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.

Once invincible superbug squashed by 'superteam' of antibiotics

Whether you call it effervescent, fizzy, or sparkling, carbonated water is making a comeback as a beverage. Aside from quenching thirst, researchers at the University of Illinois at Urbana-Champaign have discovered a new use for these "bubbly" concoctions that will have major impact on the manufacturer of the world's thinnest, flattest, and one most useful materials -- graphene.
As graphene's popularity grows as an advanced "wonder" material, the speed and quality at which it can be manufactured will be paramount. With that in mind,...
Physicists at the University of Bonn have managed to create optical hollows and more complex patterns into which the light of a Bose-Einstein condensate flows. The creation of such highly low-loss structures for light is a prerequisite for complex light circuits, such as for quantum information processing for a new generation of computers. The researchers are now presenting their results in the journal Nature Photonics.
Light particles (photons) occur as tiny, indivisible portions. Many thousands of these light portions can be merged to form a single super-photon if they are...
For the first time, scientists have shown that circular RNA is linked to brain function. When a RNA molecule called Cdr1as was deleted from the genome of mice, the animals had problems filtering out unnecessary information – like patients suffering from neuropsychiatric disorders.
While hundreds of circular RNAs (circRNAs) are abundant in mammalian brains, one big question has remained unanswered: What are they actually good for? In the...
An experimental small satellite has successfully collected and delivered data on a key measurement for predicting changes in Earth's climate.
The Radiometer Assessment using Vertically Aligned Nanotubes (RAVAN) CubeSat was launched into low-Earth orbit on Nov. 11, 2016, in order to test new...
A study led by scientists of the Max Planck Institute for the Structure and Dynamics of Matter (MPSD) at the Center for Free-Electron Laser Science in Hamburg presents evidence of the coexistence of superconductivity and “charge-density-waves” in compounds of the poorly-studied family of bismuthates. This observation opens up new perspectives for a deeper understanding of the phenomenon of high-temperature superconductivity, a topic which is at the core of condensed matter research since more than 30 years. The paper by Nicoletti et al has been published in the PNAS.
Since the beginning of the 20th century, superconductivity had been observed in some metals at temperatures only a few degrees above the absolute zero (minus...
