[Diagnostic reliability of anaerobic blood cultures in bacteremias from a critical care unit].

Background And Objective: This is a descriptive study of bacteraemias diagnosed in ICU with an analysis of the diagnostic reliability of anaerobic blood cultures.

Patients And Method: Analysis of all positive blood cultures in an Intensive Care Unit from May 2005 to October 2007.

Geckos as indicators of mining pollution.

Catastrophic collapse of a mine tailings dam released several million cubic meters of toxic mud and acidic water into the Guadiamar River valley, southern Spain, in 1998. Remediation efforts removed most of the sludge from the floodplain, but contamination persists. Clean-up activities also produced clouds of aerosolized materials that further contaminated the surrounding landscape.
