Stool samples were obtained from eight different hospitals in Peninsular Malaysia. Out of 168 stool samples examined, 45.8% were from children less than 5 years old and 22% were antigen positive. Due to small amount of fecal material left from this age bracket, NoV was not screened since it is already known that 90% in this age group are often infected with rotavirus (RV), which is the most common cause of severe diarrhoea in children.
From the remaining total screened, only 89% were screened for NoV and 9.3% were NoV genogroup II. By phylogenetic analysis, GII/3 and GII/4 were found to be the prevalent strains. Majority of these samples were closely related to GII/4 Nagano 2007/JP strains from Japan and one was closely related to GII/4 from Bristol, UK.
This study also provides valuable information on NoV genotype , which could be used for surveillance and vaccine strategy. The presence of both GII.4 and GII.3 are in concordance to other strains reported elsewhere in the world. This novel GII.4 variant, termed Hunter virus (Bull et al., 2006) have been identified as the etiological agent in 18 outbreaks investigated including The Netherlands, Japan and Taiwan in 2004 and 2005.This study is the first report of NoV in lettuces in Malaysia. This preliminary study should be continued since NoV is now being identified as one of the common cause of diarrhea and is still under reported in Malaysia.

For the first time ever, scientists have determined the cosmic origin of highest-energy neutrinos. A research group led by IceCube scientist Elisa Resconi, spokesperson of the Collaborative Research Center SFB1258 at the Technical University of Munich (TUM), provides an important piece of evidence that the particles detected by the IceCube neutrino telescope at the South Pole originate from a galaxy four billion light-years away from Earth.
To rule out other origins with certainty, the team led by neutrino physicist Elisa Resconi from the Technical University of Munich and multi-wavelength...
For the first time a team of researchers have discovered two different phases of magnetic skyrmions in a single material. Physicists of the Technical Universities of Munich and Dresden and the University of Cologne can now better study and understand the properties of these magnetic structures, which are important for both basic research and applications.
Whirlpools are an everyday experience in a bath tub: When the water is drained a circular vortex is formed. Typically, such whirls are rather stable. Similar...
Physicists working with Roland Wester at the University of Innsbruck have investigated if and how chemical reactions can be influenced by targeted vibrational excitation of the reactants. They were able to demonstrate that excitation with a laser beam does not affect the efficiency of a chemical exchange reaction and that the excited molecular group acts only as a spectator in the reaction.
A frequently used reaction in organic chemistry is nucleophilic substitution. It plays, for example, an important role in in the synthesis of new chemical...
Optical spectroscopy allows investigating the energy structure and dynamic properties of complex quantum systems. Researchers from the University of Würzburg present two new approaches of coherent two-dimensional spectroscopy.
"Put an excitation into the system and observe how it evolves." According to physicist Professor Tobias Brixner, this is the credo of optical spectroscopy....
Ultra-short, high-intensity X-ray flashes open the door to the foundations of chemical reactions. Free-electron lasers generate these kinds of pulses, but there is a catch: the pulses vary in duration and energy. An international research team has now presented a solution: Using a ring of 16 detectors and a circularly polarized laser beam, they can determine both factors with attosecond accuracy.
Free-electron lasers (FELs) generate extremely short and intense X-ray flashes. Researchers can use these flashes to resolve structures with diameters on the...
