In this study, the antidengue virus activity of the ethanol extract from the leaves and twigs of E. cyathophora on four virus serotypes DENV1-DENV4 was examined. The result showed that the ethanol extract displayed antidengue activity on DENV1-4 with PRNT50 values of 15.625-62.5 µg/mL. This extract was fractionated to the n-hexane and ethyl acetate fractions.

The study of human B cell response to dengue virus (DENV) infection is critical to understand serotype-specific protection and the cross-reactive sub-neutralizing response. Whereas the first is beneficial and thus represents the ultimate goal of vaccination, the latter has been implicated in the development of severe disease, which occurs in a small, albeit significant, fraction of secondary DENV infections.

Listeriosis is associated with the consumption of contaminated food and has a higher incidence in the elderly, immunocompromised and pregnant. There are a few reported cases of pericarditis due to Listeria monocytogenes, with a high mortality.

Bệnh lở mồm long móng xảy ra trên heo tại Việt Nam chủ yếu là do virus lở mồm long móng thuộc serotype O. Hiệu quả của vacxin phòng bệnh lở mồm long móng không chỉ phụ thuộc vào serotype mà còn chịu ảnh hưởng của topotype của các chủng virus lở mồm long móng.

Infectious bronchitis virus (IBV), a coronavirus, is one of the most important poultry pathogens worldwide due to its multiple serotypes and poor cross-protection. Vaccination plays a vital role in controlling the disease. The efficacy of vaccination in chicken flocks can be evaluated by detecting neutralizing antibodies with the neutralization test. However there are no simple and rapid methods for detecting the neutralizing antibodies.

Marek’s disease (MD) is a lymphoproliferative disease caused by Gallid alphaherpesvirus 2 (GaHV-2, MDV-1), which primarily affects chickens. However, the virus is also able to induce tumors and polyneuritis in turkeys, albeit less frequently than in chickens.

The incidence and geographic range of dengue have increased dramatically in recent decades. Climate change, rapid urbanization and increased global travel have facilitated the spread of both efficient mosquito vectors and the four dengue virus serotypes between population centers.

Dengue virus serotyping is crucial for clinical management and epidemiology of the disease. As serotype shifts and secondary infection with a heterologous DENV serotype are frequently associated with disease severity, there is a need for sustained monitoring of the circulating serotypes and enhanced surveillance operations to prevent large scale severe dengue outbreaks.

Intervertebral disc (IVD) disorders are often accompanied by painful inflammatory and immunopathological processes. Nucleus pulposus (NP) cells play a pivotal role in maintenance of IVD by organizing the expression of anabolic, catabolic, anti-catabolic and inflammatory cytokines.

Dengue Fever is a mosquito-borne illness commonly present throughout the tropics. Dengue virus belongs to flaviviridae family and circulates with 4 different serotypes circulating in environment. In India four different serotypes of the virus are seen throughout country. The disease has a wide spectrum from an asymptomatic stage to DHF and DSS. Annually 100 million cases of dengue and a half million cases of DHF occurs worldwide with a case fatality of 0.5% to 3.5%. The combined laboratory interventions with the clinical spectrum can reduce the mortality in disease.

Bluetongue is an arthropod-borne, non-contagious viral disease of domestic and wild ruminants. In the present study, truncated VP2 protein of BTV serotype 23 (BTV-23) was expressed in a prokaryotic expression system and assessed for its potential use as a candidate for the development of serotype-specific BTV diagnostics assay. The expression of the VP2 protein was carried out in E. coli BL21 Codon Plus (DE3) cells using the pET32a expression vector.

Dengue Fever is a Flaviviral infection transmitted by the Aedes mosquitoes. It is a major public health issue in tropical and subtropical countries. Dengue virus is having four serotypes. It may progress to Dengue Hemorrhagic Fever, which can lead to Dengue Shock Syndrome and death. The study was conducted in the Department of Microbiology. K S. Hegde Medical Academy with the blood samples collected from the patients with clinical diagnoses of Dengue without any age or gender restriction. The samples were collected from the period of October 2015 to April 2017.

Foot-and-mouth disease is one of the important animal virus known to be highly infectious and causing a serious trade barrier. For effective control of FMD there is a need for in depth understanding of the virus epidemiology. The present study has been undertaken to understand the molecular relationship between the strains across world in comparison to Indian vaccine strain and virus isolate of 2010.

The present study was taken up with a view to undertake plaque purification of BTV-4 isolate available in the department, to confirm its purity. BTV-4 isolate was adapted to Vero cell line and had a titer of 106.46/ml after 8 passages in the process of plaque purification which was determined as 104.833/ml prior to adaption. Plaque purification was carried for three times using agarose overlaying method in 6 well plate. Each time plaques were observed from 4th day of infection of approximately not more than 1mm diameter.

Dengue is a viral disease spread to humans by mosquitoes. Notably, there are four serotypes of dengue viruses (DENV) that places ~40 % of the global population at risk of infection. However, lack of a suitable drug or a preventive vaccine exacerbates the matter further.

Four antigenically distinct serotypes (1–4) of dengue viruses (DENVs) cause dengue disease. Antibodies to any one DENV serotype have the potential to predispose an individual to more severe disease upon infection with a different DENV serotype.
