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.

In recent years, lasers with ultrashort pulses (USP) down to the femtosecond range have become established on an industrial scale. They could advance some applications with the much-lauded “cold ablation” – if that meant they would then achieve more throughput. A new generation of process engineering that will address this issue in particular will be discussed at the “4th UKP Workshop – Ultrafast Laser Technology” in April 2017.
Even back in the 1990s, scientists were comparing materials processing with nanosecond, picosecond and femtosesecond pulses. The result was surprising:...
Have you ever wondered how you see the world? Vision is about photons of light, which are packets of energy, interacting with the atoms or molecules in what...
A multi-institutional research collaboration has created a novel approach for fabricating three-dimensional micro-optics through the shape-defined formation of porous silicon (PSi), with broad impacts in integrated optoelectronics, imaging, and photovoltaics.
Working with colleagues at Stanford and The Dow Chemical Company, researchers at the University of Illinois at Urbana-Champaign fabricated 3-D birefringent...
In experiments with magnetic atoms conducted at extremely low temperatures, scientists have demonstrated a unique phase of matter: The atoms form a new type of quantum liquid or quantum droplet state. These so called quantum droplets may preserve their form in absence of external confinement because of quantum effects. The joint team of experimental physicists from Innsbruck and theoretical physicists from Hannover report on their findings in the journal Physical Review X.
“Our Quantum droplets are in the gas phase but they still drop like a rock,” explains experimental physicist Francesca Ferlaino when talking about the...
The Max Planck Institute for Physics (MPP) is opening up a new research field. A workshop from November 21 - 22, 2016 will mark the start of activities for an innovative axion experiment. Axions are still only purely hypothetical particles. Their detection could solve two fundamental problems in particle physics: What dark matter consists of and why it has not yet been possible to directly observe a CP violation for the strong interaction.
The “MADMAX” project is the MPP’s commitment to axion research. Axions are so far only a theoretical prediction and are difficult to detect: on the one hand,...
