objective: the brucella melitensis virb operon, encoding a type iv secretion system (t4ss), is required for intracellular replication and persistent infection in the mouse model. the product of the second gene of the virb operon, virb2, is predicted to be localized at the bacterial surface, where they could potentially interact with host cells. studies to date have focused on characterization o...

SRC kinases and PKR are intracellular protein kinases, which play key roles in intracellular viral replication. In this research, the effect of SRC kinase inhibition and PKR activation and inhibition on replication of coxsakievirus (CVB3), an entrovirus of the family picornaviridae – causative agents of fatal myocarditis, was studied. Vero and Hela cells were cultured and infected with CVB3 in ...

Several phytochemicals exhibited high level of antiviral activity. Medicinal plant possessed activity via many mechanisms included inhibition viral replication, the assembly intracellular infectious virus particles, infectivity, RNA polymerase, DNA neuraminidase, protease, reverse transcriptase and protein expression other mechanisms. The current review discuss medicinal plants with their action.

The intracellular replication of MVL51, a group L1 mycoplasmavirus, was investigated. The single-stranded parental DNA was found to enter the cell and become converted to double-stranded DNA. This replicated to yield additional double-stranded DNA molecules. The parental viral DNA was found to leave the replication complex and become associated with large molecular weight DNA not involved with ...

Legionella pneumophila grows within cells ranging from environmental amoebae to human macrophages. In spite of this conserved strategy of pathogenesis, identification of host factors that restrict L. pneumophila intracellular replication has not been extended outside components of the mammalian innate immune response. We performed a double-stranded RNA (dsRNA) screen against more than 50% of th...
