Monolaurin has a good inhibitory effect on Clostridium perfringens, Streptococcus, Campylobacter. The mechanism of α-monolaurin antiviral is that lauric acid can cause membrane protein leakage of the virus, and monolaurin can be inserted into the envelope of the virus, and these effects can lead to a decrease or loss of replication ability. Monolaurin destroys the membrane structure of the virus and inhibits the ability of the virus to replicate. The viruses of AIDS, PRRS, and swine fever are the same as enveloped viruses.
