Investigations on the possible impact of a glyphosate-containing herbicide on ruminal metabolism and bacteria in vitro by means of the 'Rumen Simulation Technique'.

Aims: This study was performed in a well-established in vitro model to investigate whether the application of a glyphosate-containing herbicide might affect the bacterial communities and some biochemical parameters in a cow's rumen.

Methods And Results: The test item was applied in two concentrations (high and low) for 5 days. In a second trial, fermentation vessels were inoculated with Clostridium sporogenes before the high dose was applied.

Molecular epidemiology of Salmonella enterica serovar Kottbus isolated in Germany from humans, food and animals.

Salmonella enterica serovar Kottbus has been continuously isolated from poultry and poultry meat, especially from turkey. We investigated by comparative molecular typing 95 S. Kottbus isolates obtained in Germany between 2000 and 2011 from poultry/poultry meat, pig/pork, cattle, reptiles, the environment as well as from human cases to identify potential infection sources for humans, especially the role of poultry and poultry products as vehicle in transmission of S.

Population structure of Salmonella enterica serovar 4,[5],12:b:- strains and likely sources of human infection.

Salmonella enterica serovar 4,[5],12:b:- is a monophasic serovar not able to express the second-phase flagellar antigen (H2 antigen). In Germany, the serovar is occasionally isolated from poultry, reptiles, fish, food, and humans. In this study, a selection of 67 epidemiologically unrelated Salmonella enterica serovar 4,[5],12:b:- strains isolated in Germany between 2000 and 2011 from the environment, animal, food, and humans was investigated by phenotypic and genotypic methods to better understand the population structure and to identify potential sources of human infections.

Human infections attributable to the D-tartrate-fermenting variant of Salmonella enterica serovar Paratyphi B in Germany originate in reptiles and, on rare occasions, poultry.

In this study, the population structure, incidence, and potential sources of human infection caused by the d-tartrate-fermenting variant of Salmonella enterica serovar Paratyphi B [S. Paratyphi B (dT+)] was investigated. In Germany, the serovar is frequently isolated from broilers.

Clonal dissemination of Salmonella enterica serovar Infantis in Germany.

Salmonella enterica serovar Infantis (Salmonella Infantis) is consistently isolated from broiler chickens, pigs, and humans worldwide. This study investigated 93 epidemiologically unrelated Salmonella Infantis strains isolated in Germany between 2005 and 2008 in respect to their transmission along the food chain. Various phenotypic and genotypic methods were applied, and the pathogenicity and resistance gene repertoire was determined.
