The virucidal activity of chlorine-compounds was studied using hepatitis A virus (HAV) and Poliovirus 2 and comparing the disinfectant efficiency of peracetic acid. HAV presented a higher resistance to HClO than Poliovirus did. With ClO2 the inactivation times of HAV were markedly shorter. A comparison between these data and those resulting from the kinetics with peracetic acid (PA) showed that...

For three decades now, ionic liquids (ILs), organic salts comprising only ions, have emerged as a new class of pharmaceuticals. Although recognition of the antimicrobial effects of ILs is growing rapidly, there is almost nothing known about their possible virucidal activities. This probably reflects the paucity of understanding virus inactivation. In this study, we performed a systematic analys...

A novel non-ionic surfactant nanoemulsion designated 8N8 has been tested for its biocidal activity. One percent 8N8 produced effective bactericidal activity against Bacillus cereus, Bacillus subtilis, Haemophilus influenzae, Neisseria gonorrhoeae, Streptococcus pneumoniae, and Vibrio cholerae in 15 minutes. In contrast, most enteric gram-negative bacteria were resistant to 8N8. One percent 8N8 ...

The potent antibacterial and antiviral activity of petroleum ether, ethyl acetate, successive and crude methanolic extracts of J. curcas leaves was evaluated. The antibacterial activity of J. curcas extracts was studied against 6 common foods borne bacteria using disc diffusion assay. The antibacterial activity of J. curcas extracts showed different degrees of inhibition zone against the pathog...

Although nuimerous studies have been reported on the virucidal activity of' various substances used as aerosolic mists or in direct contact with the influenza virus, only two studies have been published describing the action of vapors on viruses, so far as the writers are aware. Remlinger and Bailly (1942) showed that when the viruses of rabies, pseudorabies, or eastern equine encephalomyelitis...

Hypochlorous acid (HOCl) solutions were evaluated for their virucidal ability against a low pathogenic avian influenza virus (AIV), H7N1. HOCl solutions containing 50, 100 and 200 ppm chlorine (pH 6) or their sprayed solutions (harvested in dishes placed at 1 or 30 cm distance between the spray nozzle and dish) were mixed with the virus with or without organic materials (5% fetal bovine serum: ...

Essential oils from anise, hyssop, thyme, ginger, camomile and sandalwood were screened for their inhibitory effect against herpes simplex virus type 2 (HSV-2) in vitro on RC-37 cells using a plaque reduction assay. Genital herpes is a chronic, persistent infection spreading efficiently and silently as sexually transmitted disease through the population. Antiviral agents currently applied for t...

BACKGROUND New sources for discovering novel antiviral agents are desperately needed. The current antiviral products are both expensive and not very effective. METHODS The antiviral activity of methanol extract of mung bean sprouts (MBS), compared to Ribavarin and Acyclovir, on respiratory syncytial virus (RSV) and Herpes Simplex virus -1 (HSV-1) was investigated using cytotoxicity, virus yie...
