River biomonitoring uses biotic indices that assess human-induced degradation, including pollution, by comparison with type-specific static biological reference conditions. However, index scores indicate pollution may reflect responses to natural hydrological variability associated low flows and drying, leading schemes misclassify sites as degraded. To address this, dynamic, site-specific adjus...

BACKGROUND Recently, newly defined clades of Mycobacterium tuberculosis complex (MTBC) strains, namely Ethiopia 1-3 and Ethiopia H37Rv-like strains, and other clades associated with pulmonary TB (PTB) were identified in Ethiopia. In this study, we investigated whether these new strain types exhibit an increased ability to cause TB lymphadenitis (TBLN) and raised the question, if particular MTBC...

Correspondence Emergence of an Autochthonous and Community-Acquired NDM-1–Producing Klebsiella pneumoniae in Europe To the Editor—The recently identi-tified carbapenemase New Dehli metallo-b-lactamase (NDM-1) in-activates all b-lactams except az-treonam [1]. The corresponding gene that is usually plasmid-borne has spread mostly in Escherichia coli and Klebsiella pneumoniae [1, 2]. NDM-1 produce...

While global fears mount about the dwindling numbers of many amphibian species as a result of disease and other unknown factors, three separate teams of researchers have announced the discovery of several new species and other organisms in the mountain rainforests of Colombia, Tanzania and India. Scientists in Bogata carried out a ‘rapid assessment program’ expedition over three weeks in the mo...
