Backgrounds Justicia gendarussa Burm.f. has an anti-HIV activity. This study was conducted to evaluate the effects of incubation periods on the cytotoxicity and virucidal activities of the J. gendarussa leaves extract on MOLT-4 cells. Materials and Methods The cytotoxicity assay was evaluated by using the WST-1 test with incubation periods of 3 days and 5 days. The virucidal activity test was...

Fresh water obtained from nine sources was shown to cause inactivation of poliovirus. Further testing with four of these water samples showed that enteric viruses from different genera were consistently inactivated in these freshwater samples. Studies on the cause of inactivation were conducted with echovirus type 12 as the model virus. The results revealed that the virucidal agents in the wate...

Antimicrobial liquids and foams were applied to the hands to determine their virucidal activity against rhinoviruses. Dilute solutions (1%) of iodine in ethyl alcohol or in water were most effective in causing inactivation of rhinovirus when applied immediately after viral contamination. Iodine also had a residual virucidal activity which persisted on the hands for up to 1 h. Less effective ina...

BACKGROUND The recent Ebola virus (EBOV) epidemic highlights the need for efficacious virucidal products to help prevent infection and limit the spread of Ebola virus disease. However, there is limited data on the efficacy of virucidal products against EBOV, because the virus has a high biosafety level and is only available in a few laboratories worldwide. The virucidal efficacy of antiseptics ...

Herpes simplex virus type 2 and simian virus 40 were rapidly inactivated by retinal at micromolar concentrations. Other fat-soluble vitamins, particularly vitamin A derivatives, were also active against herpes simplex virus type 2 and several lipid-containing bacteriophages.

Purpose: To determine the cytotoxic and antiviral potentials of Euphorbia milii var. splendens leaf against Peste des petits ruminants virus (PPRV).
 Methods: The methanol extract, as well n- hexane, chloroform, ethyl acetate, butanol fractions E. leaves were screened for activities PPRV using Vero cell line 3-(4,5-dimethylthiazol-2-yl)-2,diphenyltetrazolium bromide (MTT) assay.

A mixture of benzalkonium chloride, Triton X100, and citric acid (Resiguard F) had a marked virucidal effect on lipid-containing deoxyribonucleic and ribonucleic acid viruses, such as vaccinia virus, herpesvirus, and influenza virus. Adenoviruses and picornaviruses were more resistant to inactivation. Electron microscopy showed that influenza particles became aggregated in the presence of Resig...

The bactericidal activity of 3-propiolactone (BPL) vapor was first reported by Hoffman and Warshowsky (1958). Although this chemical has shown promise in our laboratories as a very useful gaseous disinfectanit for rooms and buildings, the lack of information on the virucidal activity of BPL vapor has been a deterrent in the use of the chemical to decontaminate virology laboratories or buildings...
