2012–13 Upcoming meetings

The Winter 2012–13 conference season provides ample opportunities to attend meetings that feature topics relevant to antibody research and development (R&D). Meetings such as these serve critical informational and educational functions and are key networking opportunities. Locations are spread throughout the world, reflecting the global nature of antibody R&D.

Please note that Upcoming meetings lists will no longer be included in the print version of mAbs starting with the January/February 2013 issue. Please visit the mAbs home page to find an online meeting list: www.landesbioscience.com/journals/mabs/     

Novel Respiratory Syncytial Virus (RSV) Genotype ON1 Predominates in Germany during Winter Season 2012–13

Respiratory syncytial virus (RSV) is the leading cause of hospitalization especially in young children with respiratory tract infections (RTI). Patterns of circulating RSV genotypes can provide a better understanding of the molecular epidemiology of RSV infection. We retrospectively analyzed the genetic diversity of RSV infection in hospitalized children with acute RTI admitted to University Hospital Heidelberg/Germany between October 2012 and April 2013. Nasopharyngeal aspirates (NPA) were routinely obtained in 240 children younger than 2 years of age who presented with clinical symptoms of upper or lower RTI. We analyzed NPAs via PCR and sequence analysis of the second variable region of the RSV G gene coding for the attachment glycoprotein. We obtained medical records reviewing routine clinical data. RSV was detected in 134/240 children. In RSV-positive patients the most common diagnosis was bronchitis/bronchiolitis (75.4%). The mean duration of hospitalization was longer in RSV-positive compared to RSV-negative patients (3.5 vs. 5.1 days; p<0.01). RSV-A was detected in 82.1%, RSV-B in 17.9% of all samples. Phylogenetic analysis of 112 isolates revealed that the majority of RSV-A strains (65%) belonged to the novel ON1 genotype containing a 72-nucleotide duplication. However, genotype ON1 was not associated with a more severe course of illness when taking basic clinical/laboratory parameters into account. Molecular characterization of RSV confirms the co-circulation of multiple genotypes of subtype RSV-A and RSV-B. The duplication in the G gene of genotype ON1 might have an effect on the rapid spread of this emerging RSV strain.

David Alan Walker (1928–2012)

David Alan Walker, Emeritus Professor of Biology, University of Sheffield, UK and Fellow of the Royal Society, died on February 13, 2012. David had a marvelous 60?year career as a scientist, during which he was a researcher, mentor, valued colleague, and a prolific writer in the field of photosynthesis. His career was marked by creative breakthroughs in isolation and analysis of chloroplast metabolism in vitro and simple but valuable technical advances for measurement of photosynthesis in vivo that remain relevant on a global scale to production of crops and biofuels, as well as plant responses to climate change. We include here personal remembrances by the authors (GEE and UH), and by (in alphabetical order): Zoran Cerovic (France), Bob Furbank (Australia), Geoffrey Hind (USA), John Humby (UK), Agu Laisk (Estonia), Peter Lea (UK), Ross Lilley (Australia), Barry Osmond (Australia), Simon Robinson (Australia) and Charles Stirling (UK).     

Metabolism of Aniline by Rhodococcus erythropolis AN–13

The metabolic pathway of aniline was examined in Rhodococcus erythropolis AN-13 that was isolated from soil when aniline was provided as a sole source of carbon and nitrogen. cis, cis-Muconic acid and β-ketoadipic acid were detected by thin-layer chromatography in an incubation mixture containing aniline and resting cells of this strain. These two carboxylic acids were also formed from catechol, when the substrate was incubated with cell-free extract of aniline-grown cells, and characterized spectrally as crystalline samples. Ammonia was released from aniline by resting cells. The cell-free extract of aniline-grown cells had a strong catechol 1,2-dioxygenase activity. Catechol, once formed from aniline, was apparently converted so rapidly to cis, cis-muconic acid that it could not be isolated. These results suggest that R. erythropolis AN-13 converted aniline to catechol with the release of ammonia and then mineralized catechol ultimately to inorganic end products, H₂O and CO₂, through the β ketoadipic acid pathway.
