Clonal CTX-M-15-Producing ST-949 Are Present in German Surface Water.

Extended-spectrum beta-lactamase (ESBL)-producing bacterial isolates are emerging within the last years. To understand this emergence, a thorough genome-based analysis of ESBL isolates from different sources (One Health approach) is needed. Among these, analysis of surface water is underrepresented.

[Measuring the spread of airborne microorganisms in the area of composting sites].

Emission concentrations of culturable microorganisms were determined in the vicinity of three open or partly encapsulated composting facilities. Sampling was performed during so-called worst case situations which should promote aerial transport of emissions. Suitability of thermophilic organisms to detect an emitting influence of the plant was confirmed.

["Microbial air pollutants--methods for detection of endotoxins, mycotoxins and MVOC"].

In the context of microbial emissions from composting facilities the methods for the detection and identification of the groups of substances released, i.e. endotoxins, mycotoxins and Microbial Volatile Compounds (MVOC) are discussed.

[Claims of machine decontamination of dishes under hygienic conditions and of a small load in sewage--a contradiction?].

To make sure, whether the hygienic requirements and the ecotoxicologic ones are excluding each other or not, several studies in dishwashing machines under practical conditions have been done. The requirements from the hygienic point of view have been fixed at a 5 lg--reduction of E. faecium ATCC 6057 in a mixture of bovine albumin, mucin and starch as interfering substances on well defined test items.
