The incidence of Cherry necrotic rusty mottle virus (CNRMV) and Cherry green ring mottle virus (CGRMV) have recently been occurred in Korea, posing a problem for sweet cherry cultivation. Since infected trees have symptomless leaves or ring-like spots on the pericarp, it is difficult to identify a viral infection. In this study, the incidence of CNRMV and CGRMV in sweet cherry in Gyeongbuk prov...

Interactions between viral proteins are critical for virus viability. Bimolecular fluorescent complementation (BiFC) technique determines protein interactions in real-time under almost normal physiological conditions. The coat protein (CP) of Prunus necrotic ringspot virus is required for multiple functions in its replication cycle. In this study, the region involved in CP dimerization has been...

rhizomania is one of the most important sugar beet diseases in iran and some other parts of the world. in this study, the infection rate of the most important weeds of sugar beet fields under natural condition  to the causal agent of the bnyvv (beet necrotic yellow vein virus) disease  was investigated at fars agricultural research center , iran. roots were collected from the infected weeds and...

Viral hepatitis C is a major problem of post-transfusion hepatitis. The best measure for preventing hepatitis C infection in transfusion is blood donor screening. There are many methods for detecting hepatitis C virus antibodies. ELISA is one of the sensitive screening methods. However it needs equipment, technical skills and it is time consuming. The Genelabs Diagnostics HCV-SPOT is a simple, ...

Microscopic Agglutination Test is the standard test employed in centres for confirming the cause of the disease (Levett, 2001; WHO, 2003). This test requires a panel of locally prevalent live leptospires which has to be maintained for routine procedures. The procedure is very laborious, time consuming and may cause cross infections in laboratories (WHO, 2003; Cumberland, 1999), following which ...

measles, rubella, mumps, hepatitis b virus (hbv) and varicella zoster virus (vzv) cause infectious diseases that can be effectively prevented by vaccination. vaccination of medical students is important, because they are more likely to become exposed and infected by these viruses. a total of 180 students, consisting of 90 women and 90 men, were serologically screened for measles, rubella and mu...

A new disorder was observed on southern highbush blueberries in several south-eastern states in the USA. Symptoms included irregularly shaped circular spots or blotches with green centres on the upper and lower surfaces of leaves. Double-stranded RNA was extracted from symptomatic leaves suggesting the presence of virus(es) possibly involved in the disease. Sequencing revealed the presence of a...
