| A virus that causes cold-like symptoms in humans originated in birds and may have crossed the species barrier around 200 years ago, according to an article in the Journal of General Virology. Scientists hope their findings will help us understand how potentially deadly viruses emerge in humans. |

| • | Effects of pre-commercial thinning on transpiration in young post-fire maritime pine stands |
|
In the present study, the effect of heavy thinning on soil water content was investigated in relation to water use in an 8-year-old post-fire-regenerated maritime pine (Pinus pinaster Ait.) stand in northwestern Spain over two growing seasons. Three different treatment levels were selected: control (unthinned, 40 200 saplings ha–1), intense thinning (leaving 3850 saplings ha–1) and very intense thinning (leaving 1925 saplings ha–1); sap flow measurements were made on 10 saplings in each treatment throughout two growing seasons following thinning. Soil water availability in thinned plots was 1.8 times higher in the first growing season and 2.5 times higher in the second season, than in the control plots. Sap flow density in very intensely thinned plots was lower than in the control plots 3–5 months after treatment. However, for the whole study period the mean sap flow density in saplings was higher in thinned plots than in unthinned plots (about double in the first growing season and 1.7 times higher in the second). Monthly transpiration at plot level was 8.8 and 4.4 times higher in control plots, than in very intensely and intensely thinned plots, respectively, in the first growing season, and 4.5 and 2.8 in the second season. Very intense thinning did not result in significant differences in saplings sap flow and transpiration at plot level, compared with intense thinning. Some consequences of these results for the management of such juvenile stands are discussed. |

| • | Emergence of ampicillin-resistant Enterococcus faecium in Danish hospitals |
|
Ampicillin-resistant Enterococcus faecium isolates are reported in increasing numbers in many European hospitals. The clonal complex 17 (CC17) characterized by ampicillin resistance has been associated with nosocomial E. faecium outbreaks and infections in five continents. The aim was to investigate how prevalent ampicillin resistance is in clinical E. faecium isolates from Denmark and to investigate their clonal affiliation, especially to CC17. Microbiology data from 2002 through 2006 on E. faecium and Enterococcus faecalis blood isolates was received from Departments of Clinical Microbiology in 11 Danish counties. From January 2004 through December 2004, we collected 275 clinical enterococci from four of these departments. Multilocus sequence typing (MLST) and PFGE were performed on the 84 ampicillin-resistant E. faecium isolates from this collection. A 68% increase in the number of infections caused by enterococci was observed from 2002 through 2006. The increase was mainly caused by E. faecium isolates, which tripled, whereas the number of E. faecalis isolates increased by only 23% during the same period. There was also a significant increase in the number of ampicillin-resistant E. faecium isolates. MLST showed that 98% of the tested ampicillin-resistant E. faecium isolates belonged to CC17. PFGE showed eight different clusters and we found indications of clonal spread within the hospitals. Ampicillin-resistant E. faecium isolates have increased in frequency in Denmark during 2002–2006. Most of the ampicillin-resistant E. faecium isolates belong to complex CC17. |
