Successful systemic infection of a plant by Tobacco mosaic virus (TMV) requires three processes that repeat over time: initial establishment and accumulation in invaded cells, intercellular movement, and systemic transport. Accumulation and intercellular movement of TMV necessarily involves intracellular transport by complexes containing virus and host proteins and virus RNA during a dynamic pr...

The asymptomatic phase of HIV-1 infections is characterised by a stable set-point viral load (SPVL) within patients. The SPVL is a strong predictor of disease progression and shows considerable variation of multiple orders of magnitude between patients. Recent studies have found that the SPVL in donor and recipient pairs is strongly correlated indicating that the virus genotype strongly influen...

In this paper, we studied a mathematical model of tuberculosis with vaccination for the treatment tuberculosis. We considered an in-host that described interaction between Macrophages and Mycobacterium investigated effect treatments on uninfected macrophages. Optimal control is applied to show optimal effective strategies disease. The formula obtained using Hamiltonian function Pontryagin's max...

BACKGROUND: West Nile virus (WNV) is a vector-borneagent that is maintained within a bird-mosquito cycle. In humansand equids, infection by this agent is usually asymptomatic, orcharacterized by a mild febrile illness. However, fatal meningoencephalitisor encephalitis may occur. OBJECTIVES:The aim ofthis study was to evaluate the prevalence of WNVinfection andcorrelation of this organism with h...
