Before the advent of molecular biology methods, studies of pathogens were dominated by analyses of their metabolism. Development of molecular biology techniques then enabled the identification and functional characterisation of the fascinating toolbox of virulence factors. Increasing, genomic and proteomic approaches form the basis for a more systemic view(More)
The natural habitats and potential reservoirs of the nosocomial pathogen Acinetobacter baumannii are poorly defined. Here, we put forth and tested the hypothesis of avian reservoirs of A. baumannii. We screened tracheal and rectal swab samples from livestock (chicken, geese) and wild birds (white stork nestlings) and isolated A. baumannii from 3% of sampled(More)
Acinetobacter baumannii is a Gram-negative bacterium appearing as an opportunistic pathogen in hospital settings. Superoxide dismutase (SOD) contributes to virulence in several pathogenic bacteria by detoxifying reactive oxygen species released in the course of host defense reactions. However, the biological role of SODs in A. baumannii has not yet been(More)
The glycolytic enzyme pyruvate kinase (PK) generates ATP from ADP through substrate-level phosphorylation powered by the conversion of phosphoenolpyruvate to pyruvate. In contrast to other bacteria, Enterobacteriaceae, such as pathogenic yersiniae, harbour two pyruvate kinases encoded by pykA and pykF. The individual roles of these isoenzymes are poorly(More)
