background and aims: herpes simplex virus (hsv) is responsible for several significant human viral diseases, with severity ranging from subclinical to fatal infection. herpes simplex virus type 2 (hsv2) infections are more commonly seen in association with the genitalia and surrounding areas, and can be transmitted to newborns during childbirth. generalized infections in newborns are also predo...

Comparative analysis of the structural and possible non-structural proteins of seven Simbu serogroup bunyaviruses isolated in Australia revealed them all to be similar in size to those of Bunyamwera virus, the prototype of the Bunyavirus genus. The molecular weights of the structural proteins for these bunyaviruses (Akabane, Aino, Tinaroo, Douglas, Peaton, Facey's Paddock and Thimiri viruses) w...

Abstract Dengue virus (DENV 1–4) and Zika (ZIKV) are closely related flaviviruses that induce immunological cross-reactivity. The VRC5283 wild type DNA vaccine is the first to complete a Phase 2b trial (NCT03110770). objective of this study was test if induced potent ZIKV-specific neutralizing antibodies (NAbs) while avoiding priming cross-reactive could potentially enhance dengue disease. Here...

Serological diagnosis is a critical component for disease surveillance and is important to address the increase in incidence and disease burden of alphaviruses, such as the chikungunya (CHIKV) and Ross River (RRV) viruses. The gold standard for serological diagnosis is the plaque reduction neutralization test (PRNT), which demonstrates the neutralizing capacity of serum samples after the remova...

We developed a Rapid Diagnostic Test (RDT) kit for detecting IgG/IgM antibodies against Zika virus (ZIKV) using monoclonal antibodies to the envelope (E) and non-structural protein 1 (NS1) of ZIKV. These proteins were produced using baculovirus expression vector with Sf9 cells. Monoclonal antibodies J2G7 to NS1 and J5E1 to E protein were selected and conjugated with colloidal gold to produce th...

OBJECTIVES Enterovirus 71 (EV71) causes serious diseases in humans. The aim of this study was to examine the effects of aurintricarboxylic acid (ATA) on EV71 replication and to explore the underlying mechanism. METHODS To measure the activity of ATA in inhibiting the cytopathic effect (CPE) of EV71, a cell-based neutralization (inhibition of virus-induced CPE) assay was performed. The effect ...

Background and Aims: Herpes simplex virus type 1 (HSV1) remains a potentially serious health problem world wide. All infected people, including asymptomatic ones, are potential sources for virus transmission. Virus envelope contains at least 13 glycoproteins, which glycoprotein D is the major target of immune responses. The aim of this study was development of a specific method that is a more...

Nine virulent bacteriophages of the anaerobe Corynebacterium (Propionibacterium) acnes, the P-a series, are DNA phages, with long, curved nonretractile tails (130 nm) without tail plates or fibers. They have isometric heads (420 by 460 nm), and are placed in Bradley's group B-1. There is permanent plaque suppression at highest phage concentrations. After 100- to 1,000-fold dilution, plaques are...
