across levels, and automation of analyses performed. These surveillan...

The knowledge of the survival of inoculated fungal and bacterial strains in field and the effects of their release on the indigenous microbial communities has been of great interest since the practical use of selected natural or genetically modified microorganisms has been developed. Soil inoculation or seed bacterization may lead to changes in the structure of the indigenous microbial communit...

The metallic low and intermediate level radioactive waste generally consists of carbon steel and stainless steels. The corrosion rate of carbon steel in deep groundwater is typically low, unless the water is very acidic or microbial activity in the environment is high. Therefore, the assessment of microbially induced corrosion of carbon steel in deep bedrock environment has become important for...

Streptococcus salivarius is a prominent member of the oral microbiota and has excellent potential for use as a probiotic targeting the oral cavity. In this report we document safety data relating to S. salivarius K12, including assessment of its antibiogram, metabolic profiles, and virulence determinants, and we examine the microbial composition of saliva following the dosing of subjects with K12.

1. The Defra Antimicrobial Resistance Coordination Group has prepared the attached paper summarising the actions taken to address the recommendations in the ACMSF 1999 Report on Microbial Antibiotic Resistance in Relation to Food Safety. Members may wish to read this paper in conjunction with the recommendations and Government’s response paper which has been circulated as an Information Paper (...

Here, we report the availability of draft genomes of several Salmonella serotypes, isolated from poultry sources from Nigeria. These genomes will help to further understand the biological diversity of S. enterica and will serve as references in microbial trace-back studies to improve food safety.

The genome sequencing of 13 Salmonella enterica subsp. enterica serovar Lubbock strains isolated from liver abscesses of feedlot cattle is reported here. The availability of these genomes will help to further understand the etiologic role of Salmonella strains in liver abscesses of cattle and will serve as references in microbial trace-back studies to improve food safety.
