Some badnaviruses are known to occur as endogenous viruses integrated into their host genome. In the present study, Piper yellow mottle virus (PYMoV), a badnavirus infecting black pepper was shown to occur as endogenous virus based on the PCR, reverse transcription (RT)-PCR, ELISA and Southern hybridization tests. Black pepper plants that tested positive in PCR for PYMoV gave negative reaction in RT-PCR indicating that they harbour endogenous PYMoV (ePYMoV) sequences. The RT-PCR (-ve) plants tested negative in ELISA and also in PCR using outword primers to amplify the full circular genome...

Acute encephalitis caused by the Japanese encephalitis virus (JEV) represents a growing epidemic and is a cause for concern in Southeast Asia. JEV is transmitted to humans through the bite of the Culicine mosquito species. The virus genome comprising of an RNA strand also encodes the envelope protein (E) which surrounds the virus. The E protein aids in fusion of virus with the cellular membrane of the host cell with the help of three structurally distinct domains (DI, DII, DIII) that are connected by flexible hinge regions...

Ano-genital warts are considered one of the commonest and highly infectious sexually transmitted infections. These warts are primarily caused by the human papillomavirus (HPV) of the family Papillomaviridae, genus alpha-papillomavirus, species 10 and types 6 and 11. However the high recurrence rate of warts is a matter of serious concern to the patients and a challenge for the treating physician. The conventional treatment options are targeted only to the local site of warts. There is no systemic treatment modality as there is limited understanding of the disease immune-pathogenesis...

Coxsackievirus (CV) is a member of the genus Enterovirus and the family Picornaviridae. CV infection can cause herpangina, a disease characterized by multiple ulcers on the tonsils and soft palate affecting mostly young children. CV strains are categorized by serotypes. Unfortunately, serotypes responsible for infections in patients are often undetermined. This knowledge gap partly contributes to the ineffective prevention and control of CV-associated herpangina in Southeast Asia. To characterize the viral etiology of children presented with herpangina, 295 throat swabs were tested for human enterovirus infection...
